The humid stretch of weather continues, but rainfall was limited during the weekend as most of the moisture was going around the edge of a high pressure area over the western Atlantic, and staying offshore of New England. This will continue to be the case early this week, also aided by a high pressure area at the surface, building down from the Canadian Maritimes. This means mostly dry weather through Tuesday, lots of clouds at times but sun as well, and air still somewhat humid but not oppressively so. As we get to the middle of the week, the rain chances will increase as a cut-off low pressure area to the west moves westward and the ridge to the east also nudges westward, pushing the area of moisture back to the west as well. This low to the west is finally expected to shift northeastward, combine with another trough, and swing through New England at the end of the week, first with additional showers, then opening the door for some drier and cooler air by weekend, which is also the start of October! It should be noted that some of the computer guidance slows this trough down as it comes by here, and even tries to close it off, or cut it off from the main jet stream, allowing it to sit over or just east of New England next weekend. This scenario would be more unsettled than what I have in my extended forecast, but I consider it only a slight possibility at this time, hence the more optimistic forecast. Stay tuned for later updates…
