REGION EARLY THIS MORNING, ENDING THE THREAT FOR SEVERE
THUNDERSTORMS AND FLOODING. WITH CLEARING EXPECTED DURING THE

RAINFALL ON THURSDAY.

THREAT FOR RAINFALL RETURNS DURING THE EARLY TO MIDDLE PART OF
NEXT WEEK. WPC HAS THE REGION IN A MARGINAL RISK FOR EXCESSIVE
RAINFALL FOR MONDAY INTO MONDAY NIGHT (DAY 4) AND ALSO FOR
TUESDAY INTO TUESDAY NIGHT (DAY 5).

AGAIN TODAY FOR SOUTHERN AND EASTERN AREAS, BUT NO ADDITIONAL

DISCUSSION
KEY MESSAGE 1...
AS ANTICIPATED, SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
ON THURSDAY AFTERNOON AND EVENING RESULTED IN SOME REPORTS OF
WIND DAMAGE AND HEAVY RAINFALL. A STORM SURVEY WILL TAKE PLACE
TODAY (FRIDAY) TO SEE IF TORNADIC DAMAGE OCCURRED IN THE WILTON
AREA OF SARATOGA COUNTY. WITH THE LOSS OF DAYTIME HEATING,
SHOWERS AND THUNDERSTORMS DIMINISHED OVERNIGHT, ALTHOUGH OUR
REGION REMAINS IN A WARM AND HUMID AIR MASS AHEAD OF A SURFACE
COLD FRONT.
THE SURFACE COLD FRONT IS CURRENTLY LOCATED OVER WEST-CENTRAL
NEW YORK AND IT WILL BE SLOWLY MAKING ITS WAY EASTWARD FOR
TODAY. WHILE IT LOOKS TO CROSS THE FORECAST AREA THIS MORNING,
IT MAY STALL CLOSE TO OR JUST EAST OF THE AREA ACROSS NEW
ENGLAND FOR DURING THE DAY TODAY, BEFORE SHIFTING OFFSHORE FOR
TONIGHT, AS A WEAK WAVE OF LOW PRESSURE MOVES ALONG THE
BOUNDARY. BEHIND THE COLD FRONT, WINDS WILL SWITCH TO THE WEST
AND SOME DRIER AIR WILL START WORKING INTO THE DAY, BUT IT WILL
PROBABLY TAKE UNTIL TONIGHT OR TOMORROW TO SEE A NOTICEABLE DROP
IN THE DEWPOINTS. TEMPS WILL REMAIN FAIRLY SEASONABLE WITH HIGHS
IN THE MID 70S TO LOW 80S.
BASED OFF THE LATEST CAMS, SOME ISOLATED SHOWERS OR THUNDERSTORMS
LOOK TO DEVELOP TODAY, MAINLY FOR SOUTHERN AND EASTERN AREAS.
COVERAGE LOOKS MUCH LOWER COMPARED TO THURSDAY AND STORMS WILL
BE FAIRLY ISOLATED IN COVERAGE. WITH THE FRONT COMING THROUGH,
THERE WON'T BE AS MUCH INSTABILITY TODAY COMPARED TO YESTERDAY.
WHILE THERE MAY BE ENOUGH SBCAPE AVAILABLE FOR A FEW RUMBLES OF
THUNDER, THERE'S NO THREAT FOR SEVERE STORMS TODAY AND 0-6 KM
BULK SHEAR WILL GENERALLY BE UNDER 20 KTS. WITH THE ISOLATED
COVERAGE OF STORMS AND BRIEF NATURE OF ANY PRECIP, THERE'S NO
THREAT FOR ANY FLOODING TODAY AS WELL. ANY PRECIP LOOKS TO BE
DONE BY THE LATE AFTERNOON OR EARLY EVENING HOURS.
KEY MESSAGE 2...
AS HIGH PRESSURE BUILDS ACROSS THE REGION, DRY AND PLEASANT
WEATHER IS EXPECTED FOR SATURDAY. SKIES WILL BE FAIRLY SUNNY AND
DEWPOINTS WILL BE COMFORTABLE, WITH VALUES GENERALLY IN THE 50S.
HIGHS WILL BE SEASONABLE, WITH VALLEY AREAS IN THE UPPER 70S TO
NEAR 80 IN THE AFTERNOON HOURS. OVERNIGHT LOWS LOOK COMFORTABLE
IN THE 50S (SOME 40S FOR THE HIGH TERRAIN) FOR SATURDAY NIGHT.
ALTHOUGH TEMPS AND DEWPOINTS LOOK SLIGHTLY HIGHER FOR SUNDAY, IT
WILL BE CONTINUED DRY WITH A PARTLY CLOUDY SKY.
THE NEXT CHANCE FOR PRECIPITATION LOOKS TO BE DURING THE EARLY
TO MIDDLE PART OF NEXT WEEK AS AN ACTIVE PATTERN LOOKS TO SET UP
ACROSS THE REGION. A LARGE UPPER LEVEL RIDGE WILL ESTABLISH
ITSELF ACROSS THE CENTRAL AND EASTERN PART OF THE CONUS, BUT OUR
AREA WILL BE ON THE NORTHERN FRINGE OF THIS RIDGING. AS A
RESULT, A SERIES OF DISTURBANCES WILL BE RIDING ACROSS THE TOP
OF THE UPPER LEVEL RIDGE FOR MONDAY THROUGH WEDNESDAY AND WILL
BRING A FEW CHANCES FOR SHOWERS AND THUNDERSTORMS, AS SEVERAL
SYSTEMS DIVE TOWARDS THE AREA WITHIN THE WEST TO NORTHWEST FLOW
ALOFT.
THE LATEST NBM SHOWS ABOUT A 50% CHANCE OF SEEING AN INCH OR
MORE OF PRECIPITATION FOR MONDAY THROUGH WEDNESDAY, WITH ABOUT A
15-25% CHANCE FOR 2". WHILE THESE DON'T APPEAR TO BE HIGH
PROBABILITIES AT FIRST GLANCE, IT'S A SIGNAL WORTH NOTING
CONSIDERING IT'S STILL DAYS 4-6 AND CONVECTIVE RAINFALL TOTALS
CAN BE HARD FOR LARGE-SCALE GUIDANCE TO PREDICT THIS FAR OUT IN
TIME. WPC HAS A MARGINAL RISK FOR EXCESSIVE RAINFALL FOR
MON/MON NIGHT AND ALSO TUES/TUES NIGHT AND THIS MAKES SENSES
CONSIDERING THE PATTERN THAT WILL BE IN PLACE.
