Area forecast discussion, Apr 16, 3:52 AM EDT, 2 hours 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
352 AM EDT SAT APR 16 2011

...A TORNADO WATCH IS IN EFFECT UNTIL 10 AM EDT FOR MOST OF THE
ENTIRE FORECAST AREA EXCLUDING LAFAYETTE AND DIXIE COUNTIES...

.SHORT TERM (TODAY THROUGH MONDAY)...THE MAIN CONCERN FOR THE SHORT
TERM PERIOD WILL BE THE POSSIBILITY FOR LINGERING SEVERE WEATHER AS
THE COLD FRONT PUSHES EAST OUT OF OUR LOCAL AREA THIS MORNING. LOW
LEVEL WIND SHEAR AND HODOGRAPHS SUPPORT THE THREAT FOR TORNADOES
THROUGH THE EARLY MORNING HOURS. THIS THREAT IS FURTHER AIDED BY
FAVORABLE INSTABILITY RESULTING FROM THE NORTHWARD SURGE OF HIGHER
DEWPOINT OFF THE GULF. WEAKER LOW LEVEL SHEAR AND SLIGHTLY LESS
FAVORABLE HODOGRAPHS WILL REDUCE THE TORNADO THREAT OVER NORTH
FLORIDA...HOWEVER...AN ISOLATED TORNADO THREAT STILL EXISTS.
ALSO...DAMAGING WINDS AND SMALL HAIL CAN BE EXPECTED WITH ANY SEVERE
STORMS THAT DO FORM. BY SUNRISE...THE LINE OF STORMS IS EXPECTED
TO BE OVER OUR EXTREME EASTERN COUNTIES PRIMARILY AFFECTING SOUTH
CENTRAL GEORGIA AND THE EASTERN BIG BEND OF FLORIDA. LOW LEVEL SHEAR
IS EXPECTED TO REMAIN FAVORABLE IN THE DAWN HOURS AND AN ISOLATED
TORNADO THREAT CANNOT BE RULED OUT ESPECIALLY OVER SOUTH CENTRAL
GEORGIA. THAT BEING SAID...THE PRIMARY THREAT AS THESE STORMS EXIT
THE REGION THROUGH THE LATE MORNING WILL BE DAMAGING WINDS AND SMALL
HAIL.

AS THE LARGE UPPER LOW RESPONSIBLE FOR THE SEVERE WEATHER OPENS UP
AND RACES NORTHEAST...ZONAL FLOW WILL OVERSPREAD THE LOCAL AREA AND
HEIGHTS WILL GRADUALLY RISE. HIGHS THIS AFTERNOON WILL CLIMB TO THE
UPPER 70S TO LOWER 80S REGIONWIDE. WITH THE INFLUX OF DRY
AIR...OVERNIGHT LOWS TONIGHT WILL FALL INTO THE UPPER 40S (SLIGHTLY
BELOW AVERAGE). WITH THE FLOW EXPECTED TO REMAIN ZONAL...AND DRY AIR
REMAINING IN PLACE...SUNDAY WILL BE MUCH LIKE TODAY WITH HIGHS IN
THE LOWER 80S AND LOWS IN THE UPPER 40S. ON MONDAY...HEIGHTS WILL
INCREASE SLIGHTLY RESULTING IN HIGH TEMPERATURES CLIMBING INTO THE
MID 80S.

AFTER THIS MORNING...NO RAIN IS EXPECTED DURING THE SHORT TERM
PERIOD.

