Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 307 PM CDT Mon Jun 27 2022 .DISCUSSION...(This evening through Monday) Issued at 241 PM CDT Mon Jun 27 2022 KEY MESSAGES: (optional) - Marginal Risk of severe thunderstorms for western Wisconsin Tuesday afternoon - Marginal Risk of severe thunderstorms for west-central Minnesota Wednesday night. TODAY & TONIGHT: A healthy cumulus field has developed this afternoon, with a few hundred J/kg of CAPE across north-central MN resulting in a few isolated showers and thunderstorms. The thunder threat this afternoon will remain constrained to the Mille Lacs area & north of the US-8 corridor in west-central Wisconsin. Otherwise, a few sprinkles are possible with any of the deeper clouds this afternoon. More widespread showers and thunderstorms do appear possible overnight into Thursday morning, as a weak area of vorticity passes overhead & an increasing low-level jet provides some low-level forcing. This precipitation should remain fairly sparse in coverage, so only expecting precipitation amounts around a tenth of an inch. TUESDAY: A cold front will move through the region during the day on Tuesday, with isolated thunderstorms expected to develop along the front during the late afternoon and evening. The timing of the front means these thunderstorms should mainly be constrained to west- central Wisconsin and far-southeastern Minnesota. The thunderstorms Tuesday have the potential to become more organized thantoday's, as instability will be a bit higher with MLCAPE values around 1000 J/kg and shear along the front increases to around 30 kts. Most of west- central Wisconsin remains in a Marginal Risk for severe weather as the strongest storms could produce isolated large hail and brief damaging wind gusts. Otherwise, temperatures will be a few degrees warmer with highs in the mid 80s across western Minnesota and upper 70s across western Wisconsin. WEDNESDAY: Warm temperatures return Wednesday behind a warm front, as highs reach the mid 90s across western Minnesota and mid to upper 80s elsewhere. ANother chance for thunderstorms comes thursday night as a weak surface low tracks along the US/Canada border and drags a weak boundary through the region. Instability values will be much higher Wednesday owing to the warm temepratures, but capping during the afternoon will limit any thunderstorm develop until later Wednesday night across the Dakotas. If thunderstorms do develop, they will likely form some form of convective complex along the front, and could move into western and central Minnesota late Wednesday night. Portions of west- central Minnesota remain under a Marginal Risk for severe weather Wednesday night, with damaging wind gusts the possible threat. THURSDAY-THE WEEKEND: temperatures remain warm and muggy on Thursday, but return to more seasonable values through the weekend with broad high pressure generally over the region. There is a chance of thunderstorms Thursday depending on the timing of the front, but a quicker frontal passage could keep Thursday mostly dry. Otherwise, mostly dry conditions are expected until Sunday, when general summertime thunderstorm chances return. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 100 PM CDT Mon Jun 27 2022 VFR through tonight with FEW/SCT high-based cumulus this afternoon. Scattered rain showers are possible overnight into tomorrow morning, with the greatest chance for light rain setting up from central Minnesota into west-central Wisconsin. Included a PROB30 mention for now at most terminals, but a TEMPO or prevailing group continues to trend towards showers being more likely.A few rumbles of thunder can not be ruled out as well, especially across western MN. WInds will be westerly around 10 kts through this evening, with speeds diminishing after sunset. Winds briefly become more southerly overnight,with a wnd shift to northwesterly expected by the end of the period. KMSP...The best chance for a few showers, and perhaps a thunderstorm, will be between 5-9 AM tomorrow morning. /OUTLOOK FOR KMSP/ Wed...VFR. Wind S 10-15G25 kts. Thu...Chc -TSRA/MVFR.
