Area forecast discussion, Apr 13, 9:42 AM CDT, 3 hours 11 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE TALLAHASSEE FL 1042 AM EDT MON APR 13 2009 UPDATED HEADLINES. REMAINDER OF DISCUSSION UNCHANGED. ...TORNADO WATCH IN EFFECT UNTIL 5 PM EDT FOR ALL BUT SOUTHEAST FLORIDA BIG BEND... ...SLIGHT RISK OF SEVERE WX ACROSS ENTIRE FORECAST AREA THROUGH TONIGHT... ...HEAVY RAIN POTENTIAL ACROSS THE REGION THROUGH TONIGHT... ...NEW RIVERINE FLOODING NOW FORECAST... .DISCUSSION...SURFACE ANALYSIS SHOWS WARM FRONT EXTENDING FROM LOW OVER THE MID MS VALLEY SEWD ACROSS AL TO THE FL PANHANDLE. KTAE SOUNDING SHOWS STRONGLY VEERED FLOW IN THE LOW LEVELS AND WE HAVE ALREADY GOTTEN A REPORT OF A POSSIBLE TORNADO IN GENEVA COUNTY AL. SBCAPE IS WORKING INTO WALTON COUNTY AND WE EXPECT STORMS TO BECOME SURFACE BASED THERE SOON. THE WARM FRONT LIFT LIFT NWD THROUGH THE DAY WITH MOISTENING AND MODEST HEATING OCCURRING IN THE WARM SECTOR. 50-60 KT SWLY MID LEVEL WINDS AND RIGHT ENTRANCE REGION OF UPPER JET WILL APPROACH FROM THE W. WE EXPECT SEVERE THREAT TO BE MAINTAINED AND CONVECTIVE WATCHES TO BE EXTENDED EWD. && .MARINE...SMALL CRAFT ADVISORY CURRENTLY IN EFFECT...ALTHOUGH WE MAY NOT REACH CRITERIA UNTIL THIS EVENING. WINDS AND SEAS WILL SHIFT TO WLY BEHIND THE COLD FRONT AND DROP INTO THE CAUTION RANGE DURING THE DAY TUE. WINDS WILL CONTINUE TO VEER TO NLY AND SUBSIDE THROUGH MID WEEK. && .AVIATION...LOOKING FOR MVFR TO BE THE PREVAILING CONDITION FOR MOST OF THE TAF PERIOD THROUGH 12Z TUE WITH PERIODS OF IFR OR LOWER IN CONVECTION. THIS ACTIVITY WILL NOT REACH TLH AND VLD UNTIL AFTERNOON. && .FIRE WEATHER...DRIER AIR MOVES IN ON TUE BUT RED FLAG THREAT WILL HOLD OFF UNTIL WED FOR THE FL ZONES. && .HYDROLOGY...THE CREST ON THE SUWANNEE PASSED DOWLING PARK LAST NIGHT AND WILL CONTINUE TO SLOWLY MOVE SOUTH THROUGH THE BASIN THROUGH THE REST OF THE WEEK...LEADING TO MODERATE FLOODING AT BRANFORD AND WILCOX AND MINOR FLOODING DOWNSTREAM. ELSEWHERE...FLOOD WATERS ARE CONTINUING TO SLOWLY RECEDE WITH LAMONT...SAINT MARKS AND BLOUNTSTOWN STILL ABOVE FLOOD STAGE. THE APPROACHING STORM SYSTEM IS EXPECTED TO DROP AROUND 2 INCHES OF RAIN ACROSS MOST OF THE AREA THROUGH TUESDAY MORNING WITH ISOLATED HIGHER AMOUNTS. THIS WILL LIKELY SLOW RECESSIONS AND MAY RESULT IN SOME NEW RISES. WELL UPDATE YOU WHEN THE NEW FORECASTS ARE AVAILABLE FROM THE SERFC. SMALL STEAMS AND CREEKS WILL BE SUSCEPTIBLE TO QUICK RISES TODAY IN AREAS THAT GET TRAINING OF ECHOES.

