NATIONAL WEATHER SERVICE ALBANY NY
206 PM EDT FRI MAY 1 2026
WHAT HAS CHANGED
HAVE INCREASED POPS FURTHER FOR TONIGHT WITH WIDESPREAD 60-90%
CHANCE FOR RAIN OVERNIGHT FOR MUCH OF THE REGION.
WITH DECENT CLEARING EXPECTED ON SATURDAY, OVERNIGHT LOWS WILL
BE IN THE 20S AND 30S ON SATURDAY NIGHT. THE GROWING SEASON HAS
BEGUN IN THE HUDSON VALLEY AND NW CT, SO HAVE INCLUDED FROST FOR
AREAS WHERE MINIMUM TEMPERATURES WILL BE 36 DEGREES OR LESS
(MAINLY UPPER HUDSON VALLEY).
HAVE LOWERED DEWPOINTS AND INCREASED WIND GUSTS ON SUNDAY
AFTERNOON, AS STRONG PRESSURE GRADIENT AND GOOD MIXING WILL
RESULT IN A DRY AND WINDY DAY. THIS WILL RESULT IN THE POTENTIAL
FOR ELEVATED FIRE WEATHER CONDITIONS.
KEY MESSAGES
1) BELOW NORMAL TEMPERATURES WILL CONTINUE THROUGH THIS
WEEKEND. TEMPERATURES MAY BE COLD ENOUGH FOR FROST ON SATURDAY
NIGHT AND SUNDAY NIGHT FOR SOME PARTS OF THE AREA WHERE THE
GROWING SEASON HAS ALREADY BEGUN.
2) DEPENDING ON FUEL AVAILABILITY, RED FLAG CONDITIONS WILL
LIKELY BE MET ON SUNDAY DUE TO GUSTY WINDS AND LOW RELATIVE
HUMIDITY VALUES FOR MUCH OF THE REGION.
3) UNSETTLED PATTERN IS EXPECTED NEXT WEEK WITH THE POTENTIAL
FOR BOTH HEAVY RAINFALL AND STRONG THUNDERSTORMS DURING THE MID
WEEK.
DISCUSSION
KEY MESSAGE 1...
A LARGE UPPER LEVEL TROUGH WILL BE LOCATED OVER THE NORTHEAST
THIS WEEKEND. THE COOLER TEMPS ALOFT AND CYCLONIC FLOW WILL
ALLOW FOR TEMPERATURES TO REMAIN BELOW NORMAL, FOR BOTH DAYTIME
HIGHS AND OVERNIGHT LOWS.
A FAST MOVING UPPER LEVEL DISTURBANCE ROTATING AROUND THE UPPER
LEVEL LOW WILL ALLOW FOR SOME LIGHT RAIN SHOWERS TONIGHT. POPS
WILL INCREASE AFTER SUNSET, WITH THE HIGHEST PROBABILITY OF
RAINFALL DURING THE MIDDLE OF THE OVERNIGHT. ALL AREAS SHOULD BE
DONE WITH PRECIP TOWARDS SUNRISE ON SATURDAY. OVERALL, RAINFALL
AMOUNTS WILL ON THE LIGHTER SIDE, WITH GENERALLY UNDER A QUARTER
OF AN INCH. ACROSS THE HIGHEST ELEVATIONS OF THE CENTRAL
ADIRONDACKS, THE RAIN MAY MIX WITH OR CHANGE TO WET SNOW, BUT
ANY ACCUMULATION (1" OR LESS) WILL BE LIMITED TO THE MOUNTAIN
PEAK SUMMITS. WITH THE EXPECTED CLOUDS/PRECIP, NO FROST IS
EXPECTED TONIGHT, ALTHOUGH LOWS WILL BE BELOW NORMAL, RANGING
FROM THE LOWER 30S IN THE ADIRONDACKS TO THE LOW TO MID 40S IN
VALLEY AREAS.
