.DISCUSSION...through Wednesday.
Our next system remains on track to impact southeastern California,
southern Nevada, and northwest Arizona tomorrow as a trough swings
through the area. This trough will bring gusty southwesterly winds
to the region, with multiple wind headlines in effect for portions
of San Bernardino County and the Spring Mountains of Southern
Nevada, where 40+ mph wind gusts are expected throughout the day
tomorrow. Elsewhere, wind gusts will top out in the 30 to 40 mph
range with isolated 40+ mph gusts possible in areas of higher
terrain. Starting early tomorrow morning, localized 40+ mph
southerly downslope winds are expected across Highway 95 near Desert
Rock-Mercury. However, due to the isolated nature of these winds, no
wind headlines have been issued at this time. Outside of winds, this
system will also bring a 30 to 60% chance of isolated showers to
the higher terrain of Inyo County and the Great Basin. With snow-
levels around 9,000 to 10,000 feet, precipitation is expected to
fall as rain outside of the Sierra Crest, where they will see
their first dusting of the season with an inch or two possible
along the ridgeline.
The progressive nature of this system means that it`ll be out of our
area by Saturday. In its wake, drier conditions, cooler
temperatures, and lighter breezes. Ensembles continue to indicate a
reloading/persistent trough over the western US through the middle
of next week, which means the aforementioned conditions are likely
to linger, albeit with a slight moderation in temperatures toward
seasonable values.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds
follow typical diurnal patterns today, with light and variable
winds settling in from the southeast later this morning before
picking up and swinging around to the southwest in the afternoon.
As winds swing around to the southwest this afternoon, sustained
speeds will increase to around 10-12KT, with intermittent higher
gusts to 18- 20KT expected. These gusty southwesterly winds will
continue into the evening hours. Thereafter, winds remain
southwesterly, with gusts diminishing through early morning when
gusts to 20-30 knots return through the end of the period. VFR
conditions prevail with FEW-SCT clouds with bases around 25kft.
For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Winds will generally
follow diurnal patterns through the forecast period. Winds shift
to the south to southwest this afternoon, increasing to around
10-15KT with gusts to 18-22KT common. Up-valley gusts closer to
25KT are expected in the Owens Valley this afternoon, and across
the western Mojave Desert, gusty westerly winds are expected to
hold off until the evening, with gusts to 25-30KT expected there
through the night. Otherwise, VFR conditions prevail with passing
mid and high clouds, and showers expected to develop across the
Sierra Crest this afternoon and evening.
