AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 658 PM EDT WED SEP 22 2010 .SYNOPSIS... A WEAK COLD FRONT WILL MOVE THROUGH THE REGION THIS EVENING WITH SCATTERED SHOWERS AND THUNDERSTORMS. A SMALL AREA OF HIGH PRESSURE WILL MOVE THEN INTO THE REGION FOR LATE TONIGHT INTO THURSDAY. ANOTHER LOW PRESSURE SYSTEM WILL TRACK INTO THE GREAT LAKES LATE THURSDAY INTO FRIDAY...SENDING A SURGE OF VERY WARM AIR INTO THE REGION FRIDAY...AND FOLLOWED BY A COLD FRONTAL PASSAGE FOR FRIDAY NIGHT. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... ...SEVERE THUNDERSTORM WATCH 683 HAS BEEN CANCELLED... AS OF 658 PM EDT...HAVE CANCELLED SEVERE TSTM WATCH 683 FOR ULSTER/DUTCHESS/LITCHFIELD COS. BEST OVERLAP OF INSTABILITY AND DEEP LAYER SHEAR REMAINS WELL SOUTH OF OUR REGION...WITH JUST THE STRATIFORM AREA OF RAINFALL ON THE NORTHERN SIDE OF SOUTHERN MCS REACHING THE MID HUDSON VALLEY AND NW CT. CAN NOT RULE OUT A FEW RUMBLES OF THUNDER IN THIS AREA...BUT THE THREAT FOR SEVERE HAS ENDED WITH THE SETTING SUN. ELSEWHERE...HAVE TRIMMED BACK MENTION OF THUNDER FOR AREAS N OF THE CAPITAL REGION...AND HAVE ONLY INCLUDED ISOLATED MENTION OF THUNDER FROM THE CAPITAL REGION AND AREAS S AND E. PREVIOUS DISCUSSION FOLLOWS... AS OF 4 PM EDT...PARTLY TO MOSTLY CLOUDY SKIES REMAIN ACROSS NORTHERN AND CENTRAL AREAS...WITH MORE SUNSHINE ACROSS SOUTHERN AREAS. THE COMBINATION OF SBCAPES OF 500-1000 J/KG...AND 0-6 KM SHEAR OF 40+ KT...ALONG WITH A WEAK PREFRONTAL TROUGH APPROACHING FROM THE W...HAS CREATED AN ENVIRONMENT FAVORABLE FOR AT LEAST SCATTERED CONVECTION FOR SOUTHERN AREAS...WITH ISOLATED TO SCATTERED CONVECTION POSSIBLE FURTHER N INTO THE CAPITAL REGION. IN EXTREME SOUTHERN AREAS...WHERE INSTABILITY IS GREATER...THERE IS SOME CHC FOR SEVERE...AND A SEVERE TSTORM WATCH HAS BEEN ISSUED FOR ULSTER/DUTCHESS COS IN NY...AND LITCHFIELD CO IN CT UNTIL 11 PM EDT. IT APPEARS THE BEST CHC FOR ANY SEVERE CONVECTION MAY OCCUR THROUGH SUNSET IN THESE AREAS...WITH STRAIGHT LINE DAMAGING WINDS BEING THE MAIN SEVERE ATTRIBUTE. ELSEWHERE...SOME GUSTY WINDS ARE POSSIBLE WITHIN ANY DEEPER CONVECTION THAT DEVELOPS...BUT THE THREAT FOR SEVERE/DAMAGING WINDS APPEARS LESS. FOR AREAS N/W OF THE CAPITAL REGION...DYNAMICS ASSOCIATED WITH A PASSING SHORTWAVE...AND AN APPROACHING COLD FRONT SHOULD LEAD TO A PERIOD OF SCATTERED SHOWERS...WITH PERHAPS AN EMBEDDED THUNDERSTORM IN