Rare March tornado rips Michigan; record March heat wave sets more records

As I stepped out of my front door into the pre-dawn darkness from my home near Ann Arbor, Michigan yesterday morning, I braced myself for the cold shock of a mid-March morning. It didn't come. A warm, murky atmosphere, with temperatures in the upper fifties--30 degrees above normal--greeted me instead. Continuous flashes of heat lightning lit up the horizon, as the atmosphere crackled with the energy of distant thunderstorms. Beware the Ides of March, the air seemed to be saying. I looked up at the hazy stars above me, flashing in and out of sight as lightning lit up the sky, and thought, this is not the atmosphere I grew up with.


Video 1. Video taped at Hudson Mills Metro Park in Dexter about 5:30PM on March 15, 2012, by Matthew Altruda from Tree Town Sound, http://www.treetownsound.com. Caution: foul language.

That afternoon, as the Detroit temperature soared to 77°F, the second warmest on record so early in the year, going back to 1871, I watched as late afternoon thunderstorms built with remarkable speed. Though NOAA's Storm Prediction Center had placed Southeast Michigan in their "Slight Risk" area for severe weather, I wasn't too concerned about tornadoes. We don't get many tornadoes in Michigan this early in the year, and certainly not strong ones. Prior to yesterday, there were only sixteen tornadoes on record in Michigan that occurred before March 16, going back to 1950. Though the air was remarkably unstable for this time of year, the upper level winds were not strong enough to generate much shearing action on the air, meaning that tornadoes would have a tough time getting spinning. But the atmosphere had other ideas. In a remarkably short half-hour period, a severe thunderstorm sprang up west of Ann Arbor, began spinning, and dropped a strong tornado down on the unfortunate town of Dexter, Michigan. The tornado skipped along a ten-mile path, damaging or destroying 128 buildings, but fortunately not causing any deaths or injuries. While most of the damage was light to moderate, thirteen homes were demolished, and preliminary damage estimates from the National Weather Service put the twister at the boundary between EF-2 and EF-3 strength, with winds of 135 mph. If confirmed as an EF-3, this would be the earliest EF-3 or stronger tornado in Michigan history, going back to 1950, according to data from The Tornado History Project. The previous earliest appearance of an F-3 tornado in Michigan was on March 20, 1976. At least two other tornadoes touched down in Michigan yesterday, making it the second largest tornado outbreak in state history so early in the year. The record outbreak for so early in the year was the eight tornadoes that touched down on March 12, 1976.

Video 2. This video report by AnnArbor.com's Nathan Bomey shows tornado damage in the Dexter, Michigan, about 90 minutes after the tornado came through on Thursday, March 15, 2012.

I talked to a friend in Dexter who relayed the story of her friend who was driving through town, saw the tornado, and pulled over into the Dexter car wash to take shelter. Some strangers living next door to the car wash yelled at him to come shelter in their basement, since the car wash didn't have a basement. He joined them, and was glad he did, because his car and the car wash were heavily damaged by a tree that was flung into it (see damage to the car wash in the video above.)

Hail, Hail, to Michigan
The Dexter storms also brought golfball to baseball-sized hail and a deluge of 4 - 5 inches of rain that caused street flooding in Ann Arbor. My Ph.D. advisor and co-founder of Weather Underground, Dr. Perry Samson, related this story to me: "I was traveling home by bus to go chase, but the bus came to a stand still at Michigan Stadium as cars were sunk up to their windows in water on Main Street. I told the driver I had to chase this storm, and came up with a story about what I do. He gunned the bus and drove through the flood to get me home. So I didn't actually commandeer a bus to chase the tornado, but it was darn close!"

