The National Weather Service Milwaukee/Sullivan has issued a Hazardous Weather Outlook for parts of east central, south central, and southeast Wisconsin. According to the NWS forecast, residents can expect chances of thunderstorms at times across southern Wisconsin this morning and across central Wisconsin in the afternoon today.

This morning's fog and mist have given the Milwaukee area a noticeably humid start with a humidity of 84%. While the weather is set to clear up to become partly sunny with a high near 68 degrees Fahrenheit today, the calm will be relatively short-lived. There's a 20% chance of showers later tonight, along with mostly cloudy skies and a low around 57 degrees.

Looking ahead to the rest of the week, more thunderstorms are in the forecast. Friday and Saturday continue the trend, with a 30 percent chance of rain and the possibility of showers and thunderstorms before the night is through. The daytime temperature should peak at around 68 degrees Fahrenheit, with a steadfast northeast wind around 10 mph.

Weekend warriors should keep an eye on the sky, as there is a slight chance of showers on Saturday, with thunderstorms also possible after 1 pm. Despite this, the high should hover around 70 degrees, accompanied by a light northeast wind. Sunday appears to be relatively stable before another 20 percent chance of showers emerges in the evening, while Monday could warm up to 75 degrees.

It seems like the uncertain weather is setting up camp for the longer haul, with the NWS predicting a 40% chance of showers and thunderstorms by next Tuesday, increasing to 60% that night with potential thunderstorms. By Wednesday, the chance of showers and thunderstorms rises to 50 percent with highs near 80 degrees, so keep those umbrellas at the ready.

The Hazardous Weather Outlook has not called for spotter activation, suggesting that while the weather may be a nuisance, severe conditions are not expected at this time.
