Thunderstorms and Heavy Rainfall in the Mid-Atlantic; Fire Weather Concerns in the West

Thunderstorms are expected to bring heavy rain and potential significant flash and urban flooding to the Mid-Atlantic on Thursday, especially along the I-95 urban corridor.

Overview

Thunderstorms developed in two rounds, ahead of an advancing cold front and along a warm front.  Many of the storms were elevated, and their primary impact was large hail, including reports of larger than baseball sized hail in Osceola, Iowa. This supercell along the warm front later went on to produce a tornado that produced damage in Warren and Marion Counties. Based on eyewitness accounts and video evidence, it is likely that this tornado was intermittent and not a fully continuous path. For simplicity, this will be noted as a single path.
