DISCUSSION
ISSUED AT 204 PM CST TUE FEB 24 2026
THE CLIPPER SYSTEM THAT BROUGHT A BRIEF ROUND OF HEAVY SNOWFALL
RATES TO THE NORTHLAND IS RAPIDLY EXITING TO THE EAST THIS
AFTERNOON. WHILE THE ACCUMULATING SNOW HAS ENDED AND ALL WINTER
WEATHER ADVISORIES HAVE BEEN CANCELLED, A FEW LINGERING LIGHT
SNOW SHOWERS AND PATCHES OF FREEZING DRIZZLE MAY STILL PERSIST
FOR THE REST OF THE DAY, PARTICULARLY ACROSS THE ARROWHEAD AND
NORTHWEST WISCONSIN. GUSTY WEST WINDS WILL CONTINUE THIS
AFTERNOON BEFORE SHIFTING TO THE NORTHWEST TONIGHT AS A STRONG
PUSH OF COLD CANADIAN AIR FILTERS INTO THE AREA. SKIES WILL
GRADUALLY CLEAR, ALLOWING ACTUAL TEMPERATURES TO DROP BELOW ZERO
FOR MOST LOCATIONS. THIS WILL RESULT IN COLD WIND CHILLS
RANGING FROM 15 TO 25 BELOW ZERO BY WEDNESDAY MORNING.
HIGH PRESSURE SETTLES OVERHEAD FOR A QUIET BUT CHILLY WEDNESDAY,
WITH HIGH TEMPERATURES CONFINED TO THE TEENS. THIS COLD SNAP WILL
BE SHORT LIVED AS A BROAD RIDGE BEGINS TO BUILD ACROSS THE CENTRAL
UNITED STATES, BRINGING A NOTICEABLE WARMING TREND TO OUR REGION
FOR THE LATTER HALF OF THE WORK WEEK. BY THURSDAY, HIGHS WILL
CLIMB BACK INTO THE UPPER 30S, AND WE COULD SEE SOME LIGHT SNOW
BRUSH OUR NORTHERN ZONES AS A WEAK CLIPPER PASSES.
FRIDAY WILL BE THE WARMEST DAY OF THE WEEK WITH HIGHS PEAKING IN
THE UPPER 30S TO MID 40S WHICH MEANS THERE MAY BE FOG OVER THE
COLD SNOW PACK. HOWEVER, A SHARP COLD FRONT WILL SWEEP OUT OF
CANADA BY FRIDAY AFTERNOON. THIS FRONT WILL BRING A SIGNIFICANT
UPTICK IN WINDS, WITH STRONG WEST TO NORTHWEST WINDS GUSTING 30
TO 40 MPH OVER LAND MAYBE EVEN UP TO 55 MPH ALONG THE NORTH
SHORE. THERE IS ALSO A SLIGHT CHANCE FOR SNOW SQUALLS ALONG THIS
FRONTAL PASSAGE WITH STEEP LAPSE RATES THOUGH MOST OF OUR AREA
SHOULD BE RATHER DRY DESPITE THE INTENSITY OF THIS DEVELOPING
SYSTEM SOUTH OF HUDSON BAY - THE EXCEPTION MAY BE COOK COUNTY
WHERE THERE'S A BETTER CHANCE TO GET CLIPPED BY THIS LARGER
HIGHLY BAROCLINIC SYSTEM. BEHIND THE FRONT, AN ARCTIC AIRMASS
WILL PLUNGE SOUTHWARD, KNOCKING OUR TEMPERATURES WELL BELOW
NORMAL FOR SATURDAY AND SUNDAY - PROBABLY MORE THAN 15 DEGREES
BELOW NORMAL.
AVIATION /00Z TAFS THROUGH 00Z THURSDAY/

LINGERING AREAS OF MVFR CEILINGS WILL SLOWLY IMPROVE TO VFR
OVERNIGHT. A FEW SNOW SHOWERS MAY LINGER IN SPOTS THIS EVENING
AND MAY BRIEFLY BRING LOWER VISIBILITIES. WEST TO NORTHWEST
WINDS WILL REMAIN GUSTY OVERNIGHT BEFORE DIMINISHING AFTER
SUNRISE WEDNESDAY AS HIGH PRESSURE BUILDS IN. VFR CONDITIONS
WILL THEN PREVAIL FOR THE REMAINDER OF THE PERIOD.

8 FEET ARE EXPECTED AROUND THE OUTER APOSTLE ISLANDS, WHERE A
