The risk for severe weather returns to the region Monday afternoon, though the bulk of the severe weather is forecast to occur south of the local area in eastern Iowa and Illinois. With the local area residing on the north side of the severe weather risk area, there is increasing uncertainty on the coverage and severity of the storms, driven by how any morning storms unfold. If conditions line up just right, there is a narrow window in the mid to late afternoon for storms to produce large hail, damaging winds, and a few tornadoes. Bottom line, stay weather aware through the afternoon on Monday and be ready to seek indoor shelter should severe storms approach your location.
Pleasant conditions are expected for today with highs generally in the 60s to lower 70s for most. Showers and storms return to the forecast overnight Sunday and into Monday with some potential for storms to be strong to severe south of I-90 on Monday afternoon and evening. Temperatures cool down into mid-week with highs in the 50s to lower 60s and morning lows in the 30s by Wednesday, possibly even below freezing in some locations.
