Info RER Record Breaking Event Report — Sat Feb 17, 2007 9:14 AM

RERTLH) OUR COOP SITE IN GENEVA ALSO REACHED 18 DEGREES
WITH 19 DEGREES MEASURED AT CUTHBERT GA. IT APPEARS FROM
OBSERVATIONS THAT SOME LOCATIONS ACROSS THE REGION EXPERIENCED
DURATIONS OF FREEZING TEMPERATURES FOR 10 TO 12 HOURS WITH HARD
FREEZING CONDITIONS AWAY FROM THE IMMEDIATE COAST LASTING FOR 4
TO 6 HOURS...THUS VERIFYING THE HARD FREEZE WARNING.

TEMPERATURES ARE NOW BEGINNING TO WARM ACROSS THE REGION UNDER SUNNY
SKIES...BUT STILL HANGING ON TO SOME SUB FREEZING TEMPERATURES IN
THE NORMALLY COLDEST LOCATIONS. THE 13 UTC SURFACE ANALYSIS IS
SHOWING A WELL DEFINED CLIPPER SYSTEM DIGGING INTO THE TENNESSEE
RIVER VALLEY WITH ASSOCIATED COLD FRONT DROPPING INTO CENTRAL
MISSISSIPPI AND NORTH CENTRAL ALABAMA. A 1024 MB SURFACE HIGH IS
LOCATED ABOUT 150 MILES SOUTH OF APALACHICOLA. ANOTHER INTERESTING
FEATURE OF NOTE IS ON THE MORNING UPPER AIR SOUNDING HERE AT KTAE
WHERE THE PRECIPITABLE WATER DROPPED TO 0.09 INCHES.

AS THE COLD FRONT APPROACHES THE REGION TODAY...EXPECT WINDS TO
INCREASE OUT OF THE SOUTHWEST AND BECOME GUSTY AT TIMES. THIS WILL
ALSO HELP TEMPERATURES REBOUND SIGNIFICANTLY INTO THE MID TO UPPER
50S ACROSS THE REGION. CLOUD COVER WILL INCREASE IN THE
AFTERNOON...BUT IS EXPECTED TO REMAIN ONLY PARTLY CLOUDY UNTIL
EVENING WHEN MOSTLY CLOUDY SKIES MAY OCCUR. ALL THIS IS HANDLED WELL
IN THE CURRENT FORECAST...SO NO CHANGES ANTICIPATED AT THIS TIME.

&&

.AVIATION...SOUTHWEST WINDS WILL BEGIN TO PICK UP LATER THIS MORNING
AND BECOMING GUSTY THIS AFTERNOON AS THE COLD FRONT APPROACHES. ONCE
THE COLD FRONT GETS A LITTLE CLOSER THIS AFTERNOON...SOME LOW END
VFR CIGS AROUND 5KFT WILL BE POSSIBLE AT SOME OF THE TERMINALS. NO
RESTRICTIONS ARE EXPECTED.

&&

.MARINE...OBSERVATIONS FROM THE BUOYS HAVE DROPPED OUT DUE TO COMMS
PROBLEMS...BUT WITH HIGH PRESSURE OVER THE WATERS WINDS AND SEAS ARE
LIKELY REMAINING LOW. ADDITIONALLY...COASTAL ASOS SITES ARE SHOWING
LIGHT SOUTHERLY WINDS. WINDS AND SEAS THOUGH WILL INCREASE AND BUILD
THROUGH THE AFTERNOON HOURS AS THE PRESSURE GRADIENT BEGINS TO
TIGHTEN. PREVIOUS FORECAST LOOKS GOOD AND NO CHANGES ARE PLANNED.

&&

.FIRE WEATHER...FOR TODAY...AN HOUR OF 20-FT WIND 15 MPH OR GREATER
AND LOW RH CRITERIA SHOULD BE MET IN FL. FOR GA...NEED AN HOUR OF
SUSTAINED WIND OF 20 MPH OR GREATER AND/OR FREQUENT GUSTS ABOVE 25.

WILL LIKELY BE UPGRADED TO WARNINGS THIS AFTN.
