DISCUSSION
ISSUED AT 338 AM CDT SUN MAR 30 2025
TODAY INTO TONIGHT:
WIDESPREAD FREEZING RAIN, SLEET, AND SNOW WERE OCCURRING EARLY
THIS MORNING ACROSS NORTHWEST WISCONSIN WITH MAINLY SNOW OVER
FAR NORTHWEST WISCONSIN INTO CENTRAL TO NORTHEAST MINNESOTA. FAR
NORTHERN MINNESOTA REMAINED DRY. THERE WAS A DRY SLOT WORKING
NORTH INTO SAWYER AND WESTERN PRICE COUNTY AS OF 0830Z. THE
SURFACE LOW WAS CENTERED IN CENTRAL IOWA AND IT WILL MOVE
NORTHEAST TODAY THROUGH SOUTHERN WISCONSIN INTO WEST TO
NORTHWEST LOWER MICHIGAN THIS EVENING. THE DRY SLOT WILL FILL
BACK IN WITH PRECIPITATION THIS MORNING AND CONTINUE THIS
AFTERNOON, MAINLY OVER NORTHWEST WISCONSIN AND FAR EASTERN
MINNESOTA AS AN AREA OF FGEN FORCING MOVES THROUGH WITH THE LOW
TO MID LEVEL LOW. PRECIPITATION TYPE WILL CONTINUE TO BE A
CHALLENGE, WITH MORE FREEZING RAIN AND OR SLEET OVER PRICE AND
SOUTHEAST SAWYER POSSIBLY INTO SOUTHERN IRON/ASHLAND THIS
MORNING. A CHANGE OVER TO ALL SNOW WILL OCCUR NORTHWEST TO
SOUTHEAST THROUGH THE DAY THOUGH, TAKING UNTIL LATE
AFTERNOON/EARLY EVENING FOR SOUTHEAST PRICE COUNTY. WE WILL KEEP
ALL THE WARNINGS AND ADVISORIES IN TACT FOR NOW. WE THOUGHT
ABOUT MOVING UP THE EXPIRATION FOR CROW WING/AITKIN BUT WILL LET
IT CONTINUE FOR NOW AS ADDITIONAL SNOWFALL THERE OF A HALF TO
1.5" IS POSSIBLE. ADDITIONAL ICE A GLAZE TO AS MUCH AS A HALF
INCH IS ALSO EXPECTED FROM BURNETT COUNTY EAST THROUGH WASHBURN,
SAWYER, PRICE AND SOUTHERN IRON/ASHLAND COUNTIES. THE HIGHEST
AMOUNTS WILL OCCUR OVER PRICE COUNTY WHERE THE ICE STORM WARNING
REMAINS IN EFFECT. ICE STORM WARNING LEVEL ICE ACCUMULATIONS
MAY OCCUR OVER PARTS OF SOUTHERN WASHBURN AND SAWYER COUNTIES
BUT THOSE AMOUNTS WILL BE MORE LIMITED IN COVERAGE AND ARE
HANDLED IN THE WINTER STORM WARNING.
COVERAGE OF SNOW WILL DECREASE THIS AFTERNOON INTO THE EVENING
FROM WEST TO EAST THROUGH EASTERN MINNESOTA INTO NORTHWEST
WISCONSIN.
DRY CONDITIONS WILL THEN DEVELOP TONIGHT AND OCCUR INTO MONDAY.
HIGHS MONDAY WILL BE FROM 30 TO AROUND 40 DEGREES, HIGHEST OVER
THE BRAINERD LAKES REGION. MOST AREAS WILL SEE MOSTLY SUNNY
SKIES ON MONDAY AIDING IN MELTING SOME OF THE SNOW AND ICE.
TUESDAY THROUGH WEDNESDAY NIGHT:
ANY DRY WEATHER WILL BE SHORT-LIVED WITH YET ANOTHER STORM
FORECAST TO AFFECT THE REGION LATER TUESDAY INTO AT LEAST
WEDNESDAY NIGHT.
THE DETERMINISTIC AND ENSEMBLE MODELS REMAIN CONSISTENT IN
MOVING A COLORADO LOW INTO OR NEAR THE NORTHLAND WEDNESDAY WITH
IT DEPARTING WEDNESDAY NIGHT INTO THURSDAY. THIS LOW HAS THE
POTENTIAL TO BE ON THE STRONGER SIDE WITH THE EC AND NAEFS
FORECASTING A STRONG LOW WITH ITS PRESSURE IN THE 0.5-1ST
PERCENTILE. THE ECMWF ENSEMBLE LOW LOCATIONS FOR 00Z THURSDAY
INDICATE QUITE A BIT OF SPREAD IN THE LOW TRACK BUT THERE ARE
MANY OF THE SOLUTIONS STILL FORECASTING SIGNIFICANT IMPACTS TO
THE NORTHLAND. THE 07Z SUN NBM STILL HAS A LARGE AREA OF 50%+
PROBABILITIES FOR SNOWFALL OF 6" OR MORE. THE ECMWF EFI AND SOT
VALUES SUPPORT THE POTENTIAL OF THIS BEING A SIGNIFICANT
SNOWFALL PRODUCER. BEFORE YOU SNOW LOVERS GET TOO EXCITED
THOUGH, THERE ARE LOW TRACKS THAT WOULD BE TOO FAR WEST AND A
FEW TOO FAR EAST FOR WIDESPREAD HEAVY SNOW BUT THE BOTTOM LINE
IS THERE IS POTENTIAL FOR HEAVY SNOWFALL FOR PORTIONS OF THE
NORTHLAND.
LATE WEEK:
THE PATTERN FINALLY FAVORS LESS ACTIVE WEATHER WITH BETTER
CHANCES FOR DRY CONDITIONS. UPPER RIDGING IS FORECAST ALONG THE
PACIFIC NW COAST PUTTING THE NORTHLAND UNDER NORTHERLY FLOW
ALOFT WITH COLDER AIR MOVING IN LATE WEEKEND.
AVIATION /12Z TAFS THROUGH 12Z MONDAY/
ISSUED AT 637 AM CDT SUN MAR 30 2025
A STORM SYSTEM WILL CONTINUE TO AFFECT MAINLY THE SOUTHEAST HALF
OF THE NORTHLAND WITH SNOW, SOME SLEET, AND FREEZING RAIN. THE
FREEZING RAIN AND SLEET WILL BE MOST LIKELY OVER PORTIONS OF
NORTHWEST WISCONSIN, POSSIBLY AFFECTING HYR BUT MORE LIKELY
SOUTHEAST OF THERE. CEILINGS WILL BE MVFR OR IFR WITH THE
VISIBILITY DROPPING TO IFR AT TIMES. MOSTLY VFR CONDITIONS ARE
EXPECTED OVER FAR NORTHERN MINNESOTA INCLUDING INL/HIB. THE
PRECIPITATION WILL TAPER OFF THEN END WEST TO EAST THIS
AFTERNOON INTO THIS EVENING.
GUSTY EAST TO NORTHEAST WINDS WILL BACK TO NORTHERLY TONIGHT AND
DIMINISH.
MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/
