RUMORS ARE TRUE: COOL SHOT OF AIR POSSIBLE IN ABOUT A WEEK… There is high confidence in multiple model scenarios that our first real shot of cooler air may happen approximately one week from now in the September 7-9 timeframe. While this idea is far from certain, some continental air from Canada may actually reach the northern Gulf Coast and bring our overnight lows down into the 60s and perhaps even upper-50s. The map attached is one model scenario off the Global Forecast System (GFS) showing the projected overnight lows for Wednesday, September 9. Note that this IS beyond our “normal cutoff” of 7 days out, but I do feel confident enough publicly mentioning this possibility because of the strong signal in the models.
TROPICAL DEPRESSION 15 FORMS… The National Hurricane Center kicked off advisories earlier this evening on Tropical Depression 15, located east of the South Carolina coast in the western Atlantic Ocean. TD15 will likely become a tropical storm either later tonight or on Tuesday. No major land impacts are expected and TD15 will continue its trek into the open waters of the north Atlantic, really only being a concern to shipping interests.
TROPICAL WAVE IN CARIBBEAN… NHC continues to suggest this evening that a tropical wave in the Caribbean Sea has a 80% chance of becoming a tropical storm as it continues moving west or west-northwest toward the Yucatan Peninsula. We note that model guidance continues to suggest (regardless of development) that this system will likely move west toward the Bay of Campeche and potentially mainland Mexico this weekend. It is still a bit too early in the development process of this storm to give a complete all clear for our local area, but I am encouraged by the trends. We’ll keep watching and bring you the latest in the RedZone Weather app.
