Frost Advisory in place early, windy and warm Earth Day ahead

It's another chilly late-April morning for many as frost advisories stretch from the Oklahoma/Arkansas border to Cape Cod, Massachusetts.

The portion that includes all of our northern Illinois counties runs until 8AM. 

With Monday's forecast comes a mixed bag of news, including an increasing southwest wind, increasing clouds, and a quick warm up. 

The best chance for sunshine will be during the morning hours as clouds are expected to gather up after the mid-day hours. This, along with a rather robust southwesterly wind will help temperatures warm nicely into the upper 60s. 

Forecast models then show the first of two early-week opportunities for rain moving in tonight, primarily between sunset and midnight. 

This will be in the form of a few light showers, with most of the precipitation staying north of the Illinois/ Wisconsin border. The second comes with a cold front which looks to slide through the region late in the afternoon Tuesday. 

Tuesday's chance will have a bit more "ummph" to it, allowing a few non-severe storms to be possible. All in all, the heaviest rain looks to occur well south of the region in central Illinois. 

We then cool off for the middle of the week as highs go from the upper 60s to the low 50s. This cool down is brief as highs look to climb back into the 60s starting Thursday, then 70s starting Saturday. With this massive warm up comes an active stretch of weather that will bring the chance for storms Friday, Saturday, and Sunday. 

In the Storm Prediction Center's latest long-range severe outlook, they have taken the entire Stateline out of the 15% risk. Areas west of the Mississippi River remain under what is equivalent to a level 2 slight risk for severe weather.

Changes are expected in the coming days, so make sure to check the forecast frequently!
