059 FXUS63 KFGF 260332 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 1032 PM CDT Tue Aug 25 2026 .KEY MESSAGES... - Slightly cooler and drier Wed/Thur before warmer temps and rain chances return for the weekend. && .DISCUSSION... Issued at 239 PM CDT Tue Aug 25 2026 ...Synopsis... Slow moving H5 upper low continues to move to the east and southeast across southern Manitoba this afternoon. Scattered showers and isolated thunderstorms will be possible along the International Border and areas south to about Highway 2. A few stronger storms could form this afternoon in northwest Minnesota. Heading into Wednesday, showers and storms end during the early morning, with dry weather the remainder of the day. Temperatures will be very similar each day through the weekend, with widespread 70s to low 80s for high temps each afternoon. Our next chance for precipitation will be late Friday through the weekend as another H5 shortwave moves slowly across the Northern Plains. ...Isolated Severe Thunderstorms This Evening... Showers and thunderstorms are moving across northwest Minnesota this afternoon, most being very light. This is in response to an upper low and H5 trough extending into northwest Minnesota, in the presence of modest instability and peak daytime heating. At this time, the best forcing remains east of the area; however, there is just enough forcing, along small lobes of higher vorticity that are moving along the flow to the south of the main H5 low, to allow a mention of isolated strong to severe storms this afternoon. Best chances will extend southward along and east of a line from Lake of the Woods to about Wadena, MN. The primary concern will be hail up to 1 inch in diameter, with a lower chance for damaging wind gusts up to 60 mph. && .AVIATION /04Z TAFS THROUGH 06Z THURSDAY/... Issued at 1032 PM CDT Tue Aug 25 2026 Skies are currently VFR at all sites but MVFR to IFR stratus is expected to develop overnight at BJI and TVF after midnight and last through the sunrise hours beginning to lift after 9am with skies quickly clearing by noon. Winds remaining NW today with 10-15kts winds gusting 20-25kts. Some lingering showers yet this evening and into the early Wednesday morning hours but limited impacts to operations from these. Overall the overnight stratus is the main hazard to operations. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && $$ DISCUSSION...Lynch AVIATION...TT
