SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0753 PM CDT Mon Sep 20 2021 Valid 210100Z - 211200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM CENTRAL WISCONSIN SOUTH-SOUTHWESTWARD TO CENTRAL MISSOURI... ...SUMMARY... A couple of severe thunderstorms -- capable of producing locally damaging wind gusts and hail -- will continue through mid evening across parts of the Upper Mississippi Valley southward to central Missouri. ...Discussion... A semi-continuous line of thunderstorms is ongoing at this time from western Lake Superior south-southwestward to far southeastern Kansas, near the advancing cold front. While this band of storms is expected to continue through the overnight hours, limited instability -- diminishing gradually with the loss of daytime heating -- is indicated across most of the region. As such, severe-weather potential is also expected to continue to gradually wane through the evening hours. In the mean time however, will maintain a narrow corridor of SLGT risk, from central Wisconsin to central Missouri, to reflect the zone of greatest potential for damaging winds and/or hail. ..Goss.. 09/21/2021 Read more LIVE: spc.noaa.gov
