.KEY MESSAGES...

* Gusty winds and cooler temperatures will spread across the
  region today.

* Light showers are expected across the southern Great Basin
  midweek as a low pressure system sits over central Nevada.

&&

.DISCUSSION...Today through the weekend.

A strong low pressure system will drop into the region from the
Pacific Northwest today. This system will bring cooler than normal
temperatures to the region with temperatures dropping around 7 to 15
degrees from today to tomorrow. Gusty southwesterly winds will
accompany this system with winds picking up later this morning as
this low pressure system and associated 30 to 50 knot 700 mb jet
move into the area. Elevated winds will linger across the region
into Thursday with southerly winds picking up across northern
Arizona tomorrow as the jet shifts overhead. Temperatures will
gradually increase during the second half of the week, returning to
near normal as we head into the weekend and the system clears out of
the area.

As the center of this low pressure system settles over the
southwestern Great Basin on Wednesday and Thursday, precipitation
chances will increase across Inyo County and the southern Great
Basin. Given the more inland trajectory of this system,
precipitation is expected to be light-to-moderate and favor areas of
higher terrain.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Gusty
southwesterly winds will be the rule through the forecast period.
Gusts early in the period will be around 25KT, quickly increasing
to 30-35KT through sunset. Winds and gusts will diminish somewhat
overnight, with sustained speeds dropping to around 15KT with
gusts to around 25KT, continuing thereafter. There will be some
variability in wind direction, generally between 200-240 true,
with winds expected to back more south-southwesterly Wednesday
late morning onward. VFR conditions will prevail with FEW-SCT
clouds at or above 15kft. Localized blowing dust will be possible
over dry lake beds outside of the Valley, potentially resulting in
some slantwise visibility reductions.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Gusty southerly to
southwesterly winds are expected across most of the region
today, with sustained speeds around 20-25KT and gusts to 30-35KT
common this afternoon through this evening. Near higher terrain
and in downslope-favored areas, there will be some variability in
wind direction, especially across the Owens Valley (including
KBIH) where west-northwesterly winds will gust to 35-40KT this
afternoon into tonight, becoming lighter thereafter. Across the
western Mojave Desert/KDAG, winds will remain westerly, with the
strongest gusts to 40-45KT this afternoon and tonight. Elsewhere,
winds diminish somewhat overnight but remain elevated around
10-15KT with at least intermittent higher gusts to around 20KT
expected. VFR conditions prevail with clouds generally at or above
12kft, though localized visibility reductions in blowing dust
will be possible.
