...SHOWERS/T-STORMS MAINLY EASTERN NV TODAY...
...COOLER THAN NORMAL TEMPERATURES MODERATE INTO NEXT WEEK...

.METEOROLOGICAL CONDITIONS (FRI AM - THU AM)...

An active day of scattered showers and thunderstorms primarily
impacting the east slopes of the central/southern Sierra and points
downstream across much of the state of NV yesterday. This was
courtesy of a s/wv trof moving from the central CA coast yesterday
morning...reaching the central/southern Sierra and eventually the
state of NV during the afternoon and evening hours. This feature has
now exited the area to the northeast...making its way over eastern
MT.

General troffing continues to reside along the or just off the west
coast this morning with quite the marine layer push through the
Sac/SJ Delta into the Central Valley near Sacramento. A few showers
still remain farther inland over northeast NV and the southeast CA
deserts as another weak ripple in the flow moves across the area.

This afternoon still promises another round of showers and
thunderstorms primarily over the eastern half of NV and possible the
crest of the central/southern Sierra with just enough moisture and
instability in place. Then by Saturday and Sunday...the troffing
along the west coast weakens while another disturbance dropping
south along 140W rebuilds the troffing farther offshore between 140W
and 130W. This will bring drier southwest flow to the region with
the opportunity for precip diminishing across the entire area into
the following week.

Temperatures will be cooler than normal and bottom out either today
or tomorrow across the region with anomalies running from minus 5-
to minus 20-degF. Into next week...temperatures will moderate a bit
with the troffing shifting farther offshore...being slightly below
normal for western areas and slightly above normal for eastern
areas.

Freezing levels are currently from 13000- to 14500-feet across the
region and will fluctuate a little through the weekend. Then by next
week...these will begin to increase into the range of 16000- to
18000-feet by late Wednesday into Thursday.
