Area Forecast Discussion
National Weather Service Las Vegas NV
730 PM PST Sat Dec 17 2016

.SYNOPSIS...A dry...cold northwest flow will continue to provide
below normal temperatures and northerly breezes for much of the area
the next couple of days. Stronger winds will occur down the Colorado
River Valley. Temperatures will slowly moderate through mid week.
&&

.UPDATE...Clear skies and cold temperatures this evening across the
forecast area with most areas seeing winds under 10 mph. The current
hard freeze warnings and wind advisories still look good. No updates
anticipated this evening. -Harrison-
&&

.PREV DISCUSSION...
235 PM PST Sat Dec 17 2016

.SHORT TERM...through Monday afternoon. Clear skies, dry conditions
and below normal temperatures will dominate the period. Temperatures
will fall into the lower 20s in many desert locations tonight and
again on Sunday night. A hard freeze warning is in effect for
southern Nye, western Clark County, the northwest deserts of Mohave
County and southern Clark County has now been added to the warning.
Temperatures in the Las Vegas Valley will fall into the mid 20s in
many locations away from McCarran and the central portions of the
valley. Outlying areas and may dip into the lower 20s in the far
western and southern portions of the valley. The latest data is
showing a degree or two of cooling Sunday night in the Las Vegas
with slightly lighter winds. If this pans out, Las Vegas may need to
be added to the Hard Freeze Warning for Sunday night. Only other
item of note will be gusty north winds around 40 mph down the
Colorado River Valley the next couple of afternoons.

.LONG TERM...Ridging will bring moderating temperatures into
Wednesday ahead of the next in the series of troughs set to impact
the area over the next week. Gusty north winds will be the primary
impact as a trough briefly brushes the area Wednesday. A more potent
trough will graze the area again Friday, however the track continues
to look unfavorable for precip, so strong winds look to be the
primary concern once again. A shower or two is still within the
realm of possibility and hard to rule out in Lincoln County. The
general model consensus heading into next weekend is amplification
of a west coast ridge ahead of the next batch of waves in the
northern Pacific.
&&

.AVIATION...For McCarran...Winds should remain under 10 kts and
switch to the south southwest this evening. Brief gusts in the teens
possible for the remainder of the afternoon. Mainly clear skies
will be seen through the day. North winds will return by 18Z on
Sunday with winds of 10-15 kts through the afternoon.

For the rest of southern Nevada...northwest Arizona...and southeast
California...Mainly clear skies through Sunday afternoon. Winds will
generally be northerly at 10-15 kts but stronger down the Colorado
River Valley...at IFP and EED.
&&

.SPOTTER INFORMATION STATEMENT...Spotter activation is not
anticipated. Spotters are encouraged to report any significant
weather according to standard operating procedures.

Short Term/Aviation...Czyzyk
Long Term...Steele
