DISCUSSION

Rain cleared the CWA just before noon today with breezy southerly and southeasterly winds gusting 25 to 30 MPH. Most places ended up with 0.20 to 0.40" with some embedded higher totals greater than a half inch. There are some breaks in the clouds, but overall expecting mostly cloudy skies which will help keep our temperatures in check. We won't be as lucky tomorrow with continued southerly flow aloft sending us ample warm, moist air. Apparent Ts may reach the mid to upper 90s across southern and western Minnesota with upper 80s to low 90s elsewhere. Precip chances have decreased for much of the daytime hours tomorrow. A subtle wave overnight may lead to some isolated showers and a rumble of thunder early Sunday for far western Minnesota. The better chance for showers and storms will arrive after sunset across western and central Minnesota into western Wisconsin as a low moves out of the Dakotas. This system will bring a cold front through the region, but the most it will do in terms of sensible weather impacts is lower Tds for Tuesday. This FROPA Monday afternoon will once again lead to some isolated showers along the boundary, mainly in western Wisconsin.

PoPs increase Tuesday evening with another shortwave moving out of the Dakotas. This will likely be another widespread light rainfall event like we saw early this morning with QPF amounts around 0.20" with localized higher totals. With the upper ridge shifting into the eastern CONUS, we will find ourselves with nearly daily chances of showers with embedded waves parading through. Temperatures will continue to be above normal in the low to mid 80s through the end of the period with PWATs running some 150 percent of normal. Those who were hoping September would bring Fall-like weather will have to wait.

AVIATION /18Z TAFS THROUGH 00Z MONDAY/

Issued at 107 PM CDT Sat Aug 29 2026

High ceilings spread across the MN/WI area this afternoon with some splotchy MVFR ceilings over central-eastern MN into western WI at initialization time. Any and all morning rain has shifted east of the WFO MPX TAFs, with no rain expected throughout this duration, thus have run with dry TAFs for all sites. Cloud cover is expected to remain overnight into tomorrow morning, mostly with mid-level ceilings for all sites north of RWF-MKT. Should winds drop off more than expected at the WI sites, pre-dawn fog may develop and result in visibility reductions. Avoided that scenario at this point but later TAFs may include as such. SE winds will be occasionally breezy/gusty through this afternoon, then will settle down to under 10kts this evening through sunrise Sunday.

KMSP...Based on satellite and observation trends, have included a TEMPO early on for MVFR ceilings as they have intermittently moved across MSP and been included in the observation. Such low clouds are expected to be scoured out mid-to-late afternoon, resulting in VFR high ceilings from this evening through the day Sunday.

/OUTLOOK FOR KMSP/ MON...VFR. Wind S becoming NW 5-10 kts. TUE...Mainly VFR. Chc PM -TSRA/MVFR. Wind variable 5 kts. WED...VFR. Wind N 5 kts.
