Area Forecast Discussion
National Weather Service Las Vegas NV
123 PM PDT Tue May 28 2024

.SYNOPSIS...Dry conditions will continue across the region
the next seven days with occasional breezy afternoons and
temperatures several degrees above normal each day.
&&

.DISCUSSION...through next Tuesday.

A dry weather pattern with no significant impacts will persist
across our region through early next week under a mean zonal flow
aloft. A few low amplitude troughs are forecast to swing across the
Pacific Northwest and brush the northern Great Basin enough to stir
up afternoon southwest winds 15-25 mph this afternoon and Wednesday
then again Saturday-Sunday. HIgh temperatures will remain several
degrees above normal and will only fluctuate a few degrees during
the entire period. Las Vegas will be within a degree or two of the
century mark this afternoon and Wednesday then will likely reach 100
or above Thursday through Saturday before pulling back slightly
Sunday and Monday.

The ensemble clusters are in quite good agreement at depicting a
broad high amplitude ridge beginning to build over the entire
western and central U.S. by next Tuesday followed be further
intensification the second half of next week leading to the potential
for a significant heat wave. One feature that may keep temperatures
from running away over our region is a cutoff low near the
SoCal/Baja Coast which is forecast, especially by the ECMWF
ensembles, to lift up the West Coast. There is not much indication
that the low will entrain any moisture, but will bear watching.

.AVIATION...For Harry Reid...Developing southwest winds early
this afternoon with gusts around 20 knots will persist into this
evening then speeds will diminish overnight through Wednesday
morning. South-southeast components 6-10 knots will be likely late
Wednesday morning through 22-23Z then southwest components should
develop. No significant cloud cover.

For the rest of southern Nevada, southwestern California, and
northwestern Arizona...South-southwest winds gusting 20-25 knots
will occur this afternoon into early evening across most of the
region followed by diminishing gusts after sunset and winds around
10 knots or less overnight through Wednesday morning. The exception
will be KDAG where gusts 25-30 knots will persist overnight then
diminish early Wednesday morning. South-southwest winds gusting 15-
20 knots will occur Wednesday afternoon across the Mojave Desert
Region and northwest winds gusting 15-20 knots for the Owens Valley
and central Nevada. No significant cloud cover through the TAF
period.
