Hot days have been hard to come by in Summer 2014, but Wednesday will be one for much of the southeastern New England region. It won’t be middle 90s hot, but more like around 90 hot, which is about the limit it seems this season. This will be accomplished with high pressure overhead and to the south in the upper levels, and to the south at the surface, also with a cold front approaching from the northwest, increasing the southwesterly air flow over the region. This front, working with moderate humidity, may trigger a few showers and thunderstorms Wednesday afternoon and evening but I do not expect them to be widespread. Favored areas for development is interior NH and MA and down to parts of RI as well. But even though the front will not be overly productive, it will send a push of cooler and less humid air in for Thursday. At about the same time, Hurricane Cristobal will be passing several hundred miles southeast of New England. The only thing we will hear from that is some increased ocean swells Friday into the holiday weekend. During this time, high pressure ridging will try to rebuild over the East Coast while another front approaches from the west northwest. It does not look like this front will have too much push to it, but should get into the region during the second half of the weekend (later Sunday and Monday). This will bring an increased chance for showers and some thunderstorms, especially by Monday. This may also linger into Tuesday as the front hangs around along with more humidity again. Though it will warm back up over the weekend proper (Saturday-Sunday), do not expect too much heat. It should cool back slightly Monday-Tuesday.
