UPDATE
ISSUED AT 808 PM CDT FRI JUN 13 2025
UPDATED POPS TONIGHT THROUGH SUNDAY MORNING. MODELS CONTINUE TO
SPREAD MEASURABLE PRECIPITATION TOO FAR NORTH, PARTICULARLY THE
NBM. A WEAK NOCTURNAL SOUTHERLY LOW-LEVEL JET IS FORECAST TO
DEVELOP TONIGHT AND STRENGTHEN MOISTURE FLUX INTO PINE, BURNETT,
WASHBURN, SAWYER, AND PRICE COUNTIES. THERE ARE ALREADY SIGNS
THE PRECIPITATION FROM WILLMAR, MN TO MEDFORD, WI IS ADVANCING
NORTHWARD. EXPECT THIS TREND TO CONTINUE THROUGH 08Z. RAIN
SHOWERS, AND PERHAPS A THUNDERSTORM OR TWO, WILL MOVE INTO
SOUTHERN PORTIONS OF THE FORECAST AREA, GENERALLY SOUTH OF A
HINCKLEY TO PARK FALLS LINE AND THEN SLIDE EASTWARD THROUGH
SATURDAY MORNING. IT'S DOUBTFUL THE PRECIPITATION WILL PUSH
FARTHER NORTH THAN A WALKER TO TWO HARBORS LINE.
ANOTHER ROUND OF PRECIPITATION IS POSSIBLE SATURDAY NIGHT AND
SUNDAY AS ANOTHER WEAK LLJ DEVELOPS OVER CENTRAL MINNESOTA AND
WEST-CENTRAL WISCONSIN. LOWERED POPS ACROSS THE IRON RANGE AND
THE BORDERLANDS TO REFLECT THE FORCING STAYING WELL TO THE SOUTH
OF THOSE AREAS.
REMAINDER OF THE FORECAST IS UNCHANGED.
PREV UPDATE...ISSUED AT 339 PM CDT FRI JUN 13 2025
ISSUED A FROST ADVISORY FOR COOK AND NORTHERN LAKE COUNTIES FOR
TONIGHT INTO SATURDAY MORNING WITH GOOD RADIATIONAL COOLING
EXPECTED. WILL MONITOR TRENDS THROUGH THE EVENING SHOULD THE

AND KOOCHICHING COUNTIES.
DISCUSSION
ISSUED AT 123 PM CDT FRI JUN 13 2025
AFTER A BRIEF LULL IN RAIN SHOWER ACTIVITY FROM THE BRAINERD
LAKES AREA EAST INTO NORTHWEST WISCONSIN LATE THIS AFTERNOON AND
EVENING, RAIN SHOWERS ARE EXPECTED TO INCREASE IN COVERAGE ONCE
AGAIN FOR THESE AREAS ALONG THE LOW LEVEL BAROCLINIC ZONE LATE
TONIGHT AND CONTINUE INTO SATURDAY. OVERALL, IT WILL BE A COOL
MID JUNE DAY ACROSS THE NORTHLAND ON SATURDAY WITH EASTERLY FLOW
BETWEEN SURFACE HIGH PRESSURE OVER LAKE SUPERIOR AND LOW
PRESSURE ACROSS THE PLAINS. IN FACT, DOWNWIND AREAS FROM LAKE
SUPERIOR WILL LIKELY ONLY WARM INTO THE 50S, WITH RATHER BREEZY
NORTHEAST WINDS ESPECIALLY FOR THE TWIN PORTS WITH NORTHEAST
WINDS FUNNELING TOWARDS THE HEAD OF THE LAKE. STRATUS AND SOME
FOG IN THE HIGHER ELEVATIONS OF THE TWIN PORTS ALSO SEEMS LIKELY
FOR THIS SETUP LATE TONIGHT AND SATURDAY.
LOOKING AHEAD TO NEXT WEEK, MORE OF A SUMMER TIME PATTERN
SETUPS WITH LOW AMPLITUDE UPPER LEVEL RIDGING SUNDAY, BREAKING
DOWN TO MORE ZONAL FLOW AS A SERIES OF SHORTWAVES PROPAGATE INTO
THE CENTRAL US MONDAY THROUGH WEDNESDAY, WITH A LIKELY BUILDING
UPPER LEVEL RIDGE LATE NEXT WEEK. THE MID LEVEL JET ALONG THE
CREST OF THE CENTRAL US RIDGE IS ALSO EXPECTED TO STRENGTHEN
SOME LATE NEXT WEEK, WHICH POINTS TO A POSSIBLE RING OF FIRE
SETUP FOR CONVECTION LATE NEXT WEEK ACROSS THE NORTHERN PORTIONS
OF THE MIDWEST ALONG THE NORTHERN PERIPHERY OF THE INCREASING
MOISTURE AND BUOYANCY AND RELATIVELY LOWER CAPPING, WITH BETTER
SHEAR WITH THE MID LEVEL JET. AI AND ML SEVERE PROBABILISTIC
GUIDANCE ALL SHOW MULTIPLE CHANCES FOR SEVERE WEATHER ACROSS THE
UPPER MIDWEST NEXT WEEK. THE SEVERE POTENTIAL FOR NORTHWEST
WISCONSIN AND NORTHEAST MINNESOTA NEXT WEEK WILL BE TIED TO HOW
QUICKLY AND HOW FAR NORTH THE GREATER MOISTURE AND BUOYANCY
BUILD THROUGH THE WEEK, AND THE TIMING OF LOWER PREDICTABILITY
WAVES AS BACKGROUND FORCING. OVERALL, IT WILL BE WARMER WITH
WIDESPREAD HIGHS IN THE 70S AND LOWER 80S, WITH INCREASING
HUMIDITY AND THUNDERSTORM AND SEVERE THUNDERSTORM POTENTIAL THAT
MATCH EXPECTATIONS FOR MID TO LATE JUNE IN THE NORTHLAND.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1254 AM CDT SAT JUN 14 2025
RAIN IS EXPECTED THROUGH THE MORNING AT HYR. WHILE VISIBILITY
MAY REMAIN VFR PREDOMINANTLY, MVFR VISIBILITY IS EXPECTED AT
LEAST FOR BRIEF PERIODS TONIGHT AS HEAVIER BURSTS OF RAIN PASS
OVER. CEILINGS ARE EXPECTED TO REMAIN IFR PREDOMINANTLY THROUGH
THE PERIOD THERE. AT BRD, SHOWER CHANCES ARE COMPARATIVELY LESS
(~50% CHANCE), SO VISIBILITY IS EXPECTED TO REMAIN VFR, THOUGH
THE IFR CEILINGS ARE EXPECTED TO MOVE IN THERE AS WELL. SHOWERS
MAY JUST GRAZE DLH LATER TONIGHT WITH CEILINGS GRADUALLY FALLING
FROM VFR TO MVFR/IFR TOWARDS SUNRISE AND REMAINING THERE THROUGH
EARLY AFTERNOON. THERE IS A POSSIBILITY THAT SKIES COULD SCATTER
ENOUGH THERE FOR SOME BRIEF VFR CONDITIONS IN THE AFTERNOON.
SOME FOG MAY BE POSSIBLE AFTER SUNSET. CONDITIONS ARE EXPECTED
TO REMAIN PREDOMINANTLY VFR AT HIB/INL AS MOISTURE AND RAIN
STAYS SOUTH. WINDS AT ALL TERMINALS WILL GENERALLY REMAIN STEADY
FROM THE EAST WITH SLIGHT VARIATIONS. BREEZY AT DLH WITH GUSTS
15-20 KT THROUGH THE PERIOD AND A BIT LIGHTER ELSEWHERE.

NORTHEAST WINDS WITH GUSTS TO 25 KTS AND WAVES OF 3 TO 6 FEET
WILL CONTINUE FROM TWO HARBORS THROUGH DULUTH AND PORT WING
THROUGH SATURDAY MORNING, AND A SMALL CRAFT ADVISORY IS IN
EFFECT UNTIL 1 PM CDT SATURDAY. THIS MAY NEED TO BE EXPANDED
FURTHER INTO THE AFTERNOON SATURDAY FOR WAVES FROM THE
PROLONGED NORTHEAST WIND EVENT. ELSEWHERE, FROM TACONITE HARBOR
TO TWO HARBORS, AND MOST OF THE SOUTH SHORE, A SMALL CRAFT
ADVISORY IS IN EFFECT UNTIL 5 AM SATURDAY MORNING FOR WAVES OF 2
