DISCUSSION
ISSUED AT 305 AM CST MON FEB 23 2026
OUR WORK WEEK FORECAST BEGINS ON A MOSTLY CLEAR, COLD, AND QUIET
NOTE ACROSS SOUTH CENTRAL MN AND MOST OF WESTERN WI. 3AM
TEMPERATURES RANGE BETWEEN -6 AT AXN TO 10 AT EAU. LINGERING LOW
STRATUS, TIED TO A NE 925/850MB FETCH OFF OF LAKE SUPERIOR, BLANKETS
THE SKIES OVER RUSK, CHIPPEWA, & EAU CLAIRE COUNTIES IN WI AND IS
SUPPORTING SLOW COOLING. SOME UNCERTAINTY EXISTS IN HOW SOON THE
STRATUS WILL SCATTER OUT OF THOSE WESTERN WI COUNTIES, THOUGH THE
EASTWARD ADVANCE OF RIDGING SHOULD TURN THE MID-LEVEL FETCH MORE
NORTHERLY AND FLUSH THE STRATUS EAST LATER THIS MORNING. OTHERWISE,
TODAY APPEARS PARTLY TO MOSTLY SUNNY AND QUIET AS SURFACE HIGH
PRESSURE BUILDS ACROSS THE UPPER MIDWEST. LITTLE CHANGE IN THE
AIR MASS WILL SUPPORT ANOTHER DAY OF BELOW NORMAL TEMPERATURES.
AFTERNOON HIGHS ARE FORECAST TO RANGE BETWEEN 15-20 DEGREES OR
SO.
A MORE ACTIVE PICTURE SETS UP THIS WEEK AS A ~160KT JET STREAK
TRANSLATES EAST ACROSS THE INTERNATIONAL BORDER. THE INITIAL SYSTEM
TO WATCH WILL BE A CLIPPER THAT IS FORECAST TO TAKE SHAPE ON THE
NOSE OF THE JET TONIGHT OVER SASKATCHEWAN/MANITOBA. LITTLE CHANGE IN
THE EXPECTED TRACK OF THE CLIPPER, WHICH IS PROGGED TO DRIFT
SOUTHEAST ACROSS NORTHERN MN INTO THE NORTHERN GREAT LAKES TUESDAY.
THIS TRACK PLACES THE MAJORITY OF OUR FORECAST AREA ON THE WARM SIDE
OF THE SYSTEM, WHICH IS REFLECTED BY THE EXPANSION OF A THERMAL
RIDGE, CHARACTERIZED BY +3-7C 925MB T'S, LATE TONIGHT INTO TUESDAY
MORNING. AS A RESULT, TUESDAY SHOULD FEEL QUITE A BIT WARMER, WITH
LATEST FORECAST HIGHS SET TO RANGE BETWEEN 35-40 DEGREES FOR MOST
LOCATIONS. MID 40S APPEAR POSSIBLE ALONG I-90. THE COOLEST
TEMPERATURES ARE FORECAST NORTH OF I-94 IN MN, WHERE HIGHS ARE SET
TO RUN CLOSER TO THE FREEZING MARK. GIVEN THE EXPECTED TRACK OF THE
CLIPPER, THE MAJORITY OF PRECIPITATION WILL FALL AS SNOW IN WFO
DLH'S FORECAST AREA. WITH THAT BEING SAID, ENSEMBLE MEANS SUPPORT A
FEW HUNDREDTHS OF LIQUID ALONG AND NORTH OF I-94 IN THE MPX CWA.
THERMAL PROFILES WITHIN THE WAA REGIME SUPPORT LIGHT MIXED
PRECIPITATION NEAR I-94 IN BOTH MN/WI AS THE CLIPPER SLIDES THROUGH.
FATHER NORTH, P-TYPE SHOULD BE ALL SNOW GIVEN A COOLER PROFILE &
PROXIMITY TO THE SURFACE LOW. IT'S THESE LOCATIONS (NORTHERN MILLE
LACS, KANABEC, POLK, BARRON, RUSK) THAT WILL HAVE THE BEST CHANCE OF
A HALF INCH TO INCH OF FRESH SNOW ACCUMULATION.
STRONG COLD ADVECTION TRAILING THE CLIPPER WILL USHER IN -5 TO -10C
850MB TEMPERATURE ANOMALIES HEADING INTO WEDNESDAY MORNING, WHICH
WILL YIELD A COLDER DAY WITH HIGHS IN THE UPPER TEENS TO LOWER 20S.
