A cool spring weather pattern on tap for the next few days for most areas
to the east of the Rockies.  A broad mid to upper level trof will remain
entrenched across much of the central to eastern half of the nation,
supporting below average temperature over the next few days for most areas
to the east of the Rockies.  High temperatures are expected to be 5 to 15
degrees below average across these regions. A small region across the
Central to Southern Plains will see high temperatures as much as 20 to 25
degrees below average over the next few days.  This will be associated
with an area of potentially heavy rains that spread east southeastward
across portions of the Central to Southern Plains from southeast Colorado,
western and southern Kansas, all of Oklahoma and northern Texas.  These
heavy rains may lead to isolate areas of flash flooding across these
regions.  Severe weather is also possible with this area of heavy rains,
especially along the southern edge of the heavy precipitation region
across northern and central portions of Texas. 

Farther to the south and west across the Southern High Plains, dry
conditions are expected to persist over the next several days.  These dry
conditions, combined with low relative humidities and gusty winds will
keep the fire weather threat at an elevated to critical level over the
next few days across large portions of New Mexico, far southeastern
Arizona and southwest Texas.  Fire Weather watches are currently in effect
across these regions.

The cool spring weather pattern will also support potential for widespread
frosts and freezes early Tuesday morning across the Upper Ohio Valley, the
Southern to Central Appalachians and portions of the Mid-Atlantic. Freeze
warnings and frost advisories are currently in effect for these regions. 
Morning temperatures will also likely fall to below freezing levels both
Tuesday and Wednesday mornings from the Northern Plains, into the Upper
Mississippi Valley and Upper Lakes regions.

While below average temperatures grip much of the central to eastern U.S.
early this week, above average temperatures will be expanding across much
of the western U.S.  This much above average temperature pattern will
likely continue through the remainder of the week with a gradual increase
in temperatures each day.  This may lead to some record high temperature
potential for portions of northern California, western Oregon and western
Washington State toward the end of the work week.
