.KEY MESSAGES...

* Clear skies and warming temperatures expected through tomorrow
  before gusty winds and cool temperatures return late-week.

&&

.DISCUSSION...Through Monday.

Temperatures will increase a few more degrees today and tomorrow as
heights aloft increase. Tomorrow's highs will be within a few
degrees of normal for mid-April, which for Las Vegas means highs in
the low 80s. A change in the weather pattern arrives on Thursday as
an area of closed low pressure, currently located off the coast of
British Columbia, dives southeast into the Great Basin. The primary
concern with this system is wind. Southwesterly prefrontal winds
ramp up in the Mojave Desert while northwesterly postfrontal winds
start to increase in the southern Great Basin on Thursday morning.
These winds include gusts between 35 and 45 mph, the strongest of
which should occur over high terrain. Winds remain elevated and
gradually shift north on Thursday night as the front moves south.
The strongest winds with this system are expected to occur on Friday
in the Colorado River Valley as a favorable north to south pressure
gradient develops. There is a greater than 80 percent probability of
wind gusts reaching 40 mph in that area and a 40 to 50 percent
probability of gusts reaching 58 mph in a localized area near
Bullhead City. Will continue to monitor model trends and assess the
need and timing of wind-related headlines. Besides wind, cold air
and lowering heights aloft bring a 10 to 15 degree temperature
decrease between Wednesday and Friday. Most moisture associated with
this system remains the north of the forecast area, but there is a
20 to 40 percent probability of light precipitation in Lincoln
County on Thursday and early Friday. Snow levels fall to between
2000 and 3000 feet on Thursday night as cold air moves in, meaning a
dusting of snow cannot be ruled out. Temperatures will rebound and
dry conditions return as ridging builds again this weekend, but
breezy southerly winds may continue for some of the area.

.AVIATION...For Harry Reid...For the 12Z Forecast
Package...Light winds will persist through the morning. A period of
southeast winds may develop later this morning,  but speeds will
remain under 8KT. By 21Z, winds will transition southwest and
increase, with gusts to around 20KT expected through the afternoon.
Gusts will drop around sunset, but elevated south winds at 8-10KT
will continue through the night. On Thursday, gusty southwest winds
are expected to start in the morning with gusts 20-25KT, then
continue to increase to around 30KT in the afternoon.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Light winds will
continue through the early morning before west to southwest winds
increase in the late morning and afternoon. Widespread gusts of 15-
25KT are expected, including at KBIH where a west push of winds is
likely between 23Z and 03Z. Winds will diminish after sunset except
around KDAG where west winds at 10-15KT will continue through the
night. Occasional high clouds are possible at times but VFR
conditions are expected through the period.
