.DISCUSSION...through next weekend.

Late night radar and satellite imagery show ongoing showers across
Clark, Lincoln, and Mohave Counties as an upper-level trough pushes
into the area. This trough will continue its slow trek east today,
with isolated-to-scattered showers and thunderstorms expected across
the region today as a result. Moisture across the region will not be
as abundant as it was on Sunday when Rachel`s remnants moved
through, so widespread flash flooding is not expected to pose as
great of a threat today. However, isolated instances of flash
flooding will be possible with stronger storms that develop. In
addition to isolated instances of flash flooding, lightning, gusty
thunderstorm winds, and localized moderate-to-heavy rain will be
possible with storms today. The upper-level trough will continue to
dig through the region on Tuesday, with around a 20 to 50 percent
chance for isolated showers and thunderstorms across the Arizona
Strip, northeastern Clark County, and eastern Lincoln County on
Tuesday afternoon. By Wednesday, precipitation chances will have
disappeared from the area as the trough shifts off to our east.

In addition to showers and thunderstorms, this trough will also
breezy conditions to southern Nevada, northwestern Arizona, and
southeastern California. Breezy southerly winds are expected today
with peak gusts in the 25 to 40 mph range this afternoon. Winds will
shift to the northwest on Tuesday as a cold front swings through the
area, with breezier northerly winds lingering through the work week.
As the cold front moves through, some of the cities/towns in the
northwestern portion of our forecast area will have a shot at their
first freeze of the season. Currently, the NBM boasts an 80 to 95%
chance of freezing temperatures on Tuesday morning for the Bishop
and Dyer areas, where a Freeze Watch remains in effect. Looking at
the rest of the region, temperatures on Tuesday will run around 15
to 20 degrees cooler than normal. Beyond Tuesday, temperatures will
gradually rebound during the second half of the week with
temperatures approaching normal over the weekend.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Non-
impactful showers linger in the valley, mostly to the south of the
terminal. Breezy south winds linger into the late night before gusts
cut off and prevailing winds reduce. Additional shower activity
arrives in the early to mid morning, but does not look impactful.
Winds turn south-southwest into Monday afternoon and become gusty
with peak gusts around 25 kts. Shower activity exits into the early
night with winds becoming southwest and light.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Shower activity is
reducing and winds are starting to decrease. Winds across the region
become light in the late night. Light winds last through much of the
morning but breezy to gusty  south to southwest winds build in the
late morning and into the afternoon with spotty shower activity.
Showers exit into Monday evening with winds at most sites losing
their gusts and becoming light. KDAG, KBIH, and KIFP see some
reductions in wind, but remain breezy beyond the end of the TAF
period.
