.nother storm to bring additional heavy snows to northern California
and southern Oregon.

A wet weather pattern for large areas to the east of the Mississippi
River.

Much above average temperatures expected for much of the lower 48 to the
east of the Rockies over the next few days.

Record high early morning lows possible from the Lower Lakes/Ohio
Valley into the Northeast.

An area of low pressure off the northern California/Pacific Northwest
coast will be moving slowly southeastward Tuesday and Wednesday to a
position off the central to southern California coast.  This storm will be
spreading additional moderate to heavy precipitation amounts into northern
California and southwestern Oregon over the next two days, with the
potential for additional snowfall totals of 1 to 2 feet from the southern
Oregon Cascades into the northern Sierra.  While these totals will be much
less than the previous more long lasting storm, travel will remain
difficult and the additional heavy snows will exacerbate recovery from the
first storm.   Winter storm warnings are in effect for the northern
Sierra, northern California Coast Range and into southern Oregon for
additional heavy snow amounts.  The good news for this area of the country
is that after the next round of heavy snows, more tranquil weather is
expected for the remainder of the week.

A wet weather pattern is in store for large areas of the lower 48 to the
east of the Mississippi River over the next few days.  This will be along
and to the east of a slow moving frontal boundary stretching southwest to
northeast from the Southern Plains into the Mid Mississippi Valley, Ohio
Valley and into the Northeast and ahead of two areas of low pressure
moving from the central Gulf coast up along the east coast.    Moisture
values expected to be much above average along and to the east of this
front and ahead of the two areas of low pressure moving along the east
coast, supporting the potential for widespread regions of precipitation. 
The heaviest rainfall totals expected from the central Gulf coast, across
portions of the Southeast and Mid-Atlantic where the two areas of low
pressure are expected to move across.  The lead area of low pressure will
spread rains across the Mid-Atlantic Monday night and into the Northeast
on Tuesday.  This will be followed by another low moving from the central
Gulf coast Tuesday night, into the Southeast Wednesday and the
Mid-Atlantic Wednesday night.  Rainfall totals of 1 to 2 inches possible
across these regions, with isolated areas of flash flooding possible,
especially in urbanized areas of the central Gulf coast. 

Much above average, spring like temperatures will persist for much of the
week for areas to the east of the Rockies.  Many areas will see high
temperatures Tuesday and Wednesday 15 to 25+ degrees above average.  The
warmest temperatures are expected across the Southern Plains into the
Lower Mississippi Valley where widespread highs in the 70s and 80s are
forecast. There are not expected to be any record high temperatures across
these areas over the few days, however, there is potential for widespread
record high morning low temperatures from the Lower Great Lakes into the
Northeast where the above mentioned much above average moisture values
will keep temperatures from cooling at night. Below to much below average
temperatures are expected from the Northern High Plains, Northern Rockies,
Pacific Northwest and northern California.  Across these regions, high
temperatures are expected to be approximately 10 to 20 degrees colder than
average on Tuesday and Wednesday.
