On Monday, drenching rain will roll quickly across the Northeast and will mark the end of the string of days with record-challenging warmth.
Monday will be the last day with widespread 60-degree-Fahrenheit temperatures or higher for a while.
A storm will affect the central United States with severe weather, rain, snow and gusty winds this weekend. A front spiraling out from the storm will swing through the Northeast on Monday into Monday night.
While the system will lose a great deal of its punch by Monday, most locations from Virginia to upstate New York and southern Ontario can expect 6-12 hours of rain.
According to AccuWeather Chief Meteorologist Elliot Abrams, "This will seem more like a storm in the spring, rather than December."
A stiff wind and unusual warmth will accompany the rain. As a result, there will be no snow or ice for travelers to contend with.
The combination of rain, wind and patchy fog will still make for miserable travel. Motorists will need to slow down and allow for extra time during their commute. Airline delays are possible due to locally gusty winds and low cloud ceiling
"The rain will be locally heavy and could come down hard enough to cause ponding on area roadways and lead to poor drainage area flooding," AccuWeather Meteorologist Brian Thompson said. "Many locations will receive 0.50 to 1.00 inch of rain in the span of a few hours."
The rain is likely to affect the swath from Roanoke, Virginia, to Pittsburgh, Cleveland, Detroit and Buffalo, New York, much of the day.
Farther to the east, areas from Richmond, Virginia, to Washington, D.C., Philadelphia, New York City and Albany, New York, can expect the bulk of the rain to fall during the afternoon and evening hours on Monday.
In much of New England, the heaviest and steadiest rain is likely during Monday night.
By Tuesday, temperatures will be slashed by 10-15 degrees in most locations.
Highs will be in the upper 40s in the mountains and the 50s elsewhere on Tuesday. Temperatures at this level are still 10-15 degrees above average for the middle of December.
High temperatures for much of the balance of next week will be similar to Tuesday east of the Appalachians.
There is a chance it may get chilly enough for a period of wet snow or a wintry mix in parts of the central and northern Appalachians toward the end of next week. Whether or not there is any freezing or frozen precipitation is contingent on the magnitude of the chill and the track of a southern storm.
The potential exists for another warm surge during the week of Christmas.
