NWS Melbourne, FL wrote its last area forecast discussion before the first event at Feb 22, 2:45 PM EST, 2 hours 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 245 PM EST MON FEB 22 2010 .DISCUSSION... CURRENT...MAIN LINE OF STORMS OVER THE PANHANDLE AND NORTHERN FLORIDA STARTING TO LIE WEST TO EAST AS STRONG MID LEVEL FLOW ASSOCIATED WITH BROAD UPPER TROUGH MOVES QUICKLY THROUGH THE AREA. SOUTHWARD MOVING OUTFLOW BOUNDARIES FROM THE LINE OF STORMS OVER NORTHERN FLORIDA MAY TRIGGER A FEW STORMS OVER THE NORTHERN PORTIONS OF LAKE AND VOLUSIA COUNTIES THIS AFTERNOON. TO THE SOUTH...SHOWERS FINALLY STARTED FORMING IN THE SOUTH TO SOUTHWEST LOW LEVEL OVER SOUTHWEST FLORIDA AND WHERE TAKING AIM AT OSCEOLA AND OKEECHOBEE COUNTIES. NOT LOOKING AT ANYTHING TOO STRONG DUE TO DEW POINTS IN THE LOWER 60S AND THE LATEST RUC 850MB WINDS AROUND 25 TO 30 KNOTS. RUC 250MB WIND ANALYSIS WAS SHOWING THE JET AXIS OVER CENTRAL FLORIDA AND LIFTING NORTH DURING THE AFTERNOON AND EVENING PUTTING THE RIGHT FRONT CONVERGENT QUADRANT OVERHEAD WHICH SHOULD HELP TO SUPPRESS UPPER DIVERGENCE DUE TO THE JET STREAM. MOSTLY CLOUDY SKIES ALSO SHOULD LIMIT DAYTIME HEATING AND INSTABILITY BUT HAVE TO BE CAREFUL WHERE THERE ARE EDGES OF CLEARER SKIES FOR DIFFERENTIAL HEATING WHERE SHOWERS/STORMS COULD FORM LATER THIS AFTERNOON. TONIGHT-TUESDAY...FRONT MOVES WEST TO EAST ACROSS THE PENINSULA CLEARING OUR AREA TOWARD SUNRISE TUESDAY. DOWN THE PENINSULA IN A NORTH-SOUTH DIRECTION. PRECIP AND STORMS SHOULD BE WINDING DOWN AS VORTMAX MOVES INTO THE ATLANTIC AND THE FRONT RIGHT QUADRANT OF THE 250MB JET IS OVERTOP EAST CENTRAL FLORIDA. WITH THE MAIN LOW OFF THE CAROLINAS WILL HAVE TO WATCH FOR WRAP AROUND MOISTURE WHICH WOULD BRING LOW CLOUDINESS TO THE NORTHERN AND CENTRAL AREAS LATE TNGT AND FIRST PART OF TUESDAY. LOW CLOUDS ALONG THE BREVARD VOLUSIA COUNTY COAST SHOULD DIMINISH LATE MORNING AND THROUGH THE AFTERNOON AS THE LOW OFF NC LIFTS NORTHEAST AND MID LEVEL DRY AIR MOVES OVER THE AREA. WED-THU...SRN STREAM SHORTWAVE TROUGH WILL ZIP ALONG IN THE FAST ST JET FLOW FROM THE TX COAST AT 12Z WED AND ACROSS FL BY THU...BECMG NEARLY (BUT NOT QUITE) IN PHASE WITH THE STRONG NRN STREAM VORTEX WHICH CARVES ITSELF OUT OVER THE NERN-NORTH CTRL CONUS. 