DISCUSSION
ISSUED AT 227 PM EDT SUN AUG 23 2026
PATTERN SYNOPSIS:
IMPRESSIVE LATE-SUMMER TROUGHING WILL CONTINUE TO CHURN OVER THE
GREAT LAKES TONIGHT AS IT EVENTUALLY LIFTS NORTHEAST EARLY THIS
WEEK. THE ASSOCIATED SURFACE CYCLONE CENTERED ALONG THE
ONTARIO/QUEBEC BORDER WILL WEAKEN WITH TIME AS THE SYSTEM BECOMES
INCREASINGLY VERTICALLY STACKED, CUTTING OFF FAVORABLE ADVECTIONS
FOR SUPPORT. MEANWHILE, RIDGING SLIDING OVER THE NORTHERN GREAT
PLAINS WILL HELP BUILD SURFACE HIGH PRESSURE ACROSS THE REGION
THROUGH THE FIRST HALF OF THE WEEK. TROUGHING EVENTUALLY WORKS BACK
OVERHEAD DURING THE SECOND HALF OF THE WEEK, LIKELY BRINGING ANOTHER
SYSTEM ACROSS THE GREAT LAKES IN THE LATE WEDNESDAY/THURSDAY
TIMEFRAME.
FORECAST DETAILS:
FALL-FEELING WEATHER ACROSS THE AREA TODAY WITH BREEZY WINDS AND
COOL TEMPERATURES WILL CONTINUE INTO MONDAY. WHILE AFTERNOON HIGHS
WILL BE A FEW DEGREES WARMER ON MONDAY, READINGS ARE STILL EXPECTED
TO STAY IN THE UPPER 60S TO LOW 70S FOR MOST OF THE AREA -- AROUND 5
DEGREES COOLER THAN LATE-AUGUST AVERAGES. NORTHWEST WINDS BETWEEN 10-
20 MPH WITH GUSTS TO 25-35 MPH WILL PERSIST THIS AFTERNOON AND
CONTINUE MONDAY AS WELL, ALTHOUGH SLIGHTLY LESS WINDY CONDITIONS ARE
ANTICIPATED TOMORROW. ISOLATED TO SCATTERED LIGHT LAKE ENHANCED RAIN
SHOWERS TODAY ARE ALSO EXPECTED TO DRAW TO A CLOSE FOR MOST AREAS
LATER THIS EVENING AND TONIGHT AS AN INCREASINGLY HOSTILE
ENVIRONMENT MOVES IN AS AFOREMENTIONED HIGH PRESSURE BUILDS. THE
EXCEPTION WILL BE ACROSS THE FAR EASTERN U.P./LAKE HURON SHORELINE
TONIGHT INTO EARLY MONDAY MORNING AS RAIN LOOKS TO LINGER ON THE
BACKSIDE OF THE SYSTEM AS IT EXITS. CANNOT COMPLETELY RULE OUT A FEW
SHOWERS MONDAY, BUT THE FIRST HALF OF THE WEEK IS EXPECTED TO BE DRY
ACROSS NORTHERN MICHIGAN.
OUR NEXT CHANCES FOR RAIN WILL RETURN LATE WEDNESDAY AND THURSDAY AS
TROUGHING DIGS BACK INTO THE GREAT LAKES. TIMING APPEARS TO BE
DELAYED SOME FROM PREVIOUS FORECAST CYCLES, POTENTIALLY KEEPING MOST
OF WEDNESDAY DRY. THAT SAID, STEADIER RAIN CHANCES APPEAR
INCREASINGLY LIKELY IN THE FRONT END OF THIS SYSTEM LATE
WEDNESDAY/EARLY THURSDAY WITH ADDITIONAL RAIN SHOWERS POSSIBLE
THROUGH LATE THURSDAY ON THE BACKSIDE OF THE DEPARTING SYSTEM.
OTHERWISE, HIGHS WILL WARM BACK INTO THE UPPER 70S AND LOW 80S BY
TUESDAY WITH TEMPERATURES SET TO COOL BACK INTO THE UPPER 60S AND
70S DURING THE SECOND HALF OF THE WEEK.
