Update

Issued 639 AM CDT Sat Oct 24 2026

The fog has dissipated a bit in coverage this morning, but patchy dense fog still remains north of Milwaukee. Thus the Dense Fog Advisory remains in effect until 9 AM for Sheboygan, Ozaukee and Washington Counties. Otherwise partly to mostly cloudy skies and mild temps will continue today and Sunday as upper ridging builds over the Great Lakes then shifts ewd in response to the large occlusion from Manitoba to Hudson Bay. A Canadian cold front will then pass Sun nt with temps returning to near normal for Mon-Tue.

Short Term

Issued 1030 PM CDT Fri Oct 23 2026

Tonight through Saturday night:

Light southeasterly winds and lingering humidity over Lake MI have formed a bank of fog and low stratus clouds drifting into Sheboygan county and points north. METARS and DOT cameras confirm the fog is dense in Sheboygan County, and a Dense Fog Advisory will remain in effect through 9 AM Saturday morning (unless trends warrant a change). An expansion of this Advisory southward into Washington and Ozaukee counties later tonight is possible, given GOES Night Fog RGB composites and surface observations are beginning to indicate a southward creep to the fog over time, mainly along and east of the Kettle Moraine hills. We could even see this fog continue south into the MKE metro late tonight, though forecast confidence is low.

The combination of continued airflow at the surface, abundant high- altitude cloud cover, and weak terrain-locking of the Kettle Moraine hills should prevent any fog formation further inland. From a Fond du Lac to Walworth line westward, looking fog free for tonight at this time.

Into post-dawn Saturday morning, winds turn due south and accelerate slightly, clearing away any lingering fog. Additional periods of broken high-altitude cloud cover are anticipated through Saturday and Saturday night, but dry weather continues all the same. Highs in the low 70s expected inland; some shoreline ventilation (SSE winds) could hold highs to the mid 60s for far eastern WI.

Long Term

Issued 1030 PM CDT Fri Oct 23 2026

Sunday through Friday:

Low pressure tracking east across Hudson Bay Canada this weekend will drag a cold front into WI. The front should reach northwestern portions of WI by late Saturday night into Sunday morning, with strong high pressure over Saskatchewan then forcing the front across southern WI later Sunday through Sunday night. Predominantly dry weather is expected to accompany the frontal passage, and the late arrival of the front allows daytime highs to reach the low 70s Sunday. CAA behind the front kicks in late Sunday night into Monday, with northeasterly winds off the lake. As such, central and eastern WI are forecast to observe highs in the 50s, with highs in the mid 60s further west along the southern edge of the state.

Meanwhile on Monday, a 500mb shortwave trough will dig into the central Great Plains, phasing with the aforementioned frontal boundary to seed surface low pressure. This low pressure looks to lift northeast into Monday night, bringing some 5-15% rain chances to the CWA. The bulk of the QPF and higher precip chances with this system land in MN and northwestern WI, leaving us predominantly dry as it passes. The remnant baroclinic zone from that activity then sets the stage for an additional upper trough and surface low to slide northeast from the Plains midweek. The placement of precip with this second system is less certain, but could track through the same corridor of MN / NW-WI or further east. ~15-30% precip chances are forecast for the CWA Wednesday until ensembles converge on a system track. In any scenario, we will be in the warm sector of both passing systems, resulting in a warming trend towards midweek.

This same pattern looks to continue later this week, with additional rain chances.
