We have to wait for the stuff back in WV.  The 2nd round was always 7pm-ish.

The thinking is more linear as it moves eastward towards the coast, and reading the discussion from Mount Holly they think the most likely place for a tornado is in Cecil over into Newcastle in DE up into SE PA. Possibly some interaction with the warm front lying across that area, backing the flow some is my guess. Bigger overall  threat will be damaging straight line winds, with fairly strong winds aloft and decent Dcape. Bowing segments generally produce straight line winds but can also produce tornadoes as vorticity sometimes develops on the north/south end of the line. How far north are you?

Thank you for such a detailed response :) I’m in northeastern Kent County! My parents grew up in Newark and always talked about the intense thunderstorms they would get.

New Castle had a lot of tornado damage from Isaias. Hoping they don’t see too much damage from today

My concern would be this first round being close enough to steal all the juice in the air

Is that stuff doing something near Sykesville?

 

No, carroll/howard CAD is quiet.

It isn't really putting out the outflow boundaries that we see sometimes.  Check out the clear air returns on radar.  All our air is still coming from the S.

What about the cell near Eldersburg.  

Just got an SVR. The reflectivity looks nice but man the velocities are pitiful.
