Upper-level energy will flow over the Great Lakes into the Northeast
through Monday morning, creating a deep upper-level trough over the
region. The energy will aid in producing lake effect snow over the Great
Lakes and upslope snow for the Central Appalachians/Northern New England
through Monday morning when the snow starts to wane. The highest snowfall
accumulations will be along the southeast coast of Lake Erie and the east
coast of Lake Ontario. Likewise, the highest snowfall amounts will be in
the upslope regions of the Central Appalachians/Northern New England. The
lake effect snow will taper off late Monday into Tuesday.

A deep upper-level trough associated with the upper-level energy, bringing
temperatures 15 to 25 degrees below average to the Upper Midwest into the
Northeast/Mid-Atlantic through Tuesday. In contrast, temperatures will be
15 to 25 degrees above average from parts of the Great Basin/Southwest to
the Southern Plains. In addition, an upper-level ridge over the Rockies
will allow temperatures to reach record or tied for record high
temperature over the southwestern portion of the country through Sunday.

Furthermore, an approaching deep upper-level low will begin to move
onshore over California Sunday night into Tuesday. Therefore, overnight
Sunday, light rain will develop over the West Coast, with higher elevation
snow over the Sierra Nevada Mountains by Monday. Overnight Monday into
Tuesday, the rain and higher elevation snow will move the Northern/Central
Rockies and Great Basin/Southwest.

In addition, the SPC has issued a Critical Risk of fire weather over parts
of the Southern High Plains Monday into Tuesday morning due to gusty
winds, low relative humidity, and dry fuels. The threat of an Elevated
Risk of fire weather continues on Sunday into Monday morning over parts of
the southern Mid-Atlantic Southeast and parts of Central- Southern Texas.
