Issued 249 AM CDT Mon Sep 30 2024 Wednesday through Sunday: Temperatures will warm back into the 70s on Wednesday as the high begins to push east of the area, and then into the mid 70s on Thursday ahead of another cold front. This front will bring a low chance (less than 30 percent) of showers to the region Thursday night or early Friday. Highs Friday will be a touch cooler, in the upper 60s to around 70. High pressure behind this front looks to bring quiet and pleasant conditions for at least the first half of the weekend. Another front will start to take shape to our west during this time, with some discrepancy as to whether that frontal passage will take place late in the weekend or early next workweek. Boxell && .AVIATION... Issued 249 AM CDT Mon Sep 30 2024 Patchy ground fog is expected this morning, especially at the more rural airports. This should dissipate an hour or so after sunrise, with light winds and VFR conditions expected through the day today. VFR will prevail tonight into Tuesday morning, with a strong but dry cold front passing through the region before sunrise on Tuesday. This will bring gusty northwest winds to the area for much of the day on Tuesday. Boxell && .MARINE... Issued 249 AM CDT Mon Sep 30 2024 Low pressure over the Canadian Prairies will progress toward Hudson Bay as it deepens today. The low is forecast to linger over Hudson Bay on Tuesday, dragging a cold front across Lake Michigan during the morning hours Tuesday. Scattered showers are expected over the northern two-thirds of Lake Michigan along and ahead of the advancing front. Gusty northwest winds will quickly become established behind the front on Tuesday. Gales are not expected at this time, though winds to around 30 knots are likely over the southern third of the lake. A Small Craft Advisory is in effect. High pressure will then push through the central Plains and lower Missouri Valley Tuesday, before moving into the Mid Atlantic on Wednesday. Winds will turn more southerly Wednesday in response, with increasing gusts over the northern half of the lake. Another front is then expected Thursday into Friday, with northerly winds expected behind the front. Boxell && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
