After a little bit of a humid Wednesday, Thursday has turned into a spectacular afternoon! After a very comfortable start and temperatures falling into the mid-50s afternoon highs reached the upper 70s, to right around 80 degrees. We are beginning to see a few upper-level clouds move in as showers develop well to our northwest. Over time, the cloud cover will increase which will turn our skies mostly cloudy by Friday morning. Until then, temperatures are expected to remain very comfortable Thursday evening and there should be no issues with the weather if you have any outdoor plans.
But if you're plans take you outdoors Friday, you'll want to keep tabs on the forecast as a few showers and isolated thunderstorms could roll through during the afternoon and evening. The morning will start off with a bit of cloud cover followed by a few showers mid-morning. These will be left over from a weakening storm complex from the Upper Midwest Thursday night. Conditions will then clear out early afternoon but with dew points rising into the upper 60s it'll feel a little more humid. An incoming cold front late in the day may be enough to trigger a few thunderstorms during the late afternoon and evening, beginning across northwest Illinois and moving east through sunset.
Widespread rain and thunderstorms are not expected but isolated thunderstorms after 4pm or 5pm could be enough to interrupt some evening plans, including night one of the high school football games. While not a washout, you'll want to remain updated on the forecast and radar through the evening. The threat for thunderstorms should decrease after sunset.
There remains a marginal risk, level 1 out of 5, for isolated severe storms during the afternoon and evening. Biggest threats with any storms that do reach severe limits would be damaging winds and large hail. But an isolated tornado threat can't be entirely ruled out.
