.SYNOPSIS...Abundant Pacific moisture will move across the region
through Thursday night bringing valley rain and mountain snow.

&&

.SHORT TERM...Tonight through Saturday. Mostly cloudy across the
region as a very moist air mass is pushing in across California
and into western Nevada. Valley rains and high elevation snow will
increase tonight into Thursday with moderate QPF amounts expected.
Ahead of this systems frontal passage, southerly winds will become
breezy on Thursday. Strongest winds will be over east-central NV.
A wind advisory has been issued for White Pine County for
Thursday. Strongest winds will be over higher terrain. Snow levels
will remain above 8000 feet through Thursday afternoon, then begin
to lower toward valley floors Thursday evening from northwest to
southeast across the CWA into Thursday night. Most areas will be
dry late Friday morning into the afternoon, however a little more
lighter precipitation is expected into Friday evening, mainly
across northeastern NV. Cooler on Saturday with scattered snow
showers across the region.

.LONG TERM...Saturday night through Wednesday. The weekend and
next week should see a closed low translate across northern NV
this weekend before moving southward to Arizona early next week.
The system then begins to cut off from the flow with the low
remaining over the desert southwest through the week This system
looks to remain fairly moist through the weekend which should
continue showers across Nevada through Sunday. The main region of
showers should be around the upper level of the low center in
northern NV. The atmospheric profile will be cold enough that the
showers should be snow. This snow will not last as diurnal heating
will quickly melt any accumulations in the lower elevations. As
the system moves southward it will draw dry air into the region
drawing down the shower activity. South Central NV may still see
some showers during the week as the flow around the low center may
still move a little moisture to that area. NV can see gusty
afternoon winds each day with the passage of this system.
Temperatures should warm through the week as a ridge starts to
build across NV with the low moving to AZ.

&&

.AVIATION...A storm system is passing through the region bringing
cloud decks and rain showers to all terminals. Cloud decks should
range between MVFR and VFR with the chance for IFR during the
overnight hours. The clouds will cause mountain obscuration
conditions through out NV. Rain showers will lower visibility with
MVFR visibilities possible in heavier showers.

&&

.HYDROLOGY...Rainfall will intensify from tonight through early
Friday. Storm total rain of a quarter inch to a half inch are
likely across the region, with locally higher amounts of an inch
or so possible by Friday morning. Product RNOESFLKN has more
information on this event.
