SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0633 PM CST Tue Nov 10 2020 Valid 110100Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF SOUTHWEST LOWER MICHIGAN AND NORTHERN INDIANA... ...SUMMARY... A line of thunderstorms capable of producing strong to locally damaging wind gusts will continue for a few more hours this evening across parts of southwestern lower Michigan into northern Indiana. ...01z Update -- Lower Michigan into Indiana... The Slight risk has been expanded eastward across parts of southwestern lower Michigan and northern Indiana. A well-organized line of storms with a history of wind gusts between 50-60 kt over the past 1-2 hours continues to track eastward this evening. This line of storms currently extends from southeastern portions of Lake Michigan southwestward into eastern IL. At least a brief period of severe potential will extend downstream where weak instability and strong shear is present. With time and eastward extent, the boundary layer should begin to stabilize with loss of daytime heating, and stronger forcing will begin to lift north/northeast of the area, lessening severe potential. Otherwise, the only other changes at 01z were to remove the Marginal risk across Florida where severe potential has decreased this evening, and to adjust the 10% general thunder line per latest observational trends. ..Leitman.. 11/11/2020
