The most powerful low pressure system in 140 years of record keeping swept through the Southwest U.S. yesterday, bringing deadly flooding, tornadoes, hail, hurricane force winds, and blizzard conditions. We expect to get powerful winter storms affecting the Southwest U.S. during strong El Niño events, but yesterday's storm was truly epic in its size and intensity. The storm set all-time low pressure records over roughly 10 - 15% of the U.S.--over southern Oregon, and most of California, Nevada, Arizona, and Utah. Old records were broken by a wide margin in many locations, most notably in Los Angeles, where the old record of 29.25" set January 17, 1988, was shattered by .18" (6 mb). Bakersfield broke its record by .30" (10 mb). The record-setting low spawned an extremely intense cold front that rumbled thought the Southwest, and winds ahead of the cold front reached sustained speeds of hurricane force--74 mph--last night at Apache Junction, 40 miles east of Phoenix. Wind gusts as high as 94 mph were recorded in Ajo, Arizona, and a Personal Weather Station in Summerhaven (on top of Mt. Lemmon next to Tucson) recorded sustained winds of 67 mph, gusting to 86 mph, before the power failed. Prescott recorded sustained winds at 52 mph, gusting to 67 as the cold front passed, and high winds plunged visibility to zero in blowing dust on I-10 connecting Phoenix and Tucson. The storm spawned one possible tornado in Arizona, which touched down at 8:32 pm MST in Phoenix near Desert Ridge Mall. No damage or injuries were reported. If verified, it would be only the 7th January tornado in Arizona since record keeping began in 1950.

Some of the all-time low pressure records set in yesterday's storm:
Los Angeles, CA: 29.07", Old Record: 29.25", January 17, 1988
Eureka, CA: 28.90", Old Record: 28.91", February 1891
San Diego, CA: 29.15", Old Record, 29.37", March 3, 1983
Fresno, CA: 28.94", Old Record, 29.10", January 27, 1916
Bakersfield, CA: 28.94", Old Record, 29.24", February 3, 1998

Salt Lake City, UT: 28.94", Old Record, 29.00" April 2002

Reno, NV: 28.94", Old Record, 29.00", January 27, 1916
Las Vegas, NV: 29.03" Old Record: 29.17", December 1949

Phoenix, AZ: 29.22", Old Record: 29.32", May 18, 1902
Flagstaff, AZ: 29.13", Old Record: 29.15", February 7, 1937
Yuma, AZ: 29.15", Old Record: 29.37", September 12, 1927

Three tornadoes in California
Three tornadoes were reported in California yesterday. A small EF0 twister hit the east side of Ventura, leaving a 1.5 mile damage path. Another tornado hit Santa Barbara, downing trees and power poles. The most damaging California tornado yesterday touched down just west of Blythe, on the Arizona-California border, at 4:31 pm MST. The twister crossed I-10, blowing three semi trucks over, ripping the roofs off houses, and downing power lines. I-10 was closed for several hours to clear the debris and toppled trucks.

Two tornadoes also hit Southern California on Tuesday. A sheriff's deputy spotted a possible tornado in Goleta that caused some roof damage, and another tornado hit Huntington Beach, damaging boats and buildings and flipping cars.

If all five tornadoes are confirmed as genuine by the National Weather Service, it will tie the record of most January California tornadoes. The all-time record for most California tornadoes in a single day is seven, set on April 1, 1996, and November 9, 1982.


Figure 2. Radar reflectivity from the Los Angeles Doppler radar at the time of the Santa Barbara tornado.

Figure 3. Storm-relative radial velocity from the Los Angeles Doppler radar at the time of the Santa Barbara tornado. The area of yellow and orange colors, lying right next to a region of blues and greens just west of Santa Barbara shows that the winds in that region were moving towards and away from the radar in a very tight area, signifying the presence of a rotating thunderstorm and possible tornado.

The storm will continue to bring heavy rain and snow to many portions the Southwest today, then wind down on Saturday. A new storm is expected to move ashore over Northern California on Sunday night, but this storm will not be as intense. Another storm is also possible next Friday, January 29, but it appears that a renewed battering by a long succession of storms like we had this week will not occur next week.

Tornadoes, severe weather in the South
Severe weather associated with a separate storm brought damaging winds, hail, and tornadoes to portions of Kentucky, Tennessee, Georgia, Alabama, and Florida last night. Two tornadoes were reported, one in Tennessee, and one in Alabama, near Huntsville. The Huntsville tornado injured approximately six people, and cut power to 10,000 people. The storm responsible for the severe weather has moved out to sea, and no further severe weather is expected today. A slight chance of severe weather is expected Saturday over Arkansas and Mississippi, and there is also a severe weather threat for Georgia and surrounding states on Sunday.

