SYNOPSIS
DRIER CONDITIONS CAN BE EXPECTED TOMORROW AND MONDAY AS
THE COASTAL SYSTEM CURRENTLY IMPACTING THE REGION DEPARTS.
WIDESPREAD CHANCES FOR RAIN AND POSSIBLY SOME HIGH ELEVATION SNOW
INCREASE BEGINNING MONDAY NIGHT AS A FRONTAL SYSTEM APPROACHES THE
REGION. THE RETURN TO WET WEATHER TUESDAY AND PART OF WEDNESDAY WILL
YIELD GRADUALLY WARMING TEMPERATURES TO MORE SEASONABLE LEVELS WITH
ADDITIONAL CHANCES FOR PRECIPITATION LATE THIS WEEK INTO THE FIRST
HALF OF THE WEEKEND.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
UPDATE
RADAR AND WEBCAMS STILL INDICATING SOME BANDS OF
PRECIP ROTATING AROUND THE COASTAL STORM CENTERED OFFSHORE.
TRIED TO TIME POPS OVER THE NEXT FEW HOURS TO REFLECT CURRENT
RADAR TRENDS, WITH THE MOST CONCENTRATED ACTIVITY IN THE W.
ADIRONDACKS, W. MOHAWK VALLEY AND INTO THE TACONICS/BERKSHIRES.
MAINLY RAIN IS FALLING, ALTHOUGH SOME SNOW IS STILL POSSIBLE IN
THE COLDEST HIGHER TERRAIN SPOTS SOUTH/EAST OF ALBANY. ELSEWHERE
PATCHY DRIZZLE MAY OCCUR. TEMPERATURES ARE MAINLY IN THE MID
30S TO LOWER 40S EARLY THIS EVENING.
PREV DISCUSSION[0405]
THE COASTAL SYSTEM THAT HAS BEEN
IMPACTING EASTERN NEW YORK AND WESTERN NEW ENGLAND SINCE LAST
EVENING CONTINUES TO WEAKEN JUST EAST OF THE MID-ATLANTIC COAST
WITH A DRY SLOT EXTENDING NORTHWARD AND CONTINUING TO EXPAND
EAST AND WEST FARTHER ACROSS THE REGION. ACCORDING TO THE NYS
MESONET AND LOCAL METAR OBS, THE ONLY PLACES THAT HAVE NOT
WARMED PASSED FREEZING ARE LOCALIZED SPOTS OF THE EASTERN
CATSKILLS IN ULSTER AND GREENE COUNTIES. HERE, ACCORDING TO THE
KENX RADAR, A BATCH OF SNOW SHOWERS CONTINUES TO DIMINISH IN
SPATIAL COVERAGE AS IT TRIES TO EXIT TO THE WEST. THE CAMERAS AT
CLARYVILLE AND TANNERSVILLE SHOW LIGHT SNOW WITH 1-HOUR
ACCUMULATIONS LESS THAN 0.5". ADDITIONAL ACCUMULATIONS WITHIN
THE NEXT HOUR OR SO UNTIL IT FULLY EXITS WILL ALSO BE MINIMAL.
ELSEWHERE, SCATTERED RAIN SHOWERS REMAIN NORTH AND WEST OF THE
HUDSON RIVER VALLEY FOR THE MOST PART WITH NORTHEAST FLOW
ALLOWING THE RESPONSIBLE BAND OF MOISTURE ASSOCIATED WITH THE
LOW TO CONTINUE ITS DEPARTURE WESTWARD.
THROUGHOUT THE REST OF THE AFTERNOON AND THROUGHOUT TONIGHT, THE
COASTAL LOW WILL CONTINUE TO WEAKEN AS IT TRACKS ALMOST DUE
NORTHWARD TOWARDS CAPE COD. ONGOING SHOWERS WILL CONTINUE TO
TAPER OFF THROUGH THIS EVENING, THOUGH A FEW COULD LINGER INTO
TONIGHT ESPECIALLY IN LITCHFIELD AND THE LOWER MID-HUDSON
VALLEY, AS CYCLONIC FLOW KEEPS MOISTURE RELATIVELY CLOSE. BUT,
BY EARLY TOMORROW MORNING, DRY CONDITIONS SHOULD BE REINFORCED
REGIONWIDE AS THE LOW DRIFTS TOWARD THE GULF OF MAINE AND ITS
UPPER TROUGH TRAVERSES EASTWARD. CLOUDS WILL REMAIN PROMINENT
OVERNIGHT WITH DEEP-LAYER MOISTURE MAINTAINED BY AFOREMENTIONED
CYCLONIC FLOW SO LOW TEMPERATURES TONIGHT WILL FALL PRIMARILY
TO THE 30S WITH ISOLATED POCKETS OF UPPER 20S POSSIBLE AT
ELEVATIONS EXCEEDING 1000 FT.
SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/
THE UPPER-LEVEL TROUGH CONTINUES TO PUSH FARTHER EASTWARD AS ITS
ASSOCIATED COASTAL LOW TRACKS FARTHER NORTH, DEEPER INTO THE
GULF OF MAINE. THE LOW SHOULD REMAIN WELL OUT OF REACH SUCH THAT
THE DEVELOPMENT OF ADDITIONAL SHOWERS IS MITIGATED, BUT A LIGHT
RAIN SHOWER IN WESTERN NEW ENGLAND CAN'T BE RULED OUT TOMORROW
AFTERNOON IF THE LOW RETROGRADES TOWARD THE NEW ENGLAND COAST
MORE THAN CURRENTLY EXPECTED. SKIES WILL REMAIN MOSTLY CLOUDY
FOR MUCH OF THE DAY, THOUGH A GRADUAL DECREASE IS EXPECTED AS
THE LOW AND ITS ATTENDANT TROUGH ALOFT MOVE FARTHER OFF THE
COAST TOMORROW EVENING THROUGH TOMORROW NIGHT. HIGH TEMPERATURES
TOMORROW WILL THEREFORE REMAIN A BIT ON THE COOLER SIDE, THOUGH
CERTAINLY MORE MILD THAN TODAY WITH MID/UPPER 40S TO LOW 50S AND
POCKETS OF UPPER 30S TO LOW 40S ABOVE 1500 FT. LOW TEMPERATURES
TOMORROW NIGHT WILL THEN FALL TO THE UPPER 20S TO LOW 30S WITH
PARTLY CLOUDY TO MOSTLY CLEAR SKIES.
THOUGH CLOUDS WILL BE ON THE INCREASE AGAIN, MONDAY WILL
FINALLY BE A DAY TO SEE THE SUN AS SURFACE HIGH PRESSURE AND
SHORTWAVE RIDGING ALOFT BUILD FULLY IN ACROSS THE REGION. SKIES
WILL REMAIN PRIMARILY PARTLY CLOUDY WITH HIGH TEMPERATURES
FEELING MUCH MORE LIKE MID- APRIL, ACTUALLY JUST ABOVE MID-
APRIL STANDARDS, WITH VALUES IN THE 50S TO LOW 60S. HOWEVER, DRY
WEATHER WILL NOT BE LONG LASTING. BY MONDAY EVENING, A CLOSED
LOW PRESSURE SYSTEM WILL HAVE TRACKED JUST OVERHEAD THE NORTHERN
GREAT LAKES REGION WITH AN ASSOCIATED SURFACE CYCLONE AND
ATTENDANT WARM AND COLD FRONTS. AHEAD AND ALONG THE WARM FRONT,
WARM AIR ADVECTION AND ISENTROPIC LIFT WILL LEAD TO AN AREA OF
RAIN DEVELOPING AND MOVING INTO THE REGION BY LATE MONDAY
EVENING. BEING IN THE DIVERGENT ZONE OF THE CYCLONICALLY CURVED
UPPER JET, ENHANCED LIFT COULD LEAD TO SOME EMBEDDED HEAVIER
DOWNPOURS BUT THERE ARE NO HYDRO CONCERNS AT THIS TIME
ESPECIALLY SINCE THIS IS A FAIRLY PROGRESSIVE SYSTEM. THE
AFOREMENTIONED WARM FRONT LOOKS TO TRACK THROUGH THE REGION BY
EARLY TUESDAY MORNING WITH THE COLD FRONT SWIFTLY ON ITS HEELS.
LOW TEMPERATURES MONDAY NIGHT WILL BE IN THE UPPER 30S TO MID
40S SO NO SNOW OR MIXED PRECIPITATION IS EXPECTED AT THE ONSET
OF THIS SYSTEM.
LONG TERM /TUESDAY THROUGH SATURDAY/
KEY MESSAGE:
- THE EXTENDED FORECAST PERIOD WILL BRING WARMER, MORE SPRING-
LIKE TEMPERATURES AND A COUPLE CHANCES FOR PRECIPITATION.
