NATIONAL WEATHER SERVICE MELBOURNE FL
415 AM EST SUN DEC 16 2007
.DISCUSSION...
...STRONG STORMS REMAIN POSSIBLE THROUGH EARLY MORNING...
...MUCH COLDER BEGINNING THIS EVENING WITH LOW WIND CHILL READINGS
MONDAY MORNING...
CURRENT...
LOCAL 88D MOSAIC SHOWS HEAVIER PRECIP STARTING TO SPREAD ACROSS THE
NATURE COAST AND LAKE COUNTY....WHILE A LARGE GAP IN PRECIP COVERAGE
IS NOTED OFFSHORE FROM KSRQ SWD. THUS FAR TONIGHT...EMBEDDED
CONVECTION HAS BEEN PRETTY WEAK...WITH NO SUSPICIOUS ECHOES JUST
YET. SPC MESOANLYS FIELDS INDICATE IMPRESSIVE SFC-1KM HELICITY
VALUES OF 200-300M2/S2 AREAWIDE...HOWEVER SBCAPE IS PRETTY MINIMAL
OVER THE PENINSULA WITH CIN VALUES BTWN GENERALLY BTWN 50-150J/KG.
STILL CANT RULE OUT A FEW HIGHER DBZ STRONG ROTATING STORMS THROUGH
THE EARLY MORNING...BUT THUS FAR CONVECTION HAS BEEN PRETTY WELL
BEHAVED. OTHER ISSUE WILL BE LOCALLY HEAVY RAIN...THOUGH THIS MAY BE
CONFINED TO NRN HALF CWA...GIVEN THE RECENT DCRSG TREND IN RADAR
COVERAGE OFFSHORE SW FL.
TODAY/TONIGHT...
CONVECTIVE COMPLEX WILL SWEEP RAPIDLY EWD ACROSS THE PENINSULA
DURING THE EARLY MORNING...WITH A FEW TRAILING SHRA BANDS LINGERING
ACROSS THE SERN CWA THRU EARLY AFTN. AS WITH PRV FCSTS...PRECIP ENDS
AROUND 20-21Z...WITH RAPID CLEARING AND STRONG POST-FROPA CAA
PATTERN SETTING IN. IF MODEL PROGS ARE RIGHT...WINDS WILL STAY JUST
A BIT BELOW LK WND ADV CRITERIA. WILL FOREGO ISSUANCE FOR THE TIME
BEING...BUT WILL MENTION WINDY (15-20/GUSTY) IN THE ZONES.
MAV/MOS GUIDANCE HAS BEEN VERY PERSISTENT FOR THE LAST SEVERAL DAYS
IN SHOWING WCI VALUES DROPPING INTO THE U20S-L30S FOR A FEW HRS
BEFORE SUNRISE ACROSS THE NRN THIRD-HALF CWA...AND M-U30S OVER MUCH
OF THE REMAINDER OF THE CWA. CHILL WILL BE EVEN MORE NOTICEABLE
CONSIDERING THE ANTECEDENT SPATE OF WARM WX PRIOR TO THE FROPA. WILL
ISSUE NPW/ WIND CHILL ADVISORY FOR THE NRN CWA FOR EARLY MON MORNING.
MON-TUE...
A STRONG HIGH PRESSURE RIDGE BEHIND THE COLD FRONT WILL GENERATE A
COLD AIR ADVECTION PATTERN THRU THE FIRST PART OF THE WEEK. MOS
GUIDANCE HAS BEEN CONSISTENTLY FORECASTING BLO CLIMO TEMPS FOR THE
PAST SEVERAL MODEL RUNS BOTH MON/TUE. MONDAY WILL BE THE COLDEST AS
THE CENTER OF THE RIDGE AXIS REMAINS BACK TO THE NW...GENERATING A
LIGHT N/NWRLY SFC/BNDRY LYR FLOW. OVERALL...MIN TEMPS IN THE
M30S/L40S AND MAX TEMPS IN THE M50S/L60S WILL BE 10-15F DEG BLO
CLIMO. TEMPS WILL RECOVER SLIGHTLY ON TUE AS THE RIDGE AXIS PULLS
UP THE ERN SEABOARD AND WINDS SHIFT TO A SLIGHT ONSHORE COMPONENT.
NEVERTHELESS...THE NRLY WINDS WILL CONTINUE TO KEEP TEMPS 5F DEG
BLO CLIMO.
WED-SAT...
