Fourth of July Forecast for East Coast

The tropical moisture flow that has been ruining many plans for a while now will begin to move away. A high pressure system moving in from the coast will change the airflow, moving the "river of rain" to the west.  In the morning it should stay dry but as we go into the afternoon there is a chance for a shower and thunderstorm, but thankfully they should move away fast enough to not affect your firework show. Temperatures will be in the mid to upper 80s in the afternoon and in the mid 70s in the evening. Happy Fourth of July!
