SYNOPSIS
A DRY AND WEAK COLD FRONT MOVES THROUGH EARLY TONIGHT
WITH SOME INTERVALS OF CLOUDS, AS HIGH PRESSURE BUILDS IN FOR
FRIDAY. SEASONABLE TEMPS CLOSE THE WEEK WITH THE SURFACE HIGH IN
CONTROL. AN UPPER LEVEL DISTURBANCE AND A COLD FRONT MAY BRING A FEW
SHOWERS AND THUNDERSTORMS NORTH OF THE CAPITAL REGION LATE SATURDAY
AFTERNOON INTO SUNDAY MORNING, AS FAIR AND DRY WEATHER WITH ABOVE
NORMAL TEMPERATURES RETURN NEXT WEEK.
SHORT TERM /THROUGH SATURDAY NIGHT/
AS OF 212 PM EDT...ANOTHER NICE LATE SUMMER DAY WITH ABUNDANT
SUNSHINE AND TEMPS WITH NEAR TO SLIGHTLY ABOVE NORMAL MAX TEMPS.
A WEAK COLD FRONT AND AN UPPER LEVEL TROUGH CONTINUE TO
APPROACH EASTERN NY AND WESTERN NEW ENGLAND THIS AFTERNOON AND
WILL MOVE ACROSS THE AREA EARLY TONIGHT WITH PARTLY CLOUDY
SKIES. THE BOUNDARY IS MOISTURE STARVED. A 1027 HPA OR SO SFC
ANTICYLONE WILL QUICKLY RIDGE IN FROM SOUTHEAST QUEBEC WITH
CLEAR/MOSTLY SKIES AND LIGHT TO CALM WINDS. SOME RADIATIONAL
MIST OR FOG IS POSSIBLE IN THE VALLEY AREAS WITH LOWS WIN THE
40S TO LOWER 50S, THOUGH SOME UPPER 30S ARE POSSIBLE IN THE
ADIRONDACK PARK.
HIGH PRESSURE WILL BRING MOSTLY SUNNY/SUNNY CONDITIONS DUE TO
THE SUBSIDENCE WITH THE RIDGE ON FRI WITH TEMPS NEAR NORMAL.
MAX TEMPS WERE USED CLOSER THE THE NBM AND GFS MOS AND ABOVE
THE COOLER MET MOS WITH HIGHS IN THE MID/UPPER 70S IN THE
VALLEYS AND 60S TO LOWER 70S OVER THE HIGHER TERRAIN.
FRI NIGHT INTO SAT...THE SFC ANTICYCLONE SLOWLY RETREATS OFF
THE NEW ENGLAND COAST FRI NIGHT. NEAR IDEAL RADIATIONAL COOLING
CONDITIONS AGAIN EARLY ON, BUT SOME MID/HIGH CLOUDS MAY INCREASE
FROM THE WEST LATE. LOWS WILL BE IN THE 40S WITH SOME LOWER 50S
IN THE MID HUDSON VALLEY AND NORTHWEST CT. THE WEEKEND SHOULD
OPEN MAINLY DRY, BUT APPROACHING SHORT-WAVE TROUGH AND A COLD
FRONT WILL CONTINUE TO INCREASE THE CLOUDS WITH A SLIGHT TO LOW
CHANCE OF A SHOWER OR THUNDERSTORM NORTHWEST OF THE CAPITAL
REGION IN THE LATE AFTERNOON. TEMPS AHEAD OF THE DISTURBANCE
WILL BE ABOUT 3-5 DEGREES ABOVE NORMAL WITH UPPER 70S TO CLOSE
TO 80F BELOW 1000 FT IN ELEVATIONS AND MID 60S TO MID 70S ABOVE
IT.
LIMITED LOW-LEVEL MOISTURE AND CONVERGENCE OCCURS WITH THE COLD
FRONT AND SHORT-WAVE, AND WE KEPT POPS 15-30% NORTH OF THE TRI
CITIES. THERE MIGHT BE SOME LIGHT SPRINKLES FURTHER SOUTH. LOWS
WILL BE IN THE UPPER 40S TO LOWER 50S OVER THE HIGHER TERRAIN
AND LOWER TO MID 50S OVER THE REST OF THE FORECAST AREA.
LONG TERM /SUNDAY THROUGH THURSDAY/
THE LATEST TRENDS WITH NBM AND THE ENSEMBLES ARE DRIER FOR THE
SECOND HALF OF THE WEEKEND WITH THE UPPER LEVEL TROUGH PASSAGE.