HTTP://AHPS.SRH.NOAA.GOV/INDEX.PHP?WFO=TAE && .PREV DISCUSSION... 400 AM EDT MON APR 13 2009 IN PROXIMITY TO WARM FRONT AND WELL AHEAD OF A COLD FRONT...AMPLE CONVECTION IN FORM OF ONGOING WAVY SQUALL LINE WITH EMBEDDED SMALL BOWS AND CLUSTER OF STORMS (MCS) FIRING UP AND EXTENDING FROM S/CNTRL MS INTO S/CENTRAL ALA W OF COFFEE COUNTY...THAT IS E OF SURFACE LOW AND BENEATH POTENT SHORTWAVE COINCIDENT WITH ADVANCING H85 JET AND 70-80 KT MIDLEVEL JET CORE. THIS ACTIVITY WILL CONTINUE TO MOVE EAST AND LIKELY REACH WRN COFFEE COUNTY B4 DAWN B4 SPREADING E/SE. WITH THE 00 UTC TAE SOUNDING STILL EXTREMELY DRY (PW=0.91) ...IT APPEARS THAT ADDITIONAL ISENTROPIC LIFT NEEDED TO INITIATE ANY SIGNIFICANT CONVECTION ACROSS REST OF CWA AND TAE SOUNDING WILL INCREASINGLY REFLECT 00Z LIX RAOB...WITH RAPIDLY MOISTENING UP OF LOW LEVELS AND STRONG SHEARING WITH HEIGHT. AT UPPER LEVELS... THE BIG CONUS PICTURE SHOWS A VERY AMPLIFIED PATTERN. FROM WEST TO EAST THIS IS HIGHLIGHTED BY TROUGH OVER ERN PAC...LARGE SCALE RIDGING BUILDING INTO THE WESTERN STATES/INTER-MOUNTAIN WEST...A POTENT TROUGH/CLOSED LOW EJECTING EASTWARD ACROSS THE SOUTHERN PLAINS WITH LOW PUSHING SLOWLY E-NE THROUGH SOUTHERN OKLAHOMA... LARGE SCALE RIDGING ACROSS ERN CONUS WITH AXIS ALONG I-75...AND A LARGE TROUGH/LOW PUSHING EAST AWAY FROM NORTHEAST/MID-ATLANTIC COAST. SRN PLAINS LOW WILL DEVELOP NEWD INTO OH VALLEY TODAY IN RESPONSE TO EWD PUSH OF PAC TROUGH. AS BASE OF DEEPENING TROUGH H5 80KT JET WILL PROPAGATE ACROSS GULF REGION. THIS WILL RESULT IN STEADY EWD PROGRESSION OF LARGE SCALE FORCING AND LARGE HEIGHT FALLS ALONG THE CENTRAL AND ERN GULF COAST REGION INTO TONIGHT. AT LOWER LEVELS... OVERNIGHT...STRONG HIGH PRESSURE CENTERED ALONG MID-ATLANTIC STATES HAS BEEN SHUNTED EWD AHEAD OF UPCOMING STORM SYSTEM AND IS NOW RIDGING DOWN TO JUST OFF ATLC COAST. LOW IN OK PANHANDLE AND A SECOND DEEPENING LOW NW TENN WITH (AT 4 AM EDT) A WARM FRONT SEWD THRU SW ALA..DHN AND INTO ERN APALACH BAY. COLD FRONT EXTENDED FROM LOW THRU CNTRL MISS AND INTO W/CNTRL GULF. THIS MARKS THE LEADING EDGE OF SIGNIFICANT HEIGHT FALLS. AS ABOVE UPPER TROUGH/LOW DIGS SEWD...SURFACE COLD FRONTS SHUNTED EWD. WARM FRONT WILL CONTINUE TO RETREAT TO THE NORTH...AND DEEP LAYER UPGLIDE CONTINUES TO