909 FXUS63 KMPX 242328 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 628 PM CDT Thu Sep 24 2026 .KEY MESSAGES... - Scattered rain chances return this weekend with Saturday offering the best chance for showers across much of Minnesota and western Wisconsin. - A frontal passage brings more widespread rain Monday night into Tuesday with locally heavier rainfall possible. && .DISCUSSION... Issued at 137 PM CDT Thu Sep 24 2026 Light rain continues to spread eastwards into western Wisconsin, but should begin to diminish as we get later into the afternoon. Rainfall amounts will be on the order of a tenth of an inch or less. Skies remain mostly cloudy into Friday which will keep temperatures fairly steady, falling to around 60 overnight & warming back into the upper 60s tomorrow afternoon. Rain chances return this weekend as a weak disturbance moves through the Upper Midwest. Saturday currently looks like the wetter day, with scattered showers & a few thunderstorms developing across much of Minnesota & western Wisconsin. Similar to today, showers will be more widespread across western Minnesota compared to eastern Minnesota & western Wisconsin. Expected rainfall amounts this weekend range from around half an inch across western Minnesota to only a tenth or less across western Wisconsin. A stronger shortwave & surface front approaches the region Monday. Southerly winds ahead of this system should allow temperatures to moderate somewhat, with highs climbing back into the upper 60s to around 70 in many areas. Increasing moisture will also set the stage for a more widespread round of rain as a cold front moves through Monday night into Tuesday. This currently looks like the best chance for a broad, soaking rain during the next several days, with current guidance supporting a widespread 0.50-1" of rain and locally higher amounts possible. Severe weather still appears unlikely, but embedded thunderstorms could enhance rainfall rates in spots. Cooler air filters back into the region behind the front Tuesday into Wednesday, with more fall-like temperatures through the rest of the week with highs in the low to mid 60s & lows in the 40s. The pattern may remain active as another disturbance develops along or north of the stalled frontal zone late Wednesday into Thursday. Some spread in the guidance exists on just how far north the precipitation for this system may extend into Minnesota, but at least the far southern portion of the state appears positioned for another round of appreciable rainfall. Otherwise, high pressure building over the Upper Midwest should keep us cool & dry through next weekend. && .AVIATION /00Z TAFS THROUGH 06Z FRIDAY/... Issued at 628 PM CDT Thu Sep 24 2026 Patches of light rain and drizzle continue at TAF issuance time, but it should taper off during the next several hours. IFR/LIFR conditions across western MN will prevail through mid to late Friday morning. Areas east of MKT and MSP will remain mostly VFR through the period with dry low level southeast flow maintaining much higher cloud bases. KMSP...Improved the TAF significantly with prospects of lower cloud development now appearing unlikely. There may be a brief period of MVFR cigs Friday as diurnal clouds begin forming, but bases should rise back to VFR levels by afternoon. /OUTLOOK FOR KMSP/ SAT...Chc MVFR/-SHRA. Wind SE 10-15 kts.
