DISCUSSION
ISSUED AT 214 AM CST SAT JAN 24 2026
THE CORE OF THE ONGOING ARCTIC AIR MASS REMAINS ENTRENCHED OVER
THE NORTHLAND THIS MORNING, KEEPING THE REGION IN THE GRIP OF
DANGEROUS COLD. WIND CHILLS EARLY THIS MORNING HAVE BEEN
OBSERVED FROM 30 TO 45 BELOW ZERO AND AIR TEMPERATURES OF 25 TO
40 BELOW ZERO ARE BEING OBSERVED....CLOSER TO 15 TO 20 BELOW
ZERO FOR SHORELINE AREAS. WHILE HIGH PRESSURE TO OUR SOUTH
ALLOWS FOR SOME SUNSHINE TODAY, DAYTIME HIGH TEMPERATURES WILL
REMAIN IN THE SINGLE DIGITS BELOW ZERO. THE EXTREME COLD WARNING
STAYS IN EFFECT THROUGH NOON TODAY.
AS WE TRANSITION INTO THIS EVENING AND TONIGHT, THE AIR TEMPERATURE
WILL DROP RAPIDLY BACK TOWARD 20 TO 30 BELOW ZERO. WHILE WIND SPEEDS
ARE EXPECTED TO STAY CALM TO POCKETS OF LIGHT WIND, THE QUICKLY
RETURNING DANGEROUS COLD KEEPS THE COLD WEATHER ADVISORY IN
EFFECT BEGINNING AT 6 PM THIS EVENING. IF THE WIND FORECAST
INCREASES EVEN A FEW MPH THOUGH, THERE IS A SMALL POSSIBILITY
THAT PORTIONS OF NORTHWEST WISCONSIN COULD SEE CONDITIONS WORSEN
ENOUGH TO REQUIRE AN UPGRADE BACK TO A WARNING FOR NOW, THE
ADVISORY COVERS THE HAZARD WELL THROUGH SUNDAY MORNING.
IN TERMS OF SNOWFALL, THE WEATHER REMAINS RELATIVELY QUIET
INLAND, THOUGH A FLURRIES MAY DRIFT ACROSS NORTHERN MINNESOTA
LATER THIS AFTERNOON AS A WEAK DISTURBANCE MOVES IN FROM THE
NORTHWEST AND WINDS SHIFT FOR A SHORT PERIOD TO SOUTHWESTERLY.
THESE FLURRIES SHIFT SOUTH OF THE NORTHLAND EARLY TUESDAY
MORNING. THE MORE NOTABLE ACTIVITY THOUGH WILL BE A CONVERGENCE
BAND THAT PRESENTLY IS TARGETING THE BAYFIELD PENINSULA BUT IS
EXPECTED TO SHIFT TOWARD THE NORTH SHORE LATER TODAY. SOUTHERN
COOK COUNTY HAS ABOUT A 30 PERCENT CHANCE OF SEEING LESS THAN AN
INCH OF ACCUMULATION INTO THIS EVENING. BY TONIGHT, THIS BAND
WILL MIGRATE BACK TOWARD THE NORTHERN TIP OF THE BAYFIELD
PENINSULA AND PERSIST THERE THROUGH THE WEEKEND.
LOOKING TOWARD THE START OF THE WORK WEEK, WE WILL BEGIN TO SEE
A SLOW MODERATION IN TEMPERATURES. WHILE STILL BELOW NORMAL, THE
DAYTIME HIGHS WILL FINALLY START TO CLIMB INTO THE SINGLE DIGITS
ABOVE ZERO AND EVEN LOWER TEENS. A WEAK CLIPPER SYSTEM IS
FORECAST TO MOVE THROUGH MONDAY AFTERNOON INTO TUESDAY MORNING,
POTENTIALLY (20-40% CHANCE) BRINGING A DUSTING TO HALF-INCH OF
SYSTEM SNOW TO THE REGION. FOLLOWING THIS SYSTEM, THE EXTENDED
FORECAST APPEARS MOSTLY DRY AND QUIET OUTSIDE OF SOUTH SHORE
SNOWBELT LIGHT LAKE EFFECT SNOWFALL. OF NOTE THOUGH IS THAT THE
BELOW- NORMAL TEMPERATURE TREND WILL HANG ON FOR SEVERAL MORE
DAYS BEFORE NEAR TO...MAYBE...SLIGHTLY ABOVE NORMAL
TEMPERATURES ARRIVE IN EARLY FEBRUARY.
