DISCUSSION
ISSUED AT 256 PM CST MON NOV 24 2025
TODAY THROUGH WEDNESDAY...A POTENT STORM IS EXPECTED TO
INTENSIFY AS IT MOVES ACROSS THE AREA ON TUESDAY. AS THIS
STORM STRENGTHENS, RAIN WILL CHANGE OVER TO SNOW, AND NORTHERLY
WINDS WILL INCREASE. THE WORST CONDITIONS WILL SPREAD FROM WEST
TO EAST, TUESDAY EVENING AND OVERNIGHT, WITH TRAVEL IMPACTS
LINGERING INTO WEDNESDAY.
A WINTER STORM WARNING HAS BEEN ISSUED FOR DOUGLAS, TODD,
MORRISON, MILLE LACS, AND KANABEC WHERE CONFIDENCE HAS
INCREASED IN HEAVY SNOW AND STRONG WINDS LEADING TO BLOWING
SNOW. A WINTER STORM WATCH REMAINS FOR STEVENS, POPE, STEARNS,
AND BENTON COUNTIES, WHERE CONFIDENCE IS NOT HIGH ENOUGH YET TO
UPGRADE TO A WARNING. EXPECT AT LEAST ADVISORY LEVEL IMPACTS FOR
THESE COUNTIES. AREAS SOUTH AND EAST OF THE WATCH AND WARNINGS
WILL STILL HAVE TRAVEL IMPACTS EVEN THOUGH SNOW AMOUNTS WON'T BE
AS HIGH. A BROAD WINTER WEATHER ADVISORY HAS BEEN ISSUED TO
COVER POTENTIAL FOR A FEW INCHES OF SNOWFALL AND BLOWING SNOW
CONCERNS. ADDITIONALLY, A WIND ADVISORY HAS BEEN ISSUED FOR
PORTIONS OF SOUTHWEST AND SOUTH-CENTRAL MINNESOTA WHERE LESS
SNOWFALL IS EXPECTED, BUT STRONG WINDS WILL STILL DEVELOP.
ISOLATED IMPACTS FROM BLOWING SNOW WILL BE POSSIBLE WITHIN THE
WIND ADVISORY.
THE SYSTEM THAT WILL BRING A SIGNIFICANT CHANGE IN THE WEATHER
IS CURRENTLY LOCATED OVER THE IDAHO PANHANDLE, ON THE NORTHERN
EDGE OF A STRONG UPPER LEVEL JET. THERE IS A LARGE STRIP OF
POSITIVE VORTICITY EXTENDING UPSTREAM ALONG THE COAST OF BRITISH
COLUMBIA, AND OVER THE NEXT 24 HOURS, THIS STRIP OF POSITIVE
VORTICITY IS GOING TO CONGEAL INTO A COMPACT UPPER LEVEL
SHORTWAVE TROUGH. THE POSITIVE VORTICITY ADVECTION AND HEIGHT
FALLS AHEAD OF THIS TROUGH WILL LEAD TO SIGNIFICANT UPPER LEVEL
FORCING FOR ASCENT, AS EVIDENT BY THE SURFACE LOW DROPPING FROM
1007MB THIS EVENING, INTO THE UPPER 990S BY TUESDAY EVENING. AS
MENTIONED IN THE PREVIOUS DISCUSSION, A TROWAL WILL DEVELOP
NORTHWEST OF THIS SURFACE LOW, WITH HEAVY SNOWFALL EXPECTED.
MEANWHILE, NORTHERLY WINDS WILL INCREASE WITH GUSTS OF 40 TO 45
MPH. THE COMBINATION OF FALLING SNOW AND STRONG WIN WILL LEAD TO
LOW VISIBILITY. LASTLY, TEMPERATURES WILL START OUT WARM, WHICH
SHOULD ALLOW FOR SOME MELTING SNOW EARLY, BUT COLD AIR
ADVECTION AND SUB-FREEZING TEMPERATURES SHOULD LEAD TO
ACCUMULATING SNOW FAIRLY QUICKLY AFTER IT CHANGES OVER FROM RAIN
TO SNOW. OVERNIGHT TEMPERATURES WILL CONTINUE TO FALL, AND BY
WEDNESDAY MORNING AREAS IN WESTERN MINNESOTA WILL BE NEAR 20
DEGREES, WITH MID- 20S ELSEWHERE. THE CONCERN IS THAT ANY
UNTREATED SURFACES WILL FREEZE, LEADING TO SLIPPERY ROADS AND
SLOW WINTER TRAVEL CONDITIONS LASTING THROUGH WEDNESDAY MORNING,
WELL AFTER THE SNOW HAS ENDED. FORTUNATELY HIGHS ON WEDNESDAY
WILL BE IN THE MID TO UPPER 20S, SO THE MAIN ROADS SHOULD
RECOVER QUICKLY.