12Z GFS AND ECM SOLNS HAVE "MET IN THE MIDDLE" AS BOTH NOW SHOW A WEAK/SUPPRESSED WAVE FORMING JUST AHEAD OF THE REINFORCING FRONTAL BDRY NEAR THE YUCATAN CHANNEL. THE GFS IS FASTER WITH THE UPR TROUGH AND THUS SHOWS A LITTLE MORE IN THE WAY OF PARTIAL PHASING. THIS RESULTS IN A SFC LOW THAT'S STRONGER/FARTHER NORTH. ECM REMAINS UNPHASED...WEAKER AND LITTLE FARTHER SOUTH. AM TENDING TO LEAN TOWARD A SOLN IN BTWN THE TWO MODELS...MAYBE A LITTLE STRONGER THAN THE ECM...BUT FARTHER S THAN THE GFS WITH ANY SFC WAVE. BOTTOM LINE IS THAT WED IS SHAPING UP WETTER THAN BEFORE AND HAVE BUMPED UP POPS TO 50-60 FOR WED... WITH 20-30 FOR LINGERING SHRA ASCD WITH THE ACTUAL FROPA WED NGT. MUCH COOLER BY THU MORNING AS STRONG POST-FRONTAL CAA PUSHES MINS DOWN INTO THE U30S NORTH...L-M40S CTRL AND U40S-L50S SOUTH. WCI'S EXPECTED TO DIP INTO THE 30S ACROSS THE NRN HALF CWA BY SUNRISE THU. MUCH COOLER FOR THU WITH CONTINUED CAA AND MAXES IN THE U50S FAR NORTH TO M-U60S SOUTH UNDER SUNNY/MOSUNNY SKIES. FRI-MON (PREV)...THE UPPER FLOW CONTINUES NEAR ZONAL THROUGH THE PERIOD. STRONGER THAN NORMAL JET WINDS ALOFT (100+ KNOTS) WILL REMAIN CONSISTENT THROUGH THE WEEKEND. THE LATEST FRONTAL PASSAGE WILL KEEP BELOW SEASONAL (HIGHS/LOWS) CONDITIONS OVER THE REGION THROUGH THE EXTENDED. SURPRISING TO SEE THE GFS/ECM IN SUCH GOOD AGREEMENT THAT FAR OUT...ESPEC GIVEN THE FAST UPPER FLOW REGIME. NEVERTHELESS...THE NEXT WEATHER SYSTEM WITH CHANCE OF PRECIPITATION APPEARS ATTM AS IF IT WILL MOVE OVER THE GULF FRI NIGHT AND ACROSS THE PENINSULA DURING THE DAY SAT. FOR NOW WILL LIMIT POPS TO 20%. && .AVIATION...TEMPO MVFR/IFR CONDITIONS MAINLY DUE TO CEILINGS THROUGH THE EVENING AS THE FRONT WORKS IT WAY ACROSS CENTRAL FLORIDA. WILL HAVE TO WATCH FOR MVFR CEILINGS LATE OVERNIGHT AND TUESDAY MORNING DUE TO WRAPAROUND MOISTURE. && .MARINE...SOUTHERLY WINDS 15 TO 20 KNOTS AND 5 FOOT SEAS BEYOND 20 MILES. SOUTH TO SOUTHWEST WARM SECTOR WINDS WILL INCREASE THIS EVENING AS THE FRONT BEARS DOWN THE COASTAL WATERS. WINDS SHIFT TO THE WEST BEHIND THE FRONT. NOT LOOKING AT SMALL CRAFT ADVISORY WINDS ATTM. WED-SAT...WNW WINDS INTO EARLY WED ARE FCST TO SWING AROUND TO THE NE BRIEFLY AS A WEAK LOW PRES WAVE MOVES OVER SOUTH FL AHEAD OF THE FRONT WED. WINDS WILL SNAP BACK AROUND TO NWRLY AGAIN WED NIGHT AND INCREASE SIGNIFICANTLY WITH CONFIDENCE HIGH OF RAPID ONSET OF SCA CONDS SPREADING RAPIDLY N-S ACROSS THE ENTIRE MARINE AREA (0-60NM). SUSTAINED SPEEDS OF 25-30KTS OFFSHORE AND 20-25 KTS NEAR SHORE WED NIGHT/THU BEFORE SLACKING OFF THU NGT...BUT REMAINING NWRLY THRU FRI. SEAS START TO BUILD LATE WED AFTN THROUGH WED NGT/THU...BEFORE GRADUALLY SUBSIDING AGAIN ON FRI. && .FIRE WEATHER...NO MIN RH CONCERNS THROUGH WED. EXPECTING POTENTIAL LONG DURATION OF LOW RH THU/FRI AFTNS AS NORTHWEST-NORTHERLY FLOW ADVECTS A MUCH DRIER AIR MASS SOUTHEASTWARD DOWN THE FL PENINSULA. WILL LIKELY SEE WATCHES COME OUT SOMETIME ON TUE AS RFW CONDS SEEM PRETTY LIKELY TO VERIFY. && .PRELIMINARY POINT TEMPS/POPS...
