A significant winter storm recently swept through the Northeast, causing travel chaos post-Christmas. Now, another system is on the way, bringing a mix of rain, snow, and unusually cold temperatures as we head into the new year.
Officials in New York and New Jersey declared a state of emergency as thousands of flights faced delays or cancellations on Friday.
This cold front is concerning for many, potentially leading to severe storms, flash flooding, and significant lake-effect snow accumulation.
Beginning Sunday, a low-pressure system will roll into the upper Midwest, bringing with it rain, snow, and strong winds.
As it moves east on Sunday, colder air will likely lead to snow developing from Minneapolis to Michigan.
Normally, we expect about 5 to 8 inches of snowfall, but localized lake-effect snow could bump that up to 18 inches, especially as colder air settles in over the northern Great Lakes, according to forecasts.
To the south, moisture and rapid snowmelt near the low-pressure center may create flash flood risks along Lake Michigan and Lake Erie.
Precipitation typically measures 1 to 2 inches, but the existing snow and warming temperatures could elevate flooding concerns in cities like Chicago, Cleveland, and Buffalo.
Before the front passes, rain will blanket the eastern Great Lakes. As it advances into the Tennessee Valley, stronger storms are expected.
A Level 1/5 severe storm alert is in place from northern Indiana to Missouri, covering areas including Indianapolis, St. Louis, Louisville, and Nashville.
The primary concern is high winds, though isolated tornadoes could also pose a risk due to current atmospheric conditions.
To the northeast
As the front pushes eastward on Sunday evening, rain will move into the Northeast, clearing any lingering snow. Though temperatures will mostly stay below freezing, making snow accumulation less likely in many places.
However, in areas where cold air is trapped, icing could make travel in New England, particularly in higher elevations, quite treacherous.
A winter weather warning has been issued for most of New England, with up to 0.10 inches of ice possible.
Along I-95, temperatures will likely remain warm enough for rain to dominate the weather.
Strong wind gusts are expected to develop rapidly in both the Midwest and Northeast, raising concerns about potential power outages.
As winds shift from the northwest, even colder air will lead to notable lake-effect snow, especially around Lake Erie and Lake Ontario.
Parts of western and northern New York could see considerable snowfall through Tuesday, with totals potentially surpassing a foot.
