DISCUSSION
ISSUED AT 152 PM CST SUN DEC 21 2025
SURFACE HIGH PRESSURE IS MOVING ACROSS THE MIDWEST TODAY,
PROVIDING A QUIET AND PLEASANT BREAK FOR THE NORTHLAND. WHILE
TEMPERATURES REMAIN IN THE TEENS AND TWENTIES, THE LACK OF
SIGNIFICANT WIND MAKES FOR RELATIVELY WARMER CONDITIONS FOR ANY
OUTDOOR ACTIVITIES COMPARED TO YESTERDAY. AS THE HIGH PRESSURE
SHIFTS SOUTHEAST THIS AFTERNOON, SOUTHERLY WINDS WILL RETURN,
ALONG WITH WARMING TEMPERATURES.
CONDITIONS WILL CHANGE LATE TONIGHT AS A WARM FRONT LIFTS INTO THE
REGION. THIS SYSTEM BRINGS A COMPLICATED MIX OF PRECIPITATION
TYPES. FOR THE BRAINERD LAKES AND MILLE LACS AREAS, A LAYER OF
WARM AIR ALOFT MAY LEAD TO A BRIEF WINDOW OF FREEZING RAIN IN
THE OVERNIGHT HOURS EARLY MONDAY. EVEN A LIGHT GLAZE OF ICE CAN
MAKE THE MONDAY MORNING COMMUTE HAZARDOUS. FURTHER EAST INTO
NORTHWEST WISCONSIN, COLDER AIR WILL BE MORE ESTABLISHED,
RESULTING IN MAINLY LIGHT SNOW. TOTAL SNOW ACCUMULATIONS WILL
GENERALLY STAY UNDER AN INCH.
THE WARM FRONT WILL BE QUICKLY FOLLOWED BY A SECOND SYSTEM THAT
WILL SKIRT TO THE NORTH ACROSS CANADA. THE BORDERLANDS WILL ALSO
RECEIVE A TRACE TO AN INCH OF SNOW MONDAY NIGHT INTO TUESDAY.
THE WEATHER REMAINS RELATIVELY QUIET FOR THE MIDDLE OF THE WEEK,
BUT WE ARE CLOSELY MONITORING A POTENTIAL STORM SYSTEM FOR THE
CHRISTMAS HOLIDAY. FORECAST GUIDANCE THAT MADE A SIGNIFICANT
SHIFT LAST NIGHT TO SHOW A STRONGER WEATHER SYSTEM MOVING
THROUGH THE REGION THURSDAY AND FRIDAY HAS PERSISTED, INCREASING
CHANCES IN A MIX OF SNOW AND RAIN TO THE NORTHLAND. UNCERTAINTY
IS STILL HIGH ON THE TRACK AND TIMING OF THE SYSTEM, BUT MODELS
ARE STARTING TO AGREE ON ITS ARRIVAL ON CHRISTMAS
AFTERNOON/EVENING AND LAST INTO FRIDAY. IF THIS TREND CONTINUES,
THIS WILL POTENTIALLY DISRUPT HOLIDAY TRAVEL. TEMPERATURES ON
CHRISTMAS DAY WILL BE NOTABLY MILD, WITH AREAS SOUTH OF HIGHWAY
2 REACHING THE MID TO UPPER 30S, WHILE THE IRON RANGE AND
BORDERLANDS STAY IN THE MID TO UPPER 20S.
AVIATION /06Z TAFS THROUGH 06Z TUESDAY/
ISSUED AT 1124 PM CST SUN DEC 21 2025
ALL VFR CONDITIONS SHOULD CONTINUE AT ALL TERMINALS THROUGH SUNRISE.
HYR WILL BE ON THE EDGE OF SOME POSSIBLE PRECIPITATION THIS MORNING
THAT MAY DROP VISIBILITIES AND CEILINGS FOR SEVERAL HOURS BEFORE
CONDITIONS RETURN TO VFR BY LATE MORNING. AT INL, LIGHT SNOW AND
POSSIBLE FREEZING DRIZZLE MOVES INTO THE AREA MONDAY EVENING, BRING
MVFR TO IFR CEILINGS AND VISIBILITIES. VFR CONDITIONS ARE EXPECTED
AT BRD, HIB, AND DLH THROUGH THE TAF PERIOD. WINDS SHOULD BE FAIRLY
LIGHT THROUGH THE FORECAST OUT OF THE SOUTH-SOUTHEAST.
MARINE
ISSUED AT 152 PM CST SUN DEC 21 2025
SOUTHWEST WINDS OF 5 TO 10 KNOTS WILL PERSIST THROUGH THIS
EVENING ON WESTERN LAKE SUPERIOR. WINDS BACK TO THE EAST ON
MONDAY BUT STAY LIGHT. HAZARDOUS CONDITIONS FOR SMALL VESSELS
ARE POSSIBLE ON TUESDAY AS NORTHWEST WINDS INCREASE UP TO 30 KTS
ACROSS WESTERN LAKE SUPERIOR.