.LONG TERM (MONDAY NIGHT THROUGH NEXT SATURDAY)...AN UPPER LEVEL
RIDGE WILL BEGIN TO BUILD OVER THE LOCAL AREA MONDAY NIGHT AND
SHARPEN AS IT MOVES EAST OFF THE EASTERN SEABOARD THROUGH WEDNESDAY
BEFORE FLATTENING WEDNESDAY NIGHT. THE EAST TO WEST SURFACE RIDGE
ALSO WEAKENS AND ALLOWS A COLD FRONT TO DROP SOUTH INTO CENTRAL
GEORGIA AND ALABAMA BY DAYBREAK THURSDAY. THIS BOUNDARY WILL THEN
LIFT TO THE NORTH AS A WARM FRONT LATER THURSDAY THROUGH FRIDAY AS
ANOTHER LOW PRESSURE SYSTEM DEVELOPS IN THE CENTRAL PLAINS AND
TRANSLATES TO NORTHERN ILLINOIS FRIDAY EVENING. THIS LOW THEN MOVES
JUST NORTH OR THROUGH NEW ENGLAND SATURDAY WITH IT'S ATTENDANT COLD
FRONT DROPPING DOWN FROM THE NORTH INTO OUR CWA LATE SATURDAY. DUE
TO THE PROXIMITY OF BOTH MENTIONED FRONTS WILL SHOW JUST SLIGHT POPS
FOR ALL ZONES NORTH OF THE FLORIDA BORDER FOR THE WEDNESDAY
NIGHT/THURSDAY AND SATURDAY TIME FRAMES. OTHERWISE...IT SHOULD BE
DRY FOR THE REMAINDER OF THE EXTENDED PERIOD. TEMPERATURES WILL BE
ABOVE SEASONAL LEVELS THROUGH THE PERIOD WITH MAX TEMPS RANGING FROM
THE MID 80S TO AROUND 90 FOR ALL BUT THE FLORIDA COASTAL AREAS EACH
DAY.

&&

.AVIATION...CONVECTIVE ACTIVITY AHEAD OF A COLD FRONT WILL MOVE FROM
WEST TO EAST ACROSS THE TRI-STATE REGION THIS MORNING. ALL ACTIVITY
SHOULD BE EAST OF VLD BY 16Z. AFTER THE FRONT PASSES EACH TAF
SITE...EXPECT VFR CONDITIONS WITH BREEZY WEST WINDS SUSTAINED
AROUND 15 KTS WITH GUSTS IN THE 20 TO 30 KT RANGE. WINDS WILL
DIMINISH AFTER SUNSET AND SKIES WILL BE CLEAR.

&&

.MARINE...A STRONG PRESSURE GRADIENT BETWEEN DEPARTING LOW PRESSURE
AND ARRIVING HIGH PRESSURE WILL YIELD NORTHWESTERLY WINDS BETWEEN 15
AND 20 KTS THROUGH THE DAY TODAY INTO THE OVERNIGHT HOURS. SMALL
CRAFT OPERATORS ARE URGED TO EXERCISE CAUTION THROUGH TONIGHT. AS
HIGH PRESSURE SETTLES IN OVERHEAD ON SUNDAY...WINDS AND SEAS WILL
FALL BELOW HEADLINE CRITERIA AND ARE EXPECTED TO REMAIN THAT WAY
THROUGH EARLY NEXT WEEK.

&&

.FIRE WEATHER...FOR TODAY WE WILL UPGRADE THE FIRE WEATHER WATCH TO
A RED FLAG WARNING DUE TO A COMBINATION OF LOW RH...BREEZY WINDS AND
HIGH DISPERSION. FOR SUN...WE WILL SEE THE LOWER HUMIDITY SPREAD
ACROSS ALL OF NORTH FLORIDA...BUT IT WILL BE MUCH LESS WINDY AND
DISPERSION INDICES WILL BE LOWER. THEREFORE...WE WILL NEED TO WAIT
FOR THE FORECAST ENERGY RELEASE COMPONENT TO DETERMINE IF RED FLAG
CRITERIA CAN BE MET ON THAT DAY. IT NOW APPEARS THAT RED FLAG
CRITERIA WILL BE MET FOR ALL OF OUR SE AL AND GA ZONES SO A WATCH
WILL BE IN PLACE FOR SUNDAY AFTERNOON. MOISTURE LEVELS WILL BEGIN TO
GRADUALLY INCREASE EARLY NEXT WEEK WITH THE ONSHORE FLOW.
