UPDATE
ISSUED AT 141 AM CDT WED AUG 26 2026
CURRENT CONDITIONS AND TODAY:
DURING THE EARLY MORNING HOURS, LINGERING LIGHT SHOWERS WILL
CONTINUE ACROSS THE NORTHLAND FOLLOWING THE EVENING COLD FRONTAL
PASSAGE. AS WE MOVE INTO THE DAYLIGHT HOURS TODAY, BREEZY
NORTHWEST WINDS WILL SET IN, WITH SUSTAINED WINDS OF 5 TO 15 MPH
WITH GUSTS OF 15 TO 25 MPH. THE HIGHER TERRAIN OF THE NORTH
SHORE WILL HAVE THE STRONGEST WINDS DURING THE MORNING AND EARLY
AFTERNOON HOURS. TEMPERATURES WILL BE COOLER AGAIN TODAY, WITH
HIGHS ONLY IN THE 70S FOR MOST LOCATIONS. DOWNSLOPING WITH THESE
NORTHWEST WINDS MAY ACTUALLY HELP KEEP THE IMMEDIATE NORTH
SHORE LOCATIONS A BIT WARMER. THE CYCLONIC FLOW ACROSS THE
REGION AND LINGERING MOISTURE WILL HELP GENERATE SOME SCATTERED
SHOWERS AND A FEW NON-SEVERE THUNDERSTORMS TODAY, WITH STORMS
MOST LIKELY DURING THE AFTERNOON HOURS. THIS ACTIVITY WILL
RAPIDLY TAPER OFF AROUND SUNSET AS DRIER AIR WORKS INTO THE
REGION. SKIES WILL GRADUALLY CLEAR FOR TONIGHT, SETTING THE
STAGE FOR A COOLER NIGHT TONIGHT WITH LOWS DIPPING INTO THE
UPPER 40S AND 50S.
THURSDAY AND FRIDAY:
WE CAN EXPECT BEAUTIFUL LATE SUMMER WEATHER ACROSS OUR AREA
BOTH DAYS. EXPECT PLENTY OF SUNSHINE AND DRY CONDITIONS BOTH
DAYS WITH AFTERNOON HIGHS SITTING COMFORTABLY IN THE UPPER 60S
AND 70S. WINDS WILL BE LIGHTER ON THURSDAY AND BECOME LIGHT AND
VARIABLE FOR FRIDAY AS A HIGH PRESSURE SYSTEM SLOWLY SLIDES
ACROSS THE AREA.
DISCUSSION
ISSUED AT 1217 PM CDT TUE AUG 25 2026
A WARM FRONT IS MOVING THROUGH THE REGION MID-DAY TODAY,
BRINGING A FEW SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS TO
THE TIP OF THE ARROWHEAD AND ENTERING NORTH-CENTRAL WISCONSIN.
THESE STORMS ARE PART OF WHAT IS ROUND 1 AND ARE NOT EXPECTED
TO BE SEVERE. BEHIND THE WARM FRONT, ATMOSPHERIC RECOVERY WILL
OCCUR THIS AFTERNOON AND LAST INTO THE EARLY EVENING HOURS
WITHIN THE SHORT-LIVED WARM SECTOR OF A LOW PRESSURE SYSTEM
CENTERED OVER MANITOBA, MINNESOTA, AND ONTARIO. AS DAYTIME
HEATING MAXIMIZES INSTABILITY, ISOLATED SEVERE THUNDERSTORMS ARE
POSSIBLE BEGINNING FIRST IN THE FAR NORTHERN MINNESOTA
BORDERLANDS LATE THIS AFTERNOON, WITH AN ONSET TIME AROUND 3 TO
4 PM.
THE HAZARD THREATS OF LARGE HAIL AND DAMAGING WIND GUSTS WILL
BUILD SOUTHEASTWARD EARLY THIS EVENING TOWARDS THE TWIN PORTS.
BY LATER THIS EVENING, CLOSER TO SUNSET, THE SEVERE THREAT MOVES
INTO INTO NORTHWEST WISCONSIN AND THE EASTERN ARROWHEAD. SEVERE
STORM CHANCES ARE EXPECTED TO TAPER SHORTLY AFTER SUNSET THIS
EVENING WITH A COLD FRONTAL PASSAGE OCCURRING TONIGHT. BEHIND
THE FRONT, LINGERING COLD AIR ADVECTION SHOWERS WILL CONTINUE
THROUGH THE OVERNIGHT HOURS, BUT THESE WILL ONLY BRING VERY
LOCALIZED AND LIGHT RAINFALL TO THE NORTHLAND.
FOR WEDNESDAY, A SLIGHT COOL DOWN IS FORECAST AND BREEZIER
POST- FRONTAL REGIME TAKES HOLD ACROSS THE AREA. EXPECT GUSTY
NORTHWEST WINDS SUSTAINED AROUND 10 TO 15 MPH WITH GUSTS
REACHING 20 TO 30 MPH. THE EXCEPTION FOR THE COOL DOWN WILL BE
THE NORTH SHORE WITH THOSE NORTHWEST WINDS DOWNSLOPING AND
AIDING IN WARMER TEMPERATURES FOR THE IMMEDIATE COASTAL AREAS.
THE LIGHT AND LOCALIZED RAIN SHOWERS FROM THE OVERNIGHT HOURS
WILL LAST INTO THE WEDNESDAY DAYTIME PERIOD, ACTUALLY INCREASING
IN COVERAGE UNDER DAYTIME HEATING AND INSTABILITY. A FEW
GENERAL THUNDERSTORMS ARE FORECAST WEDNESDAY AFTERNOON WITHIN
THIS REGIME OF NUMEROUS LIGHT AND VERY LOCALIZED RAIN SHOWERS.
SEVERE WEATHER IS NOT ANTICIPATED ON WEDNESDAY.
MINIMAL WEATHER CONCERNS ARE EXPECTED FOR THURSDAY AND FRIDAY AS
PASSING HIGH PRESSURE BRINGS A RETURN TO QUIET AND DRY CONDITIONS
ACROSS THE REGION. IT WILL FEEL FAIRLY DRY EACH AFTERNOON WITH
MINIMUM RELATIVE HUMIDITY DROPPING TO 35 TO 45 PERCENT
RANGE...WINDS GENERALLY REMAIN AROUND OR LESS THAN 15 MPH THOUGH
SO NO FIRE WEATHER CONDITIONS ARE FORECAST.
LOOKING AHEAD TO THE WEEKEND, WARM AIR ADVECTION SETS UP AGAIN FRIDAY
NIGHT INTO SATURDAY MORNING AS A WEAK PASSING FRONT AND A LOW TO
MID-LEVEL RIDGE AXIS SLIDES EASTWARD INTO THE NORTHERN PLAINS. THIS
COULD BE A TIME OF A FEW SCATTERED THUNDERSTORMS LATE FRIDAY NIGHT
INTO SATURDAY MORNING. FURTHERMORE, STRONG THUNDERSTORMS CANNOT BE
RULED OUT LATER SATURDAY OR AT SOME POINT SUNDAY. A LOW PRESSURE
SYSTEM IN FAR NORTHERN ONTARIO AND A REINFORCING FRONTAL PASSAGE
FORECAST FOR SUNDAY WILL KEEP THE PATTERN ACTIVE, AS CONVECTION OVER
THE NORTHERN PLAINS MAY SPILL OVER AND SLOWLY DECAY INTO THE
NORTHLAND. PENDING ANY INCREASES IN SKY COVER OR LINGERING
PRECIPITATION, SUNDAY COULD ACTUALLY BE SOMEWHAT WARM INTO THE
MID-80S FOR LOCATIONS SOUTH OF US HWY 2. GENERALLY MINIMAL
WEATHER CONCERNS TO START NEXT WEEK UNDER SEASONABLE
TEMPERATURES AND MAINLY DRY CONDITIONS LIKELY.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

PERHAPS IFR STRATUS IS ALSO EXPECTED TO SPREAD INTO THE AREA
FROM THE NORTHWEST, BRINGING ISOLATED, OFF-AND-ON LIGHT RAIN
SHOWERS. DURING THE MORNING HOURS WEDNESDAY, WE EXPECT THOSE
LOWER CEILINGS TO SLOWLY RISE TO AT LEAST MVFR, EVEN AS
SCATTERED SHOWERS DEVELOP OVER MAINLY THE ARROWHEAD AND
NORTHWEST WI, MAINLY AFFECTING KINL, KHIB, KDLH AND KHYR. HAVE
HANDLED WITH VCSH GROUPS FOR NOW, BUT THERE MAY BE BRIEF PERIODS
OF MVFR CEILINGS WITH STRONGER SHOWERS. NORTHWEST WINDS WILL
ALSO INCREASE AND BECOME GUSTY, UP TO 20KTS FOR SEVERAL HOURS.
