Partly to mostly cloudy skies continue away from Lake Michigan tonight, which will help to limit our cooling overnight. After some patchy morning fog Saturday, we should see plenty of sunshine into the afternoon as temperatures soar to around 90 degrees. With minimal wind to mix the lower atmosphere, air quality alerts continue in our lakeshore counties and in Kent County. With green flags flying and water temperatures in the middle to upper 60s, the lakeshore will be a great place to beat the heat Saturday unless you're in the groups sensitive to the air quality alerts. While it's not that humid now, dew points crawl into the lower 60s Saturday then the middle 60s Sunday. This means it will also feel a little more sticky as well.

While a stray shower or thunderstorm is possible Saturday afternoon/evening, an incoming system initiates multiple thunderstorms Sunday afternoon. Sunday will probably play out as a period of showers in the early morning hours followed by a quick return to sticky sunshine. Thunderstorms then develop from late afternoon and beyond ahead of an approaching cold front. Severe weather looks more likely to our south, but a couple of strong storms are possible. If any storms were to overperform a bit, gusty winds and hail could be on the table.

Low pressure resides on top of the Mitten Monday before inching out over western Lake Erie Tuesday. Its close proximity should lead to widespread showers and a great chance at much needed rainfall. Right now, rainfall expectations for Sunday and Monday combined look be be at least 0.5 to 1 inch, with some likely surpassing 1 inch. Every drop is huge, as it begins to chip away our growing deficit. Sunshine and a warm-up start by the middle of next week. Long-range trends show cooler and dry weather for next weekend and into the Fourth of July.

Join chief meteorologist Keith Thompson from 6 to 10 a.m. Saturday morning!
