and northern/central Plains due to strong winds and low humidity...

...Moderate to Heavy mountain snow expected in the Cascades,
northern/central Rockies, and Sierra Nevada...

...Above normal temperatures continue in the eastern U.S. through Monday...

...Below normal temperatures in the western U.S. and above normal
temperatures in the central U.S. expected by mid-week...

Two low pressure systems are tracking across southern Canada, each with a
trailing cold front draped across the continental U.S. The leading system
is just north of the Great Lakes region and will move north-northeast away
from the region today. The trailing cold front associated with this system
has been gradually weakening as it approaches the eastern U.S. and is
expected to stall along the Appalachian mountains by this afternoon.
Scattered showers and thunderstorms are expected ahead of and along the
frontal boundary today. Southerly flow ahead of the front and high
pressure ridging extending along the east coast will support the
continuation of above normal temperatures today and Monday.

The second low pressure system will move east across southern Canada and
push a dry cold front across the central U.S. today and eastern U.S.
Monday. Behind the cold front, high pressure will build and cold, dry air
will filter in from the north. The pressure gradient will tighten over the
northern/central Plains and Upper Midwest between the low pressure center
and developing high pressure, and strong winds will develop across the
region. Wind Advisories and High Wind Warning are in effect through this
evening. Strong winds and low humidity will also result in increased fire
danger, and the Storm Prediction Center has highlighted Elevated fire
weather conditions today and Monday across portions of South Dakota east
into the Minnesota River Valley and south into northeastern Iowa and
northern Nebraska. Widespread Red Flag Warnings and Fire Weather Watches
are in effect. Cooler air will shift eastwards as the front progresses,
and temperatures across the eastern U.S. will return to near normal on
Tuesday.

In the West, a cold front will continue to move south today and another
cold front will move southeast across the region Monday and Tuesday. These
two systems will produce widespread winter weather at mid and high
elevations, and moderate to heavy mountain snow is expected in portions of
the Cascades, northern/central Rockies, and Sierra Nevada mountains. As a
result, Winter Weather Advisories and Winter Storm Warnings are in effect.
Cold air will spread south across the West behind the frontal systems, and
temperatures will trend downwards through mid-week. High temperatures will
drop to 15-20 degrees below normal in some areas. While the West cools
down, the central U.S. will begin to warm as southerly flow develops
mid-week.
