Discussion
High pressure over New England will control our weather for another day before it shifts eastward to a position off the east coast by later tonight and early Wednesday. As the high shifts to the east, our low-level winds will change direction and turn to a more southwesterly direction and overall humidity will climb. Also, as a front slides eastward towards the Mid-Atlantic region, our chances for showers and thunderstorms will rise later Wednesday and that threat should continue into Thursday as well. Heat and humidity will then build noticeably around here on Friday and uncomfortable conditions will continue this weekend and likely right into the middle of next week.
