DISCUSSION
ISSUED AT 327 PM CST TUE JAN 27 2026
HIGH PRESSURE STRETCHED FROM THE CANADIAN PRAIRIES INTO THE
NORTHERN AND CENTRAL PLAINS EARLY THIS AFTERNOON WITH LOW
PRESSURE ALONG THE ONTARIO-QUEBEC BORDER BETWEEN JAMES BAY AND
LAKE HURON. THIS WAS SETTING UP A PRESSURE GRADIENT ACROSS THE
GREAT LAKES INTO MINNESOTA RESULTING IN GUSTY NORTHWEST WINDS
ACROSS THE REGION. THIS GRADIENT WILL SLACKEN A BIT TONIGHT AS
THE LOW MOVES FURTHER EASTWARD. GUSTS WILL LIKELY SUBSIDE, BUT
SUSTAINED WINDS WILL STILL BE AROUND 5 TO 15 MPH FOR MOST
LOCATIONS. WITH COLD AIR STILL IN PLACE, LOWS TONIGHT WILL DROP
INTO THE TEENS BELOW ZERO WITH WIND CHILLS IN THE 20S BELOW
ZERO. A FEW LOCATIONS MAY FALL INTO THE LOWER 30S BELOW ZERO,
BUT THIS IS NOT EXPECTED TO BE WIDESPREAD ENOUGH FOR ANY COLD
HEADLINES TONIGHT.
WITH THE PERSISTENT NORTHWESTERLY WINDS, LAKE-EFFECT
SNOW SHOWERS WILL CONTINUE ACROSS THE SOUTH SHORE IN NORTHWEST
WISCONSIN TONIGHT INTO FRIDAY. GIVEN THE COLD TEMPERATURES AND
BUILDING ICE ON LAKE SUPERIOR, THERE ISN'T MUCH FOR MOISTURE TO
WORK WITH, SO SNOW SHOWERS ARE EXPECTED TO BE LIGHT WITH
ACCUMULATIONS OF AROUND AN INCH OR LESS THROUGH FRIDAY. ISOLATED
HIGHER AMOUNTS WILL BE POSSIBLE ALONG THE STATE ROUTE 77
CORRIDOR IN NORTHERN IRON COUNTY.
GENERALLY NORTHWEST FLOW WILL PREVAIL THROUGH THE WEEK WITH HIGH
PRESSURE KEEPING THE CLIPPER TRAIN WELL TO OUR WEST.
TEMPERATURES WILL SLOWLY WARM THROUGH THE REMAINDER OF THE WEEK
WITH SINGLE DIGITS ABOVE ZERO FOR WEDNESDAY THROUGH FRIDAY
BEFORE REACHING INTO THE TEENS AND LOW 20S SATURDAY. NEAR NORMAL
TEMPERATURES IN THE LOW TO MIDDLE 20S WILL THEN BE SEEN FOR
SUNDAY INTO THE NEW WEEK. THERE WILL BE LOW CHANCE FOR SNOW
FRIDAY INTO FRIDAY NIGHT FROM THE ARROWHEAD INTO NORTHERN
WISCONSIN AS AN UPPER LOW AND TROUGH DROP SOUTHWARD ON THE
EASTERN PERIPHERY OF THE HIGH. THIS SYSTEM LOOKS MOISTURE
STARVED AND ANY ACCUMULATIONS WILL BE MINIMAL, IF ANY. A BETTER
CHANCE FOR SNOW WILL ARRIVE IN THE SUNDAY-MONDAY TIME FRAME IN
ASSOCIATION WITH A CLIPPER. MOISTURE AGAIN LOOKS TO BE LACKING
WITH THIS SYSTEM WITH CHANCES FOR AT LEAST AN INCH OF SNOW
REMAINING IN THE 15-30% RANGE WITH ABOUT A 40 TO 60% CHANCE FOR
AT LEAST A DUSTING OF SNOW.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1147 PM CST TUE JAN 27 2026
PREDOMINATELY VFR CONDITIONS UNDER A FEW HIGH CLOUDS FOR MOST OF
THE AREA UNTIL THIS MORNING. THE EXCEPTION IS FOR AN MVFR
STRATUS DECK MOVING INTO INL/THE INTERNATIONAL BORDER AS OF 06Z
THAT WILL GRADUALLY SINK SOUTH OVERNIGHT INTO THIS MORNING. HAVE
INTRODUCE BKN MVFR CEILINGS TO INL, HIB STARTING AT 08Z, DLH AT
11Z, AND HYR AT 16Z TO TRY AND TIME OUT THE SOUTHERN EXPANSION
OF THE MVFR CEILINGS. THERE IS SOME UNCERTAINTY ON HOW FAR THE
CLOUD DECK MOVES AND HOW DENSE THE COVERAGE WILL BE, ESPECIALLY
DURING THE MORNING AND AFTERNOON. FOR NOW, HAVE LEANED TOWARDS
BKN FOR THE DAYTIME HOURS TODAY FOR MOST TERMINALS. WE THEN HAVE
CLOUDS GOING SCATTERED STARTING THIS EVENING, BUT THERE IS STILL
A 30-40% CHANCE THAT MVFR CEILINGS COULD HANG AROUND THROUGH AT
LEAST THE END OF THE TAF PERIOD.
