November SVR Warnings
Posted: 12 Nov 2026 05:30 AM, Views: 550Tags: nov
An area of early morning thunderstorms brought plenty of hail to southeastern Iowa into Illinois. While the vast majority of the hail was of the small and nuance kind, a couple of one inch hail reports were received by the NWS near Davenport. The NWS issued a couple of Severe Thunderstorm Warnings to cover the largest hail and such warnings are somewhat rare during the month of November. The featured map presents an IEM accounting for the average number of such warnings during November by county since 2001. Certainly far southeastern Iowa has the highest frequencies as the location is the most likely to experience the warmest and most humid conditions during the month. Such conditions were not necessarily the driver for the early morning activity on Wednesday, but rather a quick moving mid-troposphere disturbance with cold air aloft allowing for thunderstorm development.
