NATIONAL WEATHER SERVICE ALBANY NY
230 PM EDT THU APR 30 2026
WHAT HAS CHANGED
WIDELY SCATTERED SHOWERS INTRODUCED FRIDAY NIGHT FROM AROUND
I-90 SOUTH ASSOCIATED WITH A DISTURBANCE. LESSER CHANCES FOR
FROST FRIDAY AND SATURDAY NIGHT EXCEPT FOR ACROSS THE UPPER
HUDSON VALLEY. POPS INCREASED TO 30% SOUTH/EAST OF ALBANY
SATURDAY AFTERNOON/EVENING DUE TO AN OCEAN STORM TRENDING
SLIGHTLY FARTHER NORTH COMPARED TO PRIOR FORECASTS. THE BULK OF
ANY WIDESPREAD RAINFALL FROM THIS SYSTEM STILL LOOKS TO REMAIN
WELL SOUTH/EAST OF OUR AREA.
KEY MESSAGES
1) WIDESPREAD RAIN TAPERS OFF FROM WEST TO EAST THIS MORNING,
ALTHOUGH SCATTERED TO NUMEROUS SHOWERS WILL LINGER INTO THIS
AFTERNOON.
2) HIGH CONFIDENCE IN BELOW NORMAL TEMPERATURES THROUGH THIS
WEEKEND. FROST ADVISORIES MAY BE NEEDED FOR PORTIONS OF THE HUDSON
VALLEY, SOUTHERN TACONICS AND LITCHFIELD HILLS WHERE THE GROWING
SEASON BEGINS MAY 1.
3) UNSETTLED PATTERN EXPECTED TO DEVELOP, WITH MULTIPLE
OPPORTUNITIES FOR RAINFALL MONDAY THROUGH WEDNESDAY.
DISCUSSION
KEY MESSAGE 1...
WIDESPREAD RAIN WILL TAPER OFF FROM WEST TO EAST THIS MORNING,
AS A DUAL CYCLONE SYSTEM TRACKS EAST OF THE AREA. WITH AN UPPER
LEVEL TROUGH SETTLING IN TODAY, THERE WILL BE ADDITIONAL
SCATTERED TO NUMEROUS SHOWERS THROUGH MUCH OF THE DAY. THE
GREATEST COVERAGE IS EXPECTED TO BE FOR AREAS NORTH/EAST OF
ALBANY AS A SHORT WAVE PIVOTS THROUGH. IT WILL BE MOSTLY CLOUDY
AND COOL WITH WINDS SHIFTING TO THE W-NW AND GUSTING AROUND 20
MPH IN THE MOHAWK VALLEY AND CAPITAL DISTRICT THIS AFTERNOON.
HIGHS TODAY WILL BE MUCH COOLER THAN RECENT DAYS, RANGING FROM
THE UPPER 40S TO AROUND 60.
KEY MESSAGE 2...
A LARGE SCALE UPPER LEVEL TROUGH WILL TAKE RESIDENCE ACROSS THE
GREAT LAKES AND NORTHEAST THROUGH THE UPCOMING WEEKEND. THE
CORE OF THE UPPER LOW IS EXPECTED TO GRADUALLY TRACK EAST FROM
SOUTHERN ONTARIO TODAY INTO SOUTHERN QUEBEC FRI/SAT. THIS
PATTERN WILL RESULT IN BELOW NORMAL TEMPERTURES, WITH PERSISTENT
850 MB TEMPERATURE ANOMALIES OF -1 TO -2 STDEV. TEMPERATURES DO
NOT LOOK QUITE COOL ENOUGH FOR ANY FROST TONIGHT, BUT MAY BE
MORE CONDUCIVE OVER THE WEEKEND ESPECIALLY NORTH OF ALBANY. WITH
AN EXPECTED DISTURBANCE MOVING THROUGH THE SOUTHERN HALF OF THE
AREA FRI NIGHT AND CLOUDS ALONG THE NORTHERN PERIPHERY OF AN
OCEAN STORM SAT NIGHT, CHANCES FOR FROST HAVE LOWERED FROM THE
CAPITAL DISTRICT SOUTH. HOWEVER, SCATTERED FROST MAY DEVELOP
ACROSS THE UPPER HUDSON VALLEY BOTH FRI NIGHT AND SAT NIGHT, SO
FROST ADVISORIES MAY EVENTUALLY BE NEEDED FOR THE UPPER HUDSON
VALLEY. THE GROWING SEASON BEGINS MAY 1 FOR THE HUDSON VALLEY,
S. TACONICS AND LITCHFIELD HILLS. BOTH HIGH AND LOW TEMPERATURES
ARE EXPECTED TO BE AROUND 5-10 DEGREES BELOW NORMAL TODAY
THROUGH THE WEEKEND.
KEY MESSAGE 3...
AN UNSETTLED PATTERN IS SHAPING UP FOR THE EARLY TO MIDDLE OF
NEXT WEEK, WITH TEMPERATURES WARMING BACK TO NORMAL LEVELS. BY
MON, THE UPPER LEVEL PATTERN IS EXPECTED TO BECOME MORE ZONAL,
WITH SOME AMPLIFICATION TUE INTO WED. THERE WILL BE MULTIPLE
OPPORTUNITIES FOR RAINFALL, FIRST WITH A FRONTAL SYSTEM MOVING
THROUGH MON INTO TUE, THEN POTENTIALLY MORE SUBSTANTIALLY WITH A
WAVE OF LOW PRESSURE DEVELOPING ALONG OR NORTH A FRONT ON WED.
MOST SOURCES OF DETERMINISTIC AND ENSEMBLE GUIDANCE ARE NOW
INDICATING A CYCLONE IN VICINITY OF THE REGION WITH
STRENGTHENING SOUTHERLY FLOW SUPPLYING AMPLE MOISTURE. WILL
CONTINUE TO MONITOR TRENDS FOR POSSIBLE HEAVY RAINFALL WED INTO
THU. SHOULD THE CYCLONE TRACK NORTH OF OUR AREA, THEN
THUNDERSTORMS COULD OCCUR WITHIN ANY WARM SECTOR.
