Couple of thoughts as we begin to close in on this event:
1.) I'm looking at the evolution of this event today across the south for timing, location of the warm front and low. If we see things are staying further south or rushing along quicker than we could expect a more muted event here tomorrow.
2.) For tomorrow, the satellite and surface obs will be key. If we somehow wind up socked in with east or northeast winds and 55 degrees at 10:00 or 11:00 am then we're probably going to bust.
3.) I would argue the ceiling on this event is pretty high, at least for this area. When even the GFS and Euro are pushing close to 1,200 SBCAPE up towards BWI then there's definitely some strong stuff at work and this isn't a case of the NAM et al being silly.
