40S EXPECTED.

HIPRES BUILDS IN FM THE WEST BY AFTN WITH SKIES CLRNG RAPIDLY AFT
18Z. DRIER AIR ACCOMPANIES HIPRES, ALLOWING TEMPS TO WARM INTO THE
M/U 50S THRU THE DAY. BRIEF S/WV RIDGING WL OCCUR AT UPR LVLS WITH
HGTS ON THE RISE.

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
340 PM UPDATE...
FORECAST ADJUSTED SLIGHTLY TO ACCOUNT FOR LATEST WPC GUIDANCE.
UNLIKE THE UPPER LOW CURRENTLY IMPACTING THE REGION...THE ONE
PASSING THIS WEEKEND WILL BE MOVING ALONG QUICKLY...FROM JAMES
BAY SATURDAY NIGHT TO NORTHERN MAINE ALREADY BY SUNDAY EVENING AND
ZIPPING AWAY FROM THERE. THERE WILL BE SOME SHOWERS SUNDAY NORTH
OF THE TWIN TIERS...BUT WNW WINDS AND BRIEF PERIOD OF COLD AIR
ADVECTION MAY ALSO ALLOW FOR LAKE ENHANCEMENT NORTH OF THE
THRUWAY. 850MB TEMPERATURES ARE PROJECTED TO REACH NEAR OR EVEN
SLIGHTLY BELOW ZERO CELSIUS...WHICH SHOULD BE ENOUGH FOR SOME LAKE
RESPONSE GIVEN WATER TEMPERATURES STILL IN LOWER TEENS CELSIUS.
ONE OTHER ADJUSTMENT WAS TO DELAY THE NEXT CHANCE OF RAIN AFTER
THE WEEKEND TO WEDNESDAY BASED ON LATEST GUIDANCE AND MODELS. SO
NOW BOTH MONDAY AND TUESDAY LOOK DRY...WITH MODERATING
TEMPERATURES.

PREVIOUS DISCUSSION...
CLOSELY FOLLOWED WPC GUIDANCE.

LOOKS LIKE FALL HAS RETURNED TO NY AND PA. AN UNSETTLED WEATHER
PATTERN IS EXPECTED ACROSS THE NORTHEAST AT THE START OF THE
FORECAST PERIOD AS ANOTHER UPPR LVL LOW IS EXPECTED TO SWING
THROUGH THE REGION. RAIN SHOWERS ARE POSSIBLE THROUGH THE WEEKEND
FROM THIS SYSTEM. HIGH PRESSURE WILL THEN START TO BRIEFLY BUILD
OVER THE AREA ON MONDAY... BUT QUICKLY MOVE OUT FROM THE CWA ON
TUESDAY. ANOTHER SYSTEM WILL THEN START TO IMPACT THE REGION
TUESDAY AFTERNOON/EVENING BRINGING ANOTHER SHOT OF SHOWERS ACROSS
THE AREA.

SUNDAY WILL FEEL LIKE FALL AS TEMPS WILL RISE INTO THE UPPR 50S
TO LOW 60S ACROSS THE AREA. MONDAY MORNING WILL BE FAIRLY CHILLY WITH
TEMPS FALLING INTO THE MID TO UPPR 30S. WAA WILL START TO OCCUR
OVER THE REGION MONDAY EVENING... WHICH WILL RESULT IN TEMPS
REMAINING IN THE 40S IN THE MORNINGS AND HIGHS IN THE 60S TUES AND
WED.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
ANOTHER COMPLEX AND DIFFICULT FORECAST IS EXPECTED THROUGH THE
FORECAST PERIOD. A LARGE AND SLOW MOVING LOW PRESSURE SYSTEM IS
LOCATED JUST OFF THE EAST COAST THIS AFTERNOON. THIS SYSTEM WILL
CREATE FLIGHT RESTRICTIONS ACROSS THE AREA AGAIN TODAY AND
TONIGHT AS IT MOVES NORTH TOWARDS CANADA. AS THE SYSTEM MOVES NORTH
IT WILL ALSO BRING THE CHANCE FOR RAIN SHOWERS ACROSS CENTRAL NY
AND NORTHEAST PA. VISBYS MAY FALL TO AROUND 3SM WITH THE HEAVIER
SHOWERS. EXPECT CIGS TO REMAIN MOSTLY AT MVFR THROUGH FRIDAY
MORNING. FRIDAY MORNING DRY AIR WILL START TO PUSH IN RESULTING IN
SKIES CLEARING OUT. THERE IS UNCERTAINTY TIMING OF THIS CLEARING
OUT ON FRIDAY MORNING. TRIED TO PLACE THE BEST TIMING ON THE
CLEARING BUT MAY HAVE TO ADJUST WHEN MOSTLY CLEAR SKIES WILL
RETURN.

WINDS WILL REMAIN GUSTY THROUGH THE AFTERNOON WITH GUSTS UP TO
AROUND 20 KNOTS. WINDS WILL SETTLE BELOW 12 KNOTS AFTER SUNSET.
