.DISCUSSION...
Very warm and relatively breezy day is expected across the air 
show vicinity. There is a risk of strong thunderstorms late in the
afternoon as a front pushes through. A few thunderstorms could be
severe with damaging winds up to 65 mph the primary threat, along
with small hail, heavy rain and of course cloud to ground 
lightning. At this time, the best chance of storms tracking over 
the area is between 3 pm and 8 pm. Around 5-6 pm seems to be the 
peak threat period. 

RH readings may drop into the upper teens during the afternoon, 
and with the strong winds associated with the frontal passage and 
storms, we do have fire weather concerns. Anything that could cause 
a spark is concerning ahead of this wind threat. BT