Portlight's Paul Timmons to appear on NBC and CNN
Portlight.org, the disaster-relief charity that has sprung up from the hard work and dedication of many members of the wunderground.com community, has successfully shipped medical equipment and a water filtration unit capable of supplying the needs of 3,500 people per day to the Dominican Republic. The relief supplies were trucked to Haiti via road, and have made it to the earthquake zone. The supplies have been targeted to go to those with disabilities, or to those who are living in areas where the main aid efforts have been inadequate. Portlight is working through the local Catholic Church, which is probably best positioned to deliver private aid donations to those in need. Paul Timmons, leader of the Portlight relief efforts, is scheduled to appear on NBC news later today, and on CNN news tomorrow, to discuss Portlight's efforts.


Figure 5. Walkers and medical supplies for Haiti getting ready to ship from the Portlight warehouse in Atlanta.

Please visit the Portlight.org blog to learn more. Floodman's blog has the latest info on Portlight's plan for Haitian relief. The Reeve Foundation, founded by Christopher and Dana Reeve has awarded Portlight Strategies a $10,000 Quality of of Life grant to assist in the relief efforts in Haiti. This is very big and will allow Portlight to pursue more aggressive relief efforts over the course of the next few weeks.

For those of you more interested in helping out with the long-term rebuilding of Haiti's shattered infrastructure from the quake, I recommend a contribution to Lambi Fund of Haiti, a charity that is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level in Haiti. I've developed a great respect for the work they do in the country in the five years I've been a supporter.

A Pacific storm (usually warm) came and dropped snow in Southern California in area which rarely see snow. This was not even an "insider slider" (lingo for a northern, non-Pacific cold jet stream). Snow days for schools are rampant and there are many accidents on the roadways. Our snow is not the typical fluff, but very wet and slick.

Good morning, everybody! Weather is rather sullen here this morning, but temps are still warm - 81 degrees with a predicted high of 77 LOL - so I'm not complaining too much.

Looking at the OZ storm (Olga, right?) I notice they are now forecasting a chance of reintensification in the GoC.....

NWS NOLA discussion

Short term...
from previous discussion...
radiational sea fog continuing to form along the lower Mississippi
River and immediate MS coast. Will keep dense fog advisory for the
MS coast and lower la parishes as warm air advection continues
through the night. Advisory may need to be expanded north and west
later but for now it appears low level jet is providing enough
mixing to keep visibilities up. Should be clearing up not long after
sunrise.


Expecting another unseasonably warm January day across the Gulf
south. Should take a while for cloud cover to move in today and with
temperatures 15 degrees above normal yesterday...went on the warm side of
guidance with low to middle 70s across much of the area. Did keep
locations along the coast below 70 as southerly winds across the
relatively cool Gulf waters restrict surface warming.


Surface analysis shows cold front slowly moving across central Texas
with shower activity Post frontal. An associated warm front is
draped across East Texas through hou and into the central Gulf of
Mexico. A surface low will drop out of The Rockies and across the
middle to lower miss valley tonight. The warm front will lift north of
the County Warning Area later this evening with the cold front reaching the western
half of the County Warning Area between 00z and 06z. Most of the heavier rain should
remain north of the area. Not very impressed with instability in
terms of storm strength but will likely be enough for few
thunderstorms and maybe some sub-severe. Did undercut mav guidance
for western areas as it looks like the better lift will occur as the
front reaches east of I-55.


Showers will persist in the southeastern half of the area through Sunday as
the cold front slows due to the upper trough digging a little
farther south and flattens. Should be rain free across the County Warning Area by
Sunday night.


Long term...
colder and drier air will filter into the region behind this front
and high pressure will build in. High temperatures through middle week
will be much closer to normal. A light freeze will be possible
Tuesday and Wednesday morning as light winds and clear skies allow
for good radiational cooling. Temperatures will moderate a little late this
week ahead the next system that will impact the area. There/S still
a problem with consensus between models in terms of timing but
expecting rain between Friday and Saturday. A few thunderstorms will
be possible but not looking severe at this time.

Hey buddy, I think we maybe back at it again tracking severe wx moving across C FL Sunday night and early Monday. What do you think?


It's all about timing looks like the shear and dew points will be high enough for some severe weather, but will the atmosphere be unstable enough? (specifically, the temperature lapse rate) Your guess is as good as mine.

Chronic CO2 Toxicity: Species Difference in Physiological and Histopathological Effects
Abstract: Guinea pigs were found to have a much higher susceptibility to carbon dioxide than rats. During exposure to CO2 concentrations ranging from 1-50% CO2, marked species differences were observed in mortality, growth curves, organ/body weight ratios and serum enzyme responses. The difference in tolerance to CO2 between guinea pigs and rats has been related to their differing buffer capacity. Guinea pigs showed higher levels of hydrogen ion concentrations for every exposure. No evidence of tissue necrosis in heart, liver, and other organs was obtained in guinea pigs or rats exposed for prolonged periods to 15% CO2. The increased levels of serum enzymes (GPT, GOT, LDH) observed in guinea pigs under these conditions were interpreted as signs of increased permeability caused by hypercapnia. An organ specific pattern of fat accumulation was observed in chronic hypercapnia.

