...SCATTERED PRECIP TODAY AND EARLY TUE MAINLY FAR EASTERN AREAS...
...DRY AND WARMER CONDITIONS RETURN WED INTO THE UPCOMING WEEKEND...

.METEOROLOGICAL CONDITIONS (MON AM - SUN AM)...

An area of low pressure currently in the vicinity of Sacramento is
continuing its trek slowly to the southeast this morning. One area
of showers associated with this feature is primarily in the
northeast quadrant where diffluent flow aloft is resulting in
scattered showers and t-storms moving from south-to-north over
northwest NV. The other is a relatively solid line of showers that
have shifted from the San Diego area eastward across Imperial
County...where PW values are running quite high this morning with
the 28/12Z KNKX RAOB recording 1.79-inches of PW in a fairly moist
column from approx 850-mb to just above 500-mb. As the primary
circulation continues to move toward the southeast today...look for
the best precip to develop over far southeast NV and far eastern CA
with amounts in the wettest locations approaching 1.00-inch through
early Tuesday. Also...will continue to see scattered light precip
over the southern Sierra up into central NV.

Through tomorrow...the upr low will exit across the lower Colorado
River basin and shift off toward the east. In the wake of this
system...high pressure will begin to build from the eastern Pacific
eastward and become the dominating feature into the upcoming
weekend. This will bring above normal temperatures with anomalies
for afternoon highs peaking anywhere from plus 5- to localized
pockets of plus 20-degF along coastal areas. Also...dry conditions
will persist from Wednesday through at least Sunday...if not beyond
as models are not showing any hints of widespread precip through the
middle of October.
