Waves of wet weather on tap for Northeast in final days of November
Active weather is forecast for the northeastern U.S. for the final days of November, and AccuWeather forecasters say rain, and even some snowflakes, could be in the offing before the calendar changes to December.
Already, the weather pattern has proven to be unsettled in recent days. After dousing the lower Mississippi River Valley with thunderstorms on Saturday, much of the Eastern Seaboard was drenched on Sunday, impacting travel plans for those returning home after the Thanksgiving holiday.
Across the Mid-Atlantic and Northeast, rainfall totals often varied substantially from location to location. While Washington, D.C. only received around a quarter inch of rain on Sunday, portions of the New York City metro area saw close to an inch of rain, enough to cause meaningful travel impacts.
Following the brunt of the storm Sunday night, drier conditions are expected for Monday; however, any delayed travelers should not expect a totally dry day.
Across much of the region, temperatures on Monday will be noticeably lower. High temperatures in cities like Pittsburgh and Cleveland will be 10 degrees Fahrenheit lower Monday afternoon compared to Sunday's high temperatures.

The rush of colder air into the Northeast will help produce a few rain and snow showers across interior New England and Upstate New York, as well as some mountainous portions of Pennsylvania. These showers are likely to remain very light, but could be enough to bring a damp start to the day.
Tuesday is likely to be a rather tranquil day across the Great Lakes and Northeast with widespread afternoon temperatures in the 40s from Detroit to Boston. However, this one day of calm conditions will proceed another round of stormy weather.
"Yet another storm is forecast to sweep the East Coast during midweek, bringing another round of wet weather," said Sojda. This is the same storm that will be responsible for a possible severe weather outbreak in the Southeast, as well as a swath of snow across the Plains and Upper Midwest.

A few rumbles of thunder may accompany rain from the Ohio Valley to the Gulf Coast, while drenching rain is expected along the East Coast into Wednesday night. Depending on the exact timing of the storm, the heaviest rain could come Wednesday afternoon and evening, impacting the commute for cities like New York, Philadelphia and Washington, D.C.
"The cold air behind this next storm will likely be more potent, allowing for rain to change to snow across portions of the Great Lakes," explained Sojda. This will be exacerbated by high winds that spread from the Midwest to the Northeast on Wednesday.
While there may not be enough moisture left behind the storm for widespread snow accumulations, flakes could fly downwind of the Great Lakes from northeastern Ohio to northern New York late Wednesday or Wednesday evening.

"There is a chance, however, that cold air catches up with the back end of the rain and a brief period of accumulating snow followed by a freeze-up occurs in the central and northern Appalachians during Wednesday night," AccuWeather Senior Meteorologist Alex Sosnowski warned.
A brief stretch of dry weather could be in the offing for the remainder of the week with dry, cool conditions forecast behind the midweek storm system.
