AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
151 PM EDT THU MAY 7 2026
WHAT HAS CHANGED
CONTINUE TO INCLUDE FROST FOR THE UPPER HUDSON VALLEY FOR
TONIGHT, BUT CLOUDS MAY INCREASE LATE DUE TO AN APPROACHING
UPPER LEVEL DISTURBANCE. BEHIND THIS FEATURE, HAVE LOWERED
DEWPOINTS FROM NBM VALUES FOR TOMORROW AFTERNOON WITHIN DAYTIME
MIXING.
KEY MESSAGES
1) LOCALIZED AREAS OF FROST EXPECTED ACROSS THE UPPER HUDSON
VALLEY TONIGHT DUE TO TEMPERATURES IN THE MID 30S, WHICH MAY
IMPACT SENSITIVE OUTDOOR VEGETATION.
2) UNSETTLED PATTERN THIS WEEKEND INTO EARLY NEXT WEEK, ALONG
WITH BELOW NORMAL TEMPERATURES. WHILE SOME PERIODS OF RAIN
SHOWERS ARE EXPECTED, NO HYDROLOGIC IMPACTS OR THUNDERSTORMS ARE
ANTICIPATED AT THIS TIME.
DISCUSSION
KEY MESSAGE 1...
VISIBLE SATELLITE IMAGERY SHOWS DIURNAL CU/STRATOCU OVER THE
REGION. DESPITE GOOD MIXING, TEMPERATURES HAVE BEEN BELOW NORMAL
TODAY WITH VALUES ONLY IN THE 50S FOR MOST AREAS. WITH THE LOSS
OF DAYTIME HEATING, CLOUDS WILL QUICKLY DIMINISH THIS EVENING
AND WINDS WILL BE DECREASING AS WELL. THIS SHOULD ALLOW FOR
TEMPERATURES TO QUICKLY COOL OFF, ESPECIALLY FOR SHELTERED AREAS
OF THE UPPER HUDSON VALLEY, SUCH AS IN THE GLENS FALLS AREA.
AN UPPER LEVEL TROUGH WILL BE MOVING OVERHEAD OVERNIGHT AND A
FAST MOVING DISTURBANCE ROTATING AROUND THE BASE OF THE TROUGH
WILL APPROACH FOR THE LATE NIGHT HOURS. THERE COULD BE A FEW
LIGHT RAIN SHOWERS ACROSS FAR SOUTHERN AREAS LATE TONIGHT, BUT
ALL AREAS MAY SEE CLOUD COVER INCREASING. CLOUDS MAY STILL BE
THIN ENOUGH FOR TEMPS TO CONTINUE TO FALL DURING THE LATE
OVERNIGHT HOURS AND LOWS IN THE GLENS FALLS AREA WILL BE IN THE
MIDDLE 30S. THIS MAY RESULT IN SOME AREAS OF FROST, WHICH COULD
IMPACT ANY SENSITIVE, TENDER AND/OR YOUNG VEGETATION THAT HAS
BEEN PUT OUTDOORS EARLY THIS SEASON. A FROST ADVISORY IS IN
EFFECT FOR WASHINGTON, SE WARREN AND NORTHERN SARATOGA COUNTIES,
AND GARDENERS AND GROWERS ARE ENCOURAGED TO PROTECT ANY
SENSITIVE PLANTS IN THIS AREA FOR TONIGHT. LUCKILY, TEMPERATURES
AREN'T EXPECTED TO DROP BELOW FREEZING FOR ANY AREAS WHERE THE
GROWING SEASON HAS ALREADY BEGUN. TEMPERATURES SHOULD QUICKLY
RISE AFTER SUNRISE, ENDING THE THREAT FOR FROST.
KEY MESSAGE 2...
UNSETTLED WEATHER IS EXPECTED FOR MUCH OF THIS WEEKEND AND INTO
EARLY NEXT WEEK. AN UPPER LEVEL TROUGH WILL BE MOVING OVER THE
REGION FOR FRIDAY INTO SATURDAY. BEHIND THIS FEATURE, THERE WILL
BE A BRIEF BREAK BEFORE ANOTHER UPPER LEVEL TROUGH MOVES ACROSS
THE REGION FOR SUNDAY NIGHT INTO EARLY NEXT WEEK.
