...Turning colder across much of the nation with a couple storm systems
having snow potential...
A major weather pattern change is in the works across the nation as an
upper level ridge builds over the western U.S. and a deep trough becomes
entrenched across the East. Sprawling high pressure over Canada will
continue oozing southward across much of the central and eastern U.S.
through the weekend, bringing much colder temperatures that are more
typical of January to locations east of the Rockies. Expect temperatures
to drop on the order of 15 to 30 degrees compared to readings observed on
Wednesday and Thursday with the passage of an arctic front.
Surface cyclogenesis is forecast to develop along this front on Friday
near the New England coast and become a powerful nor'easter as it lifts
northward across the Canadian Maritimes by Saturday. Accumulating snow is
expected from Pennsylvania to southern New England with this system, with
some locations receiving close to six inches of snow east of New York
City. Another disturbance crossing the Plains and towards the Gulf of
Mexico over the weekend will bring rain and thunderstorms back to the
southern Plains and Deep South, and snow from the Midwest to Tennessee.
Elsewhere across the continental U.S., expect dry and pleasant conditions
for the southwestern U.S. where upper level ridging will persist. Very
cold conditions will continue across the northern Plains and Upper Midwest
with a few snow showers possible, and some lake effect snow is also likely
downwind of the Great Lakes given the strong cold air advection.
