DAYS 1-5 (OCTOBER 9-13)
Another warm surge is on the way, coming in behind a warm frontal passage this morning and lasting through Wednesday. But quick changes will follow this as our warm-up is attacked from 2 directions, the first being the friendly warm front which will have turned around and sneaked back as a a back-door cold front that slips in via the Gulf of Maine late Wednesday night into early Thursday, bringing a rather quick temperature drop. While this cool air invades the region from northeast to southwest at the surface, the warm and humid air will continue to flow just over that and another cold front will be approaching from the northwest, which itself would bring numerous showers, though these will be somewhat enhanced due to an infusion of moisture from Michael, a land-falling hurricane Wednesday on the Florida Panhandle, weakening to a tropical storm as it passes across Georgia and the Carolinas through Thursday. The front that came through as a back-door cold front will likely return back to the northeast as a warm front yet again Thursday night, just ahead of the cold front from the northwest, which will finally start pushing everything out of here as the center of Michael’s remains passes south of New England early Friday during its transition to an ordinary low pressure area. The passage of this low may be close enough to hold some rainfall in near the South Coast for a portion of Friday morning before a drying trend overtakes the entire region. Friday itself will still be somewhat mild as we’ll have to wait for a secondary cold front to deliver much cooler air by the start of the weekend as it passes by early Saturday. Forecast details…

DAYS 6-10 (OCTOBER 14-18)
Chilly and bright start and milder and filtered sun finish to October 14. Moisture from former Pacific Hurricane Sergio, in the form of a low pressure area passing northwest of the region with a trailing cold front, brings a chance of showers sometime during October 15 to early October 16. The remainder of this period looks generally dry with below normal temperatures.
DAYS 11-15 (OCTOBER 19-23)
Trend for this period is mostly dry weather other than a minor rain shower threat from a frontal passage around mid period, and near to below normal temperatures dominating.
