Area Forecast Discussion
National Weather Service Las Vegas NV

.SYNOPSIS...
Quiet weather is expected over the weekend and into early next
week. Temperatures will begin a warming trend; reaching back up to
near seasonal normals by Tuesday.

&&

.SHORT TERM...Today through Sunday.

The previous winter storm system is currently located over northern
Arizona and will continue to push eastward into New Mexico tonight
and tomorrow. In its wake, the gradient remains tight enough to
support gusty, north to northwest winds through this evening
across much of the area. With a drier airmass in place, temps will
drop off quickly after sunset reaching values 10-15 degrees below
seasonal normals. Temps will be especially cold for the Kingman
area of northwest Arizona overnight with plenty of snow on the
ground and lows near 20 degrees so have decided to go ahead and
issue a Hard Freeze Warning for this area. Weak, dry, northwest
flow will take over for the weekend leaving the weather fairly
quiet. Winds will lighten up and temps will warm 2-5 degrees each
day. There is a small possibility that the snowpack melt over the
lower elevations of Mohave County could create some minor,
nuisance flooding issues over the weekend but the warmup should be
gradual enough to limit any issues.

.LONG TERM...Monday through Friday.

Nearly zonal flow will allow for a relatively quiet weather period
in the long term. The exception will be the Sierra and Owens Valley
where an incoming, northern Cali moisture plume and cross-range flow
over the Sierra will help support orographically induced activity
Monday through Wednesday. Spill over into the Owens Valley and
White Mountains will be possible. Rain and snow accumulations look
to be light. Elsewhere, dry conditions, periods of breezy winds,
and warming temps can be expected. Max temps will be back up to
near normal by Tuesday and continue to rise to a few degrees
above normal by Wednesday/Thursday.

&&

.AVIATION...For McCarran...Gusty northwest winds are expected to
continue into the late afternoon; gusts up to 25 knots. Winds will
rapidly diminish between 00-02z with light west to southwest winds
overnight. Light and variable winds expected Saturday with not
operationally significant cloud cover. Dry, warming conditions
through the weekend.

For the rest of southern Nevada, northwest Arizona and southeast
California...Gusty north winds will diminish this evening and remain
light through Saturday. No operationally significant cloud cover is
expected through the period.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