SOME AREAS. THIS POSSIBILITY OF SHOWERS SHOULD DIMINISH RATHER QUICKLY FROM NW TO SE AFTER SUNSET. THE THREAT FOR SHOWERS/TSTMS ACROSS S/E AREAS SHOULD DIMINISH RATHER QUICKLY AFTER MIDNIGHT FROM NW TO SE. SO...IT APPEARS ALL AREAS SHOULD BE DRY AFTER MIDNIGHT. PATCHY FOG AND/OR LOW CLOUDS MAY DEVELOP IN THE WAKE OF THE COLD FRONT...ESP IN ANY AREAS THAT RECEIVE RAINFALL THIS EVENING...AND IN NORTHEAST FACING...UPSLOPE AREAS WITHIN THE EASTERN CATSKILLS/HELDERBERGS. FOR MIN TEMPS...GENERALLY FOLLOWED A MAV/MET MOS BLEND. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... THU...AFTER ANY AREAS OF FOG/LOW CLOUDS BURN OFF BY MID MORNING...APPEARS TO BE PARTLY TO MOSTLY SUNNY IN MOST AREAS THROUGH AT LEAST EARLY AFTERNOON. HOWEVER...STRENGTHENING MID LEVEL WARM ADVECTION DEVELOPS DURING THE AFTERNOON...ESP ACROSS NW AREAS. THIS MAY LEAD TO ISOLATED TO SCATTERED SHOWERS/TSTMS TOWARD SUNSET...MAINLY ACROSS THE WESTERN MOHAWK VALLEY AND DACKS. MIXING SHOULD BE RELATIVELY SHALLOW...GENERALLY ONLY TO BETWEEN 925-900 HPA...WITH EXPECTED MAXES CLOSE TO THE MAV MOS...YIELDING MAINLY 70-75 WITHIN THE VALLEYS...EXCEPT 75-80 ACROSS THE MID HUDSON VALLEY...WITH MAINLY 60S ACROSS THE DACKS. THU NT...STRONG MID LEVEL WARM ADVECTIVE BURST OCCURS IN THE EVENING ACROSS NW AREAS...AND AS SUCH...HAVE INDICATED SLIGHT CHC TO CHC POPS...HIGHEST ACROSS THE WESTERN DACKS THROUGH MIDNIGHT. THE SHOWERS/TSTMS SHOULD LIFT MAINLY N OF THE CWA AFTER MIDNIGHT. EXPECT AN INCREASING SOUTH WIND UP THE HUDSON RIVER VALLEY THROUGH THE NIGHT...WHICH SHOULD KEEP MIN TEMPS GENERALLY IN THE LOWER/MID 60S CLOSE TO THE CAPITAL REGION AND AREAS ADJACENT TO THE HUDSON RIVER...WITH MAINLY 50S ELSEWHERE. THERE IS SOME HINT THAT A LOW CLOUD DECK MAY DEVELOP AND/OR ADVECT ACROSS SE AREAS LATE THU NT AS INDICATED WITHIN 12Z SOUNDINGS AND WITHIN THE 1000-925 HPA NAM12 RH FIELDS...AS WELL AS WITHIN THE 09Z/22 SREF CIG/CLOUD PRODUCT...ESP ACROSS THE MID HUDSON RIVER VALLEY MAINLY E OF THE HUDSON RIVER...INTO NW CT AND THE BERKSHIRES...AND HAVE THEREFORE INCREASED CLOUD COVERAGE IN THESE AREAS AFTER 06Z/FRI. FRI...OTHER THAN THE POSSIBILITY OF LINGERING LOW CLOUDS ACROSS SE AREAS...EXPECT PARTLY TO MOSTLY SUNNY SKIES. HOWEVER...HIGH CLOUDS COULD DEVELOP AND OR DRIFT ACROSS THE REGION...WHICH COULD LIMIT FULL MIXING POTENTIAL SOMEWHAT. AT THIS TIME...HAVE GENERALLY GONE CLOSER TO THE COOLER