AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
616 AM EDT TUE SEP 1 2015

.SYNOPSIS...
A STRONG UPPER LEVEL RIDGE WILL ALLOW FOR UNSEASONABLY WARM
CONDITIONS THROUGH MUCH OF THE WEEK. IT LOOKS TO BE RAIN FREE MOST
OF THE TIME...ALTHOUGH A SHOWER OR THUNDERSTORM CANNOT BE TOTALLY
RULED OUT ON THURSDAY...AS A COLD FRONT APPROACHES THE AREA FROM
THE NORTH.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 615 AM EDT...SOME PATCHY LOW CLOUDS CONTINUE ACROSS
PORTIONS OF THE WESTERN ADIRONDACKS...MOHAWK VALLEY...SCHOHARIE
VALLEY AND EASTERN CATSKILLS...AS WELL AS PORTIONS OF SW VT AND
WESTERN MA. IN ADDITION...PATCHY FOG HAS FORMED IN AREAS WHERE
SKIES REMAINED CLEAR OVERNIGHT.

WE EXPECT THE LOW CLOUDS/FOG TO BURN OFF/DISSIPATE BETWEEN 8 AND
10 AM...LAST ACROSS THE EASTERN CATSKILLS/WESTERN MOHAWK VALLEY.
THEN...EXPECTING MOSTLY SUNNY SKIES FOR TODAY...WITH LIGHTER WINDS
THAN MONDAY. MAX TEMPS SHOULD BE SLIGHTLY COOLER COMPARED TO
MONDAY...WITH SLIGHTLY MORE SHALLOW MIXING DEPTH IN PLACE. STILL
EXPECT WIDESPREAD MID TO UPPER 80S IN VALLEYS...AND LOWER 80S FOR
MOST HIGHER TERRAIN. IT WILL REMAIN A BIT HUMID...WITH DEWPOINTS
MAINLY IN THE LOWER/MID 60S.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/...
TONIGHT...GENERALLY CLEAR SKIES AND LIGHT WINDS...WITH PATCHY FOG
POSSIBLY FORMING AFTER MIDNIGHT. MIN TEMPS SHOULD FALL INTO THE
MID 50S TO LOWER 60S...COOLEST ACROSS PORTIONS OF THE SOUTHERN
ADIRONDACKS/UPPER HUDSON RIVER VALLEY AND SOUTHERN VT.

WEDNESDAY...MOSTLY SUNNY...AND A BIT HOTTER THAN TODAY DUE TO A
SLIGHTLY GREATER MIXING DEPTH...AND EVEN WARMER TEMPS ALOFT.
EXPECT MAX TEMPS TO REACH 85-90 IN VALLEYS...AND 80-85 ACROSS MOST
HIGHER ELEVATIONS. SOME LOWER 90S WILL BE POSSIBLE IN PORTIONS OF
THE MID HUDSON VALLEY. THESE MAX TEMPS...COMBINED WITH DEWPOINTS
IN THE MID 60S...WILL PRODUCE MAX HEAT INDICES OF 90-95 IN
VALLEYS...AND 85-90 ACROSS HIGHER ELEVATIONS.

WEDNESDAY NIGHT...A COLD FRONT WILL SLOWLY APPROACH FROM SOUTHERN
CANADA LATE AT NIGHT. SOME HI-RES MESOSCALE MODELS SUGGEST SOME
REMNANT CONVECTION MAY APPROACH THE SOUTHERN ADIRONDACKS DURING
THE NIGHT BEFORE WEAKENING. WILL KEEP SOME SLIGHT CHC POPS IN THIS
REGION IN CASE SOME SHOWERS OR THUNDERSTORMS CAN BE MAINTAINED
BEFORE ULTIMATELY WEAKENING. IT WILL BE WARM AND HUMID...WITH MIN
TEMPS ONLY FALLING INTO THE MID/UPPER 60S IN VALLEYS...AND LOWER
60S ACROSS HIGHER ELEVATIONS.

ON THURSDAY...A WEAK FRONTAL SYSTEM WILL BE SETTLING SOUTHWARD
ACROSS THE REGION. OVERALL MOISTURE WILL BE LIMITED...AND DYNAMICS
WEAK...SO ONLY EXPECTING ISOLATED TO PERHAPS SCATTERED
SHOWERS/THUNDERSTORMS TO PRECEDE/ACCOMPANY THE BOUNDARY AS IT
SETTLES SOUTHWARD...WITH THE GREATEST THREAT FOR A
SHOWER/THUNDERSTORM ACROSS HIGHER ELEVATIONS EAST AND WEST OF THE
HUDSON VALLEY IN THE AFTERNOON. WINDS ALOFT WILL BE FAIRLY
WEAK...BUT INSTABILITY MAY BE FAIRLY HIGH...SO CAN NOT COMPLETELY
RULE OUT A STRONGER THUNDERSTORM OR TWO WITH LOCALLY GUSTY WINDS.
MAX TEMPS SHOULD REACH 85-90 IN VALLEYS AND LOWER TO MID 80S
ACROSS HIGHER ELEVATIONS.

THURSDAY NT...AN ISOLATED SHOWER/THUNDERSTORM THREAT MAY LINGER
INTO THE EARLY EVENING ACROSS PORTIONS OF THE MID HUDSON VALLEY
AND NW CT...OTHERWISE FAIR CONDITIONS WITH SLIGHTLY COOLER/LESS
HUMID AIR ADVECTING SOUTHWARD OVERNIGHT. MIN TEMPS BY FRI AM
SHOULD REACH THE MID 50S TO LOWER 60S...WARMEST ACROSS THE MID
HUDSON VALLEY AND LOWER ELEVATIONS IN NW CT.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
A LARGE RIDGE OF HIGH PRESSURE AT THE SURFACE AND ALOFT WILL BE THE
DOMINANT WEATHER FEATURE ACROSS OUR REGION THROUGH THE END OF THE
