The warm-up is coming and it looks like we're not going to be able to avoid it.
Ed Shimon at the National Weather Service explains as we enter August, the Climate Prediction Center has Illinois solidly above normal for temperatures and below normal for precipitation.
Excessive heat warnings could come into the fold in August. Shimon explains an excessive heat advisory or even a heat warning could be issued at times this week.
While August is showing strong above normal temperatures trends, getting into September and October the trends are still above normal for temperatures but they are not as strong as for August.
