KEY MESSAGES
* COOLER AND MUCH DRIER AIR MOVES IN TODAY WITH ANOTHER QUICK
HEATWAVE MOVING IN TUESDAY-WEDNESDAY
* NEXT SOLID RAIN CHANCE COMES WEDNESDAY NIGHT-THURSDAY AS ANOTHER
COOL FRONT SWINGS THROUGH THE REGION
SHORT TERM /THROUGH TONIGHT/
ISSUED AT 222 AM EDT SUN SEP 6 2026
WAITING PATIENTLY FOR THE DRY AIR TO GET INTO OUR AREA EARLY THIS
MORNING. GOES SOUNDER DATA STILL HAS A GENERAL 1.4-1.6" PRECIPITABLE
WATER OVER ALL OF THE AREA, BUT A SHARP GRADIENT IS INCHING CLOSER
TO SOUTHERN IN/OH THIS HOUR, WITH READINGS OF 1.1-1.2" NORTH OF THAT
GRADIENT. INCREASING NORTH TO NORTHEAST WINDS THIS MORNING AND THE
REST OF THE DAY WILL, ALONG WITH A DEEP NORTHERLY FLOW ALOFT, PULL
THAT DRIER AIR DOWN AND BRING AN END TO MEASURABLE RAIN CHANCES BY
THIS AFTERNOON.
TEMPERATURES WILL RUN MUCH COOLER, BREAKING OUR STREAK OF HOT DAYS.
LOOKING AT READINGS IN THE MID 80S FOR THE I-64 CORRIDOR AND UPPER
90S AS YOU GET CLOSER TO BWG. THE LOWER DEWPOINT AIR WILL ALLOW FOR
OVERNIGHT LOWS TO FALL OFF QUICKLY TOO, BOTTOMING OUT IN THE LOWER
60S FOR MOST, SAVE FOR SDF AND BWG AREA.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 222 AM EDT SUN SEP 6 2026
HIGH PRESSURE MOVING ACROSS THE GREAT LAKES REGION WILL KEEP US DRY
AND COOLER MONDAY, BUT THEN IT WILL SHIFT EASTWARD AS WE GO TO
MIDWEEK. AN UPPER RIDGE OVER THE CENTRAL U.S. ALSO WILL SHIFT
EASTWARD. THE COMBINATION OF HIGHER THICKNESSES AND SOUTHERLY WINDS
WILL BRING A RETURN TO ABOVE NORMAL TEMPERATURES FOR TUE/WED.
THE UPPER RIDGE DOES LOOK TO FLATTEN OUT WED/THU, AS ANOTHER COOL
FRONT DROPS INTO THE MIDWEST. PASSAGE LOOKS TO BE IN THE WED.
NIGHT/THURSDAY TIME FRAME. TROUGHING ALOFT MAY BRING YET ANOTHER
COOL FRONT FRIDAY NIGHT/SATURDAY.
AVIATION /12Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 641 AM EDT SUN SEP 6 2026
STARTING TO SEE MORE NORTH AND NORTHEASTERLY WINDS AT THE VARIOUS
TERMINALS EARLY THIS MORNING. EXPECT A LITTLE STRONGER WINDS BY LATE
MORNING AS HIGH PRESSURE BUILDS IN TO THE REGION. SEEING THAT
STRATUS DECK DEVELOPING QUICKLY ACROSS THE NORTHERN TERMINALS, AND
IT SHOULD LINGER SEVERAL HOURS THIS MORNING. KBWG, WITH THE SATURDAY
EVENING RAINS AND A BRIEF CLEAR OUT HAD SOME LIGHT FOG DEVELOP
EARLIER. IT HASN'T BEEN TOO BAD THOUGH. STILL COULD TRANSITION TO A
STRATUS DECK, BUT IN GENERAL IMPROVED THE TAF'S THERE WITH THIS SET.
DRIER AIR FILTERING IN WITH THOSE WINDS EVENTUALLY SHOULD THINK OUT
ANY CLOUD DECKS BY EARLY TO MID AFTERNOON.
