Daytime highs will range between five and fifteen degrees above normal. - Dry conditions prevail through most of the week, with the next chance for showers and storms this weekend. && .SHORT TERM... Issued 326 AM CDT Mon Sep 16 2024 Today through Tuesday: More localized ground fog is expected to linger in the usual low lying areas into this morning, especially east of the Kettle Moraine. Otherwise, a 500 mb high will linger well to the east of the region into Tuesday, with a 500 mb trough becoming negatively tilted as it shifts through the Central Rockies. This should allow surface high pressure to remain stacked with the 500 mb high, and low pressure to linger over eastern Montana. This should result in continued middle to high clouds pushing northward through the area at times, with sunshine mixing in as well. Well above normal temperatures will continue, with highs into the middle to upper 80s inland today and Tuesday, and somewhat cooler near Lake Michigan with onshore winds. May see more ground fog overnight tonight in the usual low lying areas. Wood && .LONG TERM... Issued 326 AM CDT Mon Sep 16 2024 Tuesday night through Sunday: Ensembles continue to suggest that the remnants of the tropical cyclone moving into the Carolinas and Central Appalachian Mountain region should remain to the east and southeast of the area Tuesday night into Wednesday. An amplified skinny ridge axis at 500 mb should develop over Wisconsin Wednesday into Thursday, which should maintain dry conditions and continued very warm temperatures. Onshore winds should keep areas near the lake a little cooler once again. Ensembles suggest that the 500 mb flow should try to become more zonal Friday into the weekend, with low pressure possibly shifting northeast either through or to the northwest of Wisconsin. A lot of uncertainty here with the details, but this may be our next decent chances for showers and some thunderstorms. Temperatures look to remain warm into the weekend. Wood && .AVIATION... Issued 326 AM CDT Mon Sep 16 2024 Localized ground fog in the usual low lying areas should linger into early this morning, and may occur again overnight tonight into early Tuesday morning. Otherwise, middle to high clouds should push northward through the area at times today into Tuesday, with plenty of breaks in the clouds. Light to modest southeast winds are expected today and Tuesday, with light and variable winds tonight. Wood && .MARINE... Issued 326 AM CDT Mon Sep 16 2024 High pressure around 30.3 inches over the Northeast and low pressure around 29.4 inches over eastern Montana will remain fairly stationary into Wednesday. The high will weaken to around 30.0 inches Thursday, with the low strengthening to around 29.3 inches. Light to modest south to southeast winds are expected over the lake during this time. Low pressure may approach the region sometime this weekend. Wood && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