TEMPS SHOULD RECOVER TO CLIMO ON WED AS THE RIDGE WEAKENS OVER THE
WRN N ATLC. BOTH GFS/ECMWF MODELS MAINTAIN A TRAILING RIDGE AXIS
OVER THE DEEP S THRU THU...WHICH WILL ALLOW SFC/LOW LVL WINDS TO
SHIFT TO THE E AND ADVECT MARINE MODIFIED AIR ONSHORE. WINDS WILL
SHIFT TO THE SE ON THU AS THE NEXT STORM SYSTEM DEVELOPS OVER THE
MIDWEST AND PUSHES INTO THE OH RIVER VALLEY. THIS WILL SEND TEMPS
BACK ABV CLIMO BY 5-10F DEG THRU THE REST OF THE WEEK. LOW LVL RH
WILL INCREASE...BUT PRECIP CHANCES WILL REMAIN QUITE LOW AS A STRONG
H85-H70 SUBSIDENCE INVERSION ASSOCD WITH RIDGE KEEPS THE LCL AIRMASS
WELL CAPPED. WITH THE MODIFIED LYR LIMITED TO LESS THAN 10KFT...THE
AIRMASS WILL NOT BE ABLE TO HOLD ENOUGH MOISTURE TO SUPPORT ANYTHING
MORE THAN ISOLD POPS INTO THE WEEKEND.
ATTM...A NEW COLD FRONT IS FORECAST TO PUSH INTO THE DEEP S LATE IN
THE WEEK...BUT STRONG MID/UPR LVL ZONAL FLOW WILL PUSH THE STORM OFF
THE MID ATLC COAST TOO RAPIDLY FOR IT TO CRANK THE FRONT THROUGH THE
FL PENINSULA. FRONT SHOULD STALL OVER N FL...KEEPING TEMPS ABV
CLIMO AND POPS AOB 20%.
&&
.AVIATION...
WDSPRD MVFR VIS/CIGS IN RAIN AND EMBEDDED TSRA G30KT (PSBLY ISOLD
G50KT) WILL SWEEP ACROSS THE REGION FROM NW TO SE. TIME FRAME LOOKS
TO BE 08Z-13Z NORTH OF MCO-TTS AND 10Z-15Z TO THE SOUTH. RAPID
CLRING OF MVFR/HIGH END IFR CIGS BY 17Z-18Z NORTH AND 21-22Z SOUTH.
&&
.MARINE...
HAZARDOUS MARINE CONDS WILL DETERIORATE FURTHER WITH THE APPROACH
AND PASSAGE OF COLD FRONT. STRONG SRLY WINDS WILL SHIFT TO NW-N WITH
SEAS BUILDING UP TO AROUND 10FT IN THE GULF STREAM. MAY NEED TO
ISSUE SHORT FUSE SMW TO COVER GUSTS ALONG PREFRONTAL SQLN SHOULD IT
HOLD TOGETHER WITH ANY KIND OF VIGOR. SCA IS ALREADY IN PLACE - NO
NEED TO MODIFY.
STRONG RIDGE AXIS BEHIND THE COLD FRONT WILL PUSH OFF THE MID ATLC
AND NE COAST THRU TUE NIGHT. AS IT PUSHES ACROSS THE NRN GULF COAST
ON MON...IT WILL MAINTAIN A PGRAD TIGHT ENOUGH TO GENERATE 20-25KT
NRLY WINDS OVER THE N ATLC. WINDS/SEAS WILL DIMINISH MON NIGHT AS
THE RIDGE PULLS UP THE ERN SEABOARD BUT PROBABLY WILL REMAIN AT
CAUTIONARY LVLS THRU DAYBREAK TUE.
E/NE WINDS WILL PREVAIL THRU MID WEEK AS A WEAK SFC RIDGE REMAINS
OVER N FL...THEN WILL SHIFT TO THE SE ON THU AS THE NEXT STORM
SYSTEM MOVES INTO THE OH RIVER VALLEY AND THE SRN GREAT LAKES. AT
PRESENT...THE CENTER OF THE STORM SYSTEM IS EXPECTED TO PASS TOO FAR
TO THE N TO INCREASE WINDS TO SCA OR CAUTIONARY LVLS.
&&
.FIRE WEATHER...
RIDGE AXIS ON THE BACKSIDE OF THE FRONT WILL PRODUCE A STRONG DRY
AIR ADVECTION PATTERN ACROSS THE PENINSULA. THIS SHOULD DROP MIN RH
VALUES NEAR OR BLO CRITICAL LVLS OVER THE INTERIOR MON AFTN.
CRITICAL LVLS SHOULD BE LIMITED TO THE INTERIOR AS THE PROGRESSIVE
NATURE OF THE RIDGE WILL ALLOW A WEAK RETURN FLOW TO DEVELOP NEAR
THE COAST ON MON. WILL ISSUE A FIRE WX WATCH FOR THE INTERIOR
COUNTIES.