Record Midwest March heat wave topples more records
For the second consecutive day, large portions of Illinois, Wisconsin, and Iowa, including the cities of Chicago, Madison, and Dubuque, recorded their all-time warmest temperatures for so early in the year. Perhaps the most extraordinary record occurred in Madison, Wisconsin, which hit 82°F--a temperature 39°F above average. It was the hottest temperature ever recorded in March, and three degrees warmer than any day so early in the year, going back to 1869. Not as many all-time hottest temperature records for so early in the year were set in Michigan and other surrounding states, due to plentiful moisture that generated afternoon cloud cover. The records will continue to fall across the Midwest for another week, as the ridge of high pressure responsible stays locked in place.

Major airports that set all-time heat records yesterday
For the second consecutive day, Chicago, Illinois hit 81°F; the warmest it's ever been this early in the year, going back to 1872, and 35°F above average. This ties the record set on March 12, 1990.

For the second consecutive day, Springfield, Illinois hit 83°F, the warmest it's ever been this early in the year, going back to 1879, and 32°F above average. This ties the record of 83°F on March 13, 1918.

Rockford, Illinois hit 82°F, the warmest it's ever been this early in the year, going back to 1893, and 36°F above average. Previous record: 79°F set the previous day.

Moline, Illinois hit 81°F, the warmest it's ever been this early in the year, going back to 1874, and 33°F above average. Previous record: 80°F on March 12, 1990.

Dubuque, Iowa hit 78°F, the warmest it's ever been this early in the year, going back to 1874, and 34°F above average. Previous record: 75°F set the previous day, and also on March 12, 1990.

Waterloo, Iowa hit 79°F, the warmest it's ever been this early in the year, going back to 1895, and 34°F above average. This ties the record set on March 7, 2000.

Madison, Wisconsin hit 82°F, the warmest it's ever been this early in the year, going back to 1869, and 39°F above average. This is also the warmest temperature ever recorded in March (tied with March 29th, 1986 and March 31, 1981), as is also (by two weeks) the earliest 80° reading ever measured there. The previous record for a temperature so hot this early in the year was 79°F set the previous day, on March 14, 2012.

Data for the previous records was taken from NOAA's National Climatic Data Center (NCDC).

I'll have a new post on Saturday.

Europe is still basking in record warmth, though the heat bubble seems to have shifted a bit east from where it's been over that past several days; parts of Hungary, Poland, the Czech Republic, Serbia, Belarus, and Slovakia (among others) are seeing record highs today. For instance, Krakow, Poland, is currently 72 (the average high for the date is 52), while Banja Luka, B&H, is 77, on a date when the average high is 59.

Apart from the warm GOM,those GulfStream waters off the East Coast are also very warm.

ty for the info, found this interesting weather tidbit: The only known instance of a tropical storm forming in February happened on Groundhog's day, February 2, 1952. A tropical storm actually made landfall in southwestern Florida. It was dubbed the "Groundhog's Day" tropical storm, because naming of hurricanes did not begin for the U.S. until 1953.

Good morning all. The blog seems to be a little messed up. I love the wildflowers in Australia - what a nice way to start the day, looking at all that beauty. Especially since it appears these grow out of rocky, sandy soil. The desert putting on a show now and then to let us know it isn't what we think it is.

So sorry for those folks in the path of Lua. Looks like a very big wind for them and lots of water.

Brisbane Tropical Cyclone Warning Center
Tropical Cyclone Advice #4
TROPICAL LOW 17U
11:00 PM EST March 17 2012
================================

At 10:00 PM EST, Tropical Low (991 hPa) located at 16.8S 141.5E or 105 km north northeast of Normanton and 245 km east of Mornington Island has 10 minute sustained winds of 25 knots with gusts of 45 knots. The tropical low is reported as moving northwest at 1 knots.

Dvorak Intensity: T2.0/2.0/D0.5/24 HRS

The centre of the TROPICAL LOW is located over land on southwestern Cape York Peninsula. However, the low is expected to move westwards over southern Gulf of Carpentaria waters during Sunday, where it may develop into a tropical cyclone overnight on Sunday.

