CENTRAL WISCONSIN THIS MORNING, AND MAY LINGER INTO THE

SHORT TERM
ISSUED 345 AM CDT WED SEP 10 2025
TODAY THROUGH TONIGHT:
ISOLATED TO SCATTERED SHOWERS SHOULD CONTINUE TO SLOWLY SHIFT
EAST INTO SOUTH CENTRAL WISCONSIN INTO THIS MORNING, AS THE MAIN
AREA OF DIFFERENTIAL CVA SHIFTS THROUGH. THERE IS DECENT
MOISTURE AT 700 MB AND ABOVE, WITH THE LOW LEVELS RATHER DRY PER
AREA FORECAST SOUNDINGS. THUS, SOME OF THE SHOWERS MAY EVAPORATE
BEFORE HITTING THE GROUND, WHICH LEADS TO MORE CONFIDENCE IN THE
ISOLATED TO SCATTERED WORDING IN THE FORECAST. A RUMBLE OF
THUNDER MAY OCCUR AS WELL, WITH VERY WEAK INSTABILITY PRESENT.
THIS AREA MAY SHIFT FURTHER EAST INTO PARTS OF SOUTHEAST AND
EAST CENTRAL WISCONSIN THIS AFTERNOON BEFORE ENDING, IF THE
MOISTURE AND UPWARD VERTICAL MOTION CAN REMAIN VIABLE ENOUGH TO
OVERCOME THE DRY LOW LEVELS. COULD SEE A RUMBLE OF THUNDER HERE
TOO, IF INSTABILITY DEVELOPS PER FORECAST SOUNDINGS.
OTHERWISE, MIDDLE TO HIGH CLOUDS SHOULD LINGER INTO TODAY, WITH
SOME DIURNAL CUMULUS CLOUDS ALSO DEVELOPING THIS AFTERNOON.
LIGHT SOUTH WINDS ARE EXPECTED TODAY, BECOMING SOUTHEAST NEAR
LAKE MICHIGAN THIS AFTERNOON WITH A LAKE BREEZE. HIGHS SHOULD
REACH THE MIDDLE 70S, WITH UPPER 70S IN SOUTHEAST WISCONSIN
BEFORE THE LAKE BREEZE PUSHES IN.
WINDS WILL WEAKEN TONIGHT WITH SOME PARTIAL CLEARING, WITH HIGH
PRESSURE TO THE NORTHEAST OF THE REGION. THERE IS SOME POTENTIAL
FOR FOG TO DEVELOP OVERNIGHT INTO EARLY THURSDAY MORNING GIVEN
THIS SETUP. HOWEVER, CONFIDENCE IS LOW, AS LOW TEMPERATURES IN
THE MIDDLE 50S OVER MOST AREAS MAY NOT GET LOWER THAN EXPECTED
DEW POINTS THIS AFTERNOON (LOWER TO MIDDLE 50S). THUS, MAY JUST
SEE SOME FOG IN THE LOW LYING AREAS. FOR NOW, WILL LEAVE OUT
MENTION IN THE FORECAST.

LONG TERM
ISSUED 345 AM CDT WED SEP 10 2025
THURSDAY THROUGH TUESDAY:
UPPER LEVEL RIDING IS EXPECTED TO BUILD IN FROM THE SOUTHWEST
LATE WEEK, WITH WARMING CONDITIONS AS SOUTHERLY LOW LEVEL FLOW
ALSO DEVELOPS. DRY WEATHER IS EXPECTED THURSDAY THROUGH THE DAY
FRIDAY, UNDER DEPARTING SURFACE HIGH PRESSURE.
MODELS ARE SHOWING A CHANCE FOR SHOWERS AND STORMS LATER FRIDAY
INTO EARLY SATURDAY, AS WARM AIR ADVECTION INCREASES AND A WEAK
WAVE ROLLS THROUGH THE TOP OF THE RIDGE. THERE REMAINS A GOOD
SIGNAL THAT HIGH TEMPS WILL HIT 80 DEGREES MOST PLACES FOR THE
FIRST TIME THIS MONTH BY FRIDAY.
THE LATEST ROUND OF MODELS HAVE COME INTO BETTER AGREEMENT FOR
THE WEEKEND INTO EARLY NEXT WEEK, COMPARED TO 24 HOURS AGO.
THERE IS FAIRLY GOOD CONSENSUS THAT UPPER LEVEL RIDGING WILL
REMAIN IN PLACE THROUGH THIS PERIOD, WITH MAINLY DRY WEATHER AND
ABOVE NORMAL TEMPERATURES EXPECTED.
