The National Storm Prediction Center has outlooked for a slight risk of severe storms (yellow-shaded area on map above) this coming Monday a broad area of the U.S. from the gulf coast states north into a good portion of Illinois and Indiana. As an intensifying low pressure system develops over the Texas Panhandle and moves northeast, strong southerly flow will feed abundant moisture from the Gulf of Mexico into the system.
A strengthening south-north jet stream aloft will provide additional instability and create conditions conducive to strong, possibly severe storms as far north as southern and central Illinois and Indiana. Chicago currently rests on the northern edge of the slight risk outlook area, but this is early in the process and the severe storm area could easily shift farther north or be depressed south, depending upon the actual movement and intensification of the low pressure center.
