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

Latest WV/IR imagery shows a s/wv trof moving across the Pacific
Northwest this morning with the southern extent of the cold front
dragging across northern CA into northern NV. Over the past 24 hours
the best precip has fallen along the coast from the Smith River
basin down toward the lower portions of the Klamath River basin with
totals from 1.00- to 2.00-inches. However...there has been little
progressing inland of widespread measurable precip with a few
hundredths at best making their way to the upper Klamath River basin
and above Shasta Lake.

For today...the s/wv trof will quickly make its way farther inland
toward the northern Rockies near the MT/Canada border...and precip
will dissipate first across northern CA (primarily near the CA/OR
border)...and then far northern NV mainly north of I-80.
Also...temperatures will be at their coolest for the week ahead with
below normal temperatures for much of northern/central CA and the
northern third of NV...with slightly above normal for southern NV
and the southeast CA deserts.

The shift to some of the warmest/hottest temperatures of the year
will then take place for Tuesday through Thursday as high pressure
builds over the region. High temperatures will ramp up and become
anywhere from plus 10- to plus 20-degF over seasonal norms. Then by
the end of the week...the upr ridge axis will push far enough
downstream to allow southwest flow aloft to develop across the west
coast. Temperatures will still remain above normal...but not as warm
as the middle of the week (about plus 5- to plus 15-degF over
seasonal norms). Also...there does appear to be the opportunity for
afternoon and early evening showers/t-storms to develop across the
crest of the Sierra and portions of northern NV.
