Storm will travel in the swath between the Appalachians and the Atlantic coast during Friday and Saturday.
AccuWeather Global Weather Center – December 11, 2019 – A stormy weather pattern has evolved in the eastern United States during the second week of December, and forecasters say it's likely to culminate in a significant weather system later this week.
Despite a blast of Arctic air and an episode of wintry precipitation at midweek, temperatures are forecast to quickly rebound ahead of the next major storm in most but not all areas of the East Friday and Saturday.
AccuWeather meteorologists expect a narrow zone of heavy snow to develop on the back side of the storm, but most areas can expect a dose of rain rather than snow over the eastern third of the nation.
Instead of an intense storm traveling up the spine of the Appalachians or hugging the coast with cold air nearby and heavy snow in the eastern part of the Ohio Valley, a more moderate storm will travel in the swath between the Appalachians and the Atlantic coast during Friday and Saturday. Drenching rain and localized flooding are in store for much of the Eastern seaboard. Onshore winds can lead to minor coastal flooding at times of high tide. Enough cold air will remain rooted in parts of the East to allow for some wintry precipitation and travel.
Some snow is forecast to fall on the central Great Lakes with a wintry mix for a time in northern New England. However, a more dangerous form of precipitation is forecast for a narrow zone across the interior, including parts of the South.
