310 PM EDT Tue Jul 15 2025
.MARINE...
Modest uptick in southerly winds this evening over northern Lake
Huron, with sustained winds reaching near 15 knots. Increasing low
level moisture tomorrow and daytime instability will produce
numerous showers and thunderstorms in the afternoon. Some of the
thunderstorms could be strong, producing localized wind gusts in
excess of 45 knots. Scattered-numerous showers and thunderstorms
likely persist Wednesday night, as low pressure and associated cold
front race east, passing through the Central Great Lakes Thursday
morning. North-northwest winds behind this system will likely top
out briefly in the 20-25 knot range over Lake Huron, which will
bring a chance of waves of 4 feet or greater to clip the nearshore
waters by Thursday evening. There may be just enough of an offshore
component to prevent small craft advisories however.
Winds veer around to the north-northeast Thursday evening, but
should be 15 knots or less by that time, with light and variable
winds for Friday as a large area of high pressure encompasses the
Great Lakes region.
