AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
417 AM EDT MON AUG 31 2015

.SYNOPSIS...
THIS WEEK WILL BE HOT AS HIGH PRESSURE BUILDS IN ACROSS
THE REGION AT THE SURFACE AND ALOFT. HIGHS MAINLY IN 80S ARE
EXPECTED MUCH OF THE WEEK...WITH SOME 90S ANTICIPATED WITHIN THE
HUDSON RIVER VALLEY DURING THE MIDDLE AND LATTER PART OF THE WEEK.
GENERALLY DRY CONDITIONS ARE EXPECTED THROUGH WEDNESDAY...WITH JUST
AN ISOLATED SHOWER OR THUNDERSTORM POSSIBLE THURSDAY AND FRIDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 410 AM EDT...HIGH CLOUDS CONTINUE TO STREAM ACROSS SOUTHERN
AREAS...IN ASSOCIATION WITH AN UPPER LEVEL DISTURBANCE APPROACHING
FROM THE MID ATLANTIC STATES...AND ALSO SOUTH OF A WEAKENING UPPER
LEVEL TROUGH SETTLING SOUTHWARD ACROSS THE NORTHEAST STATES.
ANOTHER STRONG SHORTWAVE WAS TRANSLATING EAST ACROSS NORTHERN
QUEBEC.

WE EXPECT THE HIGH CLOUDS TO PERSIST ACROSS SOUTHERN AREAS THROUGH
THIS MORNING...BEFORE THINNING FROM NW TO SE THIS AFTERNOON.
ELSEWHERE...PATCHY LOW CLOUDS WILL OCCASIONALLY PASS THROUGH THE
SOUTHERN ADIRONDACKS AND MOHAWK VALLEY REGION THIS MORNING.

THEN...FROM LATER THIS MORNING INTO THE AFTERNOON...WE EXPECT
SKIES TO VARY FROM PARTLY TO MOSTLY SUNNY...AS CU/STRATO-CU FORM.
THERE COULD BE A FEW BRIEF PERIODS OF MOSTLY CLOUDY SKIES IN THE
EARLY AFTERNOON ONCE CONVECTIVE TEMPS ARE REACHED...ESP ACROSS
HIGHER ELEVATIONS. EVENTUALLY...AS DRIER AIR SEEPS SOUTHWARD...WE
EXPECT THE AREAL COVERAGE OF CLOUDS TO DECREASE DURING THE LATE
AFTERNOON HOURS.

SOME MESOSCALE MODELS SUGGEST ISOLATED SHOWERS DEVELOP FROM THESE
CLOUDS...BUT MODEL SOUNDINGS SUGGEST STRONG CAPPING AND MID LEVEL
SUBSIDENCE DEVELOPING. SO...WILL KEEP OUT MENTION OF ANY SHOWERS
AT THIS TIME...BUT RADAR TRENDS WILL HAVE TO BE WATCHED...IN CASE
ANY OF THE BUILDING CU CAN GROW TALL ENOUGH AND PRODUCE ISOLATED
SHOWERS.

IT WILL BECOME BREEZY THIS AFTERNOON...AS 850-700 MB WINDS
STRENGTHEN BETWEEN AN APPROACHING TROUGH FROM THE NORTHWEST...AND
A LOW LEVEL RIDGE TO OUR SOUTHEAST. AS MIXING DEEPENS BY THIS
AFTERNOON...WEST TO NORTHWEST WINDS WILL DEVELOP AND INCREASE
INTO THE 10-20 MPH RANGE...WITH SOME GUSTS POSSIBLY REACHING UP TO
25 MPH AT TIMES THIS AFTERNOON WITHIN THE MOHAWK RIVER
VALLEY/CAPITAL REGION AND BERKSHIRES.

