KEY MESSAGES
- A west-to-east moving cold front will trigger a couple rounds of showers and storms today and tonight. Locally heavy rainfall is the primary threat
- Slightly cooler temperatures are on the horizon with rain chances returning Friday.
WEDNESDAY THROUGH FRIDAY
West/northwesterly flow will resume on Wednesday, with much drier air advecting in from the west. Dew point temperatures will fall back into the middle 50s with highs in the upper 70s, making for a really pleasant day. Much of the same can be expected on Thursday.
On Friday, winds will begin to turn more to the southwest. As a result, moisture values will increase ahead of the next frontal boundary that will move through Friday evening/overnight timeframe. Low-end chances of showers/storms return the the forecast on Friday.
AVIATION /00Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 623 PM CDT Mon Sep 7 2026
A line of showers and embedded thunderstorms is oriented southwest to northeast across Minnesota this evening. Models have this precip dying off over the next couple of hours before a strong LLJ kicks in ahead of a cold front and sets off another round of showers and storms after midnight. The coverage is the big question, so have opted to stick with PROB30 mentions for now. Winds have been gusty out of the southeast this evening and they should slowly trend down and go more southerly and eventually southwesterly as the front approaches late tomorrow morning. Outside of the overnight shower chances, VFR conditions are expected through the period.
KMSP...Showers are approaching from the west and should arrive sometime in the next 1-2 hours. Kept a mention for LLWS with the strengthening LLJ overnight and maintained the PROB30 early tomorrow morning, but did move it back an hour. Winds so southwesterly late tomorrow and models are hinting at another round of convection in the evening, but confidence is much too low to include mention for now.
/OUTLOOK FOR KMSP/ WED...VFR. Wind WNW 15G25kts. THU...VFR. Wind SW 5-10kts. FRI...VFR. Wind SW 10-15G25kts.
