...Critical Fire Weather threat for parts of the Central Plains...

...Coastal rain and heavy mountain snow likely in the West...

...Cool down in store for northern tier and eastern half of country this
weekend...


Warm, dry and windy conditions, caused by the emergence of a strong cold
front from the Rockies will contribute to a critical fire weather threat
for parts of southeastern Colorado and southwestern Kansas this afternoon.
High Wind Warnings and Wind Advisories are in effect for much of the
Central Plains extending from southeastern Wyoming to the Texas Panhandle.
Windy conditions should let up early Saturday morning.

Showers and thunderstorms will focus along the aforementioned cold front
as it pushes east into the Midwest and East Coast through Saturday. Light
to moderate lake effect snow will develop over portions of the Upper
Peninsula of Michigan over the next couple of days as winds out of the
northwest advect over the relatively warm Lake Superior waters.

A slow moving upper-level low will direct Pacific moisture and a low
pressure system at the West Coast over the next couple of days. Coastal
rain and mountain snow will begin over the Pacific Northwest tonight and
end by tomorrow morning. The heaviest snow is likely to occur over the
Olympic mountains of Washington where between 6-12 inches are possible.
Coastal/low elevation rain and heavy mountain snow will develop over
California on Saturday as the upper low taps subtropical Pacific moisture.
Some parts of the northern and central-southern California coast may
receive between 1-3 inches of rain by Sunday night. Heavy snow picks up
over the Sierra late Saturday and into Sunday where between 2-3 feet of
snow is likely by Sunday night.

Elsewhere, warmer than normal temperatures are likely to come to an end
across the Plains tonight as the aforementioned cold front sweeps through
the region. The eastern third of the country will suffer the same fate as
the Plains on Saturday night as the cold front accelerates off into the
Western Atlantic. Rainfall activity picks up over the Southeast early next
week.
