SYNOPSIS
BEAUTIFUL SPRING-LIKE CONDITIONS TODAY WILL GIVE WAY TO
SCATTERED, LIGHT SHOWERS TONIGHT INTO TOMORROW COURTESY OF A PASSING
DISTURBANCE. WIDESPREAD RAIN AND COOL TEMPERATURES ARE ANTICIPATED
ONCE AGAIN FOR THIS WEEKEND WITH DRY CONDITIONS AND A GRADUAL WARM
UP ANTICIPATED EARLY NEXT WEEK.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
TRANQUILITY PERSISTS ACROSS EASTERN NEW YORK AND WESTERN NEW
ENGLAND THIS AFTERNOON AS DRY AIR AND SUBSIDENCE FROM AN
ADJACENT SURFACE HIGH CONTINUE TO TRIUMPH OVER MOIST,
SOUTHEASTERLY FLOW ON THE EASTERN FLANK OF A CLOSED LOW IN THE
UPPER MIDWEST/WESTERN OHIO VALLEY. A SHORTWAVE DISTURBANCE ROTATING
THROUGH THIS SYSTEM WILL NEAR THE REGION THIS AFTERNOON/EVENING,
PAIRING WITH AN ASSOCIATED SURFACE TROUGH TO ENHANCE CONVERGENCE
AND UVVS SUCH THAT THE COLUMN WILL MOISTEN AND SHOWERS FINALLY
REACH THE SURFACE BY TONIGHT. HOWEVER, MEASURABLE PRECIPITATION
WILL BE MOST LIKELY IN UPSLOPE REGIONS OF THE EASTERN
CATSKILLS, SOUTHWEST ADIRONDACKS, AND SOUTHERN GREENS THROUGHOUT
THE NIGHT AS OROGRAPHIC ENHANCEMENT WILL HELP TO FURTHER
OVERCOME DRIER LOW-LEVELS. STILL, NUISANCE SHOWERS WILL BE
POSSIBLE ALMOST EVERYWHERE TONIGHT WITH LOW TEMPERATURES IN THE
UPPER 40S TO LOW 50S.
SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/
NUISANCE SHOWERS CONTINUE INTO THURSDAY AS THE ONCE SURFACE WAVE
DEEPENS INTO A WEAK LOW JUST OFF THE MID-ATLANTIC COAST AND THE
CLOSED LOW CONVERSELY WEAKENS INTO AN OPEN TROUGH ALOFT. WITH
LITTLE IN THE WAY OF MOISTURE, VERY LITTLE ACCUMULATION CAN BE
ANTICIPATED WITH SHOWERS HIGHLY SCATTERED IN NATURE AS BOTH THE
SURFACE LOW AND UPPER TROUGH TRACK NORTH AND EAST THROUGHOUT THE
DAY. CLOUDY AND RAIN-COOLED AIR WILL MAKE FOR HIGHS THAT ARE A
BIT COOLER THAN TODAY WITH VALUES GENERALLY IN THE UPPER 50S
ACROSS HIGHER ELEVATIONS TO UPPER 60S IN LARGE VALLEY AREAS. A
BRIEF RESPITE IN PRECIPITATION COMES THURSDAY NIGHT INTO FRIDAY
BEFORE OUR NEXT WEATHER PRODUCER EXPECTED FOR FRIDAY NIGHT
THROUGH SATURDAY. LOWS THURSDAY NIGHT WILL FALL TO THE UPPER 40S
IN THE SOUTHWEST ADIRONDACKS TO MID 50S ELSEWHERE. HIGHS FRIDAY
WILL BE IN THE 60S AND 70S.
WIDESPREAD RAINFALL IS THEN EXPECTED FRIDAY NIGHT INTO SATURDAY,
THOUGH BASED ON LATEST GUIDANCE THIS AFTERNOON, IT IS CLEAR THAT
THERE IS STILL A FAIR AMOUNT OF UNCERTAINTY WITH THIS FORECAST.
