National Weather Forecast: Hercules takes aim on the Eastern Seaboard

Winter Storm Forecast

…Organizing winter storm to impact much of the Eastern U.S….

…Arctic air set to infiltrate the Northeast in the wake of the system…

Precipitation will continue to expand and push eastward today along and
ahead of a frontal boundary draped from the Mid-Atlantic back toward the
lower Mississippi Valley. In the Gulf Mexico, another frontal boundary is
slowly lifting northward, helping to spread rain through the Southeast.
These two areas will merge off the East Coast later tonight and will
coalesce into a rapidly deepening system just southeast of New England.
With cold air in place to the north and northwest of the low center, light
to moderate snow is expected. Parts of southern New England and
eastern/southeastern NY may experience a period of heavy snow with
blustery winds as the low pressure deepens but pulls away from the coast
very early Friday, making travel difficult between New York and Boston.

To the south, the cold front will push through central and southern
Florida with little fanfare outside of some scattered showers but cooler
temperatures. Much colder air will usher into the East on Friday with many
areas 20-30 degrees below normal. Precipitation should wind down on Friday
as high pressure moves into the central Appalachians, setting up a very
cold night for many Northeast cities. Some record low temperatures are
possible.

In the Pacific Northwest, a front will move onshore later today with
rain/snow showers over the region, especially along and west of the
Cascades. On Friday the system will push eastward, spreading rain/snow
through the Bitterroots and into Wyoming. Cooler temperatures will follow
behind the front.
