We have a pair of weather systems moving our way for the beginning of August. The first of these is an area of low pressure that was bringing rain to southeastern Massachusetts Tuesday afternoon. The low is expected to track into the Gulf of Maine tonight bringing a round of precipitation to southern locations after midnight. The rain should pretty much be out of here by Wednesday morning and as the low tracks off to the northeast I expect sunshine to develop. A frontal system will then follow the low and as it approaches in the afternoon scattered showers or thunderstorms are going to break out. Most of these should be confined to New Hampshire and the western Maine mountains. The activity will die down Wednesday evening but may fire up again on Thursday as an upper air disturbance approaches our region. Warmer and more humid air is going to to arrive here on Friday as yet another cold front drops down from Canada. The front is expected to stall to our north keeping us in a very warm and muggy air mass for the upcoming weekend.
