Thanks to today’s rain, the heatwave is history and very shortly the humidity will be too. A coldfront is sliding through the region this evening…there is still a bit of juice out there to bubble up on more heavy downpour before the evening is through in Eastern MA. But by midnight the front will have cleared all locals and comfy air will come flowing in behind it. By morning, we are looking at temps in the 50s and dewpoints in the 40s…very nice!
High pressure will settle in for the middle of the week providing ample sunshine and daily high temps in the 70s along with refreshing land and seabreezes. That same high will slide off to the east and muggy air will begin returning on Thursday. A warmfront will be draped to our north so any showers will be focused there but we’ll certainly see more clouds by Thursday.
Friday and heading into the weekend get more interesting. All eyes will be focused on the Florida Straights and the Eastern Gulf where a cluster of showers and thunderstorms may develop into our first tropical system of the season. The National Hurricane Center gives it a 20% chance of becoming “Andrea”. If it forms it is never expected to become strong but it will be loaded with moisture and with a trough digging into the East Coast, a heavy rain threat exists up and down the Eastern Seaboard late this week and into the start of the weekend. As of now, whatever forms or doesn’t form is likely to produce heavy rain Friday into Saturday with improving weather for Sunday.
