AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
226 PM EDT TUE MAY 19 2026
WHAT HAS CHANGED
CONVECTIVE OUTLOOK HAS BEEN ADJUSTED SLIGHTLY AND THE SLIGHT
RISK REMOVE FROM OUR AREA FOR TODAY, AS THE BEST FORCING AND
ORGANIZED STORMS MAY REMAIN WEST OF THE REGION. STILL, A THREAT
FOR ISOLATED DAMAGING WINDS CONTINUE FOR TODAY FOR NORTHERN
AREAS.
POPS HAVE LOWERED SOMEWHAT FOR TOMORROW ALONG THE FRONT AS
PRECIP SHOULD BE MORE SCATTERED. MANY AREAS MAY STAY DRY AND
THE THREAT FOR JUST ISOLATED STRONG-TO-SEVERE STORMS LOOKS TO BE
FOR FAR SOUTHERN AREAS, AND MAY BE A GREATER THREAT
SOUTH/SOUTHWEST OF THE REGION.
MODELS CONTINUE TO DISAGREE ON THE HANDLING OF PRECIP FOR THIS
WEEKEND, WITH SOME GUIDANCE NOW SUGGESTING
KEY MESSAGES
1) WELL-ABOVE NORMAL TEMPS CONTINUE THIS AFTERNOON. WITH HEAT
RISK VALUES IN THE MODERATE TO LOCALLY MAJOR CATEGORIES, THERE
IS AN INCREASED RISK THIS AFTERNOON FOR HEAT-RELATED ILLNESSES.
2) ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED THIS
AFTERNOON INTO THIS EVENING FOR NORTHERN AREAS AND AGAIN ON
WEDNESDAY FOR SOUTHERN PARTS OF THE REGION. THERE IS A MARGINAL
RISK FOR STORMS TO BE SEVERE, WITH DAMAGING WINDS BEING THE
MAIN THREAT.
3) A RETURN TO MORE SEASONABLE TEMPERATURES IS EXPECTED THURSDAY
INTO FRIDAY WITH THE NEXT CHANCE FOR A WIDESPREAD RAINFALL OVER
THE WEEKEND, ALTHOUGH THE EXACT TIMING, DURATION AND AMOUNT OF
RAINFALL IS STILL UNCERTAIN.
DISCUSSION
KEY MESSAGE 1...
ANOTHER HOT AND HUMID DAY IS ONGOING ACROSS THE REGION. 12Z KALY
SOUNDING SHOWED 850 HPA TEMPS OF AROUND +18 C. VALLEY AREAS HAVE
ALREADY RISEN INTO THE UPPER 80S TO LOW 90S. WITH DEWPOINTS IN
THE 60S, HEAT INDEX VALUES ARE IN THE LOW TO MID 90S IN MANY
VALLEY AREAS, WITH THE HIGHEST VALUES IN THE MID HUDSON VALLEY
WHERE A HEAT ADVISORY IS IN EFFECT. THESE VALUES WILL CONTINUE
THROUGH THE EARLY EVENING HOURS, BUT WILL START TO LOWER FOR
TONIGHT. HEAT RISK VALUES ARE IN THE MODERATE TO MAJOR CATEGORY,
WHICH IS RATHER SIGNIFICANT FOR MID MAY. WITH A LOT OF PEOPLE
STILL NOT USED TO THE HEAT JUST YET, THERE WILL BE AN INCREASED
RISK FOR HEAT RELATED ILLNESSES THROUGH THE REST OF THE DAY.
COOLER AND DRIER AIR WILL BE ARRIVING WITH A COLD FRONT FOR
WEDNESDAY. WHILE NORTHERN AREAS WILL SEE RELIEF EARLY IN THE DAY
WITH STEADY/FALLING TEMPS FOR THE DAY, FAR SOUTHERN AREAS WILL
BE AHEAD OF THE FRONT FOR MUCH OF THE DAY. HIGHS WILL BE CLOSE
90 IN THE MID HUDSON VALLEY ONCE AGAIN WITH MODERATE HEAT RISK.
COOLER AND DRIER WILL ARRIVE FOR THE ENTIRE AREA FOR WEDNESDAY
NIGHT.
