Cooler and less humid air is finally beginning to blow in from the northwest this evening. A few lingering showers and thunderstorms may develop in IL, KY and TN until about sunset but skies will clearing and temps dropping overnight. By Monday morning it should be mainly clear and refreshingly cooler, with daybreak lows in the low 50s to around 60. Monday will give us a nice but brief break in the heat and storms….with highs mainly in the 70s and noticeably lower dew points. By Tuesday warmer air and the threat of active weather will be returning.
Overall the week ahead is looking quite volatile, stormy and wet for much of the nation as a deep upper trough gets stuck in the west and strong southwest flow develops over the middle of the country. Flooding and severe weather looks likely across much of the plains and Midwest. However, we will probably miss out on most of it…as we come under the influence of a big upper ridge over the southeastern part of the country. The exception for us looks to be late Tuesday into early Wednesday as a strong system brushes the Heartland. It looks like we’ll have a line or two of showers and storms with heavy downpours and strong storms possible. Then later next week it gets very warm and humid…but should stay mostly dry.
