DISCUSSION
KEY MESSAGE 1...
ISOLATED TO SCATTERED SHOWERS ARE EXPECTED THIS AFTERNOON INTO
TONIGHT, MAINLY ACROSS HIGHER TERRAIN AREAS, AS AN UPPER- LEVEL
SHORTWAVE ROTATES THROUGH THE REGION ABOUT THE WESTERN
PERIPHERY OF AN EASTWARD- DEPARTING LOW. WITH LIMITED MOISTURE
AND FORCING FOR ASCENT, ALL SHOWERS ARE ANTICIPATED TO BE LIGHT
AND BRIEF. ADDITIONALLY, AN OVERALL LACK OF INSTABILITY SHOULD
LIMIT VERTICAL GROWTH AND LARGELY MITIGATE THE DEVELOPMENT OF
THUNDERSTORMS. HOWEVER, AN ISOLATED RUMBLE OR TWO CANNOT BE
RULED OUT.
THE PASSAGE OF A SECOND SHORTWAVE TONIGHT INTO TOMORROW WILL
LEAD TO LINGERING SHOWERS THROUGH ABOUT MID TO LATE MORNING.
LATEST CAMS INDICATE SOME OF THESE DRIFTING INTO THE MID-HUDSON
VALLEY AND SOUTHWEST NEW ENGLAND, SO SLIGHT CHANCE TO CHANCE
POPS WERE ADDED IN THOSE LOCATIONS. HOWEVER, BY EARLY TOMORROW
AFTERNOON, SHOWERS WILL BE SCOURED OUT BY THE DEPARTURE OF THE
AFOREMENTIONED SHORTWAVE AND THE BUILDING IN OF HIGH PRESSURE.
REGIONWIDE DRY CONDITIONS WILL THEN REMAIN IN PLACE THROUGH
TUESDAY AS HIGH PRESSURE DOMINATES.
CHANCES FOR MORE WIDESPREAD SHOWERS RETURN WEDNESDAY INTO
THURSDAY AS A FRONTAL SYSTEM APPROACHES OVERHEAD FROM THE WEST.
WHILE THE BEST FORCING LOOKS TO STAY WELL TO OUR NORTH, GUIDANCE
CONTINUES TO SUPPORT THE EXPECTATION FOR BENEFICIAL RAIN FOR
AREAS ALONG AND NORTH OF I-90. THERE ARE MEDIUM TO HIGH CHANCES
(~40-80%) FOR AT LEAST 0.25" OF RAIN IN THESE AREAS WITH LOW
CHANCES (~ 30% OR LESS) ELSEWHERE. AT THIS TIME, THERE NOT ONLY
REMAINS LOW CONFIDENCE IN SEVERE THUNDERSTORM POTENTIAL, BUT THE
OVERALL POTENTIAL FOR THUNDERSTORMS. PROBABILISTIC GUIDANCE IS
INDICATING LOW PROBABILITIES OF THUNDER WITH DETERMINISTIC
MODELS SUPPORTING THAT SOLUTION WITH VERY LIMITED INSTABILITY ON
BOTH DAYS. HOWEVER, WE WILL KEEP A CLOSE EYE ON TRENDS IN THE
COMING DAYS AND REPORT ANY CHANGES.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THROUGH 00Z/MON...VFR CONDITIONS BEGIN THE TAF PERIOD AND SHOULD
STAY VFR INTO THE OVERNIGHT HOURS. AN ADDITIONAL UPPER SHORTWAVE
WILL PASS THROUGH THE AREA LATER OVERNIGHT INTO SUNDAY MORNING
WHICH COULD LEAD TO CIGS LOWING INTO THE MVFR RANGE AT SOME
SITES ALONG WITH SOME RAIN SHOWERS WITH MVFR VSBYS. PROB30
GROUPS WERE INCLUDED FOR THIS POSSIBILITY. IN THE WAKE OF THIS
SHORTWAVE, FLIGHT CONDITIONS WILL RETURN TO VFR WITH DRY WEATHER
FOR THE REST OF SUNDAY. WINDS WILL BE MAINLY OUT OF THE NORTH TO
NORTHWEST AT 5 KT OR LESS TONIGHT, THEN 5-10 KT SUNDAY.
