Summer activities in full swing this weekend, and if you are planning on heading out to any of them you'll want to keep your eyes on the radar.
By Friday, a series of upper level waves will be pushing through Illinois, and bring with them the threat for storms. Hail, wind, and heavy rain will all be of concern Friday, with ample moisture and instability present. A few strong storms will be possible, and there is an isolated severe threat. However, the higher chance is highlighted under the yellow 'slight risk' for Friday just west of Illinois, through Iowa, northern Missouri, and eastern Nebraska.
Saturday will be of bigger concern, as an area of low pressure deepens as it moves into the area. The system's front also moves overhead, which would provide low level shear, or spin, in the atmosphere. Along with that, there will be ample CAPE (energy) and deep layer shear, that will bring a threat for all types of severe weather possible. Models are still not in agreement on timing of the storm development, though at the moment the best time frame would be early evening. The Storm Prediction Center has the area under a slight risk for severe storms on Saturday.
We'll make sure to keep updating you as more information comes out, but for now make sure to enjoy our sunny Thursday!
