Key Points – Wednesday, July 19, 2017:
Synopsis: Good Wednesday morning! Much needed rains falling across central IL today…but the story is going to be the heat through the weekend, it’ll be the hottest week since summer 2013! We continue to see overnight lows forecasted in the mid to upper 70s, even lower 80s are on the able for western locations, not good for the crops this time of year (although there will be a little wind around). Isolated storms possible today with the heating of the day, the real focus will be to the north and west overnight because we are under the impression the storm cluster could take a southeast dive…can’t rule out a strong storm as well. The majority of the storm coverage will be to the north into the weekend, locations further south especially south of I-70 will stay drier, as the focus of the energy to the north. If you have any questions let us know, have a blessed day!