MAV MOS IN MOST AREAS...WHICH HAS BEEN A STELLAR PERFORMER AS OF LATE...WITH MAXES GENERALLY REACHING THE LOWER/MID 80S ACROSS THE HUDSON RIVER VALLEY FROM ALBANY NORTHWARD...TO MID/UPPER 80S SOUTH OF ALBANY...WITH MAINLY UPPER 70S TO LOWER 80S ACROSS HIGHER ELEVATIONS. HOWEVER...SHOULD THERE BE LESS HIGH CLOUDS...THE POTENTIAL FOR HIGHER TEMPS...POSSIBLY REACHING 85-90...WILL BE POSSIBLE. THE RECORD MAX FOR ALBANY FRIDAY IS 87 DEGREES...WHICH AT THIS TIME...IS FORECAST TO HOLD. BUT...AGAIN...LESS HIGH CLOUDS COULD PUT THIS IN JEOPARDY. FRI NT...MOST DETERMINISTIC AND ENSEMBLE GUIDANCE INDICATE THAT ALTHOUGH A STRONG COLD FRONT WILL CROSS THE REGION FRI NT...MOISTURE AVAILABILITY AND LOW LEVEL CONVERGENCE MAY BE QUITE LIMITED. HAVE THEREFORE CONFINED CHC POPS TO FAR NORTHERN AREAS...WITH ONLY SLIGHT CHC POPS AFTER MIDNIGHT ELSEWHERE. DESPITE POSSIBLE LIMITED CONVECTION...STRONG LOW AND MID LEVEL WIND FIELDS WILL DEVELOP FRI NT...SOME OF WHICH COULD MIX DOWN OCCASIONALLY ACROSS HIGHER ELEVATIONS...AND WITHIN SOME VALLEYS. WILL ENHANCE WIND GUSTS TO 20-35 MPH FOR FRI NT...WITH STRONGEST GUSTS EXPECTED LATE AT NIGHT AS COOL AIR ADVECTION DEVELOPS ABOVE 800 MB. OTHERWISE...EXPECT A RATHER WARM NIGHT...WITH MINS GENERALLY HOLDING 65-70 WITHIN THE HUDSON RIVER VALLEYS...WITH 50S TO LOWER 60S EXPECTED ACROSS HIGHER ELEVATIONS. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... LARGE DIFFERENCES CONTINUE TO EXIST WITH THE EVOLUTION OF A LARGE CUT OFF UPPER LOW DEVELOPING OVER THE THE WEEKEND. THE GFS CUTS A LOW OFF NEAR OKLAHOMA/ARKANSAS SUNDAY WITH THE FEATURE MOVING LITTLE THROUGH EARLY NEXT WEEK. WHILE THE ECMWF CUTS OFF A LOW FARTHER TO THE EAST NEAR IL/MO/KY AND IS MORE PROGRESSIVE WITH ADDITIONAL ENERGY DIVING INTO THE LONGWAVE TROUGH MOVING THE FEATURE NORTHEASTWARD. WITH SUCH LARGE DIFFERENCES IN THE LONGWAVE PATTERN HAVE FAVORED HPC GUIDANCE FOR THE PERIOD WHICH FAVORS THE ECMWF AND ITS ENSEMBLE MEAN SOLUTIONS. REFER TO HPC'S EXTENDED FORECAST DISCUSSION (PMDEPD) FOR MORE DETAILS.

KGFL AND KPOU WIND SPEEDS WILL GO CALM...WHILE KALB WIND SPEEDS WILL REMAIN LIGHT OVERNIGHT. WITH CLEARING SKIES AND SUBSIDING WINDS...EXPECT SOME MVFR FG/BR TO DEVELOP AFTER MIDNIGHT...WITH KGFL FURTHER DETERIORATING TO IFR VSBYS AROUND 07Z. AFTER SUNRISE...ALL TERMINALS WILL IMPROVE TO VFR CONDITIONS... BUT WIND SPEEDS SHOULD REMAIN LIGHT AT 3-6 KTS.
