DISCUSSION
AS OF 229 PM EDT TUESDAY...
KEY MESSAGE 1: COOL, DRY, AND BREEZY CONDITIONS CONTINUE ACROSS THE
REGION THIS AFTERNOON WITH TEMPERATURES GENERALLY IN THE UPPER 40S
TO MID 50S. WEST TO NORTHWESTERLY WINDS CONTINUE TO BE BREEZY,
THOUGH NOT AS STRONG AS YESTERDAY. THESE WINDS WILL DROP OFF THIS
EVENING, WHICH WILL ALLOW FOR TEMPERATURES TO DROP THIS EVENING AS
IDEAL RADIATIONAL COOLING TAKES PLACE GIVEN THE DRY AIRMASS ACROSS
THE REGION. TEMPERATURES OVERNIGHT WILL GENERALLY DROP INTO THE 20S
AND 30S ACROSS THE REGION. A FROST ADVISORY REMAINS IN EFFECT FOR
THE CHAMPLAIN VALLEY, WHERE THE GROWING SEASON IS STILL ACTIVE. THE
BEST POTENTIAL FOR FROST DEVELOPMENT WILL BE EARLIER IN THE NIGHT,
WITH SOUTHERLY WINDS AND INCREASED CLOUD COVER PUTTING AN END TO
FROST POTENTIAL BY 5AM OR SO.
FOR TOMORROW, THE REGION WILL BE ON THE PERIPHERY OF A LOW CENTERED
OVER JAMES BAY, WITH AN ASSOCIATED WARM FRONT PASSING THROUGH MID-
DAY TOMORROW. TEMPERATURES TOMORROW WILL BE MUCH WARMER IN
COMPARISON TO THIS AFTERNOON, WITH DAYTIME HIGHS GENERALLY IN THE
UPPER 50S AND 60S. SOME LIGHT RAIN SHOWERS WILL BE POSSIBLE
THROUGHOUT THE DAY TOMORROW, PARTICULARLY IN THE AFTERNOON OR
EVENING BUT EXPECTED RAINFALL AMOUNTS WILL BE FAIRLY LIGHT.
ADDITIONAL SHOWER CHANCES WILL BE POSSIBLE THROUGH THE END OF THE
WORK WEEK AS A COLD FRONT MOVES THROUGH ON THURSDAY. THURSDAY LOOKS
LIKE IT COULD BE QUITE SIMILAR TO YESTERDAY, WITH MORE CONVECTIVE
SHOWERS DEVELOPING BEHIND THE FRONT AND THE POTENTIAL FOR SOME SMALL
HAIL AND/OR GRAUPEL.
KEY MESSAGE 2: LARGE RIDGING OVER THE MID-ATLANTIC STATES IS EXPECTED
TO ROLL EASTWARD SUPPORTING AN INCREASE IN RIDGING OVER THE
NORTHEAST. CONDITIONS WILL BE AROUND TO SLIGHTLY BELOW SEASONAL
AVERAGES FOR SATURDAY AS RIDGING KEEPS CONDITIONS DRY. SUNDAY, FLOW
IS FAVORED TO SHIFT MORE OUT OF THE SOUTH TO SOUTHWEST PROMOTING
WARM AIR ADVECTION AND TEMPERATURES WARMING ABOVE SEASONAL AVERAGES
INTO THE UPPER 60S TO AROUND 70 DEGREES. WINDS WILL LIKELY BE ON THE
RISE UNDER THIS PATTERN SHIFT FOR SUNDAY WITH GUSTS 15-20 MPH.
BEYOND SUNDAY, THE HIGH IS FAVORED TO REMAIN PROGRESSIVE WITH A
SOUTHERN TRAJECTORY LOW PRESSURE SYSTEM POTENTIALLY RIDING UP THE
BACKSIDE OF THE RIDGE. THIS LOW COULD BE THE REMNANTS OF A TROPICAL
SYSTEM OUT OF THE GULF WATERS OFF TEXAS AND LOUISIANA. HOWEVER,
MODELS TEND TO BE TOO PROGRESSIVE WITH THESE FEATURES AT THIS TIME
SCALE, SO IT'S MORE LIKELY THAT THIS LOW WILL BE DELAYED LONGER. IF
SO, A NORTHERN STREAM TROUGH WILL SWEEP THROUGH. EITHER WAY, SOME
PRECIPITATION CHANCES ARE POSSIBLE.
AVIATION /18Z TUESDAY THROUGH SUNDAY/
THROUGH 18Z WEDNESDAY...VFR CONDITIONS ARE EXPECTED TO PREVAIL
THROUGH THE FORECAST PERIOD. THE MAIN AVIATION CHALLENGES WILL
BE GUSTS 15-20KTS OUT OF THE WEST THIS AFTERNOON, WINDS
SWITCHING SOUTH AFTER 12Z WITH MORE GUSTS 15-20KTS IN GENERAL,
AND SOME POTENTIAL FOR LIGHT SHOWERS AFTER 12Z WEDNESDAY IN
PORTIONS OF NORTHERN NEW YORK. PBG COULD SEE HIGHER GUSTS TO
AROUND 25KTS WITH WINDS COMING OFF OF LAKE CHAMPLAIN TOMORROW.
