What forecasters said that day

The local office's own words before this high wind watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Las Vegas, NV wrote its last area forecast discussion before this high wind watch went out at Apr 9, 9:15 AM PDT, 5 hours 7 minutes earlier.

Area forecast discussion, Apr 9, 9:15 AM PDT, 5 hours 7 minutes before
Area Forecast Discussion
National Weather Service Las Vegas NV
915 AM PDT Mon Apr 9 2018

.SYNOPSIS...Dry and warm weather is expected across the area early
this week. Outside of strong north winds forecast in the Colorado
River Valley today, winds will be light to breezy at other
locations. High pressure moving in from the west will raise
temperatures through mid week before a potent system later this week
brings strong winds, cooler temperatures and a chance of
precipitation to parts of the area.
&&

.UPDATE...North winds in place across much of the area with a fairly
strong north/south gradient (10+ mb ELY/EED) in place across
southern Nevada and northwest Arizona. The gradient has begun to
slowly weaken and expect winds to trend slightly lower during the
afternoon hours. Winds have been 20-25 kts in Laughlin and the Lake
Wind Advisory looks good. Otherwise, have increased temperatures a
couple of degrees in most locations for today based on current
trends and the latest guidance. No other updates planned this
morning.
&&

.PREV DISCUSSION...
351 AM PDT Mon Apr 9 2018

.SHORT TERM...Tonight through Wednesday night.

High pressure over the region will lead to warm and dry conditions
today into Tuesday. Some northerly winds will remain down the
Colorado River Valley today with occasional gusts approaching 40
mph. These winds will be strongest in the morning with winds
diminishing during the afternoon. No changes to the Lake Wind
Advisory, but looking at timing it may end up being cancelled
earlier than 5pm.

Shortwave will approach the west coast Tuesday and Wednesday pushing
the ridge east and leaving the area in a dry southwest flow. With
increased mixing Tuesday afternoon temperatures will jump about 5 to
10 degrees above todays highs and we will see some locally breezy
conditions in the afternoon over portions of the area. The trough
off the west coast will deepen Wednesday and increase the southwest
flow over the area. Winds by afternoon will generally be 15 to 25
mph with some gusts approaching 35 mph. There will be some limited
moisture with this shortwave and any showers will be confined to the
Sierra and possibly the higher terrain of Esmeralda County.

.LONG TERM...Thursday through Monday.

A trough of low pressure will dig across the region late WED
- early THU bringing strong winds and much cooler temperatures.

By early Thursday morning, southwest to west winds will be near apex
across much of the region, especially across San Bernardino and
Clark counties. ECMWF MOS guidance has trended up in wind speeds and
now has peak sustained winds of 40 kts for LAS early THU whereas GFS
MOS has trended down a tad from 34 kts to 33 kts. The GFS and ECMWF
700mb winds have consistently been between 60-70 kts around the base
of the trough as it digs across our area. In addition, GFS NSharp
soundings are showing some downslope potential on the leeward side
of the Spring Mountains overnight WED-early THU morning with a clear
inversion. GFS9km cross section is also showing 60-70 kt downslope
flow reaching Summerlin/Red Rock area early morning THU as well.
Providing sufficient model consistencies over the last few days,
widespread wind advisories and some high wind warnings will likely
be needed in the coming days. Gusty winds will likely continue
behind the strong cold front as well. Timing of the cold front has
been fairly consistent over the last few days and should be sometime
late morning to late afternoon Thursday. In the wake of the frontal
passage, expect gusty northwest winds and much cooler temperatures.
There is still come uncertainty with the intensity of the northwest
winds THU afternoon-early Friday, but wind speeds look like they
should meet wind advisory criteria for portions of our CWA. Models
have been consistent in dropping temperature 15-25 degrees by THU
afternoon. Limited moisture with this system should keep slight
precipitation chances mainly limited to the northern reaches of our
CWA through THU where some light rain and snow showers will be
possible. Main precip impacts will be on the eastern Sierra, but
with snow levels remaining fairly high snow accumulations should
remain light (1-2 inches).

Ridging moves over the region by late Friday into Saturday, but may
be brief as another weather system begins to move in sometime late
Sunday-Monday. With brief ridging in place Saturday-Sunday, expect
calmer conditions and temperatures climbing back to near normal.
&&

.AVIATION...For McCarran...Northerly gradient over the area has
allowed winds to remain northwest to occasional northerly overnight.
Winds are expected to become more northeast after 15z with speeds
between 10-15 kts with occasional gusts to 20 kts which should
remain through the afternoon. Winds will diminish this evening and
may even go southwest drainage after 04z. Skies will remain clear.

For the rest of southern Nevada, northwest Arizona and southeast
California...A departing cold front has left a north wind regime in
its wake. These north winds will linger through today, especially at
sites along the Colorado River where gusts of 25-30 knots are
likely. Elsewhere, lighter north to northeast winds are expected.
Anticipated clear skies through the period.
&&

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