FORECAST DISCUSSION FOR ROUTINE MORNING FORECAST ISSUANCE
KEY MESSAGES
- SLIPPERY CONDITIONS FROM LAST NIGHT'S SNOW AND PATCHY FREEZING
DRIZZLE MAY EXTEND INTO THIS MORNING'S COMMUTE, ESPECIALLY ON
UNTREATED SECONDARY ROADS.
- A CLIPPER SYSTEM MAY IMPACT THE AREA THURSDAY AND FRIDAY. THIS
SYSTEM HAS THE POTENTIAL TO BRING MINOR SNOW ACCUMULATIONS AND
GUSTY WINDS, FOLLOWED BY A BRIEF RETURN TO COLDER TEMPERATURES.
- HIGHS IN THE 20S WILL BE COMMON FOR MUCH OF THE WEEK, WITH THE
WARMEST DAYS OCCURRING THURSDAY AND MONDAY, WHEN SOME LOCATIONS
MAY REACH THE LOWER TO MIDDLE 30S.
DISCUSSION
ISSUED AT 252 AM CST MON FEB 2 2026
LIGHT SNOW OVER EASTERN WI WILL CONTINUE TO SHIFT EAST EARLY THIS
MORNING AS A SHORT-WAVE AND ASSOCIATED COLD FRONT MOVE OUT OF THE
REGION. SCATTERED LAKE-EFFECT SNOW SHOWERS WILL LINGER ACROSS FAR
NC WI DURING THE DAY, AND PROBABLY INTO TONIGHT. OTHERWISE
SCATTERED FLURRIES AND PATCHY FREEZING DRIZZLE (ACROSS THE FAR
SOUTH PART OF THE FORECAST AREA) SHOULD TAPER OFF AROUND DAYBREAK.
SLIPPERY ROADS FROM LAST NIGHT'S SNOW AND PATCHY FREEZING DRIZZLE
MAY LINGER INTO THE MORNING COMMUTE, ESPECIALLY ON ANY UNTREATED
SECONDARY ROADS. OVERCAST CONDITIONS SHOULD GIVE WAY TO A FEW
BREAKS AS THE DAY WEARS ON, AND THIS SHOULD HELP BOOST
TEMPERATURES INTO THE UPPER TEENS AND LOWER 20S NORTHWEST TO THE
MIDDLE TO UPPER 20S ELSEWHERE. MORE WIDESPREAD CLEARING OCCURS
TONIGHT, EXCEPT IN FAR NC WI, WHERE SOME LAKE-EFFECT CLOUDS
PERSIST. PARTLY CLOUDY SKIES AND LIGHT WINDS SHOULD ALLOW
TEMPERATURES TO DROP INTO THE SINGLE DIGITS ABOVE AND BELOW ZERO.
A PERIOD OF HIGH PRESSURE WILL BRING DRY CONDITIONS TUESDAY THROUGH
WEDNESDAY NIGHT AS THE UPPER-LEVEL PATTERN RE-AMPLIFIES. AN UPPER
RIDGE STRENGTHENS OVER THE WESTERN U.S. WHILE A MEAN TROUGH
REINFORCES ITSELF OVER THE EAST. THIS SET-UP WILL PAVE THE WAY FOR
ANOTHER CLIPPER SYSTEM THURSDAY INTO FRIDAY. MODEL TRENDS ARE
LEANING TOWARD A FARTHER NORTH TRACK THROUGH ONTARIO WITH THIS
SYSTEM; PERHAPS AS FAR NORTH AS HUDSON/JAMES BAYS. IF THIS OCCURS,
WOULD EXPECT LESS SNOW AND A BIT WARMER TEMPERATURES. GUSTY NW-N
WINDS WOULD STILL OCCUR ON FRIDAY, BUT WITH A LOWER CHANCE OF
GALES ON LAKE MICHIGAN.
TEMPERATURES REMAIN ON THE MILDER SIDE THROUGH MOST OF THE
PERIOD, WITH HIGHS MAINLY IN THE 20S, AND EVEN SOME LOWER TO
MIDDLE 30S IN C/EC WI THURSDAY AND MONDAY. A BRIEF SHOT OF BELOW
NORMAL TEMPERATURES ARRIVES IN THE WAKE OF THE LATE WEEK CLIPPER
SYSTEM, BUT TEMPERATURES SHOULD REBOUND A BIT BY THE END OF THE
WEEKEND.
AVIATION
FOR 06Z TAF ISSUANCE
ISSUED AT 1100 PM CST SUN FEB 1 2026
MAINLY MVFR CEILINGS AND VISIBILITIES WILL CONTINUE OVERNIGHT,
WITH POCKETS OF IFR CONDITIONS AT TIMES. THE FLURRIES AND LIGHT
SNOW WILL COME TO AN END FROM WEST TO EAST ACROSS MOST LOCATIONS
LATE THIS EVENING AND OVERNIGHT, POSSIBLY ENDING AS A BRIEF PERIOD
OF FREEZING DRIZZLE, AS A COLD FRONT AND LOW PRESSURE SYSTEM EXIT
THE REGION. HOWEVER, BETTER CHANCE OF SEEING THE FREEZING DRIZZLE
WILL BE ACROSS SOUTHERN WI (WHERE THE LOWER IFR AND LIFR CEILINGS
RESIDE), SO WILL NOT INCLUDE IN ANY TAF. NOT MUCH SNOW
ACCUMULATION IS EXPECTED, WITH TOTALS UP TO AROUND A HALF INCH IN
MOST LOCATIONS. A LIGHT GLAZE IS POSSIBLE WHERE THE FZDZ OCCURS.
CLOUDS LINGER INTO MONDAY AT TIMES, WITH DOWNSLOPING NORTHWEST
WINDS ALLOWING FOR A LEAST SOME PARTIAL CLEARING ACROSS CENTRAL
AND EASTERN WI, BUT SOME MID AND HIGH CLOUDS WILL ALSO BE
ARRIVING. SOME LIGHT LAKE EFFECT SNOW SHOWERS OR FLURRIES WILL
REMAIN POSSIBLE MAINLY OVER NORTH-CENTRAL WI DUE TO THE NORTHWEST
FLOW OVER LAKE SUPERIOR, POSSIBLY IMPACTING RHI.
SOUTH/SOUTHWEST WINDS THIS EVENING AHEAD OF THE FRONT WILL SHIFT
TO THE WEST/NORTHWEST OVERNIGHT INTO MONDAY MORNING REMAINING
UNDER ~10 KTS OR LESS.
GRB WATCHES/WARNINGS/ADVISORIES
NONE.
