Lakes...

...Temperatures will be below average for large sections of the country
this holiday weekend...

A winter storm associated with an upper-level trough/surface frontal
system moving through the Central/Southern Rockies will continue today,
with snow tapering off for the Central/Southern Rockies and adjacent
portions of the High Plains while shifting deeper into the Central Plains.
An axis of moderate to heavy snowfall is forecast from southwestern to
northeastern Kansas with totals of 4-8 inches possible. Gusty winds as
well as heavy snow bands with rates of 1"/hr at times will contribute to
hazardous travel conditions. A wintry mix with additional lighter
accumulations of snow is expected from the Texas/Oklahoma panhandles
through southeastern Kansas into northern Missouri. Conditions should
clear out by Sunday morning.

Some locally heavy rainfall will be possible with thunderstorms in South
Florida Saturday, with a chance of an isolated instances or two of flash
flooding. Then, as the upper-level trough and a pair of surface frontal
systems begin to shift rapidly eastward, an area of expanding showers and
some thunderstorms is expected across the eastern U.S., starting late
Saturday/early Sunday for portions of Texas to the Lower Mississippi
Valley, eventually pushing through the Ohio Valley and Southeast towards
the East Coast by later Sunday afternoon. More moderate to heavier amounts
are most likely along the Gulf Coast and also across portions of New
England as a coastal low organizes to the southeast. A wintry mix will be
possible further north and west from the Midwest into the Appalachians and
the Interior Northeast, though any accumulations should remain limited.
However, northwesterly flow over the Great Lakes will lead to some locally
enhanced areas of moderate lake effect snowfall, particularly for
favorable areas of the Upper and Lower Peninsulas of Michigan where totals
Sunday could exceed 4".

Temperatures will generally be below average for much of the country this
weekend, with the greatest anomalies in portions of the Central and
Southern Plains. Highs on Saturday will be in the 20s and 30s for the
Central Plains and 40s into northern portions of the Southern Plains, with
morning lows Sunday dipping into the teens and 20s, leading to wind chills
in the single digits and potentially even below 0 for some location. Highs
in the 30s and 40s will be common in the Southwest with 50s and 60s in the
South. Temperatures will be well below average as well Saturday in New
England, with 20s and 30s forecast, as well as in the Mid-Atlantic, where
40s are expected. Conditions should moderate a bit Sunday. The West will
also see many areas below average, with 30s and 40s for much of the
interior and 60s to low 70s for the Desert Southwest. The West Coast will
be closer to average, with 50s and 60s, and 70s for Southern California.
However, the central California Valleys as well as northern portions of
the Mojave Desert will see lows near the freezing mark, with
freeze-related advisories in place.
