SHORT TERM
ISSUED 443 AM CST MON DEC 29 2025
TODAY THROUGH TONIGHT:
SNOWFALL APPEARS TO HAVE KEPT A SLIGHT INVERSION ALIVE THROUGH
THE OVERNIGHT HOURS ACROSS MUCH OF SOUTHERN WISCONSIN, WITH
WINDS FAILING TO REACH 40 MPH IN MOST AREAS. HOWEVER, AS SNOW
BEGINS TO TAPER OFF AND MORE DRY AIR IS ABLE TO WORK ITS WAY TO
THE SURFACE, EXPECTING HIGHER WIND GUSTS TO DEVELOP AND PERSIST
THROUGHOUT THE AFTERNOON HOURS. WIND ADVISORY REMAINS IN EFFECT
THROUGH NOON CST IN SOUTHWESTERN WISCONSIN AND THROUGH 6 PM CST
IN SOUTHEASTERN WISCONSIN.
SNOWFALL HAS A SHARP CUTOFF ACROSS NORTH-CENTRAL TO SOUTHWESTERN
WISCONSIN RIGHT NOW, WITH EXPECTATIONS FOR AN END TO STEADY
SNOWFALL FROM WEST TO EAST BETWEEN 6 AND 10 AM CST. AN INCH OR
TWO OF ADDITIONAL SNOW IS EXPECTED BEFORE ENDING ACROSS THE
AREA. SNOWFALL ON TOP OF WET ROADS FROM RAIN YESTERDAY WILL
MAKE FOR A SLICK MORNING COMMUTE ON UNTREATED ROADS, AND
BLOWING AND DRIFTING WITHIN AREAS OF HIGH WINDS MAY CONTINUE FOR
SEVERAL HOURS AFTER SNOWFALL ENDS. ALTHOUGH CONFIDENCE IS HIGH
IN VERY GUSTY WINDS THROUGH TODAY, SNOWPACK MAY BE TOO SHALLOW
TO PRODUCE CONSISTENT BLOWING SNOW, WHICH WOULD RESULT IN
VISIBILITIES REMAINING HIGH AND TRAVEL IMPACTS REMAINING
MINIMAL. IF THIS OCCURS, WINTER STORM WARNINGS AND WINTER
WEATHER ADVISORIES MAY BE CANCELED EARLY. HOWEVER, THIS WILL BE
DECIDED AS CONDITIONS WARRANT.
WINDS WILL SLOWLY DIMINISH THIS AFTERNOON THROUGH TONIGHT AS
STRONG LOW PRESSURE EXITS INTO QUEBEC, ALTHOUGH THEY WILL
REMAIN BREEZY. AS WINDS FALL BELOW WIND ADVISORY CRITERIA (45
MPH), ANY LINGERING BLOWING SNOW WILL ALSO END. EXPECTING LOWS
IN THE SINGLE DIGITS ABOVE ZERO TO THE LOW TEENS, WITH WIND
CHILLS IN THE SINGLE DIGITS BELOW ZERO.
