An area of low pressure spinning in the northern Gulf of Mexico will
steadily lift through the Southeast Friday night...before rapidly
deepening while tracking up the Eastern Seaboard on Saturday. An
abundance of Gulf and Atlantic moisture being pulled into the
strengthening storm will fuel widespread precipitation across the eastern
third of the Nation. Heavy rains and thunderstorms are expected over the
Southeast and southern Mid-Atlantic states...and a swath of accumulating
snow is expected from the central Appalachians to southern New England.
Marginal temperatures surrounding the I-95 corridor will lead to a messy
transition zone of sleet and freezing rain between the heavy rain and snow.
Light snows will be possible with a cold front sweeping from the Upper
Great Lakes to interior New England on Saturday. Upstream...a clipper
system dropping down from Canada will streak snows across the Upper
Midwest while it slides from the northern Plains to the Middle Mississippi
Valley Saturday into Sunday.
A series of Pacific systems moving inland will keep conditions wet across
the extreme northwestern corner of the Nation Friday night. Above normal
temperatures in the Northwest will limit any snow potential...but a ripe
slug of moisture streaming onshore should lead to heavy rains along the
upslope side of the Olympics and Cascades. Precipitation should come to
an end on Sunday as ridging builds in aloft.
