AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
938 AM EST MON JAN 25 2010
.SYNOPSIS...
A POWERFUL FRONTAL SYSTEM WILL SWEEP SLOWLY THROUGH THE AREA
TODAY. HIGH PRESSURE WILL THEN BUILD SOUTH OF THE
REGION...RESULTING IN FAIR WEATHER THROUGH WEDNESDAY. AN ARCTIC
FRONT WILL USHER IN COLD WEATHER FOR THE END OF THE WEEK WITH SNOW
POSSIBLE OVER THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WRMFNT HAS CLEARED THE CWA THIS MRNG WITH TEMPS AROUND 50. KMGJ
ROSE 13 DEGREES IN 1 HR. SOME OF THE LOWEST RIVER VALLEYS IN CT
HAVE NOT YET MIXED OUT BUT EXPECT THIS TO OCCUR BY OR SHORTLY AFT
SUNRISE.
HEAVIEST RAIN AS OF 8Z REMAINS ACROSS PA AND POINTS S. STLT
INDICATES UPR LOW NEAR LK SUPERIOR RETROGRADING WWD. UPR LOW OVER
IA WILL GET THE FRONTAL BOUNDARY MOVING EWD TODAY. A COMBO OF
RADAR/STLT/MODEL DATA WILL START THE SIG PCPN AFT 11Z WRN
ZONES...AFT 13Z METRO...AND AFT 15Z ERN CT/LI. BASED ON CURRENT
RADAR MOSAIC...THE HEAVIEST RNFL WILL OCCUR ABOUT AN HR OR TWO AFT
THE INITIAL MDT RAIN.
FOLLOWED CLOSER TO THE TIMING OF THE NAM FOR THE WIND FORECAST AS IT
HAS BEEN A STEP AHEAD OF THE GFS IN SLOWING THE TIMING OF COLD FROPA
FOR THE PAST SEVERAL MODEL RUNS. BOTH MODELS HOWEVER STILL
ADVERTISING WINDS NEAR 80 KT AT 850 MB. LATEST ACARS SOUNDINGS AND
FORECAST BUFKIT SOUNDING SHOW A STRONG INVERSION UP TO AROUND 950
MB...WITH WINDS FORECAST TO INCREASE TO 60-70 KT AT THIS LEVEL LATER
THIS MORNING INTO AFTERNOON. THIS INVERSION WILL BE TOUGH TO
BREAK...BUT THINK THAT HEAVIER DOWNPOURS AHEAD AND ALONG THE COLD
FRONT CAN MIX DOWN GUSTS TO ADVISORY CRITERIA LEVELS FROM GENERALLY
MID-MORNING THROUGH THIS AFTERNOON. COASTAL SECTIONS WOULD BE THE
MOST LIKELY LOCALES FOR SUCH GUSTS...AND AFTER COLLABORATION WITH
THE SURROUNDING OFFICES...HAVE CONVERTED THE FORMER HIGH WIND WATCH
TO A WIND ADVISORY DURING THIS TIME FRAME...AND HAVE ADDED OTHER
ZONES WHICH TYPICALLY GUST HIGHER THAN OTHERS IN THIS TYPE OF SETUP.
TEMPS TODAY WILL BE CLOSE TO RECORDS. READINGS ACROSS THE SERN
CONUS CONTINUE TO RISE THIS MRNG...AND THIS MILD AIR WILL BE
ADVECTED NWD ON STRONG SLY FLOW. ONLY LIMITING FACTOR IS THE COOL
WATER TEMPS WHICH SHOULD KEEP CSTL CT THE COLD SPOT TODAY WITH
SST/S ON THE SOUND IN THE 30S.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
SHRTWV CLIPS NRN PORTIONS OF THE CWA TNGT. SHRASN POSSIBLE WITH
THE FEATURE. MOISTURE WILL BE LIMITED AS THE FRONTAL BOUNDARY WILL
HAVE SWEPT THE DEEP MOISTURE OUT TO SEA. PCPN ENDS BY TUE
MRNG...WITH W FLOW PROVIDING MIXING UP TO H85. BLENDED A PURE MIX
DOWN OF TEMPS FROM H85 WITH THE MILD GMOS TO ACCOUNT FOR DOWNSLOPE
FLOW. SIMILAR METHOD USED FOR WED WITH CONTINUED W FLOW AND DEEP
MIXING. DRY FCST TUE/WED WITH LIMITED MOISTURE AND LACK OF
FORCING. SCT-BKN AFTN CU LIKELY BOTH DAYS AS SFC TEMPS REACH
CONVECTIVE.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/...
