DISCUSSION
ISSUED AT 217 PM CDT FRI OCT 23 2026
FOG LINGERS IN AREAS NEAR LAKE SUPERIOR THIS AFTERNOON. DENSE
THIS FOG IS EXPECTED TO CLEAR AS A WARM FRONT MAKES ITS WAY
NORTHEAST. TEMPERATURES FOR THE REST OF THE DAY WILL PUSH INTO
THE UPPER 60S AND 70S INLAND, THOUGH THE SHORELINE WILL STAY
SLIGHTLY COOLER UNDER THE FOG AND CLOUD COVER. A WARM FRONT WILL
MOVE THROUGH TODAY, SHIFTING WINDS TO THE SOUTH TO SOUTHWEST AND
INCREASING GUSTS TO UP TO 30 MPH TONIGHT. RAIN SHOWERS WILL
ALSO FOLLOW THE WARM FRONT IN THE LATE AFTERNOON AND OVERNIGHT
HOURS. MOST WILL SEE RAIN ACCUMULATIONS OF LESS THEN 0.1".
SATURDAY, THE ASSOCIATED LOW PRESSURE SYSTEM TRACKING EAST WILL
ALSO BRING A COLD FRONT WEST TO EAST ACROSS OUR AREA. THIS
BOUNDARY WILL PROVIDE ANOTHER ROUND OF LIGHT RAIN SHOWERS AND
PERHAPS AN ISOLATED RUMBLE OF THUNDER. STRONG SOUTHERLY FLOW
CONTINUES AHEAD OF THE FRONT WILL ALLOW HIGHS TO CLIMB INTO THE
60S AND LOWER 70S ONCE AGAIN, MARKING OUR LAST WARM DAY FOR THE
FORESEEABLE FUTURE. RAIN CHANCES WILL QUICKLY TAPER OFF FROM
WEST TO EAST SATURDAY NIGHT.
A MUCH COOLER AND MORE SEASONABLE AIR MASS SETTLES IN ON SUNDAY
BEHIND THE DEPARTING COLD FRONT. HIGHS WILL ONLY REACH THE 40S
AND 50S UNDER MOSTLY SUNNY SKIES AS SURFACE HIGH PRESSURE BUILDS
IN OVER THE AREA. RHS DIP BACK DOWN INTO THE 25-35% RANGE SUNDAY,
BUT WITH LOWER WINDS, NO FIRE WEATHER CONCERNS ARE ANTICIPATED.
THE COOLER AIR MASS WILL ALLOW SUNDAY NIGHT TEMPERATURES TO
DROP BELOW FREEZING FOR MOST INLAND LOCATIONS.
THE EXTENDED FORECAST FOR MONDAY THROUGH THURSDAY FEATURES A
RETURN TO AN ACTIVE WEATHER PATTERN. AN UPPER LEVEL LOW IS
FORECAST TO MOVE EAST OUT OF THE CENTRAL ROCKIES EARLY NEXT
WEEK, BRINGING WIDESPREAD PRECIPITATION CHANCES TO THE REGION
FROM MONDAY INTO WEDNESDAY. WITH THE COOLER AIR MASS FIRMLY IN
PLACE, SOME SNOW COULD MIX IN ON THE NORTHERN FRINGES OF THE
SYSTEM, THOUGH THIS IS CURRENTLY EXPECTED TO BE MINOR
CONVERSATIONAL SNOW WITH SMALL ACCUMULATIONS, IF ANY. HIGH
TEMPERATURES WILL LARGELY REMAIN IN THE 40S AND 50S THROUGH
THURSDAY WITH OVERNIGHT LOWS NEAR OR BELOW FREEZING.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1236 AM CDT SAT OCT 24 2026
LLWS IS EXPECTED AT ALL TERMINALS TONIGHT AND MOST OF SATURDAY
MORNING WITH WARM AIR ADVECTION ONGOING ALOFT. EXPECT AREAS OF
SHOWERS TONIGHT, BUT NOT EXPECTING MUCH FOR VISIBILITY OR
CEILING RESTRICTIONS WITH THOSE. AT DLH, FOG SHOULD BE LARGELY
IMPROVING, BUT WHEN RAINFALL STOPS, SOME FOG COULD STILL
REDEVELOP WITH UPSLOPE FLOW EXPECTED TONIGHT. INTO SATURDAY,
LLWS WILL GRADUALLY END WITH A COLD FRONT PASSING THROUGH. ALONG
WITH THE COLD FRONT, EXPECT ANOTHER ROUND OF SHOWERS. VISIBILITY
PROBABLY WON'T BE REDUCED BY MUCH, THOUGH BRIEF MVFR CEILINGS
CAN'T BE RULED OUT. THE WEATHER TRENDS QUIETER WITH WINDS
DECREASING AFTER SUNSET AS HIGH PRESSURE APPROACHES FROM THE
WEST.

CLEAR AS A WARM FRONT MAKES ITS WAY NORTHEAST WITH LIGHT RAIN
SHOWERS. NORTHEAST WINDS AROUND 5 TO 10 KNOTS THIS AFTERNOON
WILL FLIP TO THE SOUTH AND INCREASE TONIGHT INTO SATURDAY. WIND
GUSTS TO 25 KNOTS AND BUILDING WAVES WILL LIKELY REQUIRE A SMALL

BRINGING LIGHT RAIN SHOWERS THIS AFTERNOON AND TONIGHT. GUSTY
WINDS UP TO 30 MPH WILL ALSO CONTINUE OVERNIGHT. ADDITIONAL
RAIN ARRIVES ON SATURDAY AS A COLD FRONT CROSSES THE AREA, AND
WINDS WILL DECREASE AS WINDS SHIFT FROM THE SOUTH/SOUTHWEST TO
