Marine Weather and Tide Forecast for Cleveland, WI

SHORT TERM
Issued 126 PM CDT Sat Oct 17 2026

This Afternoon through Sunday night:

Northwest flow at 500 mb should become more zonal tonight into Sunday night across the region. High pressure is expected to slowly shift east northeast from the Central Plains into southern Illinois and Indiana into early this evening, then further to the east tonight into Sunday. Steady warm air advection on increasingly gusty southwest winds in the low levels will continue during this period, with mostly clear skies. This should hold low temperatures in the upper 30s tonight and help highs rise into the lower 60s on Sunday. Lows in the upper 30s to around 40 are anticipated Sunday night.

LONG TERM
Issued 126 PM CDT Sat Oct 17 2026

Monday through Saturday:

500 mb cluster analysis suggests that the 500 mb flow will remain fairly zonal over the region during most of the week, before a ridge axis develops over the region by Saturday. This setup will continue to allow high pressure to remain east northeast of the region for the first half of the week, with another high developing in the same area later in the week. This should keep the area dry for the week, which is supported by ensemble members.

Temperatures are expected to gradually rise through the week, with highs climbing well into the 60s early in the week, and around or in the lower 70s later in the week. Winds will be light to modest, which may allow for lake breezes/onshore winds each day near the lake.

A Small Craft Advisory is in effect later this afternoon into early Sunday evening for the nearshore waters north of Port Washington, for gusty southwest winds.