WEAK WAA THU AHEAD OF CDFNT. THIS MAY PRODUCE SOME LGT PCPN...RASN
TO RA COASTS AND SN TO RASN INTERIOR. ANY PCPN THU NGT CHANGES TO
-SN AS ARCTIC AIR BEGINS TO SPILL INTO THE CWA. TEMPS WILL FALL TO
BLW CLIMO FRI AND LAST THRU THE WEEKEND. MODELS CONTINUE TO
INDICATE THE DEVELOPMENT OF A SFC LOW OVER THE SERN CONUS ALONG THE
CDFNT...THEN TAKING IT OFFSHORE THE CWA OVER THE WEEKEND. 00Z GFS
DRY AND 00Z ECMWF CLIPS ERN ZONES. POPS UNCHANGED...BUT ATTM CSTL
LOCATIONS APPEAR TO BE FAVORED FOR SNOW THIS WEEKEND.
&&
.AVIATION /15Z MONDAY THROUGH FRIDAY/...
IFR CIGS/VSBYS CONTINUE TO SPREAD EAST IN MODERATE TO HEAVY RAIN.
THERE LOOKS TO BE A BREAK IN THE RAIN BEFORE THE COLD FRONT PUSHES
THROUGH THE REGION...BUT CONFIDENCE NOT HIGH ENOUGH TO TIME THIS
IN THE TAFS. WITH PASSAGE OF COLD FRONT...RAIN WILL PICK UP ONCE
AGAIN...AND THERE MAY BE A RUMBLE OF THUNDER AS WELL.
WINDS CONTINUE TO BE A MAJOR ISSUE. WILL BUMP UP WINDS THIS
MORNING TO 25-30KT WITH 40 KT GUSTS...INCREASING WITH PASSAGE OF
FRONT TO 25-35KT WITH 40-45 KT GUSTS. AFTER FRONT DEPARTS...WINDS
DIMINISH PRETTY QUICKLY THIS EVENING. LLWS ISSUES ALSO CONTINUE...
WITH 60+ KT WINDS AT ABOUT 2000 FT.
VFR WITH DIMINISHING WINDS TONIGHT.
OUTLOOK 12Z TUESDAY THROUGH FRIDAY...
TUESDAY THROUGH WEDNESDAY...VFR.
THURSDAY...SUB VFR POSSIBLE WITH LIGHT SNOW/RAIN MIX.
THURSDAY NIGHT...SUB VFR POSSIBLE WITH LIGHT SNOW.
FRIDAY...SUB VFR POSSIBLE LATE WITH SNOW ASSOCIATED WITH
POTENTIAL COASTAL LOW.
&&
.MARINE...
NOT ENOUGH CONFIDENCE FOR WIDESPREAD GUSTS TO 50 KT OVER THE WATERS
TODAY AS A STRONG INVERSION WILL BE TOUGH TO BREAK. WINDS ARE
FORECAST TO INCREASE TO 60-70 AT 950 MB...THE TOP OF THE
INVERSION...AND RAINFALL OUT AHEAD AND ALONG AN APPROACHING COLD
FRONT WILL LIKELY BRING GUSTS INTO THE GALE CATEGORY TODAY. GALE
WARNING WILL THEREFORE REMAIN UNCHANGED AND LAST THROUGH THIS
AFTERNOON. SEAS ON THE OCEAN EXPECTED TO BUILD UP TO 12-17 FT TODAY.
SMALL CRAFT ADVISORY WILL LIKELY BE NEEDED FOR ALL WATERS AT LEAST
INTO THE EVENING...BUT SEAS WILL LIKELY REMAIN ABOVE 5 FT ON THE
OCEAN WATERS THROUGH TONIGHT AND TUESDAY. A DECENT WESTERLY FLOW MAY
BRING MARGINAL SMALL CRAFT GUSTS TO THE OTHER WATERS ON TUESDAY.
SUB-SCA CONDITIONS FOR ALL WATERS MAY NOT OCCUR UNTIL WEDNESDAY
NIGHT. AN APPROACHING COLD FRONT WILL PROBABLY BRING SMALL CRAFT
CONDITIONS ON THURSDAY AND LAST INTO FRIDAY.
