UPDATE
ISSUED AT 327 AM CDT THU OCT 15 2026
CHANGE IN THE FORECAST FOR TODAY WAS TO CHANGE START AND END
TIME OF THE WIND ADVISORY. BASED ON HRRR FORECASTS OF PEAK WINDS
THERE ARE TWO CORRIDORS. ONE IS MORE WITH A WEST-NORTHWEST WIND
SHIFT SOUTHWEST OF THE SFC LOW ORIGINATING IN THE SASKATOON AND
REGINA AREA MOVING SOUTHEAST THRU WESTERN INTO CENTRAL ND INTO
NORTH CENTRAL SD. THIS IS MORE DAYTIME TODAY...WITH CHANCES FOR
WINDS REACHING ADVISORY AFTER 18Z IN FAR WESTERN FCST AREA CANDO
TO DEVILS LAKE TO VALLEY CITY. THOUGH IT IS POSSIBLE ADVISORY
LEVEL WINDS REMAIN A BIT WEST OF THIS AREA. ANOTHER CORRIDOR OF
HIGH WIND POTENTIAL WILL BE FELT DIRECTLY TO THE WEST OF THE SFC
LOW IN ASSOCIATED WITH COLD ADVECTION THAT DROPS SOUTH FROM
WINNIPEG TO FARGO AFTER DARK TONIGHT. BUFKIT SOUNDINGS FOR FARGO
AND GRAND FORKS SHOW BEST LAPSE RATES TO MIX DOWN WINDS FROM 870
MB TO BE FELT 04Z-08Z FRIDAY WHERE WINDS OF 40-45 KTS SHOULD
MIX DOWN. WIND DIRECTION DURING THIS TIME OVERNIGHT IS NORTHERLY
AND FAVORABLE FOR A PERIOD OF HIGHEST WINDS IN THE VALLEY. PUSH
OF COLD AIR ISNT INTENSE SO DONT EXPECT AN OVER ACHIEVING WIND
EVENT AT THIS TIME, AS WE MAY GET IN THE WINTER TIME IN A
SIMILAR SITUATION. WITH THE TIMING ABOVE...WENT ADVISORY 18Z TO
09Z FOR DVL REGION, KEPT IT EARLY YET IN CASE WINDS INCREASE
FAST ENOUGH. IN THE VALLEY WHERE INITIAL WINDS WILL NOT BE

..SYNOPSIS
WIDESPREAD STRATUS DECK CONTINUES TO LINGER ACROSS THE NORTHERN
PLAINS AND UPPER MIDWEST THIS AFTERNOON, KEEPING TEMPERATURES IN THE
LOW TO MID 40S THUS FAR TODAY. UPPER FLOW IS NEARLY ZONAL, BUT WILL
BE TRANSITIONING TO SOUTHWEST THIS EVENING AND OVERNIGHT BEFORE
SHIFTING TO THE NORTHWEST LATE THURSDAY EVENING. VERY LIGHT
PRECIPITATION IS POSSIBLE ALONG A COLD FRONT THURSDAY AFTERNOON AND
EVENING, MAINLY FROM THE RED RIVER VALLEY EASTWARD INTO NORTHWEST
MINNESOTA. BREEZY NORTHWEST WINDS PICK UP EARLY THURSDAY MORNING AND
PERSIST THROUGH MUCH OF THE DAY. THE STRONGEST PRESSURE GRADIENTS
SHIFT EASTWARD OVERNIGHT INTO FRIDAY MORNING WITH WEAK, TRANSIENT,
RIDGING BRINGING WARMER TEMPERATURES INTO THE AREA FOR SATURDAY AND
SUNDAY.
..BREEZY NORTHWEST WINDS THURSDAY
SUSTAINED NORTHWEST WINDS OF 20-30 MPH ARE POSSIBLE THURSDAY WITH
GUSTS UPWARDS OF 40-45 MPH. THIS WILL BE IN RESPONSE TO A FAST
MOVING COLD FRONT AND STRONG PRESSURE RISES ON THE WESTERN SIDE OF
THE FRONTAL PASSAGE. THERE IS STILL SOME UNCERTAINTY SURROUNDING
CLOUD COVER, WHICH COULD LIMIT MIXING DURING THE AFTERNOON AND
EVENING AND SLIGHTLY REDUCE THE POTENTIAL MAX WIND GUSTS. AT THIS
TIME, THE SIGNAL IS CONSISTENTLY STRONG, HOWEVER, WITH GENERALLY
MODERATE TO HIGH CONFIDENCE IN THE POSSIBILITY OF ADVISORY
LEVEL WINDS.
..FREEZING TEMPERATURES POSSIBLE FRIDAY NIGHT
GUIDANCE CONTINUES TO BRING COLDER AIR INTO THE AREA FOLLOWING
THURSDAY'S COLD FRONT. LOW TEMPERATURES FRIDAY MORNING ARE EXPECTED
TO BE IN THE LOWER 30S, BUT WITH LINGERING CLOUD COVER. A BETTER
CHANCE OF UPPER 20S AND LOW 30S WILL BE FRIDAY NIGHT INTO SATURDAY
MORNING AS CLOUD COVER IS EXPECTED TO DIMINISH BY MIDDAY FRIDAY.
AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
ISSUED AT 1130 PM CDT WED OCT 14 2026
SATELLITE AND SURFACE OBSERVATION TRENDS SHOW VFR CONDITIONS
ARE SLOWLY ARRIVING OVER EASTERN ND. MVFR CEILINGS APPEAR
LIKELY TO LINGER INTO THE EARLY OVERNIGHT OVER PARTS OF
NORTHEAST ND AND NORTHWEST MN BEFORE FINALLY CLEARING DUE TO THE
SHIFTING SURFACE PATTERN AND INCREASING SOUTHERLY FLOW (8-10Z).
AFTER A PERIOD OF VFR CONDITIONS MIDDAY THURSDAY A COLD FRONT
MOVES INTO NORTHEAST ND AND FAR NORTHWEST MN RETURNING MVFR
CEILINGS ACROSS EASTERN ND AND NORTHWEST MN DURING THE AFTERNOON
AND EVENING (LOWER CHANCE FOR PREVAILING IFR). SCATTERED LIGHT
RAIN SHOWERS ARE MOVING ACROSS SOUTHEAST ND INTO WEST CENTRAL MN
EARLY IN THE TAF PERIOD, HOWEVER MOST LOCATIONS SHOULD REMAIN
DRY (KFAR HAS BEST CHANCE FOR LIGHT RAIN). A MORE ORGANIZED
PERIOD OF LIGHT RAIN MOVES THROUGH NORTHWEST MN BEHIND THE COLD
FRONT THURSDAY EVENING.
WINDS ARE CURRENTLY LIGHT, BUT WITH THE APPROACH OF LOW
PRESSURE THEY SHOULD SHIFT TO THE SOUTH AND SOUTHWEST OVERNIGHT
INCREASING BY THE MORNING HOURS. BEHIND THE COLD FRONT WINDS
WILL TURN TO THE WEST-NORTHWEST AND INCREASE. GUSTS 30KT OR
HIGHER ARE LIKELY OVER PARTS OF EASTERN ND THURSDAY AFTERNOON,
WITH THE HIGHEST GUSTS ALONG AND WEST OF THE RED RIVER VALLEY
DURING THE EVENING/OVERNIGHT PERIOD THURSDAY.
