426 AM CDT TUE APR 1 2025
KEY MESSAGES
- A QUICK HIT OF ACCUMULATING SNOW IS EXPECTED THIS EVENING
ACROSS CENTRAL WISCONSIN. MODERATE RATES MAY RESULT IN TRAVEL
IMPACTS MAINLY NORTH OF I-94.
- THUNDERSTORMS LATE TONIGHT INTO EARLY WEDNESDAY MORNING MAY
PRODUCE HAIL. ADDITIONAL STORMS ARE POSSIBLE WEDNESDAY
AFTERNOON WITH AN ASSOCIATED SEVERE RISK, *IF* ENOUGH
INSTABILITY IS ABLE TO FORM. UNCERTAINTY REMAINS WITH THIS.
- RELATIVELY COOL AND QUIET WEATHER EXPECTED FOR THE END OF THE
WEEK INTO THE WEEKEND.
SHORT TERM
ISSUED 426 AM CDT TUE APR 1 2025
TODAY THROUGH WEDNESDAY:
CLOUDS WILL GRADUALLY INCREASE TODAY AHEAD OF APPROACHING LOW
PRESSURE. BELOW NORMAL TEMPERATURES ARE EXPECTED ONCE AGAIN,
WITH HIGHS NOT GETTING OUT OF THE 40S. THIS WILL SET THE STAGE
FOR A QUICK BURST OF SNOW LATE AFTERNOON INTO THE EVENING
HOURS, AS TEMPERATURES COOL QUICKLY DUE TO EAST WINDS OFF THE
LAKE, THE LOSS OF DAYTIME HEATING, AND THE ONSET OF
PRECIPITATION. LIGHT ACCUMULATIONS WILL BE POSSIBLE (GENERALLY
UNDER AN INCH) NORTH OF I-94.
AFTER A VERY BRIEF LULL IN PRECIPITATION, RAIN SHOWERS ARE
EXPECTED TO MOVE IN FROM THE SOUTH LATE EVENING INTO THE NIGHT
AS STRONG WARM ADVECTION KICKS IN AHEAD OF AN APPROACHING LOW.
COULD SEE ENOUGH INSTABILITY BY LATE IN THE NIGHT FOR A FEW
THUNDERSTORMS, WITH SOME HAIL NOT OUT OF THE QUESTION. THIS
ROUND OF PRECIP WILL LIKELY MOVE OUT BY MID-MORNING WEDNESDAY,
WITH ATTENTION THEN TURNING TO THE POTENTIAL FOR MORE STORMS
LATE MORNING INTO THE AFTERNOON AS THE WARM SECTOR OF THE LOW
POKES INTO SOUTHERN WISCONSIN. THE BIG QUESTION REMAINS IF
THERE WILL BE ENOUGH INSTABILITY FOR STRONGER STORMS AS THE COLD
FRONT APPROACHES, WITH MORE THAN ENOUGH SHEAR FOR ORGANIZED
STORMS. THERE ARE DEFINITELY MIXED SIGNALS AMONG MODELS WITH
THE AFTERNOON STORM POTENTIAL, SOME SO UNCERTAINTY REMAINS.

LONG TERM
ISSUED 426 AM CDT TUE APR 1 2025
THURSDAY THROUGH MONDAY:
GENERALLY QUIET WEATHER IS EXPECTED LATE WEEK INTO EARLY NEXT
WEEK. A SHORT WAVE LATE WEEK INTO THE WEEKEND MAY BRING PRECIP
CHANCES TO THE AREA, BUT THE MAJORITY OF MODEL SOLUTIONS LOOK
DRY FOR MUCH OF THIS PERIOD. TEMPERATURES WILL BE NEAR NORMAL
THU THROUGH SAT, FALL BACK BELOW NORMAL BY EARLY NEXT WEEK.

AVIATION
ISSUED 426 AM CDT TUE APR 1 2025
CLOUDS WILL GRADUALLY INCREASE TODAY AHEAD OF AN APPROACHING
LOW, WITH VFR CEILINGS PERSISTING THROUGH THE AFTERNOON HOURS. A
QUICK ROUND OF SNOW IS LIKELY TO DEVELOP BY EARLY EVENING, WITH
UP TO AN INCH POSSIBLE, MAINLY NORTH OF I-94. THE SNOW MAY ONLY
STICK TO GRASSY AND ELEVATED SURFACES UNLESS THE RATES ARE
BRIEFLY HIGH ENOUGH. SNOW SHOULD MELT BY EARLY WEDNESDAY MORNING
AS TEMPERATURES RISE UNDER SOUTHERLY WINDS. RAIN SHOWERS WILL
MOVE IN FROM THE SOUTH LATER TONIGHT INTO WEDNESDAY MORNING,
WITH A FEW THUNDERSTORMS ALSO POSSIBLE. A COUPLE OF THE STORMS
COULD PRODUCE SOME HAIL AS WELL.
MORE SHOWERS AND STORMS WILL BE POSSIBLE LATER WEDNESDAY MORNING
INTO THE AFTERNOON, THOUGH THERE IS LESS CONFIDENCE IN THIS
ROUND OF PRECIP. IF STORMS DO DEVELOP, THERE WILL BE A POTENTIAL
FOR SOME OF THE STORMS TO BECOME SEVERE.
BREEZY SOUTHEAST WINDS TODAY WILL PICK UP THIS EVENING INTO
TONIGHT, WITH GUSTS OF 30 TO 35 KNOTS LIKELY. DESPITE THE HIGHER
WINDS A THE SURFACE, A PERIOD OF LOW LEVEL WIND SHEAR MIGHT
STILL BE POSSIBLE GIVEN STRONG WINDS ALOFT.
LOWER CEILINGS AND VISIBILITIES ARE POSSIBLE WITH THE SNOW LATER
TODAY, WITH LOW CEILINGS LIKELY TONIGHT INTO WEDNESDAY AS THE
RAIN SHOWERS MOVE THROUGH.