AFTER A DRYING DAY ON SATURDAY, THE CORE OF THE UPPER LEVEL
TROUGH WILL BE OVERHEAD FOR SATURDAY NIGHT. THERE SHOULD BE
PLENTY OF CLEARING, ALLOWING FOR A MOSTLY CLEAR SKY ALTHOUGH A
LIGHT WEST TO NORTHWEST BREEZE IS EXPECTED FOR MANY AREAS.
OVERNIGHT LOWS WILL FALL INTO THE 20S AND 30S ACROSS THE
REGION. THE GROWING SEASON BEGAN MAY 1ST (TODAY) FOR THE HUDSON
VALLEY, FAR SOUTHERN TACONICS AND NW CT. SOME FROST ADVISORIES
COULD BE NEEDED ON SATURDAY NIGHT, MAINLY FOR THE UPPER HUDSON
VALLEY. SOME PATCHY FROST WILL ALSO BE POSSIBLE FOR SOME
SHELTERED AND OUTLYING AREAS IN NW CT, THE SOUTHERN TACONICS AND
AROUND THE CAPITAL REGION, ALTHOUGH THE MOST WIDESPREAD
POTENTIAL IS THE GLENS FALLS AND WASHINGTON COUNTY, NY AREA.
SOME PATCHY FROST COULD BE POSSIBLE AGAIN ON SUNDAY NIGHT FOR
NORTHERN VALLEY AREAS, ALTHOUGH THIS LOOKS A LITTLE MORE
UNCERTAIN COMPARED TO SATURDAY NIGHT, AS THERE COULD BE MORE
CLOUDS AND SOME APPROACHING SHOWERS, WHICH MAY KEEP TEMPS A
LITTLE MILDER.
KEY MESSAGE 2...
AS A STRONG STORM SYSTEM PASSES BY TO THE EAST OFF THE
NORTHEAST, THERE WILL BE A STRONG PRESSURE GRADIENT IN PLACE FOR
SUNDAY, BETWEEN THE DEPARTING STORM SYSTEM AND HIGH PRESSURE OFF
TO THE SOUTHWEST. WITH THE UPPER LEVEL TROUGH OVERHEAD, GOOD
MIXING IS EXPECTED THANKS TO THE COOL TEMPS ALOFT. THE
COMBINATION OF THESE FEATURES WILL ALLOW FOR GUSTY WINDS DURING
PEAK HEATING. HAVE LEANED TOWARDS THE NBM 90TH PERCENTILE AND
COLLABORATED AN INCREASE IN WIND GUSTS WITH NEIGHBORING OFFICES.
NORTHWEST WINDS MAY GUST 20-30 MPH FOR THE LATE MORNING THROUGH
THE AFTERNOON HOURS. WITH GOOD MIXING, RH VALUES WILL LOWER
BELOW EXPECTED NBM DEWPOINTS, WITH VALUES AS LOW AS 25-30
PERCENT FOR MANY AREAS.
WE HAVE ALREADY NOTIFIED NYS DEC ABOUT THE POTENTIAL FOR
ELEVATED FIRE WEATHER CONDITIONS ACROSS NEW YORK STATE AND THEY
WILL BE DISCUSSING THE STATE OF THE FUELS FOLLOWING TONIGHT'S
RAINFALL WITH US ON SATURDAY. IF FINE FUELS ARE ABLE TO DRY OUT
(WHICH THEY TYPICALLY DO THIS TIME OF YEAR), THEN RED FLAG
WARNINGS OR SPECIAL WEATHER STATEMENTS WILL BE NEEDED FOR PARTS
OF THE REGION FOR SUNDAY. WITH OUR REGION STILL IN THE PRE-
GREENUP PHASE, IT IS VERY EASY FOR THE COMBINATION OF FUELS, RH
AND WIND GUSTS TO REACH CRITERIA FOR ELEVATED FIRE WEATHER
CONDITIONS. GUSTY WINDS COULD LINGER INTO MONDAY AS WELL. WHILE
SOME ELEVATED RH IS POSSIBLE FOR WESTERN AREAS DUE TO INCREASING
CLOUDS/MOISTURE, LOW RH MAY STILL BE AN ISSUE FOR WESTERN NEW
ENGLAND.