GALES are expected to develop up to 170 kilometres from the low centre, affecting coastal areas between NT/Qld border and Cape Keerweer overnight on Sunday. GALES may develop between Port McArthur, including Borroloola and NT/Qld border on Monday, if the cyclone maintains a westward track.

A separate Severe Weather Warning is current for Heavy Rainfall and Abnormally High Tides for parts of the Gulf Country and Peninsula districts.

People between NT/Qld border and Cape Keerweer should take precautions and listen to the next advice at 2 am EST [1:30 CST].
- Information is available from your local government
- For cyclone preparedness and safety advice, visit Queensland's Disaster
Management Services website (www.disaster.qld.gov.au)
- For emergency assistance call the Queensland State Emergency Service (SES) on 132 500 (for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage).

For people in the Northern Territory:
The Territory Controller advises communities under Watch that now is the time to put together your emergency kit, clear your yards and balconies, and commence home shelter preparations.

Tropical Cyclone Watches/Warnings
=================================

A Cyclone WARNING has been declared for coastal and island communities from NT/Qld Border to Cape Keerweer, including Mornington and Sweers Islands.

A Cyclone WATCH is current for coastal areas from Port McArthur to NT/Qld Border, including Borroloola.

Forecast and Intensity
========================

12 HRS: 16.4S 140.7E - 30 knots (Tropical Low)
24 HRS: 16.2S 140.1E - 35 knots (CAT 1)
48 HRS: 16.8S 138.8E - 40 knots (CAT 1)
72 HRS: 18.1S 138.7E -

Additional Information
======================

Dvorak analysis based on a curved band pattern with 0.3 degree wrap on log10 spiral, giving DT of 2.0, MET=1.5 and PT suggest 2.0. FT based DT and PT.

The low exists in a moderate shear environment with favorable upper divergence evident on the CIMMS satellite imagery. Favorable sea surface temperatures greater than 30 degrees also exist across the Gulf of Carpentaria.

The low is located overland on southwestern Cape York Peninsula. However, it is most likely to adopt a westerly track during Sunday as the low falls under the influence of a mid level ridge developing across central Australia, taking the center back over the waters of southern Gulf of Carpentaria.

Next tropical cyclone advice on Tropical Low 17U from Brisbane Tropical Cyclone Warning Center will be issued at 16:30 PM UTC..

I wonder whether they considered reducing the emission of gasses that are the problem, instead?

Very strange, the way people think......

Make you wonder what kind of energy they are proposing to use to vapourise the sea water which of course wont be sea water once its vapourised as the salt wont vapourise, unless they are proposing some extreme temperatures.
Once they have pumped the stuff into the atmosphere it will only fall back as rain and the end result will be more energy entering the environment from the work done! Madness.
NOTE. I found the link a bit later to the above. It seems they want to mist the skies with sea water.

Severe Tropical Cyclone Lua crosses WA coast




Reports of extensive damage are emerging from Western Australia's Pilbara region, as Severe Tropical Cyclone Lua continues to batter communities.

The cyclone crossed the coast north of Port Hedland as a category four system about 3pm AWST on Saturday.

Jim Cahill from the Fire and Emergency Services Authority (FESA) says the township of Port Hedland seems to have avoided any damage.

But he says it is a different situation in Pardoo, which was directly in Lua's path.

"The report from Pardoo Roadhouse is that they have some damage to the property. It seems to be extensive but they can't be sure because there's a lot of water in the area and it's getting pretty dark," he said.

FESA crews will fly to Pardoo tomorrow to assess the damage.

The cyclone is now a category three, still bringing ferocious winds and rain to communities in its track.

Steve Bunce is a ranger at Cape Keraudren, an area that was in the cyclone's firing line.

"The house... If I was in a boat I would say I was sinking, I'm taking water pretty badly, the winds are just horrendous outside," he said.

Further inland, Yarrie cattle station is set to feel the brunt of Lua.

Owner Lang Coppin says his property is right in the firing line, and expects some extreme weather.

