.SYNOPSIS...
Temperatures will remain above normal through the middle of the week
along with some gusty winds at times. Low confidence in the forecast
late-week, as we continue to assess the possibility for a return of
precipitation chances, gusty winds, and lower temperatures.
&&

.UPDATE...It was a warm and pleasant end to the weekend with highs
anywhere from 2-10 degrees above normal across the area. The
anomalous warmth and light breezes continue through mid-week. A
weakening system approaching from the south tomorrow will bring
widespread clouds and maybe even some sprinkles Monday
afternoon/evening, but otherwise dry conditions persist for now. By
mid/late week, a stronger system looks to move in and settle over
our area. Gusty winds, much cooler temperatures, and precipitation
chances (potentially even some storms) are expected as this occurs.
&&

.SHORT TERM...through Tuesday.
The trough that brought the cooler temperatures to the region today
is expected to form a closed low off the central California coast
Monday and eventually interact with a closed low currently off the
southern California coast. The low off the southern California coast
will eventually get kicked northeast into Arizona Tuesday as an open
wave. As this shortwave move through it is expected to increase the
PWs to around 150 to 200 percent of normal; however, there is very
little in the way of forcing as much of the energy should remain
east of Mohave County. Still, a few light rain showers will be
possible Tuesday over the higher terrain of Mohave County with
amounts generally a few hundredths or less. Elsewhere, temperatures
will remain several degrees above normal through Tuesday keep the
Heat Risk in the "Minor" category.


.LONG TERM...Wednesday through Next Weekend.

After a brief break in the action Wednesday: another, more potent
system may impact the region late Thursday into the weekend. In the
past 24 hours, models have taken a turn and are now trending towards
a solution where a Pacific Northwest low digs into the region and
phases with a low sitting off the southern California coast, rapidly
deepening somewhere over the western US as it does so. There is
significant model differences in how this will play out, then add in
the inherent low confidence in models resolving phasing systems-
there is high uncertainty in the forecast Thursday through the
weekend. The current "worst case" 90th percentile 48hr QPF has
significantly increased in the past 24 hours and suggest higher
impacts than what it was showing yesterday. There is now a 30%
chance for over 0.50inch of rain through the weekend in parts of
southern Nevada and western Arizona when it was showing less than
10% regionally at this time yesterday. Also of note, the spread in
high temperatures on Friday is anywhere from 5-10 degrees above
normal to 10-15 below normal. Winds would be the other concern with
this system as it deepens over the area- especially if we see the
colder solution (a significant drop in temperatures would suggest
gusty winds with a strong temperature gradient). All this to say-
there is potential for impactful weather the end of next week but
it`s too early to say if it will happen or what those impacts would
look like. Changes are expected in probabilities for impacts and
weather details with this system- Stay tuned!

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Light
south or southwest winds expected through around 8-9z before
uncertainty in a possible wind shift arrives. Winds may shift to the
northeast at 6-9 knots or remain light and southerly through the
remainder of the early morning hours. By daybreak, northeasterly
winds will overspread the valley if they haven`t already with a few
gusts to around 18 knots possible. Winds will ease through the day
and shift back to the south by Monday evening with increasing mid
and high level clouds with CIGS descending to around 15kft AGL.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Tonight, the strongest
northerly gusts of 15 to 25 knots are expected in the favored
terrain areas from southern Lincoln County through the
Laughlin/Bullhead City area. Winds are expected to become easterly
to southeasterly over much of the region on Monday, with only spotty
gusts over 20 knots. Mid level clouds will increase from south to
north late in the afternoon, with spotty virga and gusty winds.
