An area of high pressure is off to the east and an area of low pressure is located in the Dakotas. In between the two systems, ample moisture is being sucked up from the Gulf of Mexico. A warm front has moved thru Chicago and temperatures are expected to range from the mid 80s to the lower 90s for the next couple of days with dewpoint values in the upper 60s. However, this will cause the atmosphere to become quite unstable during this timeframe. Scattered showers and thunderstorms are expected to develop in the northern Illinois area. Some of these storms could reach severe limits with damaging winds and hail. In addition, because the atmosphere is so juicy, these storms will have heavy rain potential with them.