Here's the problem I have with considering C02 a pollutant. I'll agree that in higher concentrations it is toxic. But the amount our atmosphere contains is harmless. That's why it's considered a trace gas. It's not the nature of the gas that is the problem. It's the concentration. If you take 100% pure oxygen and breath it in for an extended period of time your lungs begin to fill with fluid and damage begins occurring to lung tissue. You could consider it toxic, but we don't go classifying it as a pollutant.


The GW people might.....LOL

Good morning everyone. Locals got a nice day on tap. Nice after yesterday. That brought me .47inch & a 12mph gust.

NWS in Melbourne has got their tornado & storm damage report together. I'll post the path but their report is worth a visit..great radar saves, lots of damage photos, even road cam with a trailer on it's side. Too close to Brevard Zoo..


Favorite buoy report..

Ask Aussie how comfortable Sydney was yesterday before the front swept thru,..108F I believe.

But as some will say,..a Local specific region dosent drive home a warming debate,..

But I can say this..Down Under has been a tad warm the past two Summers,and I dont think anyone would disagree there.


This summer has been warmer than any summer i have experienced. 108.1F here on Saturday till 15:30 then the front came through and the temp went down to 71F

“A slightly shocking finding,” Tripati said, “is that the only time in the last 20 million years that we find evidence for carbon dioxide levels similar to the modern level of 387 parts per million was 15 to 20 million years ago, when the planet was dramatically different.”

Levels of carbon dioxide have varied only between 180 and 300 parts per million over the last 800,000 years — until recent decades, said Tripati, who is also a member of UCLA’s Institute of Geophysics and Planetary Physics. It has been known that modern-day levels of carbon dioxide are unprecedented over the last 800,000 years, but the finding that modern levels have not been reached in the last 15 million years is new.

Prior to the Industrial Revolution of the late 19th and early 20th centuries, the carbon dioxide level was about 280 parts per million, Tripati said. That figure had changed very little over the previous 1,000 years. But since the Industrial Revolution, the carbon dioxide level has been rising and is likely to soar unless action is taken to reverse the trend, Tripati said.

“During the Middle Miocene (the time period approximately 14 to 20 million years ago), carbon dioxide levels were sustained at about 400 parts per million, which is about where we are today,” Tripati said. “Globally, temperatures were 5 to 10 degrees Fahrenheit warmer, a huge amount.”

Quoting SouthDadeFish:
481, CO2 levels have not remained at 280 ppm for the past 15 million years, it fluctuated. And I am pretty sure CO2 levels will not make up 8% of the atmosphere.

Science: CO2 levels haven’t been this high for 15 million years, when it was 5° to 10°F warmer and seas were 75 to 120 feet higher — “We have shown that this dramatic rise in sea level is associated with an increase in CO2 levels of about 100 ppm.”
October 18, 2009

You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science.

“The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland,” said the paper’s lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

“Carbon dioxide is a potent greenhouse gas, and geological observations that we now have for the last 20 million years lend strong support to the idea that carbon dioxide is an important agent for driving climate change throughout Earth’s history,” she said.

Yes, pumping more and more CO2 into the air is a very bad idea, as this news release from UCLA on a major new study makes clear. The study itself, “Coupling of CO2 and Ice Sheet Stability Over Major Climate Transitions of the Last 20 Million Years,” (subs. req’d) was released by Science earlier this month.

The study notes importantly, “This work may support a relatively high climate sensitivity to pCO2” [the partial pressure of CO2], which is the same conclusion that a number of major studies looking at paleoclimate data have come to:

Scientists analyzed data from a major expedition to retrieve deep marine sediments beneath the Arctic to understand the Paleocene Eocene thermal maximum, a brief period some 55 million years ago of “widespread, extreme climatic warming that was associated with massive atmospheric greenhouse gas input.” This 2006 study, published in Nature (subs. req’d), found Artic temperatures almost beyond imagination–above 23°C (74°F)–temperatures more than 18°F warmer than current climate models had predicted when applied to this period. The three dozen authors conclude that existing climate models are missing crucial feedbacks that can significantly amplify polar warming.

A second study, published in Geophysical Research Letters (subs. req’d), looked at temperature and atmospheric changes during the Middle Ages. This 2006 study found that the effect of amplifying feedbacks in the climate system–where global warming boosts atmospheric CO2 levels–”will promote warming by an extra 15 percent to 78 percent on a century-scale” compared to typical estimates by the U.N.’s Intergovernmental Panel on Climate Change. The study notes these results may even be “conservative” because they ignore other greenhouse gases such as methane, whose levels will likely be boosted as temperatures warm.

The third study, published in Geophysical Research Letters (subs. req’d), looked at temperature and atmospheric changes during the past 400,000 years. This study found evidence for significant increases in both CO2 and methane (CH4) levels as temperatures rise. The conclusion: If our current climate models correctly accounted for such “missing feedbacks,” then “we would be predicting a significantly greater increase in global warming than is currently forecast over the next century and beyond”–as much as 1.5°C warmer this century alone.

So we need to keep atmospheric concentrations of CO2 as low as possible — and if we do go above 450 ppm, we need to get back to under 350 ppm as rapidly as possible, preferably by century’s end, though that would be no easy feat.
