Overview

A strong low pressure system impacted much of the region from the morning of November 4th through November 5th. This storm not only brought along much needed rainfall, but it also brought along some severe weather. The morning of November 4th, a few cells grew strong rather quickly and resulted in sporadic reports of hail between quarter and ping pong ball sized. Some reports of wind damage were also received. The bulk of the precipitation fell on the 4th. A large swath of 1-4" of rain fell, with the highest totals along an axis from Ottumwa to Dubuque IA. As much of the rain began to move out the morning of November 5th, the dry lot associated with the cold front punched through the area. That, coupled with some likely influence from the low level jet, led to a rapidly strengthening line of severe convection. While little to no lightning was noted with this line, multiple reports of severe wind gusts and damage were received.
