.KEY MESSAGES...
* Quiet weather expected until our next system arrives Friday,
  bringing precipitation chances to the Great Basin and dry, gusty
  conditions elsewhere.
&&
.DISCUSSION...through Tuesday.
Not much change to the forecast over the next 7 days. Dry,
southwesterly flow holds through Thursday, keeping temperatures near
seasonable values and precipitation chances below 10% areawide. On
Friday, a stout and compact shortwave is expected to move through
the region. Precipitation chances are largely confined to the Sierra
and Great Basin where NBM PoPs are 25-50%. With snow levels around
9,500-10,000 feet, the Sierra crest will likely (60% chance) see
1-4" of snow with this system. Elsewhere, where precipitation
falls, it will be in the form of light-to-moderate rain. Farther
southeast, places that don`t see any precipitation will mainly
have to contend with gusty winds. Widespread gusts of 25-40 mph
are expected, with our typical southwesterly wind belt (western
San Bernardino County to northeastern/central Mohave County)
having 25-50% odds of exceeding 40 mph. Should trends continue,
wind headlines may be warranted for these areas. By Saturday, the
system will be off to our east, leaving drier and cooler
conditions in its wake. Winds won`t be as strong as Friday, but
may remain elevated as troughing lingers over the western US into
next week.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will continue following diurnal directional patterns, becoming
light and variable around daybreak before shifting to the
southeast by late morning, and to the southwest late afternoon.
Winds will remain around 10KT or less, with a few sporadic higher
gusts possible late afternoon through early evening during peak
heating. VFR conditions prevail with dissipating high clouds
around 25kft.
For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds generally follow
diurnal directional patterns across the region today, with speeds
remaining around 10KT or less. Exceptions will be in the Owens
Valley, where a brief period of gusty up-valley winds is expected
around KBIH late afternoon through sunset, and across the western
Mojave Desert where westerly winds will persist around 10-12KT.
VFR conditions prevail, with FEW-SCT clouds around 20-25kft giving
way to clear skies by this afternoon.
