SHORT TERM
ISSUED 1228 AM CST SUN FEB 8 2026
TODAY AND TONIGHT:
LOW LEVEL WARM AIR ADVECTION IS UNDERWAY AND TEMPERATURES ARE
NOT EXPECTED TO DROP MUCH EARLY THIS MORNING, DESPITE THE LOW CLOUDS
GRADUALLY CLEARING FROM WEST TO EAST. TEMPERATURES WILL HOVER IN
THE LOWER 20S AND THEN RISE INTO MID TO UPPER 30S ACROSS MOST OF
SOUTHERN WI BY LATE AFTERNOON.
THERE WAS A PRIOR MENTION OF A FREEZING RAIN CHANCE TOWARD
CENTRAL WI FOR THIS AFTERNOON, BUT UPSTREAM OBS AND FORECAST RH
AND PROFILES SUGGEST THAT THERE WILL BE TOO MUCH DRY AIR FOR
RAIN TO REACH THE GROUND. IT IS LOOKING MORE LIKE VIRGA, SO WE
KEEP THE FORECAST DRY FOR NOW.
A STRONG LOW LEVEL JET WILL REINFORCE THE MILD AIR OVER SRN WI
DURING THE OVERNIGHT HOURS. LOWS TONIGHT WILL ONLY DROP INTO THE
LOWER 30S, EXCEPT UPPER 20S TOWARD CENTRAL WI.
THE COMBINATION OF WEAK VORTICITY ADVECTION, WARM AIR ADVECTION,
AND SOME POOLING OF LOW LEVEL MOISTURE AHEAD OF AN APPROACHING
SURFACE TROUGH WILL LEAD TO SOME LOW CLOUDS DEVELOPING
OVERNIGHT. ICE CRYSTAL DEVELOPMENT IS NOT LIKELY, SO THERE WAS A
DISCUSSION ABOUT THE POTENTIAL FOR FREEZING DRIZZLE. HOWEVER,
THE MOISTURE AND FORCING APPEAR TO BE DISJOINTED AND WE KEPT THE
FORECAST DRY AT THIS TIME.

LONG TERM
ISSUED 1228 AM CST SUN FEB 8 2026
TUESDAY THROUGH SATURDAY:
TEMPERATURES WILL BE VERY MILD TO START THE DAY TUESDAY. LOW
PRESSURE CROSSING ONTARIO WILL PUSH AN ASSOCIATED SURFACE TROUGH
THROUGH SOUTHEAST WI DURING THE MORNING. COLD ADVECTION IS
EXPECTED TO DOMINATE WITH BRISK WNW WINDS SO TEMPERATURES WILL NOT
MAKE MUCH UPWARD PROGRESS DURING THE DAY. SOUTHERN WI WILL REMAIN
IN WEAK CYCLONIC FLOW WEDNESDAY AND UNDER HIGH PRESSURE WED NT.
CLOUDS ARE EXPECTED TO LINGER IN EAST CENTRAL WI WED AND KEEP
TEMPS JUST BELOW FREEZING THERE. MEANWHILE, WEAK WARM ADVECTION
MAY NOSE INTO SOUTHWEST WI AND BRING HIGH TEMPERATURES BRIEFLY
INTO THE MID 30S. CLEAR AND CALM CONDITIONS WED NT WILL ALLOW
TEMPS TO DROP INTO THE TEENS FOR MOST OF SOUTHERN WI.
A WEAK SHORTWAVE TROUGH CROSSING THE UPPER MIDWEST MAY BRING A
SWATH OF LIGHT SNOW TO WEST CENTRAL AND PORTIONS OF SOUTHERN WI
ON THURSDAY. HOWEVER, THE FOCUS FOR PRECIP LOOKS LIKE IT WILL
SHIFT TOWARD IA/MO/IL BY THU AFTERNOON/EVENING, WITH THE STUFF
OVER SRN WI DRYING UP OR AT LEAST LOSING ITS FORCING. ONCE THE
FOCUS SHIFTS SOUTH OF WI, WE SHOULD BE DRY FROM FRIDAY NIGHT
THROUGH THE WEEKEND WITH HIGH PRESSURE OVER THE GREAT LAKES.
TEMPERATURES LOOK TO GRADUALLY RISE THROUGH THIS PERIOD, WITH MOST
AFTERNOONS REACHING ABOVE FREEZING, AND WITH LOWS EACH NIGHT IN
THE 20S. THIS IS ABOVE NORMAL FOR THIS TIME OF YEAR.
TEMPERATURE SPREAD IN MODELS: NOT SURPRISING, TUESDAY HAS A BROAD
DISTRIBUTION OF MAX TEMPS BETWEEN THE MODELS, WITH A HIGHER
PROBABILITY IN THE WARMER RANGE. THE CURRENT FORECAST IS MORE
TOWARD THE 75TH PERCENTILE AND MAY NEED TO BE LOWERED WITH
SUBSEQUENT FORECASTS. THE MAXT PROBABILITY FOR WED IS CLEARLY
SHOWING A BIMODAL DISTRIBUTION AND THE CURRENT GRIDDED FORECAST
LIES IN THE MEAN, WHICH IS AROUND THE 70TH PERCENTILE. THIS IS DUE
TO THE FRONT BISECTING OUR FORECAST AREA AND IS SHOWING THE TWO
SCENARIOS DEPENDING ON WHERE THAT FRONT ACTUALLY ENDS UP. THU ALSO
HAS A BIMODAL DISTRIBUTION, BUT TO A MUCH LESSER EXTENT AND THE
CURRENT FORECAST IS LEANING TOWARD THE WARMER SIDE IN THE 75TH
PERCENTILE.

AVIATION
ISSUED 1228 AM CST SUN FEB 8 2026
THE STRATUS IS ERODING AWAY FROM THE WESTERN EDGE WHICH IS NEAR
LONE ROCK. EXPECT THE DRY AIR TO KEEP ERODING THIS STRATUS DECK
FROM WEST TO EAST THROUGH DAYBREAK. STRATUS MAY LINGER TOWARD
SHEBOYGAN THROUGH MID MORNING BEFORE CLEARING, BUT TRENDS
INDICATE THAT THE CLEARING WILL START TO SPEED UP. MVFR CIGS
AROUND 2000 FT ARE LINGERING OVER SBM AS WELL, BUT HAVE BECOME
VFR ELSEWHERE.
HIGH CLOUDS ARE EXPECTED THROUGH THE DAY. STRONG WARM AIR
ADVECTION WILL KICK IN THIS EVENING WHICH WILL PRODUCE LOW LEVEL
WIND SHEAR AT ALL TERMINALS. EARLY TUESDAY MORNING, LOW CEILINGS
ARE EXPECTED TO WORK THEIR WAY INTO SOUTHERN WI BEHIND A COLD
FRONT.
CRONCE
MARINE
ISSUED 1228 AM CST SUN FEB 8 2026
BRISK SOUTHERLY WINDS WILL PERSIST OVER LAKE MICHIGAN OVERNIGHT

ONTARIO. STEADY SOUTHEAST WINDS WILL BUILD MARGINALLY HIGH WAVES
IN THE NEARSHORE ZONES NORTH OF PORT WASHINGTON TONIGHT AND A
SMALL CRAFT ADVISORY IS IN EFFECT UNTIL MID MORNING.
THE ASSOCIATED SURFACE TROUGH WILL CROSS LAKE MICHIGAN
