The National Hurricane Center has initiated advisories on Potential Tropical Cyclone (PTC) 9 this evening. The area of organizing thunderstorms is located in the Bahamas, and is expected to drift northwestward over the next day or so while continuing to organize.
Warmth and humidity will stick around for another day, with showers and thunderstorms also likely this afternoon and evening. You can thank a slow moving front boundary for that. It will meander in New England today, finally dropping southward this evening.
A large ridge of high pressure is expected to build over the Central and Eastern United States late this week, with temperatures rising several degrees above normal. Most forecast models agree that this ridge will have staying power, hanging around for at least 7-10 days.
