...STRONG TO SEVERE THUNDERSTORMS POSSIBLE TODAY...
.PUBLIC UPDATE...WARM FRONTAL BOUNDARY IS CURRENTLY POSITIONED BETWEEN
JACKSONVILLE AND GAINESVILLE AND THIS FEATURE WILL CONTINUE TO LIFT
NORTHWARD THE BALANCE OF TODAY. STRONG DYNAMICAL FORCING CURRENTLY
RESIDES NORTH OF THE I-10 CORRIDOR...AND DOPPLER RADARS INDICATES
MODERATE TO HEAVY RAINS ALONG WITH THUNDERSTORMS NORTH OF THIS
CORRIDOR...ESPECIALLY ACROSS SOUTHEAST GEORGIA. THUNDERSTORMS SO FAR
HAVE BEEN ELEVATED AS BOUNDARY LAYER CONDITIONS HAVE GENERALLY BEEN
STABLE WITH LARGE AREA OF CIN ABOVE THE SURFACE...AS EVIDENCED BY
BOTH THE JACKSONVILLE AND TALLAHASSEE SOUNDINGS. AS STORM SYSTEM
OVER THE LOWER MISSISSIPPI VALLEY CONTINUES TO ADVANCE TOWARDS THE
SOUTHEAST STATES...AFOREMENTIONED WARM FRONTAL BOUNDARY WILL LIKELY
EVENTUALLY LIFT NORTHWARD ACROSS SOUTHEAST GEORGIA WITH MUCH OF THE
AREA IN THE WARM SECTOR. THIS IN COMBINATION WITH CONTINUED STRONG
DYNAMICAL FORCING AND INCREASED INSTABILITY WILL PROMOTE STRONG TO
SEVERE THUNDERSTORMS TODAY...WITH CONCERNS OF DAMAGING WINDS AND
HAIL. IN ADDITION...DIRECTIONAL AND SPEED SHEAR FROM SURFACE TO 3KM
WILL FAVOR ROTATING THUNDERSTORMS WITH POTENTIAL FOR TORNADOES/
WATERSPOUTS. IN RESPONSE...A TORNADO WATCH IS IN EFFECT FOR

SCATTERED TO NUMEROUS SHOWERS WITH LOCALIZED THUNDERSTORM WILL
CONTINUE TO IMPACT AREA TERMINALS FOR MUCH OF TODAY...WITH GUSTY
WINDS ACCOMPANYING THE HEAVIER SHOWERS AND THUNDERSTORMS SOUTH OF
THE WARM FRONT. AS MENTIONED EARLIER...THERE IS STILL THE POTENTIAL
FOR A SQUALL LINE TO PUSH THROUGH THE AREA THIS AFTN AND EVENING

.PREVIOUS PUBLIC...A STRONG STORM SYSTEM WILL BE TRACKING ACRS THE DEEP
SOUTH TODAY WITH THE MID/UPR LOW MOVING OVER THE MS VALLEY INTO THE
WRN TN VALLEY BY EVENING. MSAS ANALYSIS PLACES THE SFC LOW OVER WRN
ARKANSAS EARLY THIS MORNING AND DEWPOINT ANALYSIS PLACES A WARM
FRONT THRU MS...SRN AL TO THE FL PANHANDLE WITH DEW POINTS IN THE
MID 60S S OF THE FRONT. CONVECTION IS ONGOING ALONG AND N OF THE
WARM FRONT. IMPRESSIVE JET DYNAMICS ARE ALSO IN PLACE. THE
CONVECTION IS LOCATED NEAR THE LEFT FRONT EXIT REGION OF A 120KT TO
140KT UPR JET. A 40KT TO 50KT SOUTHERLY LOW LEVEL JET IS FEEDING
INTO THE STORMS AND PER SPC...WILL ENHANCE THE LOW LVL WIND SHEAR.
THIS RAISES THE CONCERN FOR ISOLD TORNADOES. THE WARM FRONTAL
CONVECTION WILL CONTINUE TO LIFT NEWD THIS MORNING WITH NEAR 100%
CHANCE OF STORMS FOR AREAS SE GA TAPERING OFF TO CHANCE FOR RAIN IN
THE SE PORTION. A SECONDARY SFC LOW WILL DEVELOP OVER SE GA THIS
AFTN AND A SQUALL LINE IS ANTICIPATED TO MOVE OVER THE AREA DURING
THE AFTN AND EARLY EVE. OUR SOUTHERN MOST COUNTIES WILL RECEIVE PART
SUNSHINE EARLY IN THE DAY ALLOWING TEMPS TO REACH UPR 70S AND
PROVIDE ENOUGH TIME FOR DESTABILIZATION AND POTENTIAL FOR STRONGER
STORMS AS THE SQUALL LINE MOVES THRU. OUTSIDE OF ANY
CONVECTION...BREEZY SW WINDS ARE EXPECTED ESPECIALLY ALONG AND W OF
THE I-75 CORRIDOR. THIS LATTER AREA MAY NEED A LAKE WIND ADV...BUT
FOR NOW WILL KEEP WINDS AT 15 TO 20 MPH WITH GUSTS TO NEAR 30 MPH.
BY FRIDAY MORNING ONLY THE FAR SOUTH PORTION WILL HAVE LINGERING
RAIN CHANCES...THEN SKIES WILL GRADUALLY CLEAR IN THE AFTERNOON.
AIR MASS MOVING IS OF PACIFIC ORIGIN AND TEMPS WILL REMAIN NEAR
CLIMO OR 5 DEG ABOVE NORMAL FOR NE FL. WHAT FOLLOWS IS A
PROGRESSIVE WEATHER PATTERN AS A RIDGE BUILDS INTO THE AREA FROM
LATE FRI TO SAT AFTN THEN MOVES INTO THE ATLANTIC SAT NIGHT. A SFC
RIDGE ALONG THE EAST COAST SATURDAY WILL BRING NELY WINDS AND
PARTLY CLOUDY SKIES TO THE REGION KEEPING SE GA AND NE FL COAST IN
THE 60S...BUT SW PORTION WILL REACH LOWER 70S.
LONG TERM...NEXT COLD FRONT IS PROGGED TO MOVE THROUGH THE AREA LATE
SUNDAY NIGHT INTO MONDAY MORNING. JET DYNAMICS LOOK IMPRESSIVE AGAIN
BUT INSTABILITY MORE LIMITED THAN PREVIOUS SYSTEM. COULD STILL HAVE
A FEW STRONG STORMS AS LOCAL AREA IS WITHIN RIGHT FRONT ENTRANCE RGN
OF UPR JET. DRY SLOT MOVES THROUGH MONDAY AFTERNOON AND NIGHT
FOLLOWED BY PARTLY CLOUDY AND MUCH COOLER CONDITIONS TUE/WED AS HIGH
PRESSURE BUILDS IN FROM THE WEST. TEMPS BELOW CLIMO NEXT WEEK WITH