THURSDAY THROUGH THE WEEKEND... THURSDAY COULD STILL BE BREEZY
TO START THE DAY, WITH GUSTS UP TO 25 MPH, THOUGH THE PRESSURE
GRADIENT WILL LOOSEN AS THE SURFACE LOW CONTINUES INTO EASTERN
CANADA. PERSISTENT NORTHWEST WINDS WILL KEEP US COLD FOR SEVERAL
DAYS. HIGHS WILL REMAIN IN THE LOW TO MID 20S, WITH LOWS IN THE
TEENS EACH MORNING. FRIDAY MORNING LOOKS TO BE THE COLDEST WITH
THE NBM SUGGESTING SINGLE DIGITS FOR MUCH OF WESTERN AND INTO
CENTRAL MINNESOTA. FEELS LIKE TEMPERATURES WILL BE ABOUT 5 TO 10
DEGREES BELOW AIR TEMPERATURES WHEN WINDS PICK UP DURING THE
AFTERNOON, ESPECIALLY ON THURSDAY WHILE WINDS ARE STILL BREEZY.
SEVERAL LONG RANGE MODELS SHOW THAT THE REGION REMAINS PRIMED
FOR ADDITIONAL ACTIVITY THROUGH THE WEEKEND AND INTO THE EARLY
PART OF NEXT WEEK. THE UPPER LEVEL PATTERN EXHIBITS A POSITIVE
TILTED TROUGH EXTENDING FROM CENTRAL CANADA ALL THE WAY DOWN
TOWARDS SOUTHERN CALIFORNIA. SEVERAL LOWS COULD FORM OFF OF THE
ROCKIES AND TRACK THROUGH THE CENTRAL US. THERE IS UNCERTAINTY
IN WHERE THOSE SYSTEMS WOULD TRACK, THOUGH THERE IS INCREASING
SIGNAL FOR SNOW ACROSS PORTIONS OF SOUTHERN MINNESOTA FRIDAY
INTO SATURDAY (30-50% POPS). THE LATEST NBM HAS AT LEAST 15-35
PERCENT POPS STARTING FRIDAY EVENING AND LASTING ALL THE WAY
THROUGH MONDAY, WHICH SEEMS REASONABLE UNTIL WE CAN HONE IN WITH
HIGHER CONFIDENCE WHEN AND WHERE ANY SYSTEMS DEVELOP.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1143 AM CST MON NOV 24 2025
LITTLE BIT OF A MESSY START TO THE 24/18Z TAF SET DUE TO SUCH
VARIETY IN CLOUD COVER, PARTICULARLY CEILINGS. VISIBLE
SATELLITE IMAGERY SHOWS CLOUD COVER ACROSS ALL 7 TAF SITES
(LEAST AT AXN) BUT THE CEILINGS ARE LOWEST OVER EASTERN/SOUTHERN
MN INTO WESTERN WI, SUCH THAT IFR CONDITIONS ARE IN PLACE, WITH
CONDITIONS IMPROVING OVER CENTRAL-WESTERN MN. OVERALL, CEILINGS
WILL BE MAINTAINED FROM TONIGHT ONWARD FOR ALL SITES WITH
MAINLY MVFR TONIGHT FOLLOWED BY IFR CONDITIONS TOMORROW,
PARTICULARLY AS PRECIPITATION SETS IN. PRECIP WILL START OUT AS
RAIN FOR ALL SITES OVERNIGHT THROUGH TOMORROW, THEN THE ONLY
SITE WHICH TRANSITIONS TO -SN PRIOR TO 18Z TOMORROW IS AXN.
HOWEVER, GOING BEYOND 18Z TOMORROW, PARTICULARLY INTO TUESDAY
EVENING, SITES FROM WEST TO EAST WILL SEE THE STEADY TRANSITION
FROM -RA TO -SN BUT THIS TIMING WILL BE ADDRESSED IN LATER TAFS.
THE OTHER CONCERN WILL BE AN APPRECIABLE UPTICK IN WIND SPEEDS
AS THE DAY PROGRESSES WITH THE MOVEMENT OF THE LOW/FRONTS ACROSS
THE REGION. AFTER LIGHT/VARIABLE WINDS THROUGH THE EARLY
MORNING HOURS, WINDS WILL INCREASE FROM THE N TO NW TO SPEEDS
AROUND 13G22KT BY MID-TO-LATE DAY TOMORROW.
KMSP...MVFR CEILINGS AT THE START TO REMAIN IN PLACE THROUGH
LATE TUESDAY MORNING THEN WILL DROP TO IFR LEVELS FOR THE
REMAINDER OF THE DAY. MAY SEE CEILINGS COME UP TO AROUND 2 KFT
THIS EVENING THROUGH TONIGHT BEFORE DROPPING BACK UNDER.
PRECIPITATION LIKELY TO START AROUND 18Z BUT COULD HAVE SOME
REPORTABLE -SHRA PRIOR TO 18Z. RAINFALL IS EXPECTED TO THEN
BECOME STEADY TUESDAY AFTERNOON-EVENING WITH VISIBILITY DROPPING
BELOW 6SM. LIGHT/VARIABLE WINDS THROUGH THE OVERNIGHT HOURS WILL
HAVE A NEGLIGIBLE IMPACT ON RUNWAY CONFIGURATION BUT WITH WINDS
INCREASING IN SPEED FROM THE NW, A SWAP TO THE 30S LOOKS TO BE
IN THE CARDS FROM LATE TUESDAY MORNING ONWARD.
/OUTLOOK FOR KMSP/
WED...MVFR/IFR CEILINGS. -SHSN EARLY. WIND NW 15-25G30-35KTS.
