DISCUSSION
ISSUED AT 313 AM CST WED MAR 4 2026
A WEAK FRONT IS CURRENTLY STALLED ACROSS THE NORTHLAND,
BRINGING WIDESPREAD LOW CLOUDS AND AREAS OF FOG EARLY THIS
MORNING. SOME LOCATIONS, MAINLY ALONG AND NORTH OF THE IRON
RANGE ARE SEEING VISIBILITY VALUES BELOW ONE MILE AS OF 3 AM.
WHILE VISIBILITIES IMPROVE DURING THE DAY TODAY, THE FRONT WILL
LINGER THROUGH THURSDAY. UNSEASONABLY WARM AIR CONTINUES TO MOVE
IN ALOFT, WHICH COMBINED WITH MELTING SNOW ON THE GROUND, WILL
KEEP MOISTURE TRAPPED NEAR THE SURFACE. THIS MAKES FOG VERY
LIKELY AGAIN TONIGHT AND THROUGH THURSDAY NIGHT FOR MOST OF THE
REGION.
DAYTIME TEMPERATURES WILL STAY QUITE MILD TODAY AND THURSDAY,
WITH HIGHS REACHING THE 40S AND 50S. HOWEVER, AREAS ALONG THE
NORTH SHORE WILL BE MUCH COOLER ON THURSDAY AS WINDS TURN TO THE
NORTHEAST, PULLING CHILLY AIR OFF LAKE SUPERIOR.
THE WEATHER TURNS MUCH MORE ACTIVE LATE THURSDAY NIGHT THROUGH
FRIDAY AS A STRONG LOW PRESSURE MOVES FROM WHERE IT DEVELOPS IN
COLORADO ACROSS NEBRASKA INTO IOWA ON FRIDAY, THEN NORTHEAST
ACROSS WISCONSIN FRIDAY NIGHT. EXPECT WIDESPREAD RAIN TO SPREAD
ACROSS THE AREA BEGINNING EARLY FRIDAY MORNING, WITH MODERATE
RAINFALL AMOUNTS OF UP TO THREE QUARTERS OF AN INCH POSSIBLE IN
NORTHWEST WISCONSIN AND EASTERN MINNESOTA. WE ARE ALSO
MONITORING THE POTENTIAL FOR SOME RUMBLES OF THUNDER, MAINLY
SOUTH OF THE IRON RANGE. AS COLDER AIR ARRIVES FRIDAY NIGHT, THE
RAIN WILL TRANSITION TO A WINTRY MIX AND EVENTUALLY LIGHT SNOW.
WHILE SIGNIFICANT SNOW ACCUMULATION IS NOT CURRENTLY EXPECTED,
SLICK TRAVEL IS POSSIBLE HEADING INTO SATURDAY. SNOWFALL AMOUNTS
WILL BE GREATEST OVER NORTHERN MINNESOTA, WHERE 1 TO 3 INCHES
IS CURRENTLY FORECAST.
ANOTHER SPRING SYSTEM WILL MOVE ACROSS THE AREA MONDAY THROUGH
WEDNESDAY OF NEXT WEEK. AHEAD OF IT, WARM AIR WILL HELP BOOST
TEMPERATURES WELL ABOVE NORMAL ON SUNDAY AND MONDAY.
PRECIPITATION CHANCES ARE CURRENTLY HIGHEST MONDAY NIGHT INTO
TUESDAY AS A FAIRLY STRONG LOW PRESSURE SYSTEM MOVES ACROSS THE
MID MISSISSIPPI RIVER VALLEY. CURRENTLY THERE IS A LOT OF SPREAD
IN TIMING AND TRACK BETWEEN INDIVIDUAL MODELS, MAKING THE
SIGNAL NOT VERY CLEAR IN THE ENSEMBLES.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1134 PM CST TUE MAR 3 2026
SATELLITE SHOWS IFR/LIFR STRATUS DECK EXPANDING ACROSS NORTH CENTRAL
MN. WITH THE ABUNDANCE OF MELTING SNOW WE SAW TODAY DEWPOINTS REMAIN
MOIST ENOUGH TO SUPPORT THE DEVELOPMENT OF FOG. BOTH THE FOG AND
STRATUS WILL LIKELY LINGER THROUGH THE MORNING HOURS BEFORE
GIVING WAY TO SOME BRIEF VFR CONDITIONS IN THE AFTERNOON. EXPECT
FOR INL WHERE THEY MAY BE LOCKED INTO STRATUS THROUGH THE DAY.
TOMORROW EVENING LOOKS TO BE SIMILAR WITH STRATUS AND FOG ONCE
AGAIN DEVELOPING AND EXPANDING ACROSS THE REGION.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 313 AM CST WED MAR 4 2026
EXPECT RELATIVELY QUIET CONDITIONS FOR TODAY WITH WAVES UNDER 2
FEET. HOWEVER, NORTHEAST WINDS WILL INCREASE TONIGHT INTO
THURSDAY TO 20 TO 25 KNOTS WITH GUSTS UP TO 30 KNOTS. WAVES WILL
BUILD TO 2 TO 4 FEET, ESPECIALLY ALONG THE NORTH SHORE AND THE
TWIN PORTS. SMALL CRAFT ADVISORIES WILL LIKELY BE NEEDED
STARTING TONIGHT AND CONTINUING THROUGH THURSDAY. WIND SPEEDS
AND WAVES DECREASE WHILE REMAINING OUT OF THE NORTHEAST THURSDAY
NIGHT, THEN REMAINING UNDER 10 KNOTS THROUGH FRIDAY.
