205 FXUS63 KMKX 101459 AAA AFDMKX Area Forecast Discussion...UPDATED National Weather Service Milwaukee/Sullivan WI 959 AM CDT Wed Jul 10 2024 .KEY MESSAGES... - Scattered thunderstorms (around 30% chance) this afternoon and again and tomorrow. - Increasing potential for above average temperatures this weekend and early next week. && .UPDATE... Issued 959 AM CDT Wed Jul 10 2024 It looks quiet through at least late this morning. A weak shortwave on the back side of the remnants of Hurricane Beryl may kick off a few storms this afternoon, particularly from Madison westward. Temps will be near normal today, warmest in the west where there will be more sunshine. In general, the forecast looks on track for the rest of the day. DDV && .SHORT TERM... Issued 245 AM CDT Wed Jul 10 2024 Today through Thursday: The remnants of Beryl will continue to lift northeastward, reaching the eastern Great Lakes by this afternoon. Light rain will continue early this morning over far southeastern Wisconsin. A mid level disturbance currently located over Minnesota will then dig south into Iowa and northern Illinois by early this evening. This should aid in the development of scattered, diurnally driven thunderstorms across much of southern and south central Wisconsin. The greatest coverage will be south and southwest of the Madison area. Highs today should top out around 80, with lows tonight in the low 60s. Thursday will feature similar temperatures, with another chance (25-30%) for widely scattered afternoon thunderstorms. Boxell && .LONG TERM... Issued 245 AM CDT Wed Jul 10 2024 Thursday night through Tuesday: Mid level height rises will limit rain/storm chances Friday, with PoPs currently less than 15 percent. Highs will be a bit warmer, with mid 80s expected. Southerly flow and warming temperatures aloft will help boost temperatures through the weekend and early next week, with mid to upper 80s expected Saturday, and highs around 90 on Sunday and Monday (and potentially into Tuesday depending on the timing of a cold front). A considerable increase in dewpoints into the 70s from Saturday afternoon through Sunday will bring heat index values to near Advisory levels (~100 deg) for Sunday and Monday. Rain chances on Saturday may depend on the evolution of convection over the High Plains Friday night, with some models hinting at a convectively modified shortwave moving into the area later Saturday. Additional storms will be possible Sunday through Tuesday, but with considerable uncertainty regarding timing and strength at this distance. Boxell && .AVIATION... Issued 959 AM CDT Wed Jul 10 2024 It looks quiet through at least late this morning. A weak shortwave on the back side of the remnants of Hurricane Beryl may kick off a few storms this afternoon, particularly from Madison westward. Precip will wind down this evening, with dry weather likely overnight as high pressure builds in from the west.

DDV && .MARINE... Issued 245 AM CDT Wed Jul 10 2024 The remains of Beryl will reach the eastern Great Lakes this afternoon. North winds may briefly approach gale force over the far southern portion of the lake early this morning. Winds will then ease later today and come around to northwesterly. Winds will grow light and variable Thursday night. Boxell && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
