...Well-above normal to record-breaking temperatures to continue through
the weekend across the western U.S. and southern Plains...

...Winter-like temperatures and snow expected from the Great Lakes to the
central Appalachians...

A strong upper level ridge will remain in place across the western U.S.,
supporting well-above normal to record breaking heat across much of the
western U.S. and southern Great Plains through the weekend.  Daytime highs
are expected to climb up to 10-20 degrees above normal, approaching
records highs, across many locations on both Saturday and Sunday.  Then by
late Sunday, low pressure approaching the California coast will help to
moderate temperatures and bring some much needed precipitation along the
West Coast.

In contrast to the western U.S., much colder temperatures are expected to
spread across the Midwest and the eastern U.S. this weekend.  In addition
to the colder air, a series of cold fronts will being a chance for showers
as they move across the Midwest into the Mid-Atlantic and Northeast
through the weekend.  From the Upper Midwest to the central Appalachians,
daytime temperatures will remain 10-20 degrees below normal across many
locations of Saturday, before spreading farther east into the Mid Atlantic
on Sunday.  A strong upper disturbance associated with one of these fronts
is expected to produce a good chance for snow and the potential for
significant accumulations along the Allegheny mountains from southwestern
Pennsylvania to West Virginia tomorrow .  Meanwhile, cold northwesterly
winds blowing across the northern Great Lakes will encourage lake effect
snow showers, with at least a few inches of snow possible across portions
of the U.P. and northern Lower Michigan by early tomorrow.  Lake enhanced
snow showers are expected to develop downwind of the lower Great Lakes
late tomorrow and continue into early Sunday, with locally heavy
accumulations possible from northeastern Ohio to western New York and the
Tug Hill region.
