CURRENT CONDITIONS/TODAY:
A WARM FRONT IS MOVING IN FROM THE WEST AND PRODUCING SOME LIGHT
SNOW SHOWERS ACROSS NORTHERN MN. THIS FRONTAL BOUNDARY IS SET TO
PROPAGATE THROUGH THE REGION TODAY WITH SNOW EXITING TO OUR EAST BY
THE AFTERNOON. THIS FORECAST PACKAGE HAS MADE A FEW EDITS IN THE
NEAR TERM INCLUDING THE REDUCTION OF FREEZING DRIZZLE AS THE FRONT
DEPARTS. THE LATEST 00Z GUIDANCE THAT HAS COME IN SHOWS MUCH BETTER
SATURATION ALOFT THEN IN THE PREVIOUS RUNS WHICH LEANS INTO A
ALL SNOW SOLUTION. ONE INTERESTING SIGNAL THAT HAS DEVELOPED IN
THE HIGH RES GUIDANCE IS A CLUSTER OF SNOW SHOWERS MOVING OUT OF
THE RED RIVER VALLEY AND THROUGH NORTH CENTRAL MN INTO NW WI
BEHIND THE WARM FRONT. THE RAP WOULD SUGGEST THAT THESE WILL BE
FUELED BY A CORRIDOR OF ENHANCED 700MB FGEN. TO ACCOUNT FOR
THIS WE HAVE ADDED SOME 30% POPS ALONG ITS PATH THROUGH THE
MORNING HOURS. IMPACTS WITH THESE SNOW SHOWERS WILL BE JUST A
QUICK BURST OF SNOW THAT BRIEFLY REDUCES VISIBILITY. OVERALL,
LOW IMPACT SNOW THREAT TODAY WITH NORTHERN MN SEEING 0.5" TO 1"
OF SNOW ACCUMULATION AND A 0.5" OR LESS FOR NW WI.
FRIDAY:
A STRONG LOW PRESSURE SYSTEM IS SET TO MOVE ACROSS MANITOBA AND INTO
ONTARIO FRIDAY. IT'S ASSOCIATED PRECIPITATION SHIELD LOOKS TO
LARGELY MISS THE NORTHLAND BUT WE WILL STILL SEE SOME IMPACTFUL
WEATHER FROM THE TRAVELING LOW. THE PRESSURE GRADIENT WILL INCREASE
ACROSS THE NORTHLAND LEADING TO GUSTY WINDS. THE EFI FOR WIND GUSTS
ACROSS NORTHERN MN ARE AROUND 0.8 AND JUST ACROSS THE INTERNATIONAL
BORDER THEY ARE SITTING AROUND 0.9 WITH A SHIFT OF TAILS OF 1. EACH
OF THE LAST 3 MODEL RUNS HAS SEEN AN INCREASE IN THE POTENTIAL
WINDS. SOUNDING PROFILES SHOW DEEP MIXING WITH WIND SPEEDS AT THE
TOP OF THE INVERSION AROUND 50 MPH. SOME MOMENTUM WILL BE LOSS AS
IT GETS TRANSFERRED DOWN TO THE SURFACE BUT WIDESPREAD POTENTIAL FOR
WIND GUSTS OF 40 MPH LOOKS INCREASINGLY LIKELY, ESPECIALLY OVER
NORTHERN MN AND THE NORTH SHORE.
ONE OTHER IMPACT TO BE WEARY OF IS THE CHANCE FOR SNOW SQUALLS TO
DEVELOP IN THE AFTERNOON AND EVENING ACROSS NORTHERN MN AS THE
STRONG COLD FRONT ADVANCES SOUTHEAST. SURFACE INSTABILITY COULD BE
ON THE ORDER OF 50 J/KG WITH STEEP LAPSE RATES UP THROUGH 2 KM.
THE PARAMETER SPACE BECOME LESS FAVORABLE AS WE MOVE INTO THE
LATER EVENING HOURS AND THE FRONT MOVES INTO NW WI.
THE WEEKEND:
THE COLD FRONT WILL MOVE SOUTH OF THE REGION TO START THE WEEKEND
BEFORE ITS BAROCLINIC ZONE STALLS OUT OVER THE MIDWEST. WHILE
ACTIVITY CAN BE EXPECTED ALONG THIS ZONE THE NORTHLAND LOOKS TO BE
FAR ENOUGH NORTH AND UNDER THE INFLUENCE OF HIGH PRESSURE THAT WILL
MITIGATE OUR PRECIPITATION CHANCES. AT THIS TIME THERE ARE NO STRONG
SIGNALS FOR ANY IMPACTFUL WEATHER AS WE ROUND OUT THE WEEKEND AND
HEAD INTO NEXT WEEK.
TEMPERATURE ROLLER COASTER THROUGH THE WEEK:
WARMER TODAY WITH HIGHS CLIMBING INTO THE 30S AND LOW 40S. EVEN
WARMER TEMPERATURES FOR FRIDAY PRIOR TO THE ONSET OF A COLD FRONT IN
THE AFTERNOON. A STRONG COLD FRONT DIGS THROUGH THE NORTHLAND FROM
THE NORTH FRIDAY AFTERNOON AND WILL SEE TEMPERATURES BACK IN THE
SINGLE DIGITS AND TEENS FOR SATURDAY. FROM HERE WE WILL SEE ANOTHER
WARMING TREND, ALBEIT SLOWER THEN THE LAST ONE. LOOK FOR TEMPS TO
CREEP BACK INTO THE 30S BY EARLY NEXT WEEK AND GRADUALLY ASCEND TO
THE 40S BY MIDWEEK.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/

LAST OF THE WARM FRONT SNOW SHOWERS EXIT NORTHWEST WISCONSIN
OVER THE NEXT COUPLE OF HOURS. LINGERING MVFR SKY COVER IN FAR
NORTHERN MINNESOTA WILL PERSIST THOUGH INTO THE LATE AFTERNOON
HOURS AND POTENTIALLY EARLY EVENING. ANOTHER FEW HOUR PERIOD OF
LIGHT SNOWFALL IS POSSIBLE TONIGHT FOR NORTHERN MINNESOTA WITH A
PROB30 MOW IN PLACE FOR THE KINL TAF SITE. AHEAD OF AN INCOMING
COLD FRONT FRIDAY MIDDAY TO AFTERNOON, A PERIOD OF LOW LEVEL
WIND SHEAR IS EXPECTED LATE TONIGHT INTO FRIDAY MORNING BEFORE
GUSTY WESTERLY WINDS MIX OUT FROM 15 TO 18Z FRI.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 116 AM CST THU FEB 26 2026
LIGHT WINDS ACROSS THE WESTERN LAKE SUPERIOR TODAY AS A WARM FRONT
WORKS IN FROM THE WEST. FRIDAY, STRONG WINDS WILL RUSH ACROSS THE
WATERS ONCE AGAIN WITH GALES LIKELY. STORM FORCE WINDS WILL ALSO BE
POSSIBLE ALONG THE NORTH SHORE IN THE EVENING. WINDS WILL INITIALLY
BE OUT OF THE SOUTHWEST AND THEN TURN TO OUT OF THE NW FRIDAY
EVENING AS A COLD FRONT MOVES THROUGH.
