Wednesday August 18 2021

This afternoon the core of what was once Tropical Storm Fred is in western Pennsylvania near Pittsburgh. The large mid level circulation has spread rain and storms across the Mid Atlantic to New England.

The wind flow in our region is from the Southeast, across the Chesapeake Bay, which can enhance the storm risk across Maryland.




Currently there is a Tornado Watch and Flash Flood Watch includes along the Chesapeake Bay north into Pennsylvania.

Below is a look at the latest maps, satellite, and compare the radar simulation to the live radar and lightning. 


Satellite Loop

The comma shape shows the core in western PA, but the feeder bands from the south along the Chesapeake Bay have the heat to incite severe storm formation for a few more hours.



Afternoon Wind Flow

The Circulation the flows into the central core… From the South-Southeast. This is the optimal wind to enhance severe storms in our region.



Risk Of Severe Weather

Tornado Watch

This is for the potential, not a promise. If a tornado forms, a Warning will be issued and that is when to take cover. 



Significant Tornado Parameter 

4 PM to 10 PM

The prime threat will be in southern Pennsylvania, but may include northern Maryland and parts of metro Baltimore through this evening.



Severe Storm Outlook



Flash Flood Watch

Locally heavy rain may top rates of 1 inch per hour. Local totals could be between 2 to 4 inches.

If a Severe Thunderstorm is identified, a Warning will be issued. This may be for winds over 60 mph and or extremely heavy rain with flash flooding.