KEY MESSAGE 3...
A RATHER UNSETTLED PATTERN IS EXPECTED NEXT WEEK, SPECIFICALLY
DURING THE MIDDLE OF THE WEEK. A FRONTAL BOUNDARY LOOKS TO
APPROACH ON TUESDAY AND MAY WIND UP STALLING OVER OR NEAR THE
REGION, AS A WAVE OF LOW PRESSURE MOVES ALONG THE FRONTAL ZONE.
THERE REMAINS SOME UNCERTAINTY EXACTLY WHERE THE FRONT MAY
STALL, ALTHOUGH IT DOES APPEAR THAT OUR REGION WILL SEE A WARM
UP AHEAD OF THE FRONT, WITH TEMPERATURES RISING INTO THE 70S ON
TUESDAY. SOME OF THE AI/ML GUIDANCE SUGGESTS THE POTENTIAL FOR
SOME STRONG STORMS AHEAD OF THE FRONT ON TUESDAY, ALTHOUGH THIS
WILL ULTIMATELY DEPEND ON THE EXACT TIMING AND LOCATION OF THE
BOUNDARY, WHICH IS STILL UNKNOWN, AS THE ENSEMBLES ARE STILL
SHOWING PLENTY OF VARIABILITY. WITH REPEATED ROUNDS OF RAINFALL
NEAR THE FRONTAL ZONE, SOME LOCALLY HEAVY DOWNPOURS AND
EXCESSIVE RAINFALL CAN'T BE RULED OUT DURING THE MID-WEKE AS
WELL. THE NBM IS ALREADY SHOWING A 50-80% CHANCE FOR 1" OF
RAINFALL IN TOTAL FOR TUESDAY THROUGH THURSDAY, SO WILL CONTINUE
TO MONITOR MODEL TRENDS.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
THROUGH 18Z SATURDAY... VFR CONDITIONS WILL CONTINUE FOR ALL
TERMINALS UNTIL JUST AFTER SUNSET THIS EVENING. WITH A LOW PRESSURE
MOVING THROUGH TO OUR NORTH, LIGHT TO MODERATE RAIN SHOWERS ARE
EXPECTED MOVING FROM WEST TO EAST ACROSS ALL TERMINALS FROM 02Z-04Z.
MODEL SOUNDINGS HAVE CIGS AND VIS GRADUALLY LOWERING TO MVFR
CONDITIONS BEFORE DETERIORATING TO IFR CIGS FIRST AT KGFL AROUND
02Z, AND FROM 06Z-08Z AT KALB, KPSF, AND KPOU. THICK LOW AND MID
LEVEL CLOUDS WILL PERSIST INTO THE MORNING TOMORROW WITH
IMPROVEMENT TO VFR CONDITIONS RETURNING JUST AROUND OR WITH
DAYBREAK OR JUST BEFORE DAYBREAK FOR KPOU, KPSF, AND KALB. MVFR
CIGS COULD LINGER A LITTLE CLOSER TO NOON AT KGFL BUT SHOULD
RETURN TO VFR AT THE END OF THE TAF PERIOD.
WINDS RANGE FROM WEST TO NORTHWEST WITH SPEEDS 5-10 KT AT KGFL,
KALB, AND KPSF WITH OCCASIONAL GUSTS THROUGH THE EVENING. WINDS
BECOME LIGHT AND VARIABLE ONCE THE RAIN ARRIVES THIS EVENING
AFTER 03Z. KPOU REMAINS LIGHT AND VARIABLE THROUGH MOST OF THE
TAF PERIOD.