A FEW PASSING SHOWERS CAN'T BE RULED OUT ON FRIDAY, BUT THE
BETTER CHANCE FOR A STEADY LIGHT RAIN LOOKS TO BE LATE FRIDAY
NIGHT INTO SATURDAY, ESPECIALLY FOR SOUTHERN AREAS, AS WARM
ADVECTION AND AN AREA OF LOW PRESSURE ALLOW FOR A MORE ORGANIZED
AREA OF RAINFALL. STILL, RAINFALL RATES AND TOTAL AMOUNTS DON'T
LOOK EXCESSIVE, WITH MAINLY A TENTH TO A QUARTER OF AN INCH FOR
MOST AREAS. TEMPERATURES WILL BE HELD DOWN DUE TO THE COOLER
TEMPS, CLOUDS AND POSSIBLE RAINFALL FOR BOTH FRIDAY AND
SATURDAY, WITH 50S FOR MOST OF THE AREA.
THERE MAY BE A SLIGHT IMPROVEMENT IN THE TEMPS FOR SUNDAY WITH
SOME WARMER TEMPS ALOFT AND BRIEFLY RISING HEIGHTS, WITH 60S FOR
HIGHS IN VALLEY AREAS. HOWEVER, ANOTHER CHANCE FOR RAINFALL WILL
ARRIVE FOR LATE IN THE DAY INTO SUNDAY NIGHT AS ANOTHER COLD
FRONT ON THE LEADING EDGE OF THE NEXT TROUGH ARRIVES AND BRINGS
SOME MORE SHOWERS, ESPECIALLY FOR SOUTHERN AND EASTERN PARTS OF
THE REGION. TEMPERATURES WILL BE BELOW NORMAL AGAIN FOR EARLY
NEXT WEEK, WITH PLENTY OF CLOUDS AND SOME ADDITIONAL SPOTTY
SHOWERS WITHIN THE CYCLONIC FLOW OF THE UPPER LEVEL TROUGH.
AT THIS TIME, RAINFALL DOESN'T APPEAR TO BE EXCESSIVE THROUGH
EARLY NEXT WEEK AND NO THUNDER IS EXPECTED DUE TO LIMITED
INSTABILITY. WHILE THE WEATHER PATTERN ISN'T IDEAL FOR OUTDOOR
PLANS EACH DAY, THERE WON'T BE ANY THREATS FOR HAZARDOUS WEATHER
THROUGH AT LEAST EARLY NEXT WEEK.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
THROUGH 18Z FRIDAY... VFR CONDITIONS WILL PREVAIL ACROSS ALL
TERMINALS THROUGHOUT MUCH OF THE TAF PERIOD. WINDS WILL INITIALLY
REMAIN MODERATE AND GUSTY AT KGFL, KALB, AND KPSF WITH GUSTS
REACHING UP TO 20-25 KTS THROUGH THIS EVENING. THESE WINDS WILL
BEGIN TO SUBSIDE AROUND SUNSET AS HIGH PRESSURE MOVES IN ACROSS
THE REGION, LEADING TO LIGHT AND VARIABLE WINDS AT KGFL, KPOU,
AND KPSF WITH SKIES LIKELY CLEARING. THE ONLY EXCEPTION IS KPOU
WHICH WILL LIKELY HAVE SOME LINGER MID-LEVEL CLOUDS.
MORE MID-TO-HIGH LEVEL CLOUDS WILL BEGIN TO BUILD IN ACROSS THE
REGION AROUND 04Z-05Z, WITH THE POTENTIAL FOR SOME SCATTERED
RAIN SHOWERS AT KPOU. THESE SHOWERS SHOULD NOT IMPACT VISIBILITY,
BUT THERE IS A CHANCE FOR CIGS TO TEMPORARILY LOWER TO MVFR SO
WENT WITH A PROB30 FOR NOW. SOUTHWESTERLY WINDS WILL BEGIN TO
PICK UP AGAIN BY FRIDAY MORNING, WITH KPOU AND KPSF SEEING A
RETURN OF MODERATE GUSTS UP TO 15 KTS. CIGS WILL BEGIN TO BECOME
MORE BKN BY THE LAST SEVERAL HOURS OF THE TAF PERIOD, BUT WILL
REMAIN VFR THROUGH THE END OF THE PERIOD.
