UPDATE
ISSUED AT 111 AM CDT WED AUG 5 2026
DRY, COOLER CONDITIONS CONTINUE TODAY, WITH MUCH OF NORTHEAST
MINNESOTA IN THE 40S AND THE REST OF THE NORTHLAND TO JOIN IN
THE EARLY MORNING HOURS. TODAY WILL BE DRIEST, AND LOWERED RH
FURTHER THAN MOST GUIDANCE DUE TO EXPECTED MIXING DOWN OF DRY
AIR.
DISCUSSION
ISSUED AT 139 PM CDT TUE AUG 4 2026
NORTHWESTERLY FLOW IS BRINGING A CLASSIC AUGUST FALL TEASER TODAY,
WITH BREEZY WINDS, A BROKEN ALTOCUMULUS CLOUD DECK, AND DEWPOINTS IN
THE 50S. EVEN LOWER DEWPOINTS IN THE 40S ARE EXPECTED OVERNIGHT INTO
WEDNESDAY MORNING, WHICH WILL LIKELY MAKE FOR A RELATIVELY CHILLY
NIGHT TONIGHT. EXPECT OVERNIGHT LOWS IN THE 40S FOR MOST, EXCEPT
RIGHT ALONG LAKE SUPERIOR.
RINSE AND REPEAT TOMORROW WITH A WESTERLY BREEZE IN THE AFTERNOON,
LOWER DEWPOINTS, AND HIGH TEMPERATURES IN THE 70S.
A LITTLE WIGGLE IN THE UPPER LEVEL FLOW THURSDAY SHOULD ALLOW FOR
SOME MOISTURE AND WARMTH ADVECTION BACK INTO THE AREA, WITH
DEWPOINTS IN THE MID TO UPPER 50S AND TEMPERATURES RISING INTO THE
80S. THAT IMPULSE COULD ALSO LEAD TO SOME SCATTERED SHOWERS AND
THUNDERSTORMS LATE THURSDAY THROUGH FRIDAY.
WE EXPECT TO STAY UNDER BROAD UPPER LEVEL TROUGHING INTO NEXT WEEK
WHICH WILL KEEP US ON THE SLIGHTLY COOLER SIDE. ANY UPPER LEVEL
SHORTWAVES THAT MOVE THROUGH COULD BRING SOME PASSING PRECIPITATION
CHANCES.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 614 AM CDT WED AUG 5 2026
VFR CONDITIONS FOR ALL TERMINALS FOR THE TAF PERIOD. FOG AT HIB
AND HYR ARE EXPECTED TO LIFT IN THE NEXT COUPLE HOURS, THOUGH
THERE MAY BE A FEW OCCASIONAL DIPS YET AT HYR. DIURNAL CUMULUS
IS EXPECTED AGAIN THIS AFTERNOON WITH CLOUD BASES AROUND 7 KFT,
AND WINDS WILL BE OUT OF THE WEST TO SOUTHWEST UP TO 15 KTS.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 111 AM CDT WED AUG 5 2026
SOUTHWESTERLY FLOW WILL CONTINUE OVER THE NEXT COUPLE DAYS.
WINDS UP TO 15 KTS ARE EXPECTED TODAY. THERE IS A BETTER CHANCE
TOMORROW FOR WIND GUSTS UP TO 25 KTS IN THE NEAR SHORE WATERS
WHICH WILL POSE A THREAT TO SMALL CRAFT. A SMALL CRAFT ADVISORY
WILL LIKELY BE NEEDED THURSDAY AFTERNOON INTO THE EARLY EVENING.
FOR THE OPEN WATER DISCUSSION, REFER TO THE NWS MARQUETTE AREA
FORECAST DISCUSSION AT WEATHER.GOV/MQT.
FIRE WEATHER
ISSUED AT 111 AM CDT WED AUG 5 2026
MINIMUM RH HAS LOWERED FOR TODAY, WITH VALUES RANGING 29 TO 35
PERCENT THIS AFTERNOON. WINDS, HOWEVER, SHOULD REMAIN AROUND 15
MPH OR LESS OUT OF THE WEST TO SOUTHWEST, SO CRITICAL FIRE
WEATHER CONDITIONS ARE EXPECTED TODAY. TOMORROW WILL HAVE
SLIGHTLY HIGHER MINIMUM RH VALUES, BUT HIGHER WINDS AS WELL OUT
OF THE SOUTHWEST UP TO 20 MPH. RHS INCREASE EVEN FURTHER LATER
THIS WEEK WITH RISING DEWPOINTS AND THE RETURN OF CHANCES FOR
PRECIPITATION RETURN.

BREAKDOWN OF FIRE WEATHER CONDITIONS.
