Southwesterly winds with PW around 1.7 will continue today and tomorrow. This will result in lower rain shower chances with the highest totals inland and along the east coast. The strong southwesterly flow will result in winds coming off the warm Gulf water overnight. This will keep overnight lows near 80 degrees near the coast. This warmer start coupled with lower shower chances will result in above average temperatures and humidity. This will bring heat index near heat advisory criteria both tomorrow and Friday.

Starting on Friday we will see an increase in moisture with PWs reach around 2 inches. This will bring higher rainshower chances.
However, we will still be in southwesterly flow. This will result in much of the shower activity staying inland and along the east coast.

Drier air will start to filter in on Monday lower rain shower chances as we continue to see southwesterly flow. Flow looks to turn more neutral on Tuesday which would favor storms closer to the west coast however the drier air in place will continue to keep our shower chances low.
