Should I take BGimple to see a tornado?. (Imagine his horror when he realized that fog is just a cloud at ground level.).
When the clouds are so fake they forget to stay in the sky.

DMV gang — watching a threat of strong to severe storms for Friday (tomorrow). Could be an isolated low-end tornado threat in southern, south central and southeastern Virginia. Otherwise brief heavy downpours are possible:

Watching for an evening tornando risk across Somerset, Piscataquis and Aroostook Counties in northern Maine. There’s enough shear (spin) and instability (juice) to support both instances of straight-line wind damage and an isolated rotating storm.

Storm is turning right — southeastward. That’s a classic step before tornadogenesis. Seek shelter NOW if in Upperco or Boring!.
Possible TORNADO in northern Maryland! If east of Westminster, seek shelter NOW! Doesn’t matter if there’s a warning or not!

DMV gang — storm with some rotation and severe wind gusts around 60 mph located near Leesburg, sagging southeast along the Potomac. I anticipate this to approach D.C. around 8:30-ish. It may get absorbed into a broader mass of torrential rains.
