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.

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.

Southern California Snow (
gemd)
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.

Watch me get blamed for it again...
I killed the blog for awhile just asking a weather question. That's what I get for asking a Mid-Atlantic question...at least I can blame a lull on football, today anyway.
Nah, its the AFC playoff game that killed the blog, not you :0)
OMG, My Bad. Thanks for update.
Happy for T-Dude, TampaSpin, & other Indiana fans.
Sorry, folks, I got pulled away from the blog for a little while; seems to happening a bit these days...LOL
Orca, I'm glad you enjoyed yourself; how is SWMBO?
SWMBO is relaxed and happy, which is the same as saying I am.. we know how that works :)
She was relaxed enough to be fishing Barracuda... with one on the line...and a beer in her other hand... at 730 in the morning. Can you get more relaxed?

Outstanding! Well, give her LST and my best!
okay is this coincidence if europe is expecting another cold air blast and maybe the US almost at similar time periods?? What ya'll think about this?
Because the NAO is expected to be negative. Just not as extreme as the last arctic blast.
Ya i agree with ya skye, that it wont be that extreme but still can be messy if theres alot of moisture in play.. like sum models indicating..
what i mean by widespread.. i mean the snow wont be widespread..
dropped 10 degrees the last 2 hours.. hmm
but i guess mostly everyone is watchin sum football lol
When the first siberian train arrived the US we had this too in europe here (starting around the beginning of december). Since than it pretty stayed this way. The siberian cold retreated a little but it was still below zero in most (northerly) parts of germany here. There has been many problems with public transport and electric shortages, especialy east of germany in poland. Cannot tell about russia though. The cold is considered by most as a real winter in long times. Each EU country has it's own story with this heavy winter which extended last "train" down to northern parts of africa (they reported snow) or florida for example. Around the equator (north/south) we see a lot of floods worldwide(cali, israel, saudi arabia, spain, albania, vietnam). In other areas it's snow. I think you can nail this down to an increase in precipitation - exactly what climate scientsit predict.
Please give more info about this. Book? Author?
NASA projections of stratospheric ozone concentrations if chlorofluorocarbons had not been banned.
The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), nitrous oxide (N2O), hydroxyl (OH), atomic chlorine (Cl), and atomic bromine (Br). While there are natural sources for all of these species, the concentrations of chlorine and bromine have increased markedly in recent years due to the release of large quantities of manmade organohalogen compounds, especially chlorofluorocarbons (CFCs) and bromofluorocarbons.[3] These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 100,000 ozone molecules. The breakdown of ozone in the stratosphere results in the ozone molecules being unable to absorb ultraviolet radiation. Consequently, unabsorbed and dangerous ultraviolet-B radiation is able to reach the Earth’s surface.[citation needed] Ozone levels, over the northern hemisphere, have been dropping by 4% per decade. Over approximately 5% of the Earth's surface, around the north and south poles, much larger (but seasonal) declines have been seen; these are the ozone holes.
In 2009, nitrous oxide (N2O) was the largest ozone-depleting substance emitted through human activities.

Earth's growing nitrogen threat
It helps feed a hungry world, but it's worse than CO2.
While greening farms worldwide, much nitrogen washes into lakes, rivers, and the sea, causing rampant algae growth. More nitrogen billows from power-plant smokestacks, blowing in the wind until it settles as acid rain. Still other nitrogen gases remain in the atmosphere consuming the ozone layer. Nitrous oxide is nearly 300 times as potent as carbon dioxide – considered the leading cause of climate change – and the third most threatening greenhouse gas overall.

LOS ANGELES (AP) - Think the recent wild weather that hammered California was bad? Experts are imagining far worse.
As torrential rains pelted wildfire-stripped hillsides and flooded highways, a team of scientists hunkered down at the California Institute of Technology to work on a "Frankenstorm" scenario - a mother lode wintry blast that could potentially sock the Golden State.
The hypothetical but plausible storm would be similar to the 1861-1862 extreme floods that temporarily moved the state capital from Sacramento to San Francisco and forced the then-governor to attend his inauguration by rowboat.
The scenario "is much larger than anything in living memory," said project manager Dale Cox with the U.S. Geological Survey.
In the scenario, the storm system forms in the Pacific and slams into the West Coast with hurricane-force winds, hitting Southern California the hardest. After more than a week of ferocious weather, the system stalls for a few days. Another storm brews offshore and this time pummels Northern California.
Such a monster storm could unleash as much as 8 feet of rain over three weeks in some areas, said research meteorologist Martin Ralph with the National Oceanic and Atmospheric Administration, who is part of the project.
It makes the latest Pacific storm system look like a drop in the bucket. A weeklong siege of storms walloped California, flooding coasts and roads, spawning tornados and forcing the evacuation of about 2,000 homes below fire-scarred mountains for fear of mudslides. The National Weather Service said the storms dumped up to a foot in the mountains northwest of Los Angeles in a week.
Weather experts say West Coast storms could get more frequent and severe with climate change. Last fall, a team of federal, state and academic experts was formed to tackle what would happen if a series of powerful storms lashed at the state for 23 days. The scenario is expected to be completed this summer and will be used in a statewide disaster drill next year.
Ironically, the team had scheduled meetings at Caltech to learn about the fictional storm's impact to dams, sewage treatment plants, transportation and the electrical grid. About a dozen canceled due to the storms.
