Thursday September 10 2020

This tropical like system we are dealing with today has flared up bands of heavy rain. Some appear to be training from south to north, running over the same areas. There is potential for 1 to 3 inches of rain along the path, which has prompted the expansion of the Flash Flood Watch until 8 PM and 11 PM in Pennsylvania.

This now includes western Howard and Carroll Counties in Maryland. This has also been expanded north into southern Pennsylvania to include Adams, York, and Lancaster Counties.

Flash Flood Watch

This is for the ‘potential’ not promise of flooding.

Reminder: Areal Flood Advisories and Warnings will be issued when flooding is actually occurring.

September 10 Flash Flood Watch Expanded Thursday


Satellite Loop

A lot of tropical moisture has developed with widespread storms along the Mid Atlantic this afternoon.



Radar Snapshot

The heaviest rain has been in and around Washington, DC. There has also been a band over northern Carroll County into York PA. The flow has been along the same path, so flooding is possible for some while others may not get much.

Computer Model Simulation

The short range modeling has not been very accurate, which is why I do not want to showcase this. But I know you might want to see this just in case.

Note: The actual rain has been west of where the HRRR Model has plotted at 2 PM.  Consider that with the rest of the slider, but the timing of the activity may be the most valuable asset here.
