...Locally heavy lake effect snowfall to continue downwind of the Great
...Critical fire weather persisting across southern California...
Relatively quiet weather will be in store for much of the country as a
winter storm continues to pull away from the Northeast Sunday morning. A
quick moving and moisture starved upper level disturbance will bring a
chance of light snow showers to the Northeast today/tonight but the
greatest snowfall accumulations will be east of lakes Erie and Ontario due
to lake effect snow where local totals up to a foot are forecast into
Heavy lake effect snow accumulations will also be possible across the
Michigan U.P. Monday night into Tuesday behind a quick moving clipper
system. This clipper is expected to drop into the north-central U.S.
tonight bringing light snow, 1 to 3 inches, to northern Minnesota and
Wisconsin by Monday afternoon.
Regarding temperatures, the East Coast will be 5-15 degrees below average
today with some moderation on Monday. Most of the Plains will be 10 to 25
degrees above average today and Monday with westerly to northwesterly
downslope winds at the surface. Winds will also be gusty at times,
especially on Monday after the passage of a cold front tied to the
aforementioned clipper system. These winds will also generate dry
conditions leading to an elevated risk for wildfires extending throughout
parts of the southern and central High Plains through Monday.
The greater risk of wildfires will be across California though, where
critical fire weather conditions will persist through at least Monday
given continued strong Santa Ana winds and low relative humidities.
