Summer in March, 2012, draws to a close

The most incredible spring heat wave in U.S. and Canadian recorded history is finally drawing to a close today, after a ten-day stretch of unprecedented record-smashing intensity. Since record keeping began in the late 1800s, there have never been so many spring temperature records broken, and by such a large margin. Airports in fifteen different states have set all-time records for March warmth, which is truly extraordinary considering that the records were set in the middle of the month, instead of the end of the month. The 29.2°C (85°F) measured at Western Head, Nova Scotia yesterday was the third warmest temperature ever recorded in Canada in March, according to Environment Canada and weather records researcher Maximiliano Herrera (top two records: 31.1°C at Alberini Beaver Creek BC on March 29th 1926, and 29.4°C in 1921 at Wallaceburg.) Michigan's all-time record for March warmth was toppled on Wednesday, when the mercury hit 90°F at Lapeer. The previous record, 89° at Lapeer in 1910, was matched at three stations yesterday--Ypsilanti, Dearborn, and Lapeer. The duration, areal size, and intensity of the Summer in March, 2012 heat wave are simply off-scale, and the event ranks as one of North America's most extraordinary weather events in recorded history. Such a historic event is difficult to summarize, and in today's post I will offer just a few of the most notable highlights.


Figure 1. Clear skies over the Eastern U.S. caused by a blocking ridge of high pressure on March 21, 2012, are apparent in this visible satellite image. The comma-shaped cloud pattern over the Central U.S. is associated with a "cut-off" low pressure system. This low is moving over the Eastern U.S. today through Saturday, and will bring an end to "Summer in March" over the U.S. and Canada.

Low temperatures beating previous high temperature records for the date
I've never seen a case where the low temperature for the date beat the previous record high. This happened on at least four occasions during "Summer in March, 2012":

The low temperature at Marquette, Michigan hit 52° on March 21, which was 3° warmer than the previous record high for the date.

The low at Mt. Washington, NH on March 21 (44°) beat the previous record high for the date (43°.)

The low temperature for International Falls, Minnesota on March 20 bottomed out at 60°F, tying the previous record high for the date.

The low temperature in Rochester, Minnesota on March 18 was 62°F, which beat the previous record high for the date of 60°.

Breaking all-time April records for warmth in March
Not only did many locations in Canada set records for their all-time warmest March day during "Summer in March, 2012", a number also broke their record for warmest April day:

St. John, New Brunswick hit 27.2°C (81°F) on March 21. Previous March record: 17.5°C on March 21, 1994. April record: 22.8°C.

Kejimkujik Park, Nova Scotia hit 27.9°C on March 21. Previous March record: 22.5°C on March 30, 1986. April record: 25°C on April 27, 1990.

Yesterday, I reported that Halifax, Nova Scotia hit 27.2°C (81°F) on March 22, 2012. Previous March record: 25.8° set the previous day. April record: 26.3°C, set on April 30, 2004. However, Rob Paola, a meteorologist with Environment Canada's Prairie and Arctic Storm Prediction Center in Winnipeg, Manitoba, wrote to tell me that Halifax did not break its April record: In fact, Halifax recorded a temperature of 29.5°C on April 28, 2009. For some reason, that stat does not show up on EC's normal/extremes climate site for Halifax, which only has data up to 2006 for extremes. More details on my blog at http://robsobsblog.blogspot.ca/

Breaking daily temperature records by more than 30°F
It is exceptionally rare for a weather station with a 50+ year period of record to break a daily temperature record by more than 10°F. During "Summer in March, 2012", beating daily records by 10° - 20°F was commonplace, and many records were smashed by over 20°. Two stations broke records by more than 30°F, which is truly surreal. Western Head, Nova Scotia hit 29.2°C (85°F), yesterday, breaking their previous record for the date (10.6°C in 1969) by 18.6°C (33°F.) Yesterday's high temperature was 24°C (44°F) above average. Pellston, Michigan in the Northern Lower Peninsula--dubbed "Michigan's Icebox", since it frequently records the coldest temperatures in the state--hit 85° on March 21. This broke the previous record for the date (53° in 2007) by 32°, and was an absurd 48°F above average.

Breaking daily temperature records nine consecutive days or more
It is extremely rare for stations with a 50+ year period of record to break a daily high temperature record for seven or more days in a row. The longest such streak of consecutive high temperature records at International Falls, Minnesota, was a 5-day period March 3 - 7, 2000. The city has tied or broken their high temperature for the date ten consecutive days, as of yesterday. This streak will likely end today, as the high is predicted to be 60 - 65, and the record high for the date is 66. Chicago, Illinois has tied or broken their daily high temperature record the past nine days in a row. This ties the nine-day streak of record highs set on August 26 - September 3, 1953. Other cites that have set daily high temperature records the past nine days in a row include Fort Wayne and South Bend, Indiana. Numerous cities have broken high temperature records on seven consecutive days during "Summer in March, 2012", including Gaylord, Pellston, and Traverse City in Michigan.