GENERAL CONSENSUS SHOWS A SYSTEM REPRESENTATIVE OF A NEUTRAL-
TILT, "TYPE A" WARM SEASON NOR'EASTER BRINGING 0.5" TO LOCALIZED
1.5" THROUGH SUNDAY MORNING. HOWEVER, LATEST RUNS HAVE INDICATED
MORE OF A LACK OF PHASING OF THE PRIMARY, CLOSED UPPER LOW AND
A SHORTWAVE ROTATING ABOUT ITS SOUTHERN PERIPHERY WHICH
DISPLACES THE DEVELOPING SURFACE COASTAL LOW FARTHER TO THE
SOUTH AND EAST. THIS WOULD INEVITABLY SHIFT THE AXIS OF HEAVIEST
RAIN TO THE EAST AND MAY PROMOTE THE ENTRAINMENT OF DRY AIR INTO
OUR REGION, ULTIMATELY GIVING US MUCH LESS RAIN THAN THE CURRENT
FORECAST WOULD SUGGEST. REGARDLESS, THIS WOULD BE A BENEFICIAL
SOAKING RAIN THAT POSES LITTLE TO NO HYDROLOGICAL CONCERNS. LOWS
FRIDAY NIGHT WILL BE SIMILAR TO THOSE OF THURSDAY NIGHT WITH
HIGHS SATURDAY SIMILAR TO THOSE OF FRIDAY.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
RESIDUAL RAIN FROM SATURDAY'S NOR'EASTER WILL MAKE FOR A WET
START TO THE LONG TERM FORECAST PERIOD AS MOIST, CYCLONIC FLOW
DOMINATES BENEATH THE NORTHEAST-DEPARTING SYSTEM. BY THIS POINT,
HOWEVER, THE BULK OF THE RAIN WILL HAVE ALREADY FALLEN SO
ADDITIONAL PRECIPITATION WILL BE LIGHT. LINGERING SHOWERS WILL
PERSIST INTO THE DAY SUNDAY, ESPECIALLY FOR UPSLOPE AND LAKE-
ADJACENT HIGH TERRAIN AREAS GIVEN THE STALL OF THE UPPER LOW
OVERHEAD. HOWEVER, BY SUNDAY NIGHT THE SYSTEM FINALLY SHIFTS
FARTHER TO THE NORTHEAST WITH HIGH PRESSURE BUILDING IN AT THE
SURFACE TO REINFORCE DRY CONDITIONS REGIONWIDE. BROAD TROUGHING
PERSISTING ALOFT SHOULD KEEP SKIES AT LEAST PARTLY CLOUDY
THROUGH MONDAY MORNING, BUT AS UPPER-LEVEL RIDGING BUILDS
EASTWARD ACROSS THE REGION BEGINNING MONDAY NIGHT, MAINLY CLEAR
SKIES WILL JOIN DRY SURFACE CONDITIONS TO BRING A MUCH NEEDED
REPRIEVE FROM DREARY WEATHER.
TEMPERATURES THROUGHOUT THE EXTENDED PERIOD WILL BEGIN ON THE
CHILLY SIDE BY EARLY JUNE STANDARDS WITH HIGHS IN THE 50S ACROSS
HIGHER TERRAIN AND 60S IN THE VALLEYS. BUT WITH A GRADUAL
WARMING TREND, HIGHS WILL MODERATE INTO THE UPPER 60S TO UPPER
70S BY TUESDAY. LOWS THROUGHOUT THE PERIOD WILL BEGIN IN THE 40S
BEFORE GRADUALLY MODERATING TO THE 50S.
AVIATION /20Z WEDNESDAY THROUGH MONDAY/
THROUGH 18Z THURSDAY...VFR CONDITIONS WILL PREVAIL THROUGH AT LEAST
THE FIRST 6 HOURS OF THE FORECAST TODAY. THEN CONDITIONS WILL
GRADUALLY DETERIORATE LATER THIS EVENING INTO THE OVERNIGHT HOURS,
AS A LOW PRESSURE SYSTEM APPROACHES FROM THE SOUTH. THE SYSTEM WILL
ALSO BE WEAKENING AS IT MOVES IN, SO ONLY SITE WHERE PREVAILING
SHOWERS WILL BE MENTION IS AT KPOU, WITH SEVERAL PROB30 GROUPS AT
KALB/KGFL/KPSF TO ACCOUNT FOR LOWER CHANCES AND SCATTERED COVERAGE
OF SHOWERS. CONDITIONS WILL GRADUALLY DETERIORATE TO MVFR INITIALLY,
WITH IFR EXPECTED BY EARLY THURSDAY MORNING AT ALL TAF SITES. IFR
CONDITIONS ARE THEN EXPECTED TO PREVAIL THROUGH 18Z THURSDAY WITH A
FEW MORE SHOWERS. WINDS WILL BE SOUTHERLY AROUND 5-10 KT BECOMING
SOUTHEAST AROUND 2-6 KT TONIGHT.
