.LONG TERM /WEDNESDAY THROUGH MONDAY/... 

With a large and slow moving area of high pressure centered to the 
east, heat continues to be the main concern during the long term. 
For Wednesday through Sunday, highs in the mid and upper 90s 
combined with dewpoints around 70 will produce peak apparent 
temperatures ranging from 100 to 104. Overnight lows in the 70s will 
only provide limited help. Based on those forecast model 
predictions, our office has issued a heat advisory that is in effect 
through Friday. Extending the heat advisory through next weekend 
appears strongly possible. At some point, if apparent Ts are 
forecast to go above 104, we will need to upgrade to an excessive 
heat warning. There is relief on the horizon when an upper trough 
and cold front bring an end to the extreme heat next Monday, with 
highs retreating to the mid and upper 80s. 

Chances for abatement from the heat due to precip appear to be 
low. There is a chance for a few thunderstorms on Wednesday, and 
again on Sunday ahead of the cold front. A better chance for 
measurable precip will be on Sunday night and Monday surrounding the 
cold frontal passage.
