BETWEEN 40-50+ MPH HAVE BEEN OBSERVED BOTH IN RADAR AND SURFACE

OF SOUTHEASTERN WISCONSIN. A SEVERE THUNDERSTORM WATCH REMAINS
IN EFFECT FOR AREAS SOUTH AND WEST OF MILWAUKEE UNTIL 11 PM.
HAVE MULTIPLE WAYS TO RECEIVE WARNING INFORMATION THROUGH LATE

SHORT TERM
ISSUED 354 PM CDT TUE JUN 3 2025
TONIGHT THROUGH WEDNESDAY:
THE FIRST ROUND OF STORMS ON THE LEADING EDGE OF THE DEEPER
MOISTURE HAS WEEKEND AND PUSHED EAST OF THE AREA. A BREAK IN
THE WIDESPREAD PRECIP HAS ALLOWED TEMPERATURES TO BEGIN TO
RECOVER ACROSS SOUTHWEST AND SOUTH-CENTRAL WISCONSIN. SHORT TERM
MODEL GUIDANCE SHOWS MODERATE RECOVERY OF INSTABILITY AS A
RESULT, WITH A CHANCE FOR ANOTHER ROUND OF STORMS AS THE NEXT
PUSH OF FORCING ASSOCIATED WITH A COLD FRONT MOVES IN FROM THE
WEST. THE MAIN THREATS WITH THESE STORMS LATER THIS AFTERNOON
INTO THE EVENING HOURS WILL BE STRONG WINDS ALONG WITH LOCALLY
HEAVY RAINFALL. GIVEN PRECIPITABLE WATER VALUES PUSHING 2 INCHES
AND THE FACT THAT THE FRONT WILL BE MOVING SLOWLY, REPEATED
ROUNDS OF SHOWERS AND STORMS MAY LEAD TO SOME HIGHER RAINFALL
TOTALS.
THUNDER CHANCES WILL WIND DOWN BY MIDNIGHT OR SO, WITH LINGERING
LIGHT TO MODERATE RAINS SHOWERS OVERNIGHT INTO EARLY WEDNESDAY
AS THE COLD FRONT GRADUALLY MOVES THROUGH. CLEARING SKIES
EXPECTED NORTHWEST TO SOUTHEAST DURING THE DAY TOMORROW, WITH
SOME AFTERNOON CUMULUS POSSIBLE WITHIN THE AREAS OF CLEARING.
WARMEST TEMPS TOMORROW WILL BE IN THE NORTHWEST WHERE A LONGER
PERIOD OF SUNSHINE IS EXPECTED, WITH COOLER CONDITIONS TOWARDS
THE SOUTHEAST. NORTHEAST WINDS NEAR THE LAKE WILL KEEP IT EVEN
COOLER IN THE FAR EAST.
THE HIGH SWIM RISK CONTINUES INTO THIS EVENING FROM RACINE
COUNTY NORTHWARD. LIFE THREATENING WAVES AND CURRENTS ARE
EXPECTED. STAY OUT OF THE WATER, AND STAY AWAY FROM DANGEROUS
AREAS LIKE PIERS AND BREAKWALLS.

A LINE OF +SHRA & EMBEDDED +TSRA CONTINUES TO PROGRESS EAST ACROSS
THE REGION THIS EVENING, BRINGING REDUCED VIS READINGS &
OCCASIONALLY GUSTY WINDS TO SOUTHERN WISCONSIN TERMINALS. HAVE TIMED
THE LINE OF PRECIP OUT BASED ON RADAR TRENDS, AND WILL CONTINUE TO

POSSIBLE BEHIND THE AFOREMENTIONED LINE OF +SHRA/+TSRA, WITH -SHRA
GRADUALLY OVERSPREADING ALL FIELDS THROUGH THE REMAINDER OF THE
OVERNIGHT PERIOD. THE STEADY -SHRA WILL GRADUALLY REDUCE VIS & CIG
READINGS, WITH IFR ANTICIPATED AT ALL AERODROMES BY THE PREDAWN

NEEDED. PRECIP WILL GRADUALLY TAPER FROM WEST TO EAST WEDNESDAY
MORNING, ALLOWING FLIGHT CATEGORIES TO IMPROVE FROM LATE MORNING
