Low pressure around 29.5 inches over northwest Wisconsin will continue to gradually weaken as it moves northeast across Lake Superior into Ontario this afternoon. Gusty south winds are expected across Lake Michigan today, with a few gusts approaching or reaching gale force, especially in the northeast portion of the lake. Winds will then gradually shift from southwest to northerly tonight as a cold front tracks south, but southerly winds will continue over far southern Lake Michigan as the front stalls. Brisk northeast winds will then prevail over central Lake Michigan on Sunday with lighter winds in the north, and variable winds in the south where the stalled front remains. Modest east to southeast winds will then develop over all of the lake Sunday night as the stalled front moves north as a warm front. Brisk east winds, possibly reaching gale force, are expected over the northern tip of the lake late Sunday night into Monday morning. Breezy south winds will develop over the remainder of the lake on Monday. Rounds of showers and thunderstorms are expected tonight into Monday morning. A few of these storms could produce locally gusty winds and hail.
