The strong upper level system that has produced a wide variety of weather over the center of the nation will continue to move eastward. The graphic from the NWS shows the plot of the morning balloon data at 500mb (18000 feet). By Monday morning the system will stretch from Michigan southward, and it will move off the New England coast Tuesday morning. Surface high pressure with much cooler and drier air will follow in the wake of the system.
The system was responsible for the blizzard with 3+ foot snow amounts over the western parts of the Dakotas, tornadoes up to 1 mile wide in western Iowa, and heavy rain and storms associated with the warm and cold fronts. There is a continuing small risk of severe storms this Sunday afternoon over the eastern Midwest. In the mean time tropical storm Karen weakened along the central Gulf coast.
For the Chicago metro area, heavy rains and localized severe weather moved over the central part of the metro area Saturday afternoon. A list of area rain reports can be found here, with severe reports found here. A few showers are possible tonight and Monday morning as the upper level system moves through. The rest of the week looks dry, with seasonal temperatures. That means highs from the mid 60s Monday rising to the mid 70s by Thursday.
