Deep freeze in the South continues

The Deep South shivered through a ridiculously frigid weekend, with low temperature records crumbling over much of Florida, Texas, and Louisiana. This morning, record lows for the date fell in Miami, West Palm Beach, Tampa, Fort Myers, Lakeland, Tallahassee, and St. Petersburg. The most extreme low temperature record this morning was set in Key West, where the mercury fell to 42°F at 5am--the second coldest temperature ever observed in Key West. This is just 1° warmer than the all-time coldest temperature observed in Key West--41° in January of 1981 and 1873. Widespread reports of sleet and snow flurries accompanied the cold blast across Central Florida on Saturday, the eighth snow event in Florida since 2000, according to Wikipedia. It remains to be seen how much damage the $9.3 billion Florida citrus industry will see because of the cold blast, which is the most severe in Florida since the December 1989 cold wave that devastated the citrus industry. Temperatures below the 28° that causes fruit damage affected some citrus-growing areas again this morning, for the third consecutive morning.

Intense and long-lasting cold
In Texas, two airports tied all-time January low temperature records on Saturday morning--Hondo, who's 12°F tied the record set January 11, 1982, and Cotulla La Salle, which hit 16°F, tying the record set January 13, 1975. Most of Texas' airports set daily low temperature records on Saturday morning. Saturday's low in Waco of 8°F broke the previous record of 15° for the date, and was the first time Waco has been in the single digits since the -4°F reading on December 23, 1989. Not only has the South's cold been intense, it has been exceptionally long-lasting. Montgomery, Alabama has had a low temperature below 25° nine consecutive days, breaking the old mark of seven straight days set in January 2001. With the cold snap only grudgingly scheduled to release its grip on the South, Montgomery can expect to run their streak of sub-25° lows to at least eleven straight days this week. Mobile, Alabama and Pensacola, Florida now have their second longest streak of days with a minimum temperature below freezing, at nine and eight days, respectively. Pensacola may equal or top their record of eleven straight days (set in January 1940) later this week, but Mobile is unlikely to break their record of fifteen straight days (set in February 1940). Also of note is that Key West has seen five consecutive days with low temperatures below 50 degrees (January 7th - 11th). This is the second longest such streak recorded in Key West, one day short of the record six-day streak on December 1 - 6, 1876. Key West has a decent chance of tying that record on Tuesday morning, when the low should fall to 50 or below.

A nicer beach weekend in Antarctica than Central Florida
Saturday's high and low temperatures in Orlando and Daytona Beach, Florida were 40° and 30°F. Tampa's high and low were 42°F and 29°F. Under sunny skies and light winds less than 10 mph, Saturday's high and low temperature at San Martin Base, Antarctica were 44° and 34°F. Gray, cloudy skies with winds gusting to 16 - 21 mph greeted beach goers at the beaches near Daytona Beach and Tampa, so it was a much nicer day at the beach in the Antarctic Peninsula than in Central Florida on Saturday (the Florida Chamber of Commerce loves stats like that!) Nice beach weather in Antarctica continued through Sunday, with sunny San Martin, Antarctica (high 41°, low 35°) recording an average temperature warmer than most stations in Central Florida. In all fairness, it is summer in Antarctica, and the ocean temperatures in Florida were a bit warmer than in Antarctica.

A major pattern shift coming
As I noted in my previous post, a sharp kink in the jet stream and a strong negative phase of the North Atlantic Oscillation is responsible for this winter's cold blast over eastern North America and Europe. The ridge of high pressure that has been blocking the west-to-east motion of weather systems over the past ten days is weakening, though, and a major shift in the winter weather pattern is in store for the Northern Hemisphere by late this week. A more typical El Niño pattern will set up, with the jet stream diving southward over California, bringing a strong flow of moist, Pacific air to the West Coast. A strong low pressure system will also bring heavy rain to the Gulf Coast on Friday and Saturday. Temperatures will slowly moderate across Europe and the Midwest and Eastern U.S. this week as the pattern gradually shifts, and more ordinary winter weather can be expected in these regions by next weekend.


Figure 2. Departure of the surface temperature from average for the first eight days of 2010 shows much colder than average conditions were present over the Midwest and Southern U.S., much of Europe, and Central Asia. Much warmer than average temperatures were present over the Northwest U.S., Greenland, the Arctic, and Southern Asia. A sharp kink in the jet stream was responsible for the temperature anomaly pattern. Image credit: NOAA/ESRL.

This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and after touchdown. The camera was funded by NASA.

The almost four-hour-long operation of the camera is shown in less than five minutes. That's 40 times the actual speed up to landing and 100 times the actual speed thereafter.

The first part of the movie shows how Titan looked to the camera as it acquired more and more images during the probe's descent. Each image has a small field of view, and dozens of images were made into mosaics of the whole scene.

Here, I live by the beach, and have warm weather clothes...

But, 1 1/2 to 2 hours away are our local mountains, with tons of snow, so, I have cold weather clothes as well....

so, if by some freak of nature, it got super cold down by the beach, I'd be ok....


