November Moderate Risks

Posted: 29 Nov 2022 05:26 AM

The Storm Prediction Center has a convective moderate risk issued for today over portions of Mississippi and surrounding states. The featured map presents a heatmap of such "day 1" moderate risks during November based on unofficial IEM archives. Such events during November are rather rare with only 15 events found since 2002, but this is the second event for this November with the other happening on 4 November. The heatmap nicely shows the two areas of enhanced severe weather climatology for this time of year as they are favored battle grounds between warm/moist and cold air masses. Iowa will be miss out on the severe weather today with snow expected over northern Iowa and a quick drop in temperatures that will likely cause travel headaches.