DISCUSSION:
BY TUESDAY MORNING, THE AFOREMENTIONED CLOSED LOW
PRESSURE SYSTEM WILL HAVE MOVED OVERHEAD THE EASTERN GREAT
LAKES/WESTERN NEW YORK UPON HAVING SETTLED JUST SOUTH OF JAMES BAY.
SOME LIGHT SHOWERS WILL LINGER IN THE WAKE OF ITS PRIMARY COLD
FRONT BEFORE A DRY SLOT MOVES IN AND A SECOND ROUND OF PRECIPITATION
ACCOMPANIES ITS SECONDARY COLD FRONT THAT WILL CLEAR THE REGION BY
EARLY WEDNESDAY MORNING. ALL SHOWERS WILL BE IN THE FORM OF RAIN TO
START TUESDAY WITH HIGH TEMPERATURES REACHING THE MID/UPPER 40S TO
LOW 60 WITH POCKETS OF UPPER 30S TO LOW 40S AT THE HIGHEST
ELEVATIONS OF THE ADIRONDACKS. HOWEVER, WITH LOWS REACHING THE UPPER
20S TO UPPER 30S TUESDAY NIGHT, ADDITIONAL UPSLOPE AND CYCLONICALLY-
FORCED SHOWERS WILL LIKELY BE IN THE FORM OF SNOW, RAIN, OR A MIX
THEREOF.
LARGE SCALE TROUGHING REMAINS IN PLACE THROUGH WEDNESDAY
NIGHT/THURSDAY MORNING AS THE AFOREMENTIONED LOW SLOWLY TRACKS NORTH-
NORTHEAST INTO EASTERN QUEBEC. ADDITIONAL HIGH-ELEVATION, UPSLOPE
SNOW/RAIN SHOWERS CAN THEREFORE BE ANTICIPATED THROUGH WEDNESDAY
NIGHT BEFORE SHORTWAVE RIDGING BUILDS ACROSS THE NORTHEAST IN THE
WAKE OF THE DEPARTING TROUGH. HIGHS WEDNESDAY WILL BE THE COOLEST OF
THE EXTENDED PERIOD WITH 30S TO LOW 40S ACROSS HIGHER TERRAIN
REGIONS AND MID TO UPPER 40S TO NEAR 50 IN LARGER VALLEYS. LOWS
WEDNESDAY NIGHT WILL THEN FALL TO THE 20S AND 30S.
MID- TO UPPER-LEVEL, SHORTWAVE RIDGING BUILDING IN OVERTOP HIGH
PRESSURE AT THE SURFACE WILL REINFORCE DRY CONDITIONS THROUGH
THURSDAY WITH TEMPERATURES BEGINNING A WARMING TREND. HIGHS THURSDAY
WILL REACH THE 40S AND 50S WITH POCKETS OF UPPER 30S AT THE HIGHEST
ELEVATIONS OF THE SOUTHWEST ADIRONDACKS AND LOWS THURSDAY NIGHT
SIMILAR TO THOSE OF WEDNESDAY NIGHT. FRIDAY INTO THE FIRST HALF OF
THE WEEKEND THEN LOOK TO HOLD THE NEXT CHANCE FOR PRECIPITATION AS A
SURFACE LOW AND ASSOCIATED SHORTWAVE TROUGH TRAVERSE THE UPPER
MIDWEST AND APPROACH THE REGION. RAIN WILL SUBSEQUENTLY OVERSPREAD
THE REGION FROM WEST TO EAST BEGINNING AS EARLY AS FRIDAY AFTERNOON
AND LASTING THROUGH SATURDAY AS THE SYSTEM SLIDES OVERHEAD. HIGHS
FRIDAY WILL PRIMARILY BE IN THE 50S TO LOW 60S WITH MID/UPPER 40S AT
HIGHER ELEVATIONS AND LOWS FRIDAY NIGHT IN THE MID/UPPER 30S TO
UPPER 40S. SATURDAY WILL BE THE WARMEST DAY OF THE PERIOD WITH HIGHS
IN THE 50S TO MID/UPPER 60S WITH POCKETS OF UPPER 40S IN THE
SOUTHWEST ADIRONDACKS BEFORE LOWS DROP TO THE UPPER 20S TO LOW 40S.
