KEY MESSAGES
- DANGEROUSLY COLD WIND CHILLS TO 60 BELOW ZERO WILL CONTINUE
THROUGH SUNDAY MORNING. THE COLDEST PERIOD WILL BE TONIGHT INTO
FRIDAY MORNING.
UPDATE
ISSUED AT 957 PM CST THU JAN 22 2026
DANGEROUS COLD CONTINUES THIS EVENING WITH THE FREQUENCY OF SNOW
SHOWERS DIMINISHING WITH TIME. THERE IS ANOTHER WEAK WAVE COMING
DOWN FROM CANADA THAT MAY BRING ADDITIONAL FLURRIES BUT THE
BIGGEST THREAT WILL CONTINUE TO BE THE -50 TO -60 WIND CHILLS.
AS SUCH, NO MAJOR CHANGES TO THE FORECAST HERE.
UPDATE
ISSUED AT 644 PM CST THU JAN 22 2026
IT IS INDEED DANGEROUSLY COLD. WIND CHILLS ACROSS THE REGION
HAVE FALLEN INTO THE -40S AND -50S AND WILL CONTINUE TO HOVER
AROUND THERE THROUGH THE OVERNIGHT HOURS. THIS WILL PRESENT
A MAJOR RISK FOR HYPOTHERMIA FOR THOSE CAUGHT OUT WITHOUT
ADEQUATE PROTECTION. OTHER THAN THAT, AREAS OF LIGHT SNOW MAY
CONTINUE TO REDUCE VISIBILITY BUT WILL PRESENT A VERY LIMITED
IMPACT IN COMPARISON TO THE WIND CHILLS. A LIGHT DUSTING IS THE
MOST LIKELY OUTCOME OF ACCUMULATIONS SHOULD ANY ARISE.
DISCUSSION

..SYNOPSIS
AN ARCTIC AIRMASS IS IN PLACE OVER THE FA, AND WILL REMAIN IN CHARGE
THROUGH EARLY FRIDAY. THE SURFACE HIGH RESPONSIBLE WILL TRACK SOUTH
AND EAST, REACHING SOUTHERN MN BY FRIDAY NIGHT. ON ITS HEELS,
ANOTHER AREA OF HIGH PRESSURE WORKS DOWN OUT OF SASKATCHEWAN. THIS
WILL AGAIN BRING A PERIOD OF EXTREMELY COLD WEATHER SATURDAY NIGHT
THROUGH MONDAY. THEREAFTER, NORTHWEST FLOW DOES NOT LOOK TO
BUDGE, LEAVING US RIDING A WAVERING BAROCLINIC ZONE. AS THE JET
NUDGES NORTH AND EAST TOWARDS THE MIDDLE OF NEXT WEEK, WE WILL
WARM UP. HOWEVER, THERE ARE HINTS WITHIN ENSEMBLE GUIDANCE OF A
CLIPPER TYPE SYSTEM WORKING THROUGH THE REGION AROUND WEDNESDAY,
BUT PREDICTABILITY IN ITS EVOLUTION IS LOW AT THIS TIME. IT
DOES SEEM REGARDLESS OF HOW THIS WAVE PLAYS OUT, COLDER AIR WILL
FILTER BACK IN AS THE JET/BAROCLINIC ZONE DRIFTS BACK TO THE
SOUTH AND WEST THROUGH THE END OF THE FORECAST PERIOD.
..COLD THROUGH THE WEEKEND
IN THE WAKE OF THE ARCTIC FRONT THAT BARRELED THROUGH LAST NIGHT,
TEMPERATURES HAVE WENT FROM COLD TO COLDER. TAKE THE TEMPERATURES
HERE AT THE WFO FOR EXAMPLE. AT 6AM, WE WERE AT -9F, FELL TO -16F BY
10AM, AND HAVE SINCE STAYED STUCK AT -17F. WIND CHILLS VARY FROM -35
IN THE SOUTH TO -55 NEAR THE CANADIAN BORDER. THERE WILL BE NO
IMPROVEMENT THROUGH THE REST OF THE AFTERNOON. TONIGHT INTO FRIDAY
MORNING WILL BE THE COLDEST PERIOD OF THIS COLD SNAP. WIND CHILL
VALUES OF -45 TO -60 ARE EXPECTED AREA WIDE. THEREAFTER, AS THE CENTER
OF HIGH PRESSURE WORKS THROUGH, WINDS WILL DECREASE. THIS WILL AT
LEAST IMPROVE WIND CHILL VALUES MIDDAY FRIDAY INTO SATURDAY
MORNING. THERE WILL BE A BIT OF A BREAK IN THE WORST OF THE COLD
WEATHER SATURDAY AFTERNOON, BEFORE THE PREVIOUSLY MENTIONED
SECOND HIGH COMES THROUGH TO END THE WEEKEND. TEMPERATURES WILL
AGAIN FALL, WITH SATURDAY NIGHT BRINGING EXTREME COLD TO THOSE
NORTH OF I-94 WITH WIND CHILLS AS LOW AS -50.
THEREFORE, WE HAVE WENT AHEAD AND UPGRADED THE EXTREME COLD WATCH TO
AN EXTREME COLD WARNING FOR AREAS ALONG AND NORTH OF I-94 THROUGH
SUNDAY AT NOON. FOR AREAS TO THE SOUTH, THE EXTREME COLD WARNING
REMAINS IN EFFECT THROUGH 3PM FRIDAY, THEREAFTER CONVERTING TO A
COLD WEATHER ADVISORY. WHILE THERE WILL BE A PERIOD SATURDAY
AFTERNOON WHERE LOCATIONS MAY BRIEFLY GET ABOVE CRITERIA, THE MAIN
MESSAGE IS THAT IT IS COLD, AND A CONSISTENT HEADLINE THROUGH SUNDAY
MORNING BEST TELLS THAT STORY. IT SHOULD BE NOTED THAT SUNDAY NIGHT
LOOKS TO BE ANOTHER PERIOD WHERE A COLD WEATHER HEADLINE OF SOME
SORT WILL BE NEEDED. AT THIS TIME, WE DID NOT ISSUE ANYTHING TO
COVER THIS CONSIDERING IT IS DAY 3 INTO DAY 4 OF THE FORECAST, BUT
IT IS SOMETHING FUTURE SHIFTS WILL NEED TO DETERMINE.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

AT THIS TIME. WINDS WILL GENERALLY REMAIN LIGHT WITH NO CHANGES
