As the holidays approach and many may find themselves dreaming of a white Christmas, Mother Nature has a different idea up her sleeves. The weather pattern will soon be reversed in the northeastern United States, allowing wintry landscapes to transform into a sloppy, muddy mess instead.Forecasters are closely watching a storm system that is expected to take shape and track toward the Great Lakes early next week — and it will be the player that will help to flip the weather conditions in the East. As wintry weather and yet another snowstorm are predicted for portions of the Midwest, surging warm and moist air will race out ahead of the system.Temperatures are expected to rebound to the 30s over the northern tier to near 50 F in parts of Virginia as a southerly breeze develops on Sunday.On Monday, temperatures are forecast to surge into the 40s across the northern tier and the 50s and 60s across part of the mid-Atlantic region. The warm air combined with rain will dissolve the deep snow over part of the Northeast, potentially leading to flooding issues for some communities. Recent storms have buried parts of New York state and central and northern New England under as much as 1-3 feet of snow in the last couple of weeks.

(NOAA) Some of the deep snow may harmlessly melt from Sunday to early Monday before the storm and its soaking rain arrives, but there is a risk that surging temperatures, moist air and drenching rain may cause a rapid meltdown of the existing snowcover from later Monday into Tuesday.Instead of releasing the 1-5 inches of water by itself, another 1-2 inches of water may be added in depending on the intensity of the rainfall that occurs. "Since the ground is not frozen, some of the melting snow and rain will be absorbed by the soil and should avoid disastrous stream and river flooding," Dale Mohler, AccuWeather senior meteorologist, said.However, some quick rises on small streams are likely with minor flooding possible in low-lying areas that are prone to flooding during heavy rain or spring thaw events. Some of the rivers may surge to bank full as well."Even if only part of the snow melts and only a light amount of rain falls, piles of snow along streets and highways that are blocking storm drains can lead to urban flooding," Brett Anderson, AccuWeather senior meteorologist, said.Anderson said that property owners should make sure that runoff has easy access to storm drains ahead of the system's arrival to reduce the risk of flooding as a precaution."Even in some of the major cities along the Interstate 95 corridor from Washington, D.C., to Philadelphia and New York City where there is no appreciable snow on the ground, enough rain can fall to cause travel delays and ponding on roads that drain poorly," Dave Bowers, AccuWeather forecaster, said.Ski resorts in the region that have gotten off to their earliest start in recent years will take a hit from the storm. Those seeking ideal ski conditions are encouraged to hit the slopes into Sunday, before the rainstorm arrives.Along with bringing a swath of heavy snow to part of the Upper Midwest, next week's storm is predicted to unleash Arctic air in its wake later Tuesday and Wednesday. Remaining areas of slush and standing water can freeze as temperatures plummet across the northeastern U.S. There is a chance that the cold air may catch up with the back end of the rain and cause a period of snow at the tail end of the storm at midweek.Since the storm will be weak rather than strong, it's possible that a secondary storm may develop along the push of frigid air, according to AccuWeather Chief Broadcast Meteorologist Bernie Rayno."I am pretty convinced that a storm is going to form along this boundary [between warmer air in place and colder air surging] into the Carolinas Tuesday night. Then, the question becomes does the storm goes out to sea and the cold front blasts out to sea? Or, does the storm have enough energy because of all of the energy associated with the jet stream that the storm strengthens? And, if it does, it won't go out to sea. It will come up the coast. If the storm does strengthen, you've got to worry about a snowstorm," Rayno said.The I-95 corridor of the mid-Atlantic and eastern New England could face snow if the latter and stronger scenario unfolds. If a weaker secondary storm develops, then it will likely push out to sea. If a secondary storm forms and it strengthens enough, it may bring snow to the Northeast. No indications are currently pointing to a big snowstorm developing and rather it could be more of a nuisance snowfall, according to Rayno.However, this type of weather pattern has yielded major snowstorms in the past, and meteorologists will have to keep a watchful eye on how all of the weather players come together, Rayno added.AccuWeather meteorologists are also tracking the potential for yet another significant storm toward the middle of the month, warning that it could be disruptive to the eastern U.S. Download the free AccuWeather app to check the forecast in your area.
