...Moderate to heavy rain will spread from the Deep South to the entire
East Coast over the next couple of days with severe thunderstorms possible
across the Southeast and the Mid-Atlantic coast...

...Accumulating snow expected for parts of the Ohio Valley and the
central/southern Appalachians on Monday and Tuesday...

...Elevated Fire Weather Risk continues in southern California...

An area of low pressure, currently over the central Gulf coast, will go on
to be the focus for rain, thunderstorms and snow for much of the eastern
U.S. through Tuesday. Through tonight, this low pressure system is
expected to begin it's ascent from the Gulf Coast up into the Southeast,
as it continues streaming Gulf moisture into the Deep South. Rising
instability along the system's surface boundaries will give way to the
chance for severe thunderstorms. A Slight Risk of Severe Thunderstorms is
in effect for parts of the Coastal Carolinas and the central Gulf coast as
a result. This low pressure system will strengthen even more tomorrow and
Tuesday as it tracks up the spine of the Appalachian Mountains. Moderate
to heavy rainfall as well as scattered to severe thunderstorms are likely
for the entire East Coast. A Slight Risk of Severe Thunderstorms is in
effect for parts of southeastern Virginia into coastal North Carolina on
Monday where, according to the Storm Prediction Center, conditions will
favor locally damaging winds and the possibility for a couple tornadoes.

High Pressure building over the Upper Great Lakes paired with the
continued strengthening of the mid-latitude cyclone in the East will lead
to the probability for heavy snow over parts of the Ohio Valley and
Central Appalachians on Monday and Tuesday. A trailing cold front is
forecast to sweep through the Midwest tomorrow and drop temperatures even
further before the low pressure system streams moisture into the region.
Heavy snow is also possible over the Ohio Valley and central Appalachians
on Tuesday. Lake effect enhancement may lead to an increased chance for
heavy snow downwind of Lake Eerie.

High temperatures will drop into the 40s and 50s across much of the South
behind the cold front associated with the deepening low pressure system
tomorrow, where some places can see temperatures exceeding 20 degrees
below average. This same trend will spread east into the central/southern
Appalachians down into Florida on Tuesday. Elevated Fire Risk is in effect
for parts of the high elevations of southern California through tomorrow,
due to dry and windy conditions.
