PATTERN SYNOPSIS/FORECAST: MID-UPPER LEVEL RIDGING ENCOMPASSES MUCH
OF THE CONUS EARLY THIS MORNING, SANDWICHED BETWEEN CLOSED UPPER LOW
PRESSURE OVER THE PAC NW AND OVER QUEBEC/NEWFOUNDLAND, WITH BROAD
TROUGHING FROM THE LATTER EXTENDING ACROSS THE EASTERN GREAT LAKES
AND NEW ENGLAND. BROAD SURFACE HIGH PRESSURE EXTENDS FROM NORTHEAST
MANITOBA SOUTHWARD THROUGH MUCH OF THE MISSISSIPPI VALLEY INTO THE
WESTERN GREAT LAKES. NEAR-TERM CONCERNS CONTINUE TO REVOLVE AROUND
ONGOING WILDFIRE SMOKE, BUT EVENTUALLY TURN TO INCOMING SHOWER/STORM
CHANCES FRIDAY - SATURDAY, AND AGAIN EARLY NEXT WEEK, AS A SERIES OF
MORE POTENT MID-LEVEL WAVES TREK ACROSS THE NORTHERN GREAT LAKES.
FORECAST DETAILS: NEAR-SURFACE SMOKE LIKELY TO PERSIST TODAY AND
LIKELY THROUGH MUCH OF FRIDAY. AIR QUALITY CONCERNS LIKELY TO
CONTINUE THROUGH THE DURATION AS NEARLY ALL SMOKE-ALLOWING GUIDANCE
CONTINUED TO DEPICT SUB 3 MILE VISIBILITIES BEING COMMON FOR AT
LEAST THE NEXT 36 HOURS. THIS LIKELY TO CONTINUE TO PREVENT MAX
DAYTIME HEATING WITH DAYTIME HIGHS RANGING FROM THE MID-UPPER 70S TO
MID-80S AREA-WIDE...SEVERAL DEGREES COOLER THAN WHAT HIGH TEMPS
WOULD BE PROGGED AT WITHOUT THE SMOKE.
WITH RESPECT TO PRECIP CHANCES MOVING FORWARD, A MORE PROMINENT
SHORTWAVE TROUGH IS EXPECTED TO CROSS THE AREA ON SATURDAY, WITH
INCREASING FORCING/MOISTURE OUT AHEAD. INITIAL CHANCES FOR A FEW
SHOWERS FRIDAY, PERHAPS AN ISOLATED THUNDERSTORM, MORE NUMEROUS
SHOWERS AND STORMS BECOME LIKELY FRIDAY NIGHT INTO SATURDAY. CAN'T
ENTIRELY RULE OUT STRONGER STORMS FRIDAY NIGHT, ESPECIALLY IF ANY
UPSTREAM CONVECTIVE DEVELOPMENT DURING THE DAY FRIDAY IS ABLE TO
MAINTAIN ITSELF THIS FAR EAST. GUSTY WINDS WOULD BE THE PRIMARY
THREAT, ALONG WITH LOCALLY HEAVY RAINFALL.
LATEST TRENDS FAVOR DRIER CONDITIONS TO WRAP UP THE WEEKEND BY LATER
SATURDAY THROUGH SUNDAY. ADDITIONAL SHOWER/STORM CHANCES RETURN
MONDAY, PERHAPS INTO TUESDAY, WITH COOLER/BELOW NORMAL TEMPERATURES
FAVORED TUESDAY THROUGH THE END OF THE FORECAST PERIOD.
AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
ISSUED AT 1131 PM EDT WED JUL 15 2026
SMOKE CONTINUES TO BE THE PRIMARY CONCERN THROUGH THE ENTIRETY OF THIS
TAF PERIOD. SEE LITTLE EVIDENCE FOR MUCH IMPROVEMENT, WITH BOTH
MVFR TO IFR CONDITIONS EXPECTED FROM DEEP LAYER SMOKE, WITH
WIDESPREAD VIS RESTRICTIONS EXPECTED TO CONTINUE. DO EXPECT AT
LEAST SOME FLUCTUATIONS AS POCKETS OF MORE DENSE SMOKE PASS
OVERHEAD, ALTHOUGH TIMING OF SUCH REMAINS VERY UNCERTAIN. FUTURE
AMENDMENTS TO TAFS MORE THAN ANTICIPATED. LIGHT WINDS WILL
CONTINUE.