The big picture: the impacts of "Summer in March, 2012"
I've always said living in Michigan would be much more bearable if we could just get rid of March. March weather here is always horrible, with brutal cold, high winds, damaging ice storms, heavy snow, interminable cloudy stretches with no sun, all interspersed with a few teasing warm spells. Well, this year, I got my wish. This March, we started with twelve days of April weather, followed by ten days of June and July weather, with nine days of May weather predicted to round out the month. This has been a huge benefit to the economy--vastly reduced heating costs, no snow removal bills, and far fewer traffic accidents due to icy roads. However, there is major downside to the "Summer in March, 2012" heat wave. The growing season is now in full swing, five weeks early. A damaging freeze that will severely impact the fruit industry and other sensitive plants is very likely. Indeed, the forecast calls for lows in the upper 20s in the cherry-growing region of Michigan near Traverse City on Monday night. The exceptional March warmth has also melted all the snow in the northern U.S. and southern Canada, drying out the soils and setting the stage for a much warmer than average summer, and an increased chance of damaging drought conditions. The early loss of snowpack will also likely cause very low flow rates in the major rivers in late summer and early fall, reducing the amount of water needed for irrigation of crops. Low flows may also cause problems for navigation, limiting commercial barge traffic on Midwest rivers.

Wunderground's weather historian Christopher C. Burt will be posting a more comprehensive summary of the "Summer in March, 2012" heat wave this weekend.

Have a great weekend, everyone, and I'll be back Monday with a new post. I expect I'll be hard at work this weekend, mowing my lawn for the first time ever in March!

I would like to bring everyones attention to a petition that requests, "At least double NASA’s annual budget to one penny for every government dollar spent." NASA and other space programs are the future of humanity and needs to be funded . I think its only fair to ask if my generation and ones of the future are able to expirence something as amazing and inspiring as the Apollo program. Please take the time to sign the petition and thank you.

BAYAMON...CANOVANAS...CEIBA...GUAYNABO...SAN JUAN...TRUJILLO
ALTO...FAJARDO...CAROLINA...LUQUILLO AND RIO GRANDE

* UNTIL 830 PM AST

* AT 627 PM AST...DOPPLER RADAR DETECTED PERSISTENT RAIN IN THE
ADVISORY AREA. MOST OF THE HEAVY RAIN IS OCCURRING OVER THE SOUTHERN
PORTIONS OF THESE MUNICIPALITIES. SOME AREAS HAVE ALREADY RECEIVED
BETWEEN HALF-INCH AND ONE INCH OF RAIN...AND AT LEAST ONE MORE INCH
OF RAIN IS POSSIBLE WITH THESE SHOWERS THROUGH 830 PM AST. THIS WILL
RESULT IN MINOR FLOODING OF URBAN AND POOR DRAINAGE AREAS AS WELL
AS SOME OF THE STREETS AND ROADWAYS IN THE ADVISORY AREA.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. WHEN ENCOUNTERING FLOODED ROADS MAKE THE SMART CHOICE...TURN
AROUND...DONT DROWN.

An extract from:-655. BobWallace

"Yes, but the particulates could fall out as quickly as normal volcanoes. Cooling might be limited to only a few years, not long enough to bring about longer term changes."

You have a lot of possibilities with this one.
If the eruption is of a very large scale then even though most of the particles will have fallen back to earth in maybe 10 years, the effects of the volcanic eruption may have written off a large percentage of the humans, plus a lot of other life forms as well.
The added amount of greenhouse gases will initially add to the ones allready present but the total will tend to decline as the humans wont be producing many as a lot of them will have expired.
A state of balance may be possibly achieved with the hypothetical eruption as the reduced human activity may then just about maintain a balance of CO2,as the gases will be absorbed at about the same rate as they are produced.

In conclusion, I can only say that although a potential catastrophic eruption may initially be a bad thing (from the humans point of view,) in the long run it might solve the greenhouse gas problem.

Yes, but the particulates could fall out as quickly as normal volcanoes. Cooling might be limited to only a few years, not long enough to bring about longer term changes.

The current 'volcanoes triggered the Little Ice Age' thinking is that it was a series of volcanoes spread over some years and largely located close to the equator.



The cause appears to have been massive tropical volcanic eruptions, which spewed tiny particles called aerosols into the atmosphere. While suspended in the air, the aerosols reflect solar radiation back into space, cooling the planet below.

The cooling was sustained after the aerosols had left the atmosphere by a sea-ice feedback in the North Atlantic Ocean, the researchers believe. Expanding sea ice would have melted into the North Atlantic Ocean, interfering with the normal mixing between surface and deeper waters. This meant the water flowing back to the Arctic was colder, helping to sustain large areas of sea ice, which, in turn, reflect sunlight back into the atmosphere. The result was a self-sustaining feedback loop.

It seems that volcanoes close to the equator have a much larger effect on global temperatures than more polar eruptions - which would be expected.

The huge difference between a volcano and fossil fuel burning is (1) we don't have a choice and (2) we do. People need to be responsible citizens and quit worrying so much about their status quo oil money.

I'm not disputing the fact that global warming is occuring...I'm just saying that the chance of getting an Ice age would be more dependent on a catastophic event such as the eruption of a super volcano

Super volcanoes are more likely to cause major cooling as the volume of super volcanoes are many times that of the average volcanoes...the amount of ash emitted by these volcanoes is enough to blanket largeamount of earth's...the thick blanket off ash would reduce the amount of heat reaching the surfaceLink
