Severe Thunderstorm Warning 159, NWS Tallahassee, FL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
355 PM EDT TUE JUL 22 2008

.SYNOPSIS...DOLLY CONTINUES TO LOOK MORE IMPRESSIVE ON SATELLITE
IMAGERY WITH CONVECTION INCREASING AROUND A DEVELOPING EYE. CLOSER
TO HOME, THE MCV FROM LAST NIGHTS CONVECTION IS STILL EVIDENT IN
VISIBLE SATELLITE IMAGERY OVER E CENTRAL GA. A VORT LOBE EXTENDS
FROM THE MCV NWWD INTO NW GA AND THE DPVA AHEAD OF IT IS SPARKING
CONVECTION ACROSS W CENTRAL GA ALONG AN OLD BOUNDARY. OVER FL,
CONVECTION GOT AN EARLY START BETWEEN 15-16Z AND IS SETTING UP LIKE
WE WOULD EXPECT IN THIS FAVORABLE SEA BREEZE REGIME (W AROUND 10 KT
IN THE 1000-700 MB LAYER). ENERGY CONTINUES TO ROTATE AROUND THE ERN
N AMERICAN TROUGH AS IT GRADUALLY AMPLIFIES.

&&

.SHORT TERM...TONIGHT THROUGH THU NIGHT.
THE EVENING POP GRID REFLECTS EXPECTED RADAR TRENDS RATHER THAN ANY
MODEL GUIDANCE WHICH HAS BEEN HORRIBLE OF LATE. THE FL CONVECTION IS
CONTINUES OVER THE PANHANDLE, BUT THE STRONGER STORMS ARE PUSHING
INTO OUR GA ZONES. OUTFLOW FROM BOTH OF THESE AREAS WILL INTERSECT
OVER OUR SW AND S CENTRAL GA ZONES AND THAT IS WHERE OUR HIGHEST
REFLECTIVITIES LIE. FOR WED, WE RELIED HEAVILY ON OUR SEA BREEZE
CLIMO, WITH LIKELY POPS IN FL. EVEN ACROSS THE NRN ZONES, WE WENT
WITH A 50 POP WHERE AN OTHER MCS/MCV MAY ARRIVE LATE IN THE DAY IN
THE CONTINUED NWLY FLOW. BY THU, THE FLOW WILL VEER TO NWLY WHICH
MEANS LOWER POPS, SLIGHTLY HIGHER S THAN N.

.LONG TERM...FRI THROUGH TUE.
THE 00 GFS AND ENSEMBLE MEAN AND 12 UTC MONDAY ECMWF FORECAST OUR
AREA TO BE NEAR THE BASE OF A 500 MB TROUGH OVER THE EASTERN CONUS
THROUGHOUT THE PERIOD. THIS HAS BEEN A COMMON PATTERN THIS
SUMMER...AS THIS MEAN TROUGH SPLITS A STRONG BERMUDA HIGH OVER THE
WESTERN ATLANTIC FROM THE STRONG RIDGE OVER THE WESTERN CONUS. THEY
ARE ALSO IN AGREEMENT IN KEEPING THE EAST-WEST ORIENTED WEST
ATLANTIC SURFACE RIDGE TO OUR SOUTH. THE GUIDANCE FORECASTS A POCKET
OF MID-UPPER LEVEL DRY AIR OVER OUR AREA FRIDAY...BUT THEN INCREASE
THE DEEP LAYER MOISTURE TO NEAR TYPICAL VALUES BY THE WEEKEND AND
INTO EARLY NEXT WEEK. THIS WOULD IMPLY NEAR CLIMATOLOGY POP AND
TEMPERATURES...AND THAT IS WHAT THE LATEST GFS MOS IS FORECASTING.

&&

.MARINE...TONIGHT THROUGH SUN.
SWELL PERIODS FROM DOLLY CONTINUE TO GRADUALLY DECREASE, AND THIS
TREND WILL CONTINUE OVERNIGHT. WE CONTINUE TO MENTION MAINLY SWELL
CONDITIONS THROUGH WED NIGHT. OTHER THAN THIS SWELL AND LOCALLY
HIGHER WINDS AND SEAS IN CONVECTION...WINDS AND SEAS WILL BE LOW
FROM THU THROUGH THE END OF THE PERIOD.

&&

.AVIATION...SCT-NMRS SHOWERS AND STORM HAVE DEVELOPED BETWEEN KTLH
AND KPFN EARLY THIS AFTERNOON WITH THE COMPLEX DRIFTING SLOWLY NORTH
AND NORTHEAST. KPFN WILL SEE STORMS IN THE AREA UNTIL THE LATER
AFTERNOON WHEN MOST OF THE ACTIVITY SHOULD MIGRATE INLAND WITH KTLH
HAVING THE BEST CHANCES TO SEE A STORM LATE AFTERNOON AND EARLY
EVENING. FURTHER NORTH TOWARD KDHN AND KABY CU DEVELOPMENT HAS BEEN
SLOW TODAY AND SCT SHOWER/STORM DEVELOPMENT IS LIKELY TO WAIT TILL
LATE IN THE DAY AND MORE SO EVENING. OVERNIGHT EXPECT AREAS OF
MIST/HZ AFTER MIDNIGHT WITH VIS GENERALLY IN THE MVFR RANGE. KVLD
MAY ONCE AGAIN APPROACH IFR VIS LATE AT NIGHT. SCT STORMS EXPECTED
TO DEVELOP REGION-WIDE BY EARLY AFTERNOON WEDNESDAY.

&&

.FIRE WEATHER...NO CONCERNS.
