The eastern half of the U.S. will have colder than average temperatures to
close out the week with an upper trough overhead and northerly winds.
Widespread 30s and 40s are expected for daytime highs, and subfreezing
lows. Some lake effect snow showers are also expected downwind of the
Great Lakes. Warmer weather is forecast to arrive for the weekend as the
cold surface high moves eastward and the wind becomes more southerly.
Across the northern Rockies and northern Plains, an arctic front slowly
sagging southward from Canada will bring much colder weather from
Washington state to the Dakotas for this weekend. A sharp drop in
temperatures is expected where this front passes through. There will also
be widespread light to occasionally moderate snow with this front, but the
greatest concentration of heavy snow should remain north of the Canadian
Elsewhere across the continental U.S., nice weather will continue from the
southwestern U.S. to the Deep South with mostly clear skies and dry
conditions. Periods of rain are likely for northern California and Oregon
with onshore flow and a cold front moving through the region.