WE DID KEEP SOME SLIGHT CHANCE POPS NORTHEAST OF THE CAPITAL
REGION IN THE MORNING AND CLOSER TO THE I-84 CORRIDOR IN THE
LATE PM/EVENING BASED ON COLLAB WITH WFO OKX. SOME OF THE
DETERMINISTIC MEDIUM RANGE GUIDANCE KEEP ISOLATED TO SCATTERED
ACROSS THE REGION, SUCH AS THE GFS. BETTER MIXING IN THE WAKE
OF THE FRONT AND TROUGH SHOULD ALLOW TEMPS TO STILL RUN ABOVE
NORMAL TO CLOSE THE WEEKEND WITH MIXED CLOUDS AND SUNSHINE.
HIGHS IN THE UPPER 70S TO AROUND 80F WILL BE COMMON IN THE LOWER
ELEVATIONS AND MID/UPPER 60S TO MID 70S OVER THE HIGHS AND
MTNS.
OUR FORECAST REFLECTS DRIER TRENDS SUNDAY NIGHT INTO MONDAY WITH
HIGH PRESSURE BUILDING IN FROM SOUTHEAST CANADA. A CLOSED/CUT-
OFF LOW SETS UP OVER THE MID ATLANTIC STATES FOR MON-TUE. SOME
PERIODS OF CLOUDS OR LIGHT SPRINKLES COULD REACH THE SOUTHERN-MOST
ZONES EARLY IN THE WEEK. WE MAINTAINED A DRY FORECAST FOR NOW.
TEMPS CONTINUE TO TREND 5-7 DEGREES ABOVE NORMAL FOR MID-SEPT
WITH UPPER 40S TO MID 50S FOR LOWS AND HIGHS IN THE 70S TO LOWER
80S. THE REX BLOCK CONTINUES TO STRENGTHEN OVER THE EAST COAST
WITH HIGH PRESSURE OVER NY AND NEW ENGLAND AND THE CLOSED/CUT-
OFF LOW SOUTH OF THE REGION AND NEAR THE MID ATLANTIC COAST
THROUGH THE MID WEEK. IF THE HIGH WEAKENS, THEN POTENTIALLY SOME
MOISTURE COULD MOVE NORTHWARD. A FEW SHOWERS MAY GET CLOSE TO THE
ADIRONDACKS LATE THU FROM A COLD FRONT. HOWEVER, PERSISTENT DRY
CONDITIONS CONTINUE WITH TEMPS FINISHING THE MID WEEK ABOVE
NORMAL.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
FLYING CONDITIONS ARE CURRENTLY VFR ACROSS THE REGION. FEW-SCT
DIURNAL CU AROUND 5-6 KFT ARE DEVELOPING OVER THE AREA, ALONG
WITH SOME PASSING HIGH CIRRUS CLOUDS. THROUGH THE REST OF THE
DAY, IT WILL STAY VFR WITH A MOSTLY CLEAR SKY. NORTH TO
NORTHWEST WINDS WILL BE 5 TO 10 KTS THROUGH THIS AFTERNOON, BUT
THEY WILL START TO DIMINISH THIS EVENING WITH LOSS OF DAYTIME
HEATING.
WITH A WEAK UPPER LEVEL DISTURBANCE OVERHEAD, THERE MAY BE SOME
PASSING CLOUDS OVERNIGHT, MAINLY FOR KALB, KPOU AND KPSF. SCT-
BKN CIGS WILL BE 5-6 KFT THROUGH THE OVERNIGHT HOURS. MEANWHILE,
KGFL WILL STAY MAINLY CLEAR SO SOME FOG WILL DEVELOP THERE. IT
SHOULD DEVELOP AS EARLY AS 04Z OR SO AND WILL LIKELY BE IFR/LIFR
FOR THE LATE NIGHT HOURS, WITH VISIBILITY AS LOW AS 1/2SM. KPSF
MAY HAVE SOME FOG TOO, ALTHOUGH IT WILL DEPEND ON THE CLOUD
COVER THERE. IF THERE ARE ENOUGH CLOUDS, FOG MAY NOT FORM. FOR
NOW, WILL ANTICIPATE ENOUGH BREAKS TO ALLOW FOR A PERIOD OF IFR
FOG THERE JUST PRIOR TO SUNRISE FRIDAY.
ON FRIDAY, ANY LINGERING CLOUDS WILL BE CLEARING OUT DURING THE
MORNING HOURS AND ANY FOG WILL DISSIPATE. AS A RESULT, IT WILL
BE VFR THROUGH THE DAY ON FRIDAY WITH NO PRECIP AND A MOSTLY
CLEAR SKY. SURFACE WINDS WILL BE LIGHT AND VARIABLE THROUGH THE
DAY, MAINLY 5 KTS OR LESS.
