Typical autumn weather has settled into the Northeast, but a more powerful blast of cool air is on the way.
An area of high pressure will move into the region this weekend, kicking away the Subtropical Storm Melissa that brought rain, coastal flooding and gusty winds to the Northeast coast.
This will ensure dry weather for the Northeast for most of the weekend.
What is left of the blizzard that buried parts of the northern Plains this week will stall just north of the Great Lakes, bringing a slight dip in temperatures for some interior parts of the Northeast during the weekend.
Along the Interstate 95 corridor, temperatures will hold at the mid-October normals, not wavering until the arrival of a storm during the middle of the week.
A storm that will dive down from Canada early next week will move through the Great Lakes and into the Northeast by Wednesday.
The storm will deliver showers and periods of rain from northern New England to the mid-Atlantic. It will also draw tropical moisture from a rain-maker moving through the southeastern United States at the same time.
The more tropical moisture the storm draws northward, the more widespread heavy downpours and the flash flooding threat will be in the Northeast.
A new air mass will follow behind this storm, bringing windy and chilly conditions to much of the Northeast at the end of next week.
After climbing into the upper 60s and lower 70s for highs on Monday, temperatures will gradually drop, bottoming out in the upper 40s and lower 50s Thursday.
"Exactly how cold it will be across the Northeast will be influenced by Typhoon Hagibis in the western Pacific Ocean," said AccuWeather Meteorologist Tyler Roys.
Overnight lows will dive down to below-normal levels, into the 30s and lower 40s.

Locations from Philadelphia on south and east could be looking at turning on their heat for just the first or second time so far this season.
Temperatures across the higher elevations of New England and the northern Appalachians will dip below freezing.
Even in the valleys, temperatures will be low enough for a killing frost or freeze in much of New England and New York.
"Residents in the mid-Atlantic should also watch for a possible freeze," Roys added.
The chilly air will slowly move out of the region next weekend with a warming trend likely for the end of October.
