Oh dear. I am ready to begin the severe weather day.... hail to 2.5 inches? Isn't that the size of baseballs? or is that golf balls?

Matt, what state do you reside?

Take care!

Eric

I live in VA, just outside of DC... in Fairfax County..

golf balls!

i live about 50 mi from that watch, downstream watching here in eastern mass. last night there were a few storms but mostly just vivid lightning and heavy rains.

this time maybe the real deal?

capes 1500+ mostly 60kt 500mb 350+ helicity -things could really fire just north ofNYC as well! watch out poughkeepsie to western mass next couple hours..btw last few scans of the radar appeared to have a bit of rotation on one of those southern cells along the line

I'm in this watch...again, not impressed w/ radar at this time. Watch expires at 4PM, although I wouldn't be surprised to see them take it down very soon.

The radar can go from clear to full of convection in a matter of minutes.

Another watch is out!
