Sunday will be sunny and warm, but the heat and humidity will ramp up by the middle of the week.
A warm front will transport a more humid air mass into the Northeast on Tuesday, followed by typical hot humid conditions Wednesday and Thursday. The good news is the humidity will not last long, as yet another cold front will move through southern New England with a band of showers and thunderstorms late Thursday into early Friday.
There is some uncertainty on how fast the cold front will move offshore to allow for sunshine to return with clearing skies, low humidity and comfortable temperatures by the Fourth of July on Friday. For now, expect showers to end in the morning, followed by clearing afternoon skies and gradually turning less humid.
