Second storm still ongoing and snow will fall from the eastern Great Lakes region and the northern Appalachians to central new England with a zone of heavy ice just south of the snow area through much of Tuesday.
AccuWeather Global Weather Center – December 17, 2019 – The second part of a double-barreled storm will spread snow, ice and drenching rain across the northeastern United States into Tuesday evening.
The first part of the storm brought snow and ice which disrupted travel, sporting events and holiday shopping over the central Plains on Sunday.
The same storm raced through the Ohio Valley and into parts of the central Appalachians and mid-Atlantic Sunday night. Much of the precipitation from that first storm fell apart during the day Monday in the mid-Atlantic.
From both systems combined, some locales in northern and central portions of Missouri into central Illinois have ended up with around a foot of snow.
Meanwhile, the second storm is still ongoing and snow will fall from the eastern Great Lakes region and the northern Appalachians to central new England with a zone of heavy ice just south of the snow area through much of Tuesday.
This second storm will bring more substantial snow and ice to much of the Northeast that escaped the worst from the first storm. The second storm has also triggered severe thunderstorms including multiple tornadoes over parts of the South.
While the threat for snow and ice has ended over the lower part of the mid-Atlantic for the duration of the storm, several inches of snow are forecast from western and central New York state to central New England through the day on Tuesday. For a time the snow can fall at the rate of 1-2 inches per hour, which can quickly cover roads and snarl traffic. This includes portions of Interstates 81, 86, 87, 88, 90 and 91.
