AFTER A CLOUDY START TO THE DAY WITH PATCHY FOG AND FREEZING
DRIZZLE, CONDITIONS EARLY THIS AFTERNOON HAVE BEEN MUCH QUIETER
AS A WARM FRONT ASSOCIATED WITH AN APPROACHING CLIPPER MOVES
THROUGH THE CWA. TEMPERATURES ACROSS THE WESTERN HALF OF THE CWA
ARE EXPECTED TO WARM ABOVE FREEZING THIS AFTERNOON WITH HIGHS
AROUND THE MID 30S. IN THE EASTERN HALF OF THE CWA, HIGH TEMPS
THIS AFTERNOON WILL LIKELY BE AT OR SLIGHTLY BELOW FREEZING AS
THE WARM FRONT WON'T BE PASSING THROUGH UNTIL AFTER PEAK DIURNAL
HEATING.
THE MAIN FOCUS IN THE NEAR TERM IS A SECOND ROUND OF WINTRY
PRECIPITATION THAT WILL BE ARRIVING THIS EVENING INTO TONIGHT AS
A COLD FRONT AND MID-LEVEL DISTURBANCE MOVES THROUGH THE CWA.
THIS SECOND ROUND OF PRECIP IS EXPECTED TO HAVE A MESSY VARIETY
OF PRECIPITATION TYPES. WHILE SNOW WILL BE THE DOMINANT PRECIP
TYPE, ABOVE-FREEZING TEMPS ARE LIKELY TO INITIALLY CAUSE A
RAIN/SNOW MIX. IN ADDITION, LIGHT FREEZING RAIN IS POSSIBLE AS
WARM AIR ALOFT OCCURS FROM THE I-35 CORRIDOR TO ST. CROIX RIVER
VALLEY WITH SUB- FREEZING SFC TEMPS. EXPECT PRECIP TYPE TO
TRANSITION TO ALL SNOW LATE TONIGHT INTO EARLY FRIDAY MORNING AS
CAA OCCURS BEHIND THE COLD FRONT.
TOTAL SNOW AMOUNTS FOR THE VAST MAJORITY OF THE CWA TODAY
THROUGH FRIDAY WILL BE LIGHT FROM A TRACE TO 2". LOCALLY HIGHER
AMOUNTS AROUND 3" ARE EXPECTED IN THE SNOW BELTS OF IRON COUNTY
AND EASTERN ASHLAND COUNTY AS SLIGHT LAKE EFFECT SNOW BEGINS
WITH THE NORTH- NORTHWEST FLOW BEHIND THE COLD FRONT. MARGINAL
DELTA-TS BETWEEN 850MB AND THE SFC OF AROUND 14-16 DEGC AND THE
INCREASED ICE COVER WILL LIMIT THE INTENSITY OF LAKE EFFECT. IN
TERMS OF ICE ACCUMULATIONS, THE MOST LIKELY AREA FOR A FEW
HUNDREDTHS OF AN INCH OF ICE WILL BE PINE AND BURNETT COUNTIES
WITH A GLAZE POSSIBLE ELSEWHERE.
FOLLOWING THE DEPARTURE OF THIS LATE WEEK CLIPPER ON FRIDAY
MORNING, CLOUD COVER WILL DECREASE ON FRIDAY. WITH CLEAR SKIES
EXPECTED ON FRIDAY NIGHT, TEMPERATURES WILL BE COLD WITH LOWS
DROPPING INTO THE NEGATIVE SINGLE DIGITS TO NEGATIVE TEENS. THE
SYNOPTIC PATTERN REMAINS UNSETTLED THIS WEEKEND INTO EARLY NEXT
WEEK AS ADDITIONAL CLIPPERS POTENTIALLY MOVE THROUGH WITH A
STRONG BAROCLINIC ZONE REMAINING OVER THE UPPER MIDWEST. THIS
TRANSLATES TO OFF-AND-ON WINTRY MIX PRECIP CHANCES FROM 20-40
PERCENT MULTIPLE TIMES SATURDAY ONWARD.
ADDITIONAL DAYS WITH HIGH TEMPS ABOVE FREEZING ARE FORECAST ON
MONDAY AND TUESDAY THIS UPCOMING WEEK, WITH MUCH OF THE CWA
SEEING HIGHS IN THE MID TO UPPER 30S. WHILE HIGH TEMPS DO COOL
BACK BELOW FREEZING ON WEDNESDAY, IT'S WORTH NOTING THAT THIS
WARMER THAN AVERAGE PATTERN IS LIKELY TO CONTINUE IN MID-
FEBRUARY AS THE CLIMATE PREDICTION CENTER HAS A 70-80% CHANCE
FOR ABOVE NORMAL TEMPERATURES. FOR CONTEXT, NORMAL TEMPERATURES
FOR MID-FEBRAURY ARE HIGHS AROUND THE MID 20S AND OVERNIGHT LOWS
IN THE SINGLE DIGITS.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1119 PM CST THU FEB 5 2026
MESSY MIX OF RAIN, SNOW AND FREEZING DRIZZLE PERSISTS OVER
NORTHWEST WISCONSIN FOR A FEW MORE HOURS BEFORE BECOMING ALL
LIGHT SNOWFALL INTO FRIDAY MORNING. EVEN BEHIND THE LIGHT WINTRY
MIX ONGOING, THERE WILL BE A PERIOD OF IFR PREVAILING CONDITIONS
AT EACH TERMINAL THROUGH 10-14Z TODAY. THESE IFR CONDITIONS WILL
ALSO SEE CONTINUED LIGHT SNOW SHOWERS PERIODICALLY. TRENDS IN
FORECAST GUIDANCE AND THE INCOMING AIRMASS FAVOR CEILINGS
LIFTING TO MVFR TOWARDS 12-15Z AND THEN SCOURING OUT FROM
NORTH TO SOUTH 15-18Z TODAY. THERE WILL BE SCATTERED MVFR
CEILINGS THOUGH LINGERING FROM DAYTIME CUMULUS CLOUDS,
ESPECIALLY IN NORTHERN MINNESOTA. NORTHWEST WINDS ARE FURTHER
SHIFTING TO THE NORTH BEHIND THE PRECIP SYSTEM AND WILL FURTHER
INCREASE IN SPEED 09-12Z THIS MORNING.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 318 PM CST THU FEB 5 2026
AFTER A BREEZY START THIS MORNING, QUIETER CONDITIONS HAVE BEEN
OCCURRING THIS AFTERNOON AHEAD OF AN APPROACHING COLD FRONT. THIS
LULL IN WINDS WILL BE SHORT-LIVED THOUGH AS NORTHWEST WINDS WILL BE
INCREASING LATE TONIGHT FOLLOWING THE COLD FRONTAL PASSAGE. WINDS OF
10-20 KNOTS WITH GUSTS OF 25-30 KNOTS ARE EXPECTED. SMALL CRAFT
ADVISORIES ARE IN EFFECT STARTING LATE TONIGHT. BRIEF GALES MAY BE
POSSIBLE AROUND THE 5 AM TO 10 AM TIMEFRAME ON FRIDAY MORNING ALONG
THE NORTH SHORE FROM SILVER BAY TO GRAND PORTAGE. HOWEVER, THE
POTENTIAL FOR GALES IS A LOW 20% CHANCE. EXPECT WINDS TO EASE BY
FRIDAY NIGHT AS HIGH PRESSURE BUILDS.
