DISCUSSION

Issued at 240 AM CDT Sun Aug 31 2025

Dense fog has developed again this morning, but it is more confined to west-central MN this time around. Visibilities have been at a quarter mile or less since 10-11pm, and are not expected to widely improve until a few hours after sunset when surface temps can warm above saturation. Showers will remain to our south and west, making for another pleasant day across the region with limited cloud cover.

Monday should be largely similar to today, with highs in the 70s and pleasant conditions to end the long weekend. The strengthening trough will start to dig down from Canada, ushering in lobes of vorticity ahead of the main wave. This spin could provide enough forcing for scattered storms to develop Monday evening, primarily across western MN. The more widespread, and higher confidence, rain will come along the robust cold front Tuesday afternoon and evening. Winds will turn out of the southwest by Tuesday morning, but a lack of moisture transport ahead of the front is expected to limit QPF and any severe potential.

The main impacts from this front will be much cooler temps and gusty NW winds Wednesday all the way through Friday potentially. Thursday is slated to be the coolest day, with morning temps starting off in the upper 30s and low 40s. The NBM continues to gradually adjust highs lower for this stretch as it corrects from its summertime warm bias. It's very possible we struggle to climb above 60F, especially if cloud cover is expansive enough. This will definitely be a taste of fall, but we will start to rebound as we head into next week. There is no major signal for precipitation in the long term forecast past our mid-week system.
