.DISCUSSION...through Wednesday.

Current infrared and water vapor satellite imagery shows ridging
over southern Nevada, southeastern California, and northwestern
Arizona with a weak disturbance off the coast of southern
California. This ridge is responsible for the dry and warm weather
of the past few days, which will continue through Friday. Cloud
cover will increase across the region as the aforementioned
disturbance off the coast of southern California weakens and drifts
through the Southwestern US. These clouds will be the only noticable
impact from this disturbance drifting overhead, with cloud cover
decreasing on Friday.

Temperatures will cool down over the weekend, decreasing around 5 to
10 degrees from Friday to Sunday with additional cooling expected
early next week. This weekend cooldown is a result of a shortwave
rolling through the Northwestern US, which will knock down 500 mb
heights over our forecast area. Given the dry inland track of this
system, precipitation chances are limited to the panhandle of
Lincoln County where there is around a 20% chance of precipitation.
As this shortwave ejects into the Plains, we will find ourselves
under northwesterly flow aloft. This northwesterly flow will leave
the door open for additional systems to drop into the area early
next week, which will result in additional cooling and the potential
for some breezier winds.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will remain under 8 knots, tending to favor typical daily
directional trends with occasional periods of light and variable
winds. VFR conditions will persist through the TAF period with FEW
to BKN high clouds AOA 15 kft filtering through the area.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds across most of
the region will remain light, 10 knots or less, and will follow
typical daily directional patterns. The exception is IFP, where
northerly winds gusting to around 25 knots are expected,
throughout the day. VFR conditions will persist through the TAF
period with high clouds AOA 15 kft filtering through the area.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
