.KEY MESSAGES...

* Warmer than normal temperatures will continue through the week,
  with periods of breezy northerly winds down the Colorado River
  Valley through Wednesday.

* Cooler temperatures expected over the weekend and early next week,
  but conditions remain dry.

.DISCUSSION...through next Monday.

Little change in the overall pattern as high pressure remains firmly
over the West Coast. This will keep temperatures well above normal
allowing for near record temperatures Wednesday through Friday. See
the CLIMATE section for more information regarding records. A weak
trough over northern Mexico has helped increased surface gradients
over the lower Colorado River Valley which has helped bring gusty
north winds to areas south of Davis Dam today. These gradients will
remain through Wednesday keeping breezy to windy conditions in
place. Winds gusting to around 35 mph will be seen along with wave
heights of 2-3 feet, but due to the isolated nature of these winds,
no products will be issued. Extra caution should be used while
boating in areas south of Davis Dam.

By this weekend, the ridge will flatten as a shortwave moving
through the mean flow passes across southern California, Arizona,
and northern Mexico. While no precipitation is anticipated with this
feature, an increase in high cloud cover is expected, which will
also help lower temperatures several degrees.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...Winds
will follow typical diurnal directional patterns through the
forecast period, remaining light with speeds around 6KT or less.
VFR conditions prevail with a few high clouds around 25kft at
times.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...With the exception of
the Colorado River Valley, winds across the region will remain
under 10 knots and will follow typical daily directional trends. Winds
in the Colorado River Valley will favor a more northerly direction
through the TAF period, with 20 to 30 knot gusts dropping off during
the evening hours before returning overnight, continuing through
tomorrow afternoon. VFR conditions will continue through the TAF
period with no operationally significant cloud cover expected.
