KEY MESSAGES

- Dry weather under high pressure expected through the weekend and into next week. Fire weather concerns may increase into early next week.

- There is a high swim risk Saturday for Ozaukee, Milwaukee, Racine and Kenosha County lakeshore areas due to persistent and elevated onshore winds.

SHORT TERM

Issued 1140 PM CDT Fri May 29 2026

Current Overnight through Sunday Night:

The weather pattern is expected to remain unchanged this weekend as high pressure sinks southward from Hudson Bay into the Great Lakes by Sunday morning. Gusty east winds are expected today as a tighter pressure gradient remains over the region. These persistent onshore winds should also push cool lake air inland, with highs in the upper 60s to near 70 along Lake Michigan, and highs in the mid to upper 70s well inland. Expect partly cloudy skies from high clouds aloft.

The gusty easterlies are expected to drive high onshore waves, leading to High Swim Risk conditions this morning into this evening. Dangerous waves and currents will be likely and swimming is not advised while the Beach Hazards Statement is active.

Similar weather conditions are expected Sunday, with lighter winds as the high pressure center moves closer.

LONG TERM

Issued 1140 PM CDT Fri May 29 2026

Monday through Friday:

High pressure will retreat east somewhat on Monday allowing for some very low end shower chances (~20%) southwest of Madison Monday morning. However, another high pressure center is expected to dive south from Hudson Bay Monday afternoon into Tuesday, further reinforcing our stuck weather pattern. The high is finally expected to begin to shift east Wednesday, with southerly winds returning. Highs Monday through Wednesday will range from the upper 70s to low/mid 80s.

Chances for rain/thunderstorms look possible late week as a more humid air mass returns to the state and a trough slowly moves east across the state Thursday night through Friday.

AVIATION

MARINE

Issued 1145 PM CDT Fri May 29 2026

High pressure over the Upper Great Lakes will strengthen Saturday night and dominate the weather pattern into early next week. Breezy northeast to easterly prevailing winds will develop in the wake of a cold front overnight through Saturday, and again Monday into Monday night. Locally, the breezy east winds will lead to small craft advisory conditions this morning into this evening.

Winds will gradually become southerly on Wednesday as the high begins to exit and low pressure develops in the southern Plains.
