Issued 745 PM CDT Wed Jun 4 2025 No major chances to the forecast at this time. Some fog over the lake may sneak onto the nearshore areas tonight but little to no impacts are expected from this. Kuroski && .SHORT TERM... Issued 229 PM CDT Wed Jun 4 2025 Tonight through Thursday night: Afternoon cumulus will decrease by early evening with the loss of daytime heating, with mainly high clouds then expected overnight. Dry weather will continue on Thursday under high pressure, with increasing mid and high level clouds by the afternoon hours. Will likely see another round of diurnal cumulus as well. High temps will be near normal, aside from a few degrees below normal near the lake under onshore winds. Short term models continue to show near surface smoke potential continuing tonight into at least early Thursday. The Air Quality Advisory was extended until noon tomorrow as a result. DDV && .LONG TERM... Issued 229 PM CDT Wed Jun 4 2025 Friday through Wednesday: A pair of weak shortwaves are expected to move through late week, with low end shower/storm chances returning Friday into Saturday. Surface high pressure centered just to the northeast may provide enough subsidence and low level dry air to keep southern Wisconsin dry, so kept precip chances generally less than 25 percent. High temps will be within a few degrees of normal Fri/Sat, except for cooler conditions near Lake Michigan under onshore winds. A pair of stronger waves are then expected Sunday into Monday, with a little better moisture surge ahead of the Sunday system. Shower/storm chances are thus on the higher end (50-80%) Sunday, with enough forcing and lingering moisture for a 40-60% chance of showers and storms Monday. There remain some differences among models with the finer details of timing with the highest precip chances, but overall confidence is increasing for a couple rounds of showers/storms Sunday and Monday. Near normal temps Sunday will cool off a few degrees for Monday behind the first system. High pressure will likely then bring a return of dry conditions Tuesday into Wednesday, with temperatures warming up through mid-week. DDV && .AVIATION... Issued 745 PM CDT Wed Jun 4 2025 May see some lingering visibilites less than 6 NM due to smoke through at least tonight, possibly into Thursday as well. Skies will then be mostly clear later tonight into Thursday morning, with increasing mid and high clouds by the afternoon, along with some scattered afternoon cumulus again. North to northeast winds will generally be less than 10 knots through Thursday. We cannot rule out some fog over the lake pushing inland a bit for a period later tonight with some MVFR CIGS near the shoreline in additiona to the smoke concerns. Kuroski && .MARINE... Issued 229 PM CDT Wed Jun 4 2025 High pressure of 30.0 inches over the western Great Lakes will largely stay put through Saturday, with mainly dry weather expected for this period. Winds will generally be light and variable across the north through Saturday, with northerly winds 10 knots or less across the south. Shower and storms chances are expected Sunday and Monday as a pair of shortwaves move through. Winds will be a bit more elevated during this time frame as these systems pass through the Great Lakes. Visibilities will be reduced a little at times tonight into Thursday due to smoke, with even lower visibilites possible if fog develops. DDV && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
