Just want to say that SPC has really upped their game in recent years. They were already solid, but man when they issue a Tornado Watch does it verify solidly in these parts.
Eventually went to 8 alarms. Fire jumped several roads with flame heights in excess of 300 feet. Maryland and PA National Guard air assets got water for target air drops. Over 700 acres before containment. Some real west coast stuff.
Looks like we have a broad SW flow at the surface and aloft, so I don't think we're going to have to worry too much about a river wind. But hey, it's DCA.
If the HRRR is to be believed, it's possible that DCA and Cumberland could top into the upper 80s or even get a cheap 90 degree reading. DCA, because it's DCA. Cumberland, because of downsloping.