"Oh she'll be galloping when she gets here, it wont be backed off too much. It'll be giving us a bit of a hiding, but you do what you can," he said.


The Bureau of Meteorology says Lua will move further inland and gradually weaken.

It says gales are occurring in coastal areas between Port Hedland and Cape Leveque and will extend further inland on Saturday, and possibly west to Whim Creek.

"Destructive winds to 150 kilometres per hour are possible to the east of Port Hedland to Bidyadanga and across the inland eastern Pilbara," a weather burear statement read.

"Very Destructive winds to 250 kilometres per hour are forecast near the cyclone centre near the coast with gusts to 180 kilometres per hour possible over the inland eastern Pilbara, including Marble Bar this evening."

As well as strong winds, Lua is also bringing heavy rain and a dangerous storm tide.

"Tides are likely to rise significantly above the normal high tide mark with damaging waves and very dangerous flooding," the bureau said.

Alerts

A red alert is currently in place for coastal communities between Bidyadanga to Port Hedland, including the towns of Port and South Hedland, Marble Bar, Nullagine, and communities at Yandeyarra and Warralong.

The alert also includes mining leases at Yarrie, Woodie Woodie, Nifty, Moly Mines, and Telfer.

Those on a red alert are effectively in lockdown and are being advised to remain in shelter or go to shelter immediately.

A yellow alert is currently in place for people in remaining communities between Broome to Bidyadanga and Port Hedland to Whim Creek, including the town of Broome, the town of Newman and the community at Jigalong.

Those people are advised to take action and get ready to shelter from a cyclone.



Evacuation

In a separate incident, authorities have begun evacuating residents from one of Western Australia's most remote Aboriginal communities, after rising floodwaters cut off all services.

A monsoon system, separate from Severe Tropical Cyclone Lua, has dumped large amounts of rain over the Kimberley region this past week.

The community of Kalumburu has lost its water, sewerage and power services.

Thirty-five adults and six babies are being airlifted to the closest town of Kununurra.

TROPICAL CYCLONE ADVICE NUMBER 32
Issued at 7:05 pm WST on Saturday 17 March 2012

A Cyclone WARNING is current for inland parts of the east Pilbara, including
Marble Bar, Nullagine, Newman and Jigalong, the eastern Gascoyne including
Meekatharra and the far northern Goldfields including Wiluna.

The Cyclone Warning for coastal areas between De Grey to Bidyadanga, and areas
near Telfer has been cancelled.

At 7:00 pm WST Severe Tropical Cyclone Lua, Category 3 was estimated to be
125 kilometres southeast of Pardoo
195 kilometres east southeast of Port Hedland

3:00 AM WST March 17 2012
===========================

At 2:00 AM WST, Severe Tropical Cyclone Lua, Category Four (940 hPa) located at 19.8S 120.0E or 45 km east northeast of Pardoo 150 km east northeast of Port Hedland has 10 minute sustained winds of 95 knots with gusts of 135 knots. The cyclone is reported as moving south southeast at 13 knots.

Hurricane Force Winds
===================

Storm Force Winds
=================
70 NM from the center in northeast quadrant
30 NM from the center in southeast quadrant
30 NM from the center in southwest quadrant
70 NM from the center in northwest quadrant

Gale Force Winds
=============
170 NM from the center in northeast quadrant
60 NM from the center in southeast quadrant
60 NM from the center in southwest quadrant
160 NM from the center in northwest quadrant

Dvorak Intensity: T5.0/5.5/D0.5/24 HRS

Severe Tropical Cyclone Lua has now crossed the east Pilbara coast just to the east of Pardoo Station and will move further inland and gradually weaken.

Gales are occurring in coastal areas between Port Hedland and Cape Leveque and will extend further inland during today, and possibly west to Whim Creek.

