SHORT TERM
ISSUED 149 PM CST SAT NOV 22 2025
TONIGHT THROUGH SUNDAY NIGHT:
MID LEVEL CLOUDS ARE MOVING ACROSS THE REGION THIS AFTERNOON,
AHEAD OF A COLD FRONT. THESE CLOUDS HAVE PRODUCED A FEW SPITS OF
RAIN AND SNOW, AND WHILE ANOTHER BRIEF PERIOD OF SPRINKLES OR
DRIZZLE WILL BE POSSIBLE WITH THE ACTUAL FRONT LATER THIS
AFTERNOON, NO MEANINGFUL PRECIPITATION IS EXPECTED. SKIES WILL
CLEAR THIS EVENING AS DRIER AIR BUILDS INTO THE REGION.
SUNDAY LOOKS TO BE A FAIRLY PLEASANT DAY. TEMPERATURES WILL
START THE DAY IN THE LOW 30S, BEFORE WARMING INTO THE UPPER 40S
TO NEAR 50. LIGHT NORTHWEST WINDS ARE EXPECTED EARLY, EVENTUALLY
TURNING SOUTHWESTERLY BY LATE AFTERNOON AND EVENING.

LONG TERM
ISSUED 149 PM CST SAT NOV 22 2025
MONDAY THROUGH SATURDAY:
AN UPPER LEVEL DISTURBANCE WILL MOVE OUT OF THE CENTRAL PLAINS
SUNDAY NIGHT AND MONDAY, LIFTING INTO THE GREAT LAKES BY
TUESDAY. WARM ADVECTION AHEAD OF THIS FEATURE WILL BRING
LIGHT RAIN SHOWERS TO THE REGION MONDAY AFTERNOON THROUGH MONDAY
NIGHT. THERE'S A GOOD CHANCE (>75%) FOR RAIN DURING THIS
TIMEFRAME, THOUGH OVERALL AMOUNTS WILL REMAIN QUITE LIGHT.
BEHIND THIS INITIAL WAVE, ANOTHER, STRONGER SHORTWAVE WILL PUSH
EASTWARD OVER THE NORTHERN PLAINS ON TUESDAY, WITH CYCLOGENESIS
TAKING PLACE OVER NORTHERN WISCONSIN TUESDAY AND TUESDAY NIGHT.
THE SURFACE LOW IS EXPECTED TO DEEPEN OVER LAKE SUPERIOR TUESDAY
NIGHT AND WEDNESDAY, WITH AN ASSOCIATED COLD FRONT SURGING
ACROSS THE REGION EARLY WEDNESDAY. AFTER REACHING THE 50S ON
MONDAY AND TUESDAY, TEMPERATURES WILL REMAIN IN THE 30S
WEDNESDAY. DAYTIME HIGHS ON WEDNESDAY LOOK TO BE MET IN THE
MORNING HOURS, WITH FALLING TEMPERATURES PROBABLE DURING THE
AFTERNOON.
DESPITE ITS STRENGTH, NOT A LOT OF PRECIPITATION IS EXPECTED
WITH THIS FRONT. SOME WRAP-AROUND FLURRIES OR SNOW SHOWERS WILL
BE POSSIBLE WEDNESDAY INTO THANKSGIVING DAY, BUT NO ACCUMULATION
IS EXPECTED AT THIS TIME.
COLDER AND DRY CONDITIONS ARE EXPECTED THROUGH AT LEAST FRIDAY,
BEFORE THE PATTERN BECOMES ACTIVE AGAIN HEADING INTO NEXT
WEEKEND. LOTS OF UNCERTAINTY AND A WIDE RANGE OF OUTCOMES AT
THIS DISTANCE, BUT IT WILL BE A TIMEFRAME TO KEEP AN EYE ON OVER
THE COMING WEEK.

BRING DRY CONDITIONS WITH MOSTLY SUNNY SKIES. WEST WINDS ARE
