A shortwave trough moving over New England will trigger showers and isolated thunderstorms through late this evening.
Not everyone will see rain, these downpours will be hit or miss and the best chance during the evening will be across western zones. Looking at all of our data, the parameters just aren't there for damaging winds or severe weather. However, locally heavy downpours that move slowly could cause some brief poor drainage street flooding.
Tonight showers and thunderstorms will diminish some, and low clouds and patchy fog will temporarily take their place. During the pre-dawn hours, however, showers will likely re-develop. Unsettled weather continues on Wednesday as a cold front triggers another round of showers and thunderstorms - this time widespread.
The front will drop from Canada to the north country during the morning hours, then towards southern New England during the afternoon. Severe weather potential Wednesday again looks rather low due to marginal instability.
Heavy downpours will once again be the main concern.
Very humid Wednesday with highs mainly in the 70s to about 80 degrees. Thursday and Friday are looking really good as high pressure builds over the area and brings a less humid, drier, cooler air mass to New England.
