SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0738 PM CDT Sun Oct 11 2020 Valid 120100Z - 121200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER MIDWEST AND MID MISSOURI VALLEY REGION... ...SUMMARY... Severe thunderstorms remain possible through late evening across the Upper Midwest and Middle Missouri Valley. The primary risks are hail and wind. ...Upper Midwest/Middle Missouri Valley... Leading edge of stronger large-scale forcing for ascent is spreading across MN/western IA/eastern NE. Convection is increasing along the frontal zone in response to this forcing with several line segments now evident from western MN into eastern NE. 00z soundings ahead of the front (MPX, OAX, TOP) exhibit substantial inhibition, thus robust convection should hold close to the surging cold front. Damaging winds and some hail can be expected as the frontal squall line progresses eastward this evening. Have adjusted severe probabilities down along the cool side of the boundary. ..Darrow.. 10/12/2020
