Severe Thunderstorm Watch Expanded To Maryland And Delaware

Tuesday August 25 2020

A cold front will ignite a line of storms this evening. It has been developing in central PA this afternoon and will drop south into Maryland through this evening. This will be a fast moving line capable of producing storms with dangerous lightning, flash flooding, large hail, and isolated tornadoes.

Doppler Radar shown here appears to have the line of storms nearly 2 hours faster than the model forecast timeline. Consider that in the arrival for your area.

Severe Thunderstorm Watch:

The National Weather Service has issued this ‘Watch’ until 9 PM for much Pennsylvania as I noted in my last report.

This has finally officially been expanded south to include Maryland and Delaware through 11 PM. Please see the radar simulation timeline below for a better idea.

Warning Note: A Warning will be issued when a storm producing severe weather conditions is actually happening.

Here we can see the first sign of the storms developing along that cold front.

Radar Snapshot

Storms have been very active in mountains of western Pennsylvania already.

This is 2 HOURS AHEAD OF THE NAM 3 KM Model Below

Radar Simulation—> slider

Based on the radar snapshot above, consider the timeline below 1 to 2 hours ahead of schedule.

That could bring the line of severe storms into metro Baltimore between 6 ad 8 PM, but allow a window through 10 PM for more activity in the metro area, a little later to the south and the beaches.

Remember The Severe Risk Outlook:

This was the morning outlook that showed the highest potential was in central Maryland and Delmarva