MAX TEMPS SHOULD REACH THE MID TO UPPER 80S IN MUCH OF THE HUDSON
RIVER VALLEY...PERHAPS NEARING 90 IN THE MID HUDSON VALLEY
ASSUMING THE HIGH CLOUDS DEPART SOON ENOUGH. ELSEWHERE...EXPECT
MAINLY LOWER/MID 80S IN VALLEYS...AND 75-80 ACROSS HIGHER
ELEVATIONS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
GENERALLY WARM WITH NO PRECIP EXPECTED THROUGH THIS PERIOD. THERE
COULD BE SOME PATCHY FOG LATE AT NIGHT THROUGH EARLY MORNING. MAX
TEMPS SHOULD REACH THE MID/UPPER 80S IN VALLEYS ON TUE...WITH
LOWER 80S FOR HIGHER ELEVATIONS...THEN SHOULD BE A FEW DEGREES
WARMER ON WED...REACHING AROUND 90 FOR VALLEYS...AND LOWER/MID 80S
ACROSS HIGHER TERRAIN. DEWPOINTS WILL REMAIN IN THE LOWER/MID
60S...GIVING HEAT INDICES OF 85-90 TUE...AND 90-95 ON WED.
OVERNIGHT MIN TEMPS SHOULD FALL INTO THE UPPER 50S TO LOWER
60S...WITH SLIGHTLY COOLER TEMPS POSSIBLE ACROSS PORTIONS OF THE
SOUTHERN ADIRONDACKS...AS WELL AS ACROSS PORTIONS OF SOUTHERN VT
AND WESTERN MA.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
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
LONG TERM PERIOD. MUCH OF THE PERIOD LOOKS TO BE VERY WARM TO HOT
WITH LITTLE IN THE WAY OF PRECIPITATION. ANY CONVECTION
THURSDAY...FRIDAY AND SUNDAY LOOKS TO BE MAINLY ISOLATED. THE
EXCEPTION WILL BE SOME SCATTERED CONVECTION ACROSS THE NORTHWEST
PORTION OF THE FA THURSDAY AS A LOW PRESSURE SYSTEM AND TRAILING
COLD FRONT MOVE ACROSS SOUTHEAST CANADA.

HIGHS EACH DAY WILL BE MAINLY IN THE 80S TO LOWER 90S...EXCEPT FOR
SOME UPPER 70S ACROSS TERRAIN ABOVE 2000 FEET. LOWS WILL GENERALLY
BE IN THE UPPER 50S TO MID 60S.

OVERALL TEMPERATURES WILL BE MUCH ABOVE NORMAL THURSDAY THROUGH
SUNDAY WITH PRECIPITATION BELOW NORMAL.

&&

.AVIATION /08Z MONDAY THROUGH FRIDAY/...

CLOUDS WILL GENERALLY DECREASE OVERNIGHT AS A DISTURBANCE MOVES
AWAY FROM OUR REGION. THIS COULD ALLOW FOR A PERIOD OF IFR FOG
LATE TONIGHT AT KPSF/GFL...ALTHOUGH IT WILL ULTIMATELY DEPEND ON
HOW QUICKLY THE CLOUDS DEPART. KALB/KPOU COULD SEE A BRIEF PERIOD
OF MVFR BR AROUND SUNRISE...OTHERWISE VFR CONDITIONS LOOK TO
CONTINUE AT THESE SITES. WINDS WILL BE CALM OVERNIGHT. ANY FOG
LOOKS TO DISSIPATE BY AROUND 12Z.

DURING THE DAY ON MONDAY...VFR CONDITIONS WILL BE IN PLACE FOR
ALL TAF SITES WITH SCT CIRRUS CLOUDS AROUND. SOME SCT CU MAY
DEVELOP BY AFTN...MAINLY OVER THE HIGH TERRAIN. SKIES WILL BECOME
SKC THIS EVENING WITH FOG DEVELOPING AT KGFL/KPSF AROUND 03Z.
LIGHT AND VARIABLE WINDS OVERNIGHT WILL BECOME W AT 8-15 KTS ON
MONDAY AND THEN BECOME LIGHT AND VARIABLE AGAIN MONDAY EVENING.

OUTLOOK...

TUESDAY NIGHT: NO OPERATIONAL IMPACT. NO SIG WX.
WEDNESDAY: NO OPERATIONAL IMPACT. NO SIG WX.
WEDNESDAY NIGHT: NO OPERATIONAL IMPACT. NO SIG WX.

OCCUR...ESP IN CLOSE PROXIMITY TO THE MOHAWK RIVER VALLEY/CAPITAL
