The cold front that has been responsible for all the rain the last two days is now moving through southern portions of the viewing area. It will slide south of us overnight, taking the rain and most of the cloud cover with it. Cooler and drier air filters in behind the front where highs will only rebound to the mid 80s tomorrow and lows will remain in the 60s for the first time since early July.
The cooler and drier air will remain in place into the weekend and only a stray shower is possible Thursday into next week.
Our concern, however, now focuses on the western Caribbean where a tropical wave looks to be developing into at least a tropical depression. If this system becomes a tropical storm, it will become Erin, the fifth named storm of the season. This wave is forecast to become a tropical storm in the next 2 to 3 days, and most models forecast this storm at this point to head for the central Gulf Coast (Mississippi/Alabama/Louisiana). If this path is followed, it will mean tropical rains for us and other impacts from a landfalling tropical system. We will be monitoring this system very closely, and you should too, especially if you have plans to head to the coast this weekend.
