DISCUSSION
ISSUED AT 129 PM CDT SUN AUG 9 2026
FOR THE REST OF THE DAY, MAINLY WIDELY SCATTERED RAIN SHOWERS
AND POSSIBLY (10-20% CHANCE ONLY) AN ISOLATED NON-SEVERE
THUNDERSTORM ARE FORECAST THIS AFTERNOON FOR INLAND NORTHWEST
WISCONSIN. THE MAIN HAZARD IF ANY NON-SEVERE STORM COULD COME TO
BE WOULD BE A QUICK BURST OF LOCALIZED HEAVY RAINFALL AND
CLOUD TO GROUND LIGHTNING. MEANWHILE, SMOKE ALOFT DEPARTS
SLOWLY TO THE SOUTHEAST WITH SOME BLUE SKIES RETURNING INTO THIS
AFTERNOON ACROSS THE NORTHLAND. QUIET CONDITIONS TAKE OVER
TONIGHT AS TEMPERATURES DIP SLIGHTLY BELOW NORMAL UNDER LIGHT
WINDS. HOWEVER, THE NEXT ROUND OF SMOKE ALOFT MOVES IN TONIGHT
AND SETS UP FOR MONDAY.
THIS INCOMING SMOKE LAYER WILL BE CREATING SKY COVER FOR AREAS SOUTH
OF US HIGHWAY 2 THROUGHOUT THE DAY ON MONDAY. ASIDE FROM THE HAZY
SKIES, MONDAY WILL FEATURE PLEASANT CONDITIONS WITH NEAR-NORMAL
DAYTIME HIGH TEMPERATURES CLIMBING INTO THE UPPER 70S TO LOWER 80S
ACROSS THE AREA. HUMIDITY LEVELS WILL DROP A BIT, CREATING A
COMFORTABLE FEEL FOR MID-AUGUST. LIGHT VARIABLE WINDS IN THE MORNING
WILL EVENTUALLY TURN TOWARD THE WEST AND NORTHWEST DURING THE
AFTERNOON HOURS.
HEADING INTO THE REST OF THE WEEK, A PERSISTENT NORTHWEST FLOW ALOFT
CONTINUES AS A STALLED FRONTAL BOUNDARY TO OUR SOUTH KEEPS US ON
THE COOLER SIDE. THIS NORTHWEST FLOW CONTINUES TO CREATE NEAR-
NORMAL DAYTIME HIGH TEMPERATURES IN THE 70S TO LOWER 80S, AND
SLIGHTLY BELOW NORMAL LOW TEMPERATURES EACH NIGHT FALLING INTO
THE MID 40S TO LOWER 50S.
WITHIN THIS NORTHWEST FLOW WILL BE WEAK AND SMALL-SCALE
DISTURBANCES HELPING CREATE THE OFF-AND-ON MAINLY RAIN SHOWER
WITH EMBEDDED NON-SEVERE THUNDERSTORM CHANCES EVERY 36 TO 48
HOURS. ANY SHOWERS AND STORMS WOULD LIKELY BE VERY LOCALIZED AND
SHORT-LIVED IN NATURE FROM THIS SETUP OF SHEAR, MOISTURE AND
INSTABILITY-LIMITED ENVIRONMENTAL PROGS IN LONGER-RANGE ENSEMBLE
GUIDANCE.
AVIATION /18Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 1222 PM CDT SUN AUG 9 2026
A DIURNAL CUMULUS FIELD IS BUILDING FIRST IN FAR NORTHERN
MINNESOTA AND IS FORECAST TO MOVE SOUTHWARD THIS AFTERNOON AND
INCREASE IN COVERAGE. EXPECT A FEW RAIN SHOWERS AND POTENTIALLY
AN ISOLATED NON-SEVERE THIS AFTERNOON IN NORTHWEST WISCONSIN.
THERE IS VERY LOW CONFIDENCE ON IMPACTING ANY TERMINALS THOUGH
GIVEN THE WEAKLY FORCED DIURNAL NATURE OF THESE SHOWERS. HAVE
PLACED A VICINITY SHOWERS MENTION IN THE HAYWARD TAF THOUGH WITH
THIS ISSUANCE. TONIGHT, THERE ARE MEDIUM CONFIDENCE SIGNALS FOR
IFR TO LIFR FOG SO TEMPOS WERE USED TO PLACE EVEN LOWER
CATEGORIES INTO THE HAYWARD AND HIBBING TAFS. LIGHT WINDS THIS
TAF PERIOD.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 121 PM CDT SUN AUG 9 2026
WINDS ACROSS WESTERN LAKE SUPERIOR WILL REMAIN LIGHT FOR THE REST
OF THE DAY AND TONIGHT, GENERALLY OUT OF THE NORTHEAST TO SOUTHWEST
AT 5 TO 10 KNOTS. WAVES WILL REMAIN AT 1 FOOT OR LESS THROUGH
TONIGHT. ON MONDAY, WEST WINDS WILL SHIFT TO THE SOUTHWEST AND
INCREASE TO 10 TO 15 KNOTS, WITH AFTERNOON GUSTS UP TO 25 KNOTS
POSSIBLE, ESPECIALLY NORTH OF TACONITE HARBOR ALONG THE FAR
NORTH SHORE. A SMALL CRAFT ADVISORY MAY BE NEEDED IN TIME FOR
THE GRAND MARAIS TO GRAND PORTAGE ZONE MONDAY AFTERNOON AND
EARLY EVENING. WINDS WILL DIMINISH AGAIN BY MONDAY NIGHT,
BECOMING NORTHWEST AT 5 KNOTS.
