.KEY MESSAGES...

* Mild conditions will continue across the region through the
  upcoming week.

* A disturbance will bring a 15-30% chance for precipitation to
  portions of Inyo and Esmeralda counties late week.

&&

.DISCUSSION...through next weekend.

A stagnant and dry pattern continues with broad ridging across
much of the southwestern US through the week. This will keep dry
and mild weather locked in, with daily temperature inversions
persisting in some of the lower valleys. The flow pattern aloft
will begin to deamplify by the weekend as the storm track sags
into Northern California. This will allow for increasing chances
for light precipitation by the end of the week and into next
weekend, but limited to the Sierra and Esmeralda County regions.
Elsewhere, dry and mild conditions will continue though a notable
increase in high clouds can be expected.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds
remain light and follow typical, daily patterns throughout the TAF
period. FEW to SCT high clouds will filter through the area as
well.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Light winds
following usual daily directional patterns continue through the TAF
period. The exception is the lower Colorado River Valley, where
northerly gusts of 15-30 knots persist through the afternoon. Winds
weaken after sunset but remain elevated near KIFP. VFR conditions
are expected with periods of high clouds.
