AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
225 AM EDT THU JUL 16 2026
WHAT HAS CHANGED
SMOKE LOOKS TO BE QUITE WIDESPREAD AND THICK TODAY, SO WILL
CONTINUE MENTION ACROSS THE ENTIRE AREA. THIS WILL RESULT IN
COOLER TEMPERATURES, SO NBM VALUES WERE REDUCED BY SEVERAL
DEGREES.
KEY MESSAGES
1) WIDESPREAD SMOKE AND HAZE FROM WILDFIRES IN CANADA WILL
CONTINUE TO MOVE ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND
THROUGH TODAY.
2) UNSETTLED WEATHER RETURNS FOR THE WEEKEND, WITH SHOWERS AND
THUNDERSTORMS BECOMING LIKELY BY SATURDAY.
DISCUSSION
KEY MESSAGE 1...
SMOKE AND THICK, HAZY SKIES WILL BE PREVALENT ACROSS THE REGION
TODAY. BOTH THE VERTICALLY-INTEGRATED AND NEAR-SURFACE SMOKE
FORECASTS FROM THE HRRR SHOW HIGH CONCENTRATIONS THROUGH TODAY.
MAINLY EFFECTS FROM THE SMOKE WILL BE BOTH POOR AIR QUALITY AND
REDUCED VISIBILITY. ALSO TEMPERATURES WILL BE MUCH COOLER THAN
THEY OTHERWISE WOULD BE TODAY. HIGHS EXPECTED TO ONLY REACH THE
MID 70S TO LOWER 80S ACROSS MOST OF THE AREA TODAY AS A RESULT
OF THE SMOKE/HAZE. AS WINDS TURN MORE NORTHWEST THIS EVENING,
SMOKE WILL SHIFT SOUTH AND BECOME SUPPRESSED TO OUR SOUTH
TONIGHT.
KEY MESSAGE 2...
AS ANOTHER COLD FRONT PUSHES SOUTH ACROSS THE AREA TODAY,
WIDELY SCATTERED SHOWERS OR AN ISOLATED T-STORM IS POSSIBLE FOR
AREAS NORTH OF ALBANY. OTHERWISE, MAINLY DRY CONDITIONS WILL
PERSIST THROUGH FRI. ANY STORMS TODAY SHOULD BE NON-SEVERE AS
INSTABILITY WILL BE LIMITED, ESPECIALLY WITH THE WIDESPREAD
SMOKE/HAZE AROUND.
THE NEXT LIKELIHOOD OF MORE WIDESPREAD SHOWERS WITH SOME
T-STORMS ALSO POSSIBLE, WILL BE SAT INTO EARLY SUN AS AN
ANOMALOUSLY STRONG CYCLONE (MSLP ANOMALIES OF -2 TO -3 STDEV)
AND A POTENT SHORT WAVE TROUGH ALOFT WILL BE APPROACHING FROM
THE GREAT LAKES/SE CANADA. TIMING LOOKS TO BE MAINLY ARRIVING
DURING THE AFTERNOON/EVENING HOURS. PWAT ANOMALIES FORECAST TO
RISE TO +1 TO +2 STDEV, SO SOME LOCAL DOWNPOURS MAY OCCUR,
ESPECIALLY WITHIN ANY EMBEDDED CONVECTION. OVERALL THE SHOWERS
WILL BE BENEFICIAL AS THERE HASN'T BEEN ANY WIDESPREAD RAINFALL
FOR OVER A WEEK. THE SEVERE THREAT LOOKS MUDDLED, AS THE
MAGNITUDE OF INSTABILITY WILL BE THE MAIN QUESTION. CLOUDS
AND/OR SMOKE/HAZY COULD LIMIT INSTABILITY DEPENDING
COVERAGE/THICKNESS. WILL CONTINUE TO MONITOR TRENDS. CONDITIONS
WILL GRADUALLY IMPROVE ON SUN, AS THE SYSTEM SHIFTS EAST OF THE
AREA.
WITH A BROAD UPPER LEVEL TROUGH EXPECTED TO REMAIN IN PLACE
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK, A SHORT WAVE MOVING
THROUGH THE MEAN TROUGH LOOKS TO MOVE THROUGH IN THE TUE-WED
TIME FRAME. THIS SYSTEM BRING THE NEXT CHANCE OF
SHOWERS/T-STORMS. SHOULD SUFFICIENT INSTABILITY DEVELOP, SOME
STRONGER STORMS MAY OCCUR, WITH FAIRLY STRONG KINEMATICS IN
PLACE FOR MID-LATE JULY.
AVIATION /06Z THURSDAY THROUGH MONDAY/
THROUGH 06Z FRIDAY...MAINLY VFR CONDITIONS ARE EXPECTED THROUGH
THE REST OF TONIGHT, ALTHOUGH SMOKE/HAZE LAYER COULD PRODUCE
MVFR VSBY AT TIMES, ESPECIALLY NEAR KPOU JUST PRIOR TO 12Z.
AFTER 12Z, SURFACE-BASED SMOKE FROM UPSTREAM CANADIAN WILDFIRES
WILL REDUCE VSBY TO MVFR OR EVEN OCCASIONAL IFR LEVELS, WITH
LOWEST VSBY EXPECTED THIS AFTERNOON AT KALB, KPOU AND KPSF.
WIDELY SCATTERED SHOWERS WILL ALSO BE POSSIBLE LATER IN THE
AFTERNOON AT KGFL, KALB AND KPSF AHEAD OF AN APPROACHING
SECONDARY COLD FRONT, WHICH COULD ALSO REDUCE VSBY TO LOW MVFR
OR IFR WHEN COMBINED WITH THE EXISTING SMOKE/HAZE. WINDS WILL
INITIALLY BE LIGHT AND VARIABLE, BECOMING WEST-NORTHWEST AROUND
10-15 KT WITH GUSTS OF 20-25 KT DEVELOPING.
