...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.