Good almost afternoon to you! I hope your enjoying this wonderful S California weather. A lil showery for parts of S CA on Tu/We, but lookie here, OMG, a weather pattern change for S CA. Have rowboats anybody.

National Situation Update: Monday, January 11, 2010
Homeland Security Threat Level: YELLOW (ELEVATED).
Significant National Weather

South
Hard freeze conditions across the South will subside by Tuesday. Very cold temperatures continued throughout the region overnight from the teens to the 20 - degree range. The Deep South and areas east of the Mississippi will continue to see below average temperatures through mid-week, with gradual warming by Friday. Light snow showers are possible through Kentucky, eastern Tennessee, western North Carolina, the mountains of northern Georgia and northwest South Carolina through Tuesday. Light rain or drizzle will fall later today and continue through Tuesday across portions of southern Texas as the winds blow in from the Gulf of Mexico.

Northeast
Another surge of cold air from Canada will produce light snow across the region, beginning in western New York, western Pennsylvania, West Virginia, and extreme western Maryland by the early afternoon. Snow will move slowly eastward, crossing the mountains during the early evening.
A few flurries or light snow showers will spread into the I-95 corridor from Boston to Washington during the late evening and overnight hours. Accumulations should remain under two inches in the mountains. Some lake-effect snow will arrive but will end by Tuesday morning.

Midwest
Light snow will fall through the eastern Ohio Valley and eastern Great Lakes before moving east tonight. A few lake-effect snow squalls will end by Tuesday with accumulations under two inches in most areas. Locations closer to the Great Lakes could see up to three or four inches of snow before the system moves out.

West
The next set of storms will impact the Northwest coast this evening as rain spreads into northwest Oregon and western Washington. Some freezing rain is expected in low lying pockets of the Washington Cascades into central Washington, and light rain and snow will move east of the mountains in northern Washington into tomorrow. Another system from the Gulf of Alaska will bring rain into northern and central California by Tuesday morning. Snow accumulation is expected in the northern Washington cascades and the highest elevations of the Sierra Nevada range of up to 12 inches from 3,000 to 4,000 feet and higher. (NOAA, National Weather Service and Various Media Sources)

Northeast Snowfall Impact Scale

In 2004, a new method of describing and ranking “high-impact Northeast snowstorms” (the Northeast Snowfall Impact Scale -- NESIS), was developed by meteorologist Paul Kocin and Dr. Louis Uccellini of the National Weather Service. The NESIS describes storms with large areas of accumulating snowfall of 10 or more inches, and uses population information along with meteorological measurements to determine potential economic and transportation impacts. There are five storm categories: Extreme (5), Crippling (4), Major (3), Significant (2), and Notable (1). The December 18-20, 2009 storm was ranked a Category 3, one of only five storms ranked at Category 3 in the last decade. Two storms have been ranked Category 5; the super storm of March 1993, and the blizzard of January 1996. (NOAA.gov)

No new activity (FEMA HQ)

Earthquake Activity

6.5M California Earthquake – Final Summary
A 6.5 Magnitude earthquake occurred at a depth of 10 miles off the Coast of California at 7:27 p.m. EST on Saturday, January 9, 2009. Eighteen aftershocks from 2.3M to 4.4M followed the initial quake.. Although there was moderate shaking, a tsunami was not generated. Minor damage was reported including damage to the main fire department in Eureka, CA which remains under an “enter with caution” warning. Initially 20,000 customers lost power after the quake, by Sunday afternoon 8,300 customers were left without power, full restoration is expected today. No shelters were utilized and no reports of fatalities or injuries were reported. Although there were no major network or telephone outages, there are reports of localized phone outages.

Humboldt County EOC and the California State Operations Center are activated. Local emergencies were declared in Humboldt County and the city of Eureka, CA. Cal EMA Coastal Region is also activated; a representative is deployed to the Humboldt County EOC. No requests for Federal assistance have been received. (FEMA Region IX)

I'd love to see snow for my birthday...2-3

I would typically see it about every third birthday in MO, but down here I sort of gave myself over the idea that I woudln't anymore...


The GFS 12Z run showed Arctic air building up in North Central and North East Canada at the day 16 timeframe. How much, if any of that comes into the CONUS, I'm not sure.

Thankfully, we will have milder TX weather, with at least 3 good sized storm systems moving close to the Southern Plains over the next 14-16 days.

I am guessing that the first 2 weeks of February will be chilly, but that's yet to be seen.

Quoting AussieStorm:

let me clarify the question. At what height will boiling water freeze when its poured out and the air temp is 32F(0C)?

I have a steam generator that when it is first turn on in the morning, the water boils within seconds.

The reason is that the cooling of the water overnight generates a relatively strong vacuum in the tank by morning. By pressing the gun part of the generator, the vacuum is released and the water stops boiling (making noises like it is boiling).

I also read that mountain climbers have a tough time getting the water hot enough to cook with at the higher altitudes. Even heard that at high enough altitudes, the water could not be raised over 150 F without a sealed container.