OUR ATTENTION TURNS TO THE SECOND HALF OF WEDNESDAY, WHEN THE NEXT
ROUND OF ACTIVE WEATHER (IN THE FORM OF LIGHT SNOW) WILL BE
POSSIBLE. BY WEDNESDAY, THE ACTIVE STORM TRACK WILL HAVE SHIFTED
SOUTH, WHICH PLACES OUR FORECAST AREA ON THE NORTHERN/COLD SIDE OF
THE NEXT WAVE. DRIVING PRECIPITATION CHANCES IS A SHORTWAVE THAT IS
FORECAST TO STRENGTHEN ACROSS CENTRAL PLAINS. GUIDANCE HAS BEEN
CONSISTENT IN A WNW TO SSE ORIENTED PRECIPITATION BAND ACROSS
EASTERN SD/SW MN INTO CENTRAL/NORTHERN IOWA. UNCERTAINTY IN THE
DEGREE OF WARM ADVECTION AND PLACEMENT OF A REMNANT BAROCLINIC ZONE
FOLLOWING TUESDAY'S CLIPPER HAVE RESULTED IN A LARGE SPREAD IN THE
POSITION AND INTENSITY OF THE BAND OF PRECIPITATION. HOWEVER, THERE
IS GROWING CONSENSUS ACROSS THE MODEL SUITE (INCLUDING MACHINE
LEARNING OUTPUT) THAT THE HEAVIEST QPF WILL SETUP TO THE SOUTHWEST
OF OUR FORECAST AREA. AS A RESULT, LIQUID PRECIPITATION AMOUNTS HAVE
COME DOWN A BIT AND POPS REMAIN IN THE 30-40 PERCENT RANGE WEDNESDAY
EVENING. PER THE BLENDED SOLUTION, LOCATIONS WITH THE BEST CHANCE
FOR AN INCH OR SO OF SNOW ACCUMULATION WILL BE ALONG I-90. SHOULD
THE LATEST SOUTHERLY TRENDS CONTINUE, POPS & QPF AMOUNTS WILL
UNDERGO FURTHER DECREASES.
THE UP AND DOWN TEMPERATURE TREND WILL TAKE A TURN IN THE WARMER
DIRECTION THURSDAY AND FRIDAY, AS AN EXPANSIVE THERMAL RIDGE BUILDS
ACROSS THE NORTHERN CONUS IN RESPONSE TO SURFACE LOW PRESSURE
DEEPENING OVER SOUTH CENTRAL CANADA. 850MB ANOMALIES OF 10-12C
ARE FORECAST TO OVERSPREAD THE REGION AND WILL SUPPORT HIGHS
CLIMBING INTO THE 40-50 DEGREE RANGE ON FRIDAY. MOST ENSEMBLE
MEMBERS KEEP QPF WELL TO THE NORTH OF THE FORECAST AREA, SO
WE'LL RUN WITH A DRY FORECAST. COLDER AIR RETURNS FOR THE
WEEKEND (HIGHS IN THE 20S) FOLLOWING A MAINLY DRY COLD FRONTAL
PASSAGE. LONG TERM GUIDANCE DEPICTS A SPRAWLED OUT BAROCLINIC
ZONE BENEATH UPPER ZONAL FLOW NEXT WEEKEND. MAY EVENTUALLY NEED
POP MENTIONS NEXT WEEKEND AS A SERIES OF WEAK PERTURBATIONS
ADVANCE WITHIN THE WESTERLY FLOW REGIME.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
ISSUED AT 530 AM CST MON FEB 23 2026
MVFR STRATUS OVER EAU HAS BEEN SLOW TO SCATTER OUT OVERNIGHT,
HOWEVER RECENT SATELLITE TRENDS DISPLAY SOME EROSION OF THE
WESTERN EDGE OF THE CLOUD BANK. TOOK THE TAF IN AN OPTIMISTIC
DIRECTION, AS CONTINUED DEGRADATION OF THE STRATUS SHOULD OCCUR
EARLY IN THE PERIOD. ALL OTHER SITES OPEN THE 12Z PERIOD WITH
SKC CONDITIONS. BACK TO THE NW, A BATCH OF VFR STRATUS ~10K FEET
IS MOVING SOUTHEAST OUT OF ND AND WILL LIKELY HOLD TOGETHER AS
IT DRIFTS ACROSS MN THIS MORNING. WINDS WILL TURN OUT OF THE
SOUTH LATER THIS MORNING AND INTO THIS AFTERNOON, WITH SPEEDS
BETWEEN 5-10KTS. WINDS WILL INCREASE THIS EVENING AHEAD OF AN
INCOMING CLIPPER THAT COULD PRODUCE LIGHT WINTRY PRECIPITATION AT
AREA TERMINALS TOMORROW. PRECIPITATION MENTION MAY BE WARRANTED
IN FORTHCOMING TAF PACKAGES.
