They are supposed to hit here in DC tonight/tomorrow.

Derecho is unlikely to make it past Ohio. The CAPE will be high but not that high (2500 versus 5000 last year). The 850 temperatures over the area (WV mountains into DC will be 18-20C) Last year's derecho they were 24. That's most important over the mountains because without a good supply of warm air aloft the mountains will tear the storm up.
