Area Forecast Discussion
National Weather Service Las Vegas NV
144 PM PDT Sat Apr 21 2018

.SYNOPSIS...Dry, quiet, and warm conditions are expected this
weekend into the upcoming week. Temperatures will reach their
highest levels of 2018 thus far.

.SHORT TERM...Today through Monday Night.

Clear and quiet conditions under high pressure will continue through
the short term period. Any significant weather will track well to
our north. Weak disturbances will bring occasional periods of high
clouds which could fiddle with high temperatures Sunday.
Temperatures in general will continue to warm through at least
Monday, reaching the low-mid 90s in Las Vegas, and upper 90s to
around 100 in Death Valley and along the Colorado River Valley by
Monday afternoon. No significant changes were made to the forecast
this afternoon.

.LONG TERM...Tuesday through Saturday.

Persistent ridge will remain over the area through mid next week
with temperatures near 10 degrees above seasonal normals. High
clouds will spill over the ridge on Tuesday and Wednesday but with a
slight breeze from the south to southwest these clouds shouldn`t
limit max temps very much. Closed low churning off the West coast on
Wednesday will slowly lift northeastward towards the Pac Northwest
Thursday and Friday. Models are not in good agreement with the
degree to which the ridge over the local area will weaken as a
result of approaching low and also in how much moisture the low can
successfully advect over the area. Currently, the impacts look to be
minimal through Friday night with breezy, south to southwest winds
and isolated, higher elevation precip over the southern Sierra
towards the end of next week.

.AVIATION...For McCarran...No significant winds or clouds expected
through the weekend.

For the rest of southern Nevada, northwest Arizona and southeast
California...Expect mostly clear skies and winds under 10 knots
through the weekend, except west winds possibly reaching 15-20 knots
in the Barstow area Sunday evening and night.

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


SHORT TERM...Wolcott
LONG TERM....Guillet