INCREASE FROM W-E OVER OUR ZONES. AS GREATER HEIGHT FALLS APPROACH NEXT FEW HOURS...THIS BOUNDARY WILL ACCELERATE NWD WITH ACCOMPANYING HIGHER-THETAE BOUNDARY LAYER...PLACING MORE AND MORE OF CWA IN WARM SECTOR TRANSFERRING MUCH MORE UNSTABLE AIR ACROSS THE GULF COAST WITH DEWPOINTS IN THE MID AND UPPER 60S. SHORT TERM (TODAY THROUGH WEDNESDAY)... REST OF OVERNIGHT INTO EARLY MONDAY...WARM FRONT MOVES SW-NE ACROSS CWA. GOOD AGREEMENT THAT IT WILL SET UP FROM SOUTHERN AL TO THE FL PANHANDLE COAST WITH THE CONVECTION FROM ABOVE BOWING PUSHING IN SE ALA. BEST RAIN CHANCES/HIGHEST QPF WILL BE NORTH OF DOTHAN/ ALBANY. BY SUNRISE...THREAT FOR A FEW SEVERE STORMS SPREADING INTO WRN FL PANHANDLE/SE AL. REST OF THIS MORNING...THE GREATEST SEVERE WEATHER THREAT TO EXIST WHERE RICHER BOUNDARY LAYER MOISTURE AND RESULTANT STRONGER INSTABILITY WILL CO-EXIST WITH STRONG VERTICAL SHEAR AND APPROACHING SHORTWAVE...NAMELY NW THIRD OF CWA. EXPECT VERY IMPRESSIVE DEEP LAYER SHEAR VALUES OF 50-60 KNOTS WITH 50+ KNOT LOW LEVEL JET AXIS OVERHEAD. RESULTING LOW LEVEL SHEAR PROFILES ALONG AND NORTH OF THE WARM FRONT ARE VERY IMPRESSIVE WITH 0-3KM HELICITY...AND 0-1KM HELICITY IN THE 300+ RANGE. THE LINEAR NATURE OF THE SYSTEM MAKES STRAIGHT LINE WIND DAMAGE THE MAIN THREAT...HOWEVER THE LARGE HAIL THREAT WILL INCREASE AS THE WARM FRONT MOVES INLAND. ALSO AS FRONT APPROACHES EXPECT VEERING WIND PROFILE SO CAN NOT DISCOUNT TORNADO THREAT ASSOCIATED WITH ANY DISCRETE CELLS THAT MOVE ALONG OR CROSS THE WARM FRONTAL BOUNDARY. THIS BOUNDARY WILL SLOWLY MOVE N/NE THROUGH THE EARLY AFTERNOON SPREADING THE THREAT NORTHWARD ACROSS REST OF SOUTHEAST AL AND THEN INTO GA. WARM FRONT CONTINUES TO PUSH NORTH THROUGH THE AFTERNOON AS THE COLD FRONT APPROACHES FROM THE WEST ACROSS MS/AL. INFLOW OF HIGH PRECIPITABLE WATER CONTENT AIR WILL MAINTAIN THE RISK OF EXCESSIVE RAINFALL IN SLOW MOVING/TRAINING STORMS ESPECIALLY BY MIDDAY. THIS AFTERNOON... AS THE SYNOPTIC SUPPORT ASSOCIATED WITH THE UPPER TROUGH BUILDS EAST...EXPECTING AN INTENSIFYING SQUALL LINE AHEAD OF THE COLD FRONT TO MOVE INTO THE WESTERN/NW ZONES. MODELS INDICATE THAT THERE WILL MAY BE A BREAK BETWEEN THE MORNING ACTIVITY AND SQUALL THEN COLD FRONT REACHING CWA. THIS WILL ALLOW FOR HEATING AND FOR INSTABILITY VALUES TO RAPIDLY CLIMB DURING THE LATE MORNING AND EARLY AFTERNOON HOURS AS TEMPS WARM INTO THE