Destructive winds to 150 kilometres per hour are possible to the east of Port Hedland to Bidyadanga and across the inland eastern Pilbara. Very Destructive winds to 250 kilometres per hour are forecast near the cyclone centre near the coast with gusts to 180 kilometres per hour possible over the inland eastern Pilbara, including Marble Bar this evening.

As the cyclone moves further inland, gales should reach the eastern Gascoyne areas, adjacent Interior and far northern Goldfields on Sunday morning.

Heavy rainfall is expected in coastal and inland parts of the east Pilbara extending into the eastern Gascoyne, western Interior and northern Goldfields later today or on Sunday.

Residents of the east Pilbara and 80 Mile Beach area, east of but NOT including Port Hedland, are specifically warned of the very dangerous storm tide expected this afternoon. Tides are likely to rise significantly above the normal high tide mark with damaging waves and very dangerous flooding.

Heavy surf conditions are also expected along the west Kimberley coast.

FESA-State Emergency Service advises of the following community alerts:

RED ALERT: People in coastal communities between Bidyadanga to Port Hedland, including the towns of Port and South Hedland, Marble Bar, Nullagine, and Communities at Yandeyarra and Warralong, Mining leases at Yarrie, Woodie Woodie, Nifty, Moly Mines, and Telfer and all other adjacent Mining and Pastoral leases need to remain in shelter or go to shelter immediately.

YELLOW ALERT: People in remaining communities between Broome to Bidyadanga and Port Hedland to Whim Creek including the town of Broome, the Town of Newman and the Community at Jigalong, and all adjacent Communities, Pastoral stations and Mining leases need to take action and get ready to shelter from a cyclone.

ALL CLEAR WITH CAUTION
Dampier to Whim Creek, including the towns of Dampier, Karratha, Roebourne, Wickham, Point Sampson and adjacent Communities and Pastoral and Mining leases are advised that wind danger has passed.

Remaining communities between Broome and Cape Leveque and in the inland eastern Pilbara, east Gascoyne and western Interior should listen for the next advice.


Tropical Cyclone Watches/Warnings
=================================

A Cyclone WARNING is current for coastal areas from Cape Leveque to Whim Creek, including Port Hedland and Broome, as well as inland parts of the east Pilbara and far west Kimberley, including Telfer, Newman and Jigalong, the eastern Gascoyne including Meekatharra, the far northern Goldfields including Wiluna and the far western Interior.

The Cyclone WARNING from Dampier to Whim Creek has been cancelled.

Forecast and Intensity
===============

12 HRS: 22.9S 120.1E - 50 knots (CAT 2)
24 HRS: 26.3S 120.0E - 35knots (CAT 1)

Additional Information
=======================

Severe TC Lua is currently crossing the east Pilbara coast near Pardoo as shown on the Port Hedland radar.

Intensity is estimated at 95 knots [category 4] at the top of the Dvorak 5.5 range although DT is at 5.0 based on IR embedded center pattern [in white] and MET is now at 5.0 as well. The high intensity estimate is also influenced by Rowley Shoals observations earlier today: 938.8hPa at 1am and 75 knot mean winds at 3am. As these are hourly reports, stronger intensities are probable, hence the central pressure is estimated at 932hPa.

Lua has a very large wind field with storm force winds extending about 2 degrees in the northern sector augmented by the strong monsoonal flow. This is generating significant waves north and east of the system.

Lua will weaken as it moves on a general southerly track inland but could still be at cyclone intensity until Sunday afternoon. The system will still cause heavy rain and gusty conditions through parts of southern WA after it weakens below tropical cyclone intensity.

The next tropical cyclone bulletin on Severe Tropical Cyclone Lua from the Perth Tropical Cyclone Warning Center will be issued at 8:30 AM UTC..

Brisbane Tropical Cyclone Warning Center
Tropical Cyclone Advice #3
TROPICAL LOW 17U
5:00 PM EST March 17 2012
================================

At 4:00 PM EST, Tropical Low (991 hPa) located at 16.9S 141.6E or 255 km east of Mornington Island and 160 km south of Kowanyama has 10 minute sustained winds of 25 knots with gusts of 45 knots. The tropical low is reported as moving northeast at 1 knots.

