.DISCUSSION...through next weekend.

A transient ridge will move through the region today and tomorrow,
strenghtening as it moves overhead. This will allow for dry
conditions to continue through Monday with temperatures continuing
to increase each day. Temperatures will top out around 4 to 8
degrees above normal this afternoon. Breezy southerly-to-
southwesterly winds will pick up across the region on Monday
afternoon as our next weather system approaches the West Coast.
These winds will allow for better mixing on Monday, which when
combined with the higher than normal 500 mb heights will allow for
temperatures 6 to 12 degrees above normal on Monday afternoon.

Winds will increase and become more widespread on Tuesday as the
aforementioned weather system begins to push into the region.
Currently, there is around a 70 to 90% chance for wind gusts of 40
mph or greater on Tuesday across the western Mojave Desert,
through Death Valley, and into the southwestern Great Basin. Given
these high probabilities for wind gusts hitting Wind Advisory
Criteria, wind headlines will likely be issued within the next 24
to 36 hours. On Wednesday winds will be lighter with elevated
southwesterly wind lingering across the Mojave Desert into
northwestern Arizona. In addition to gusty winds, the higher
terrain of Inyo County and the southern Great Basin will see
increased precipitation chances accompany this system Tuesday into
Wednesday. Precipitation totals will remain light with 0.50 to
0.75 inches of precipitation possible in the upper-elevations of
the Eastern Sierra and less than half an inch elsewhere. Speaking
of the Eastern Sierra, snow levels will be around 7,000 to 8,000
feet, allowing for a couple inches of new snow accumulation.
Outside of the Eastern Sierra, snow accumulations will be minor,
if any accumulates at all across the higher terrain of the
southern Great Basin. Temperatures will cool to around 5 to 10
degrees below normal by Wednesday, as the system exits the Great
Basin. Beyond Wednesday, troughiness will linger through the end
of the week, but temperatures will gradually rebound back up to
above normal.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will generally remain southwesterly, with a period of variability
this morning through early afternoon, and again at the end of the
forecast period. Wind speeds will remain around 5-7KT until late
this afternoon into early evening, when a brief uptick to around
10KT is expected. While intermittent higher gusts may result,
especially before sunset, confidence in this occuring is low. VFR
conditions prevail, with increasing mid-level and high clouds with
bases at or above 15kft.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Across the area, winds
will generally remain around 5- 10KT, following typical daily
directional patterns with some variability. In the Las Vegas
Valley, a brief period of elevated southwesterlies is expected
this afternoon through early evening, with speeds expected to top
out around 10-12kt. Additionally, across the northern Owens
Valley/KBIH, gusty up-valley winds are expected from mid- morning
through sunset, with gusts from 20- 25KT early expected to
increase to 25-30KT during the afternoon. Another exception will
be the western Mojave Desert in the vicinity of KDAG, where
westerly winds late afternoon through tonight are expected to gust
to 18-20KT. Otherwise, VFR conditions prevail, with increasing
clouds through tonight with bases at or above 15kft.
