Area Forecast Discussion
National Weather Service Las Vegas NV
224 PM PDT Sun May 28 2017

.SYNOPSIS...Hot and dry weather conditions are expected through the
remainder of the Memorial Day weekend.
&&

.SHORT TERM...today through Tuesday night.

High pressure over the western states today and Monday will bring
increasing temperatures to the region. High temperatures this
afternoon are expected to rise back above normal by a few degrees
and then add several more for Monday`s high. Some areas will have
lingering northerly winds to around 10 mph with local gusty winds to
25 mph near Laughlin/Bullhead City. Monday will see local gusty
northerly winds as well especially during the morning hours with a
decreasing trend through the day. Troughing off the west coast on
Monday moves into southern California/northern Baja on Tuesday
resulting in area wide southerly winds. No significant winds are
forecast and I don`t anticipate and wind hazard products will be
needed. The southerly flow will maintain well above normal
temperatures across the region on Tuesday.

Models forecast some weak instability over the Sierra the next few
afternoons. Provided enough moisture is available, daytime heating
and orographic lift could result in a few showers or thunderstorms.

.LONG TERM...Wednesday through Saturday. As in previous days, the
main concern is the evolution of a trough across the West during the
second half of the week. The models have not converged much if any
from previous days, so confidence remains below average. The best
chance of precip during the period will be Wednesday afternoon over
the northwest fringe of our CWA as troughing moves into California.
Thereafter, model spread increases and confidence in both placement
of mid level features and moisture availability is too low to
justify PoPs in any one area. Still expecting a downward trend in
temperatures for Wednesday and Thursday, perhaps down to near normal
Thursday before rising a few degrees Friday and Saturday.
&&

.AVIATION...For McCarran...Light and variable winds becoming
northeast later this morning and lasting much of the day. No other
operationally significant weather expected through the period.

For the rest of southern Nevada, northwest Arizona and southeast
California...Diurnally driven winds generally 10 knots or less are
favored for today. Dry and clear conditions are expected through the
period.
&&

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