KEY MESSAGE 2...
OUR REGION IS ON THE NORTHERN FRINGE OF A LARGE UPPER LEVEL
RIDGE CENTERED OVER THE EASTERN SEABOARD. UPPER LEVEL SHORTWAVE
IS WELL WEST OF THE AREA OVER THE UPPER MIDWEST. AT THE SURFACE,
A COLD FRONT REMAINS WELL UPSTREAM OF THE REGION OVER THE GREAT
LAKES, ALTHOUGH A PRE-FRONTAL SURFACE TROUGH IS LOCATED OVER
THE AREA.
SPC MESOANALYSIS SHOWS 0-6 KM BULK SHEAR IS AROUND 30 KTS, WITH
THE HIGHEST VALUES ACROSS NORTHERN PARTS OF THE AREA. MEANWHILE,
A WARM AND HUMID AIRMASS (SURFACE TEMPS APPROACHING 90 IN MANY
AREAS) IS ALLOWING FOR INSTABILITY, WITH MLCAPE MAINLY IN THE
500-1000 J/KG RANGE, WITH THE BEST VALUES TO THE SOUTH. WITH THE
WARM TEMPS ALOFT, MID LEVEL LAPSE RATES ARE RATHER POOR,
GENERALLY UNDER 6 DEG C/KM. LOW LEVEL LAPSE RATES ARE STRONG,
HOWEVER, DUE TO THE STRONG SOLAR HEATING TODAY.
OVERALL, COVERAGE OF STORMS THIS AFTERNOON INTO THIS EVENING
LOOKS ISOLATED TO SCATTERED. BASED OFF THE LATEST CAMS, ACTIVITY
MAY DEVELOP OVER THE NEXT FEW HOURS ACROSS NORTHERN AREAS AND
SLIDE EASTWARD, ALTHOUGH IT MAY NOT GET TOO ORGANIZED ACROSS OUR
AREA WITH THE BETTER FORCING STILL WELL OFF TO THE WEST. THERE
IS ENOUGH OVERLAP OF SHEAR/INSTABILITY FOR A FEW STORMS TO BE
SEVERE AND DAMAGING WINDS WOULD BE THE MAIN THREATS DUE TO THE
DECENT SHEAR AND STRONG LOW LEVEL LAPSE RATES. WHILE A FEW
REPORTS OF DAMAGING WINDS CAN'T BE RULED OUT, THE LIMITED
FORCING AND POOR MID LEVEL LAPSE RATES WILL LIKELY KEEP A LARGE
SEVERE OUTBREAK FROM OCCURRING.
ON WEDNESDAY, SOME ADDITIONAL STORMS WILL BE POSSIBLE ACROSS FAR
SOUTHERN AREAS IN THE AFTERNOON HOURS, AS THE MAIN COLD FRONT
SETTLES SOUTHWARD. THE REST OF THE AREA WILL BE BEHIND THE
BOUNDARY, BUT DUTCHESS AND LITCHFIELD COUNTIES COULD SEE A FEW
STRONG STORMS WITH ANOTHER DAY OF WARM AND HUMID WEATHER
EXPECTED AHEAD OF THE FRONT. SPC MAINTAINS A MARGINAL RISK FOR
FAR SOUTHERN PARTS OF OUR AREA, ALTHOUGH AI/ML GUIDANCE
SUGGESTS THAT THERE MAY BE A SLIGHTLY HIGHER THREAT FURTHER
SOUTH ACROSS PA/NJ OR COASTAL NEW ENGLAND.
KEY MESSAGE 3...
WEST TO NORTHWEST FLOW WILL TAKE OVER FOR THE LATE WEEK. MORE
SEASONABLE TEMPS ARE EXPECTED FOR THURSDAY AND FRIDAY WITH
VALLEY HIGHS MAINLY IN THE 60S. OVERNIGHT TEMPS WILL BE IN THE
40S, WITH SOME MID TO UPPER 30S OVER THE HIGHEST TERRAIN. DRY
AND COMFORTABLE WEATHER WILL BE IN PLACE FOR ALL OF THURSDAY AND
FRIDAY WITH A PARTLY TO MOSTLY CLEAR SKY.
UNSETTLED WEATHER IS EXPECTED FOR THE WEEKEND, ALTHOUGH MODEL
GUIDANCE HAS BEEN VARYING REGARDING THE EXACT TIMING OF PRECIP.
A PERIOD OF STEADY RAINFALL IS POSSIBLE THANKS TO SURFACE LOW
PRESSURE HEADING TOWARDS THE GREAT LAKES AND WARM ADVECTION/
ISENTROPIC LIFT AHEAD OF THE WARM FRONT. THIS COULD OCCUR AS
EARLY AS SATURDAY, ALTHOUGH LATEST MODEL GUIDANCE HAS BEEN
SLOWING DOWN THE TIMING OF THIS AND/OR KEEPING THE BULK OF IT TO
THE SOUTH AND WEST. FOR NOW, HAVE GONE CLOSE TO THE NBM WITH
LIKELY POPS FOR SATURDAY, BUT THERE IS POTENTIAL FOR DRIER
WEATHER. WHILE THERE SHOULD BE A BREAK AT SOME POINT (PERHAPS
FOR SUNDAY), ANOTHER ROUND OF SHOWERS IS EXPECTED (SUNDAY NIGHT
AND/OR MONDAY) AS THE MAIN UPPER LEVEL DISTURBANCES TRACKS
ACROSS THE REGION. FOR NOW, WILL KEEP POPS CLOSE TO CHANCE FOR
SUN/MON. WHILE SOME RAIN IS POSSIBLE, IT MAY NOT BE TOTALLY
RAINING ENTIRELY THESE TWO DAYS, SO SOME DRY WEATHER IS POSSIBLE
FOR A PORTION OF THE HOLIDAY WEEKEND.
WITH THE CLOUDS AND POSSIBLE PRECIP, TEMPS MAY BE HELD DOWN
SOMEWHAT THIS WEEKEND, WITH MID TO UPPER 60S, ALTHOUGH IF SOME
SUN DOES OCCUR, THEN HIGHS IN THE 70S ARE CERTAINLY POSSIBLE.
ULTIMATELY, IT WILL DEPEND ON THE EXACT TIMING/TRACK OF THE
PRECIP, WHICH SHOULD COME INTO BETTER FOCUS OVER THE NEXT FEW
DAYS.
AVIATION /18Z TUESDAY THROUGH SUNDAY/
THROUGH 18Z WEDNESDAY... VFR CONDITIONS ARE EXPECTED ACROSS ALL
TERMINALS FOR MOST OF THE TAF PERIOD. THERE IS A CHANCE FOR
ISOLATED THUNDERSTORMS THIS AFTERNOON INTO THIS EVENING, PRIMARILY
AT KGFL AND KPSF. WHILE WE HAVE PLENTY OF INSTABILITY FOR STORMS
TO DEVELOP, THE OVERALL LACK OF FORCING IS KEEPING CONFIDENCE
LOW AT THIS TIME, SO REFLECTED THIS BY USING PROB30 GROUPS AT
KGFL AND KPSF. BRIEF PERIODS OF MVFR VIS ARE POSSIBLE WITH HEAVY
DOWNPOURS ASSOCIATED WITH THESE STORMS, BUT CIGS SHOULD REMAIN
VFR.
SOUTHWESTERLY GUSTY WINDS START OFF THE TAF PERIOD ACROSS ALL
TERMINALS, WHICH WILL BEGIN TO SUBSIDE AROUND 22Z-00Z TONIGHT
AHEAD OF AN APPROACHING COLD FRONT. THE FRONT WILL BEGIN TO PASS
THROUGH THE REGION AROUND 12Z WEDNESDAY, WITH WINDS SHIFTING
OUT OF THE WEST TO WEST-NORTHWEST AND A RETURN OF GUSTS UP TO
20-30 KTS. BRIEF PERIODS OF MVFR CIGS ARE POSSIBLE TOMORROW
MORNING AT KGFL, KALB, AND KPSF BEFORE SCATTERING BACK UP TO VFR
BY THE END OF THE PERIOD AT ALL TERMINALS EXCEPT FOR KPSF.
