Area forecast discussion

Synopsis...winds will decrease Sunday, and a significant warming
trend is expected for the upcoming week.
Discussion...winds down the Colorado River valley have been
flirting with advisory criteria today, and will let the Wind
Advisory and red flag warning go until their scheduled expirations.
Once the wind settles down this evening, the main story will be
significant warming through the upcoming week. Temperatures will
rise about 15 degrees from today to Tuesday, then after a pause on
Wednesday, rise another five degrees or so Thursday. Most areas will
see the warmest temperatures of the year so far on Thursday and
Friday. The models are starting to come into better agreement for
another storm system to affect the West Coast next weekend, digging
it sharply southward along the coast. This would bring mainly
increased winds for our area, with any precip chances limited to the
higher terrain of southeast California. There is plenty of time to
watch this storm, and the details will likely change over the next
several days. Stay tuned.
Fire weather...the red flag warning for the Colorado River valley
will be allowed to expire this evening. Lighter winds are expected
Sunday, then a significant warming trend is on tap for the upcoming
Aviation...gusty northerly winds will subside and become
increasingly light and variable tonight with lighter winds following
typical diurnal trends for Sunday. No operationally significant
weather expected for the latter half of the taf period.
For the rest of southern Nevada...northwest Arizona...and southeast
California...gusty winds subsiding this evening for all terminals
with light winds expected for Sunday outside of lingering north
breezes in the Colorado River valley. Otherwise, no significant
weather expected for the later half of the taf period.
Spotter information statement...spotters are encouraged to report
any significant wind impacts according to Standard operating
