I was just about to post that NWS warning... by my eye a strong derecho is about to move through the area in 15 minutes (west side Washington). Motion of the line is east at about 60 mph. The radar presentation shows a strong bow echo.

That's correct. The largest markets are often harder to get coverage for since they don't put as much into weather relatively speaking.

Re: June 4-7: Mid-Atlantic derecho, Plains tornadoes?
I was looking at D.C cams and it looks like many on the west side are out (power out). I don't see any signs of really high winds, looked like about 60 mph from some of the cams and no obvious debris on the streets. Perhaps lightning strikes caused the outage, or high winds elsewhere.
