The pattern for later this month and October seems to favor warmer periods and then cooler airmasses and then back to warm again, cycling through the month.
As mentioned by @WxUSAF early part of October looks to have a rather large cool down over the NE and Mid Atlantic.

The early - mid October pattern looks to feature more frequent shots of colder air across the Eastern US. While we have another warm up next week, keep a close eye on the potential for the coolest air of the season arriving behind stronger fronts ~October 3 - 5th and October 7 - 9th.
