...Rain and snow for the southwest U.S., and another winter storm for New
England by Sunday night...
A zonal flow pattern at the beginning of the period will transition to a
more amplified pattern by Sunday night, with a sharp trough over the
northeast U.S. and an upper level low over northwestern Mexico. An upper
level ridge will become established over the West Coast.
After a brief cold snap for the East Coast, a warming trend is arriving in
time for the weekend courtesy of a warm front. It will continue to stay
quite cold across northern New England, which will remain north of the
frontal boundary. By Sunday night, another nor'easter is forecast to
develop rapidly just off the New England Coast and will likely cause
significant wind and snow impacts from upstate New York to Maine, and
winter storm watches are already in effect. Showers and a few storms will
be possible from the Deep South to the Ohio Valley this weekend as
moisture from the Gulf of Mexico is advected northward around the
departing surface high pressure, and ahead of a strong cold front. Given
the lack of sufficient wind shear or instability, no severe weather is
anticipated over the next few days.
Across the western U.S., a cold front moving across the southern Rockies
will keep valley rain and mountain snow in the forecast through Saturday
evening. The upper low just south of Arizona will keep the weather
unsettled through the entire weekend, with up to an inch of rain possible
across parts of Arizona and New Mexico. Drier weather will be the rule
for the West Coast with high pressure building in with sunny to partly
cloudy skies
