In the last 7 days, Illinois has received 1 to 3 inches south of Interstate 70 (map below). Most of that came from storms last weekend. However, the precipitation amounts dropped off rapidly northward in Illinois. Areas in the northern third of the state received little to no precipitation. We are keeping a close eye on the continuing dry conditions in northern Illinois. That area has been persistently dry for several months despite this winter’s snowfall.
Temperatures in the last 7 days have been well above average. The pattern of temperature departures across Illinois (map below) was interesting with the largest departures in northern Illinois (6 to 8 degrees above average) and the smallest in southern Illinois (2 to 4 degrees above average). This reflects the cloudy, rainy conditions in southern Illinois, especially last weekend.
