678 FXUS63 KMPX 172356 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 656 PM CDT Fri Oct 17 2025 .KEY MESSAGES... - After today, temperatures will be within 10 degrees of either side of normal the next 7 days. - Breezy conditions through the first half of next week, with the windiest period being Monday night into Tuesday morning, when wind gusts over 40 mph will be possible. && .DISCUSSION... Issued at 252 PM CDT Fri Oct 17 2025 At 2pm, a cold front was just crossing the I-35 corridor. A warm nose at h7 and dry air above that has really limited precip development along it this far north. We have seen some storms develop from northeast KS toward southeast MN, with the CAMS showing this activity zippering its way up the boundary late this afternoon, which may allow a brief shower into Eau Claire, though the best rain chances look to come east of the MPX area. Behind the front, there will be modest cold advection, but it`s just strong enough to bring our temperatures back down near normal, but not much more than that. For Saturday, we`ll see mainly cloudy skies by the afternoon as the trough currently moving into northern Montana swings through. This wave will be strengthening as it goes across MN and we`re seeing an increased signal for some light rain ahead of it along and south of the I-94 corridor, so did increase PoPs above what the NBM quite a bit to get some better precip mentions in the forecast for Saturday afternoon. It won`t be a washout, or very heavy, but most areas along and south of the I-94 corridor should see a brief period of light rain, with amounts under a tenth of an inch. For Sunday through Monday, we`ll see a trough come out of the Canadian Rockies that will deepen into a closed low over MN on Tuesday. We`ll be in line for this systems dry slot, so we won`t see much precip with it in the MPX area, but we will see plenty of wind. We`ll really start to see southerly winds pick up Sunday night, but it`s behind the cold front Monday afternoon through Monday night that looks to bring our strongest winds. Monday afternoon should see gusts in western MN up near 35 kts with deep mixing bringing down some stronger winds, but it`s Monday night that has the potential for the strongest winds. This is when we see an isallobaric high move in, along with strong CAA as winds switch from the west to northwest. GFS BUFKIT soundings show potential gusts over 40 kts in western MN, so we`ll have to watch this period for the potential for wind headlines. By Tuesday afternoon, we`ll see high pressure moving in from the Dakotas, with the winds and gusts starting to pull back. For the rest of the week, we`ll have lighter winds and cooler temperatures on Wednesday as high pressure moves through, but for Thursday and Friday, winds turn southerly and we`ll start to see highs in the 60s growing in coverage each day. It looks dry to end the week and if you`re looking for the potential for a stronger system, you need to look on the 10-12 day window. This is when a deep trough will be coming out of the Rockies, with the potential increasing for a more meaningful weather system for the local area around the 27th/28th of October. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 655 PM CDT Fri Oct 17 2025 Gusty SW`ly winds will continue to weaken this evening. The band of low VFR cu from earlier today has finally cleared RNH and EAU allowing for a brief period of a few high clouds to clear skies. Albeit these conditions will be short-lived as another frontal boundary approaches from the west overnight. Cloud cover is expected to gradually redevelop as the front moves eastward. Winds shift westerly by mid-morning followed by a NW`ly shift with increasing gusts between 18-25kts in the afternoon. Precip is possible with this front. As of now, AXN and STC have limited potential see any drops of rain however, better confidence exists farther to the south and east of those sites, thus prob30s have been introduced but will likely need to be upgraded to prevailing or tempo groups come the next routine issuance. KMSP...Winds will continue to weaken through this evening. A secondary front will pass through tomorrow morning causing winds to shift W`ly by mid morning then NW`y by the afternoon with gusts between 20-25kts. Introduced prob30 for light rain late tomorrow afternoon into the early evening, will likely upgrade to prevailing or tempo groups in the next routine issuance. /OUTLOOK FOR KMSP/ SUN...VFR.
