436 FXUS63 KMKX 031533 AAA AFDMKX Area Forecast Discussion...UPDATED National Weather Service Milwaukee/Sullivan WI 1033 AM CDT Fri May 3 2024 .KEY MESSAGES... - Rain and thunderstorm chances Saturday afternoon into Saturday evening, followed by additional precipitation chances for the middle portions of next week. && .UPDATE... Issued 1032 AM CDT Fri May 3 2024 The low clouds cleared out of southeast WI and we have sunny skies. Drier air is moving in and dewpoints are dropping into the lower 40s. With high pressure moving in and lighter winds, a lake breeze is already getting established. This will move inland through the afternoon as the general flow becomes easterly. Cronce && .SHORT TERM... Issued 215 AM CDT Fri May 3 2024 Today and Tonight: Drier airmass moves into southern Wisconsin today. Clouds will hold on over eastern portions of the forecast area early this morning, but expect to give way to mostly sunny skies by late this morning and afternoon. Generally clear skies are expected for tonight. Light winds also become established through tonight with weak surface high pressure. KPL && .LONG TERM... Issued 215 AM CDT Fri May 3 2024 Saturday through Thursday: Models remain in fairly good agreement for this weekend and Monday. Next mid level shortwave trough still expected to impact southern Wisconsin by Saturday afternoon. It is a quick mover, but it should provide lift over the area through early Saturday evening. Thinking enough daytime heating and surface moisture convergence will lead to at least scattered thunderstorm coverage in this time range. Will mention this in our messaging, but not sure all parameters are there for anything more than a few strong thunderstorms. Southern Wisconsin then gets another cold frontal passage in the early to mid evening hours on Saturday. More dry air behind this front for clearing and cooler temperatures Saturday night. Rising heights aloft for Sunday into Monday for dry and warm conditions across the forecast area. The unsettled part of this forecast looks to be Tuesday through Thursday with a broad upper level trough setting up over the northern plains. Energy rotates around this trough into the great lakes beginning on Tuesday. Lower and mid level moisture will be in place for the potential of widespread rain and embedded thunderstorms, especially Tuesday afternoon and evening. Will continue to watch timing of this potential event. The mid-week pattern should keep temperatures near or slightly below normal on Wednesday and Thursday with at least some showers and thunderstorms persisting across southern Wisconsin. KPL && .AVIATION... Issued 1032 AM CDT Fri May 3 2024 The low clouds moved out and clear skies will prevail through Saturday morning. A lake breeze is already getting established, so the wind shift at MKE may be earlier than 18Z. Winds will be light and become more easterly later this afternoon through tonight. A line of storms is possible Saturday afternoon. Cronce && .MARINE... Issued 215 AM CDT Fri May 3 2024 Showers exit Lake Michigan this morning. High pressure of 30.1 inches and lighter winds are expected later this afternoon and tonight. Some low level moisture returns on Saturday ahead of a cold front. This front will move across Lake Michigan on Saturday evening, before high pressure around 30.1 inches again moves into the region for Sunday. Winds are expected to be light to breezy across Lake Michigan through the upcoming weekend. KPL && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