Dvorak Intensity: T2.5/2.5/D/24 HRS

The low may develop into a tropical cyclone in the next 24 to 48 hours.

The centre of the TROPICAL LOW is located over land on southwestern Cape York Peninsula. However, the low is expected to move back to the west over southern Gulf of Carpentaria waters over the next day or two, and may develop into a tropical cyclone.

GALES are expected to develop out to 170 kilometres out from the centre and are possible between the Port McArthur in the NT and Cape Keerweer by Monday morning.

A separate Severe Weather Warning is current for Heavy Rainfall and Abnormally High Tides for parts of the Gulf Country and Peninsula districts.

People between the Port McArthur in the Northern Territory and Cape Keerweer Queensland should consider what action they will need to take if the cyclone threat increases.
- Information is available from your local government
- For cyclone preparedness and safety advice, visit Queensland's Disaster
Management Services website (www.disaster.qld.gov.au)
- For emergency assistance call the Queensland State Emergency Service (SES) on 132 500 (for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage).

For people in the Northern Territory: The Territory Controller advises communities under Watch that now is the time to put together your emergency kit, clear your yards and balconies, and commence home shelter preparations.

Tropical Cyclone Watches/Warnings
=================================

A Cyclone WATCH is current for a developing tropical low for coastal areas from Port McArthur to Cape Keerweer, including Mornington and Sweers Islands.

Forecast and Intensity
========================

12 HRS: 16.8S 141.4E - 30 knots (Tropical Low)
24 HRS: 16.6S 140.9E - 30 knots (Tropical Low)
48 HRS: 16.7S 139.9E - 40 knots (CAT 1)
72 HRS: 18.1S 139.3E - 30 knots (Tropical Low)

Additional Information
======================

Dvorak analysis based on a curved band pattern with 0.5 degree wrap on log10 spiral, giving DT of 2.5, MET and PT suggest 2.5. Final Dvorak based DT.

The low exists in a moderate shear environment with favorable upper divergence evident on the CIMMS satellite imagery. Favorable sea surface temperatures greater than 30 degrees also exist across the Gulf of Carpentaria.

The low is located over land on southwestern Cape York Peninsula. However, it is most likely to adopt a westerly track by Sunday as the low falls under the influence of a mid level ridge developing across central Australia, taking the center back over the waters of southern Gulf of Carpentaria. The low is expected to develop into a tropical cyclone by early Monday if this track change occurs.

Next tropical cyclone advice on Tropical Low 17U from Brisbane Tropical Cyclone Warning Center will be issued at 13:30 PM UTC..

Quoting aspectre:
497 AussieStorm "I am watching The Weather Channel Australia here, They mentioned the waters off the NW Western Australian coast was between 34C and 36C. I have since found out by doing my own investigations that that was incorrect."

Hadda do some checking&correcting myself. My contribution to the exchange now reads
437 AussieStorm "She went from a Cat 3 to a Cat 4 and will cross the coast as a Cat 4. The waters there are boiling hot. 34C-36c."
443 KoritheMan "36C? [Expletive]"
494 aspectre "And a TropicalCyclone well worth expletiving about. Its minimum pressure has gotta be
~56millibars for water to boil at 35degreesCelsius(95degreesFahrenheit)"

Just found KoritheMan's reaction to a reported 34C-36C SST to be a bit over-the-top.
(The only time I've heard it used that way on broadcast television was within an amateur video shot live as the second jet crashed into the TwinTowers}
Then thought to m'self, what would truly be worthy of that kind of over-the-topness? And came up with a TropicalCyclone that made water literally (rather than figuratively) boil at 35degreesCelsius.
Which would be a superultrahypercane with a minimum pressure of 56millibars.
I guess I could serve to be a little less vulgar sometimes.
