Chronology of rains and storms Thursday, October 12


Wednesday evening update

A strong cold front is crossing the country and will reach the east coast on Thursday evening. We expect morning rain and heavy storms in the afternoon and evening across Maryland and the Mid Atlantic. A small chance that some of these storms will become violent. This may include dangerous lightning, damaging winds, small hail and a low risk of an isolated tornado.

Below is a quick look at the setup and simulation timeline for Thursday.

Backtracking for a moment: This system triggered several severe storm outbreaks in the central United States and the Upper Midwest, with Wisconsin leading and centering. This video was captured in the Big Bend/Vernon areas.

Wednesday evening surface weather

The cold front extends to Detroit, Cincinnati and Memphis. Strong storms were still active in the mountains of Tennessee and Kentucky. It will be this energy in front of the front Thursday that will concern us in the mid-Atlantic.

A line of squalls will develop in the afternoon… This is where the risk of a severe storm lies.

Squall line tracking. This product has always been slow by an hour or two. So we are adjusting expectations in the morning report.

This squall line may contain the risk of severe thunderstorm cells.