MID AND UPPER 70S WITH DEWPOINTS IN THE 60S. AS COLD FRONT APPROACHES...DEEP LAYER SHEAR REMAINS HIGH WITH A WIDE SWATH OF 1500-2000J/KG CAPE. THREAT FOR LARGE HAIL AND DAMAGING WINDS...AND EVEN A FEW ISOLATED TORNADOES WILL CONTINUE WITH THIS LINE. THE SLOW MOVEMENT OF THE BAND...AND THE POTENTIAL FOR TRAINING FROM ALBANY TO DOTHAN AND SOUTH INTO THE PANHANDLE WILL HAVE TO BE MONITORED CLOSELY AS A FEW AREAS OF SIGNIFICANT RAINFALL OVER 3 CAN NOT BE RULED OUT. THIS EVENING INTO TONIGHT... SEVERE THREAT CONTINUES ACROSS THE WEST BUT ALSO EXPANDS EASTWARD ACROSS MUCH SW/S-CNTRL GA AND THE WESTERN BIG BEND. LATEST GUIDANCE SUGGESTS THAT MCS WILL DEVELOP...SAG SWD ALONG COLD FRONT AND MOVE ACROSS CWA OVERNIGHT WITH ALL MODES OF SEVERE WEATHER REMAIN POSSIBLE...HOWEVER IMPRESSIVE 7-8+ C/KM LAPSE RATES WOULD SUGGEST LARGE HAIL AND DAMAGING WINDS TO BE THE MAIN THREATS ESPECIALLY IF MCS HOLDS TOGETHER ALL NIGHT. COLD FRONT WILL ADVANCE INTO THE FORECAST AREA TONIGHT WITH THE SEVERE THREAT DIMINISHING AFTER ITS PASSAGE OVER THE WEST. ZONES EAST OF THE APALACHICOLA RIVER WILL LIKELY NOT SEE THIS FRONTAL PASSAGE INTO SOMETIME TUESDAY MORNING...AND THEREFORE AT LEAST AN ISOLATED SEVERE THREAT WILL CONTINUE AFTER MIDNIGHT. MIN TEMPS FROM MID 50S SE ALA TO MID 60S SE BIG BEND. TUESDAY... LARGE SCALE SUPPORT WILL FINALLY BEGIN TO EXIT THE REGION DURING THE DAY AS THE UPPER TROUGH MOVES OVERHEAD. SHOWER/STORMS WILL LIKELY LINGER THROUGH THE MORNING HOURS TOWARD THE SUWANNEE RIVER VALLEY BEFORE ENDING DURING THE EARLY AFTERNOON. SHARP 0-70% NW-SE POP GRADIENT...MAINLY MORNING PRECIP. THEN...PARTIAL CLEARING FROM W-E WITH BREEZY TO GUSTY WEST THAN NW WINDS. MAX TEMPS 70 SE ALA TO MID 70S SE BIG BEND. . TUESDAY NIGHT INTO WEDNESDAY... IN WAKE OF FRONT...SKIES CLEAR OUT WITH UNSEASONABLY CHILLY AIRMASS. HIGH PRESSURE RIDGING IN FROM THE NORTH WILL SUPPORT WIDESPREAD MIDDLE AND UPPER 40S AWAY FROM THE IMMEDIATE COAST. AMPLE SUNSHINE ON WED WITH TEMPS MID-UPPER 70S. LONG TERM...GUIDANCE IS IN FAIR AGREEMENT FOR THURSDAY INTO THE NEXT WEEKEND. UPPER RIDGE WILL BUILD INTO THE AREA BEHIND THE EARLY WEEK STORM SYSTEM. SLIGHTLY COOLER AIR WILL FILTER INTO THE REGION...BUT NOTHING EARTH SHATTERING. THE UPPER RIDGE AND WEAK SFC HIGH PRESSURE WILL REMAIN IN CONTROL THROUGH SATURDAY KEEPING THE WEATHER DRY AND AFTERNOON TEMPERATURES RIGHT AROUND 80 DEGREES.
