for the rest of the weekend; severe weather possible from Georgia to
Florida into Sunday...

following mixed rain and snow on Sunday...

...Elevated to critical fire weather risk remains in place for parts of
the Southwest and southern High Plains...

A low pressure system moving toward the Great Lakes will bring widespread
unsettled weather across the eastern U.S. for the rest of the weekend as a
cold upper-level trough pushes across the Northwest into the northern
Plains.  Severe weather and heavy downpours will be most likely across
southern Georgia into northern Florida through tonight well ahead of a
cold front moving into the Deep South.  Meanwhile, a swath of rain will
move across much of the Midwest into Sunday as the center of the low
pressure system passes to the southeast.  Rain and embedded strong
thunderstorms are also in the forecast from the Great Lakes and Ohio
Valley spreading into the Appalachians and the Mid-Atlantic tonight, then
into the western and southern New England ahead of a warm front.  Rain
intensity should taper off over the Great Lakes later on Sunday as the
system gradually weakens.  However, a good chance and strong to severe
thunderstorms is forecast for northern Florida on Sunday as the cold front
approaches.  Meanwhile, rain and embedded thunderstorms along the East
Coast will gradually move out to sea later on Sunday as the cold front
moves off the coast.

In the Northwest, a cold upper-level trough will continue to bring below
normal temperatures through the region as it helps the development of a
new low pressure system across the northern Plains during the next couple
of days.  Scattered mountain snows across the Pacific Northwest are
expected to move into the northern Rockies and the northern High Plains by
this evening.  Most snowfall accumulations should remain below 6 inches,
with the exceptions being in the highest elevations of the Cascades and
northern Rockies where higher amounts are possible.  On Sunday, mixed rain
and snow is expected to reach North Dakota as cold air wraps around the
developing system.  The system will attempt to merge with the weakening
low pressure system over the Great Lakes to promote wet snow across North
Dakota into northern Minnesota where up to 8 inches is possible near the
Canadian border.

Regarding other weather hazards around the country, fire weather
conditions remain at elevated to critical levels in parts of the southern
High Plains and southern Rockies tonight with slight improvement possible
on Sunday.  Elsewhere, the fire weather risk is elevated over central
Florida.
