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.

And why couldnt it have rained this morning? Lol... of course the morning we actually had the moisture in place for snow!
I was excited for the Floridians who got there snow/sleet/ice.

The zoo in Texas has the cage, a picture of the animal, and a description of its habitat.

...ANOMALOUSLY STRONG SOUTHERN STREAM SYSTEM NEAR THE GULF COAST
LATE THIS WEEK...

SYSTEMS MOVING THROUGH THE MAIN BELT OF THE WESTERLIES WILL BE
PROGRESSIVE AS THE POLAR VORTEX MOVES FROM FAR NORTHERN CANADA
TOWARDS THE NORTH POLE...ACTING TO SPEED UP THE WESTERLY FLOW IN
THE MID-LATITUDES OF THE NORTHERN HEMISPHERE. THE SPLIT-FLOW
REGIME SEEN SINCE AT LEAST NOVEMBER WILL CONTINUE...THOUGH WITH AN
INCREASINGLY ZONAL PACIFIC JET CUTTING THROUGH THE EASTERN PACIFIC
AND AIMING TOWARDS CALIFORNIA...SYSTEMS MOVING THROUGH THE
SOUTHERN STREAM SHOULD BE MORE POTENT. IN KEEPING WITH THE SPIRIT
OF WHAT IS EVOLVING INTO A MORE TYPICAL FLOW PATTERN DURING EL
NINO CLIMATE REGIMES...WILL FAVOR THE GUIDANCE THAT MAINTAINS
SEPARATION BETWEEN THE NORTHERN AND SOUTHERN STREAMS WITH A
PREFERENCE TOWARDS STRONGER SOUTHERN STREAM SYSTEMS...WHICH FAVORS
THE 00Z CANADIAN/00Z ECMWF/00Z ECMWF ENSEMBLE MEAN/00Z GEFS MEAN.
THE PRESSURES USED A SIMPLE BLEND OF THE 00Z CANADIAN AND 00Z
ECMWF THROUGH THE PERIOD...WHICH MAINTAINED REASONABLE CONTINUITY.
THE PROGRESSIVE NATURE OF THE WESTERLIES ENSURES LOW CONFIDENCE
IN THE PREDICTABILITY OF SMALLER DETAILS AND COULD LEAD TO SWINGS
IN THE DETERMINISTIC/MANUAL GUIDANCE FROM RUN-TO-RUN AND
DAY-TO-DAY MID TO LATE PERIOD...SIMILAR TO WHAT WE SAW DURING THE
LESS PREDICTABLE LATE OCTOBER/EARLY NOVEMBER 2009 TIME FRAME.

...WEST...
A SYSTEM CLIPPING THE PACIFIC NORTHWEST SHOULD BRING HEAVY
PRECIPITATION PRIMARILY TO BRITISH COLUMBIA/VANCOUVER ISLAND...BUT
ONLY A SMALL SHIFT TO THE SOUTHEAST WITH THIS SYSTEMS TRACK WOULD
BRING THE THREAT INTO WESTERN WASHINGTON STATE. THE POSITION OF A
POSITIVE ANOMALY CENTER WHICH IS POSITIVELY TILTED OVER ONTARIO
FAVORS A NEGATIVE TILTED TROUGH POINTED INTO CALIFORNIA...WHICH
SHOULD LEAD TO WETNESS ACROSS SECTIONS OF THE GOLDEN STATE THIS
WEEKEND INTO EARLY NEXT WEEK. DUE TO THE STRENGTH OF HIGH
PRESSURE IN ADVANCE OF THIS SYSTEM /AND THE WAKE OF THE GULF COAST
SYSTEM/ ITS SURFACE REFLECTION SHOULD BE LOST BY SUNDAY MORNING.


...GULF COAST/EAST...
A LARGE AND ANOMALOUSLY DEEP CYCLONE MOVING THROUGH SOUTH TEXAS
AND THE GULF OF MEXICO DAYS 3-5 SHOWS GOOD AGREEMENT ON TRACK AND
INTENSITY...INCLUDING THE LIKELIHOOD OF HEAVY RAIN ACROSS PORTIONS
OF EASTERN TEXAS THE CENTRAL GULF COAST STATES. STANDARDIZED
ANOMALIES ACROSS MEXICO IN BOTH THE 500 HPA HEIGHT PATTERN AND 850
HPA TEMPERATURE PATTERN ARE IMPRESSIVE...APPROACHING 6 AND 4
SIGMAS BELOW NORMAL RESPECTIVELY. THIS ATYPICALLY COLD AIR ALOFT
WILL INTERACT WITH THE NATURAL TEMPERATURE GRADING IN THE
NORTHWEST GULF OF MEXICO...AND SHOULD LEAD EXPLOSIVE CONVECTIVE
DEVELOPMENT WITHIN THE GULF OF MEXICO IN 4-5 DAYS TIME WHICH
SHOULD DEEPEN THE SURFACE LOW. IN SOME RESPECTS...THIS IS SIMILAR
TO THE FLOW PATTERN AROUND NOVEMBER 8-9 2009...BUT WITH STRONGER
DYNAMICS ALOFT AND NO TROPICAL CYCLONE INVOLVED. THE GFS IS A
FAST OUTLIER WITH THIS SYSTEM. SINCE ITS QUICK SOLUTION IS NOT
SUPPORTED BY THE 00Z MULTI-MODEL ENSEMBLE MEMBERS...DISCOUNTED ITS
SOLUTION. IF THE GUIDANCE IS SOMEHOW A LITTLE TOO WEAK WITH THIS
SYSTEM...MEASURABLE FROZEN PRECIPITATION WOULD BE POSSIBLE ACROSS
SOUTHERN/CENTRAL TEXAS AS 850 HPA TEMPERATURES ARE BARELY ABOVE
FREEZING WITHIN ITS EXPECTED COMMA HEAD. ONCE THE SYSTEM LIFTS
OUT ALONG THE GULF COAST/DEEPENS NEAR AND OFFSHORE THE EAST
COAST...PRECIPITATION COULD START AND END AS FROZEN ACROSS THE
MID-ATLANTIC/NEW ENGLAND STATES THIS WEEKEND INTO EARLY NEXT WEEK.
STAY TUNED.
