Warm, rather active pattern...
In the wake of yesterday’s outbreaks of showers and thunderstorms, weak high pressure takes hold today. A dry day is expected, with temperatures at early Summer-like levels on this first day of June, the start of meteorological summer.
Another frontal system will move back into the area for the middle part of the week, and bring the threat of additional showers and thunderstorms while a warm and humid pattern continues. Currently, there is a slight risk that some of these storms could become severe northwest of I-55 as early as late Tuesday night, elsewhere late Wednesday, and north of I-70 Wednesday night.
Meanwhile across the Corn Belt, the combination of warm weather and abundant soil moisture remains favorable for corn and soybean emergence and growth.
