.SYNOPSIS...Temperatures gradually decrease each day through
the weekend. Breezy southwesterly winds will pick up across the
area today and tomorrow as a shortwave moves through the Great
Basin. Our next weather system will arrive over the weekend,
bringing gusty winds and cooler than normal temperatures to the
region.

.UPDATE...Looking at the early morning visible satellite images, a
band of mid and high-level clouds is moving across central portions
of the area.  A few weak returns are noted on radar, but this is
likely virga, and no precipitation is expected to reach the ground
except maybe a few drops on the highest peaks across southern Nevada
north of the Vegas valley.  Temperatures this afternoon will be 1 to
3 degrees cooler than yesterday, but still 3 to 6 degrees above
normal.  Winds are still expected to pick up this afternoon, with a
few gusts of 30 to 40 mph possible across the western Mojave Desert.
Winds elsewhere will generally be 20 to 25 mph this afternoon.  The
current forecast looks good, and no changes were needed to the grids
this morning.

.SHORT TERM...through Thursday.

Temperatures today will be a few degrees cooler than yesterday as we
see 500 mb heights begin to decrease as a shortwave trough begins to
move through the Great Basin. In addition to slightly cooler
temperatures, we will also see breezy southerly-to-southwesterly
winds pick up across area today and tomorrow with the strongest of
these winds occurring in the western Mojave Desert where 30 to 40
mph wind gusts are expected. Mostly sunny to partly cloudy skies are
expected across our forecast area as this shortwave drives mid-to-
high clouds through southeastