DISCUSSION
ISSUED AT 1144 AM CDT MON JUL 27 2026
FOR THE REST OF TODAY, A HOT AND MUGGY AFTERNOON ACROSS THE
NORTHLAND WITH TEMPERATURES WARMING WELL INTO THE 80S AND EVEN
LOW 90S FAR INLAND. CLOSER TO LAKE SUPERIOR, BRISK NORTHEAST
WINDS WILL KEEP TEMPERATURES COOLER BUT WILL ALSO DRIVE HIGH
WAVES AND DANGEROUS RIP CURRENTS ALONG THE TWIN PORTS BEACHES -
A BEACH HAZARDS STATEMENT IS IN EFFECT TODAY. AREAS OF DENSE FOG
AND WILL ALSO LINGER INTO THE AFTERNOON, ESPECIALLY NEAR THE
LAKE.
HEADING INTO TONIGHT AND TUESDAY, HIGH PRESSURE BEGINS TO BUILD
INTO OUR AREA, USHERING IN A DRIER AND A SLIGHTLY MORE
COMFORTABLE AIRMASS. WHILE DAYTIME HIGHS ON TUESDAY WILL REMAIN
UNSEASONABLY WARM IN THE 80S TO LOWER 90S, THE OPPRESSIVE
HUMIDITY WILL TAKE A SUBTLE BREAK. EXPECT MOSTLY SUNNY SKIES
WITH PATCHY SMOKE CONTINUING TO DRIFT OVERHEAD. A STRAY
AFTERNOON SHOWER OR THUNDERSTORM CANNOT BE COMPLETELY RULED OUT,
BUT THE VAST MAJORITY OF THE REGION WILL STAY DRY AND PLEASANT.
MARINE FOG MAY DRIFT ON AND OFF SHORE BUT THAT WILL ALSO HELP
MODERATE TEMPERATURES.
THE QUIET WEATHER HOLDS FIRM THROUGH WEDNESDAY AS THE UPPER
LEVEL RIDGE DOMINATES THE CENTRAL UNITED STATES. HIGHS WILL
AGAIN REACH THE MID 80S TO LOWER 90S ACROSS NORTHEAST MINNESOTA
AND NORTHWEST WISCONSIN. OVERNIGHT LOWS DURING THIS STRETCH WILL
PROVIDE SOME RELIEF, DROPPING COMFORTABLY INTO THE UPPER 50S
AND 60S.
OUR NEXT SIGNIFICANT WEATHER MAKER ARRIVES ON THURSDAY AND
FRIDAY AS A SHORTWAVE TROUGH AND ASSOCIATED COLD FRONT
APPROACH FROM THE WEST. THIS SYSTEM WILL BRING OUR NEXT
WIDESPREAD CHANCE FOR SHOWERS AND THUNDERSTORMS, AND POSSIBLY
SOME SEVERE THREAT TOO THOUGH SHEAR LOOKS A LITTLE WEAK AT THE
MOMENT AND COULD BE THE LIMITING FACTOR. AS SOUTHERLY FLOW
INCREASES AHEAD OF THE FRONT, HUMIDITY LEVELS WILL CREEP BACK
UP, MAINTAINING HIGH TEMPERATURES IN THE UPPER 80S DESPITE THE
INCREASED CLOUD COVER AND PRECIPITATION CHANCES.
LOOKING AHEAD TO THE UPCOMING WEEKEND, THE NORTHLAND WILL REMAIN
IN A SOMEWHAT STAGNANT WEATHER PATTERN. AFTERNOON HIGHS WILL
GENERALLY STAY IN THE 80S. WITH THE MAIN STORM TRACK POSITIONED
TO OUR NORTH, WE CAN EXPECT OCCASIONAL, LESS ORGANIZED WAVES OF
SHOWERS AND STORMS TO DIVE ACROSS THE AREA.
LOOKING TOWARD THE FIRST WEEK OF AUGUST, THE CLIMATE PREDICTION
CENTER INDICATES THAT THE UPPER MIDWEST AND GREAT LAKES REGION
WILL LIKELY EXPERIENCE ABOVE NORMAL TEMPERATURES. PRECIPITATION
SIGNALS ARE WEAKER, BUT SLIGHTLY FAVOR NEAR TO BELOW NORMAL
PRECIPITATION ACROSS THE AREA AS UPPER LEVEL RIDGING INFLUENCES
THE CENTRAL CONUS.
AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
ISSUED AT 1223 AM CDT TUE JUL 28 2026
SURFACE HIGH PRESSURE IS STALLED OVER LAKE SUPERIOR THROUGH THE
FORECAST PERIOD WITH NORTHEASTERLY FLOW OFF THE LAKE SENDING FOG
INLAND. DLH/HIB WILL SEE REDUCED VISIBILITIES THROUGH THE
MORNING HOURS AND POSSIBLY HYR. THIS FOG WILL ERODE AFTER
SUNRISE WITH VFR CONDITIONS EXPECTED THROUGH THE REMAINDER OF
THE DAY. A STRAY SHOWER OR SPRINKLE CAN'T BE RULED OUT DURING
THE AFTERNOON BUT COVERAGE IS EXPECTED TO BE VERY MINIMAL.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 1138 AM CDT MON JUL 27 2026
HAZARDOUS CONDITIONS WILL PERSIST ACROSS WESTERN LAKE SUPERIOR
INTO THIS AFTERNOON AND PROBABLY OVERNIGHT. DENSE FOG WILL
RESTRICT VISIBILITY TO UNDER ONE NAUTICAL MILE FOR NEARSHORE
WATERS, WHILE NORTHEAST WINDS GUSTING TO 25 KNOTS BUILD WAVES OF
3 TO 5 FEET. SMALL CRAFT ADVISORIES AND A DENSE FOG ADVISORY
REMAIN IN EFFECT TODAY. WINDS AND WAVES WILL SUBSIDE THIS
EVENING AS HIGH PRESSURE BUILDS IN, ALLOWING WINDS TO BECOME
LIGHT AND VARIABLE AT 10 KNOTS OR LESS FOR TUESDAY AND
WEDNESDAY. DENSE FOG MAY LINGER OVERNIGHT THOUGH.
FOR THE OPEN WATER DISCUSSION, REFER TO THE NWS MARQUETTE AREA
FORECAST DISCUSSION AT WEATHER.GOV/MQT.
