Parts of the Northeast will be in for a wet day while other towns experience a round or two of showers and thunderstorms. Either way, many towns will receive a much-needed rain because rainfall year-to-date is below average across much of the Mid-Atlantic and New England. With tropical moisture flowing in from the south ahead of a warm front, that will promote the risk for heavy rain.
This morning, other than a few spotty showers, the Mid-Atlantic is dry. Most of the action is in New England with a large area of heavy rain and thunderstorms moving eastward across most of the region with the exception of northern Maine. There may be a severe component with this morning’s storms as strong wind shear moves into southern New England. If some of these storms were to rotate, there is the very small chance they produce damaging winds and a spin-up tornado. Due to the limited instability, however, we are not to worried about this risk.
Then into the afternoon, the rain and thunderstorms will become a bit more scattered but will continue to bring rain to much of eastern New England for most of the remainder of the day, especially in eastern and northern parts of Maine. This will make out for a Thursday washout in these areas. Meanwhile back to the west, a line of widely scattered thunderstorms will track eastward across the northern Mid-Atlantic and western New England. Some of these storms will contain gusty winds but we aren’t concerned about any severe weather by this point in time. Once the storms reach eastern New England, they will weaken and eventually dissipate due to the lack of solar energy. This is due to the cold front arriving after sunset.
Rainfall will be heavy with many towns likely receiving over an inch of rain across New England. Some towns will receive more than 2 inches while others receive less then an inch. The weather will then improve beginning Friday, but it will turn very hot for an extended period.
