Area Forecast Discussion
National Weather Service Las Vegas NV

.SYNOPSIS...A dry and warm weather pattern will hold over the
region through the weekend and much of next week.

.SHORT TERM...through Monday night. Quiet weather coming up for a
change as high pressure builds in. The next storm system passes by
well to the north Monday night before digging over the Rockies,
instead of sweeping through the Desert Southwest as the previous
several have done. Thus, the main concern will be temperatures, as
the warming trend which began in earnest yesterday continues through
Monday, when highs will be in the 90s at KLAS, nearing 100 down the
Colorado River, and over 100 in Death Valley. Expect no significant
winds through the period.

.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 15 knots
through the weekend, except west winds possibly reaching 20 knots in
the Barstow area Sunday evening and night.

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


LONG TERM...Guillet
