.DISCUSSION...through Sunday.

Temperatures across the region will top out around 6 to 10 degrees
above normal today and tomorrow as we continue to find ourselves
under higher than normal 500 mb heights. Light winds and dry
conditions will accompany these above normal temperatures along with
mid-level and high clouds filtering through the Southwestern US
today and tomorrow.

A shortwave trough will move through the Great Basin during the
middle of the week, resulting in an uptick in winds, a decrease in
temperatures, and a slight chance of precipitation for the eastern
Sierra Crest. Winds across the area will peak on Wednesday, with the
NBM continuing to paint the northern Owens Valley and eastern Sierra
with the strongest winds of the event, indicating the potential for
gusty downslope winds. Currently, guidance shows peak wind gusts in
the 40 to 55 mph range for the northern Owens Valley with stronger
winds in the eastern Sierra and their foothills. Elsewhere, peak
wind gusts are expected to be in the 20 to 40 mph range with
isolated gusts in excess of 40 mph in areas of higher terrain. As
this system rolls through, the eastern Sierra crest will see a 15
to 30% chance of light precipitation on Wednesday, with liquid
precipitation totals of 0.20 inches or less and a dusting of snow
possible. As 500 mb heights decrease with the passage of this
system, we will see temperatures gradually return to more seasonal
values by Thursday. Beyond Thursday, we will see the return of
mild weather as ridging attempts to reestablish itself over the
Southwest as we head into the weekend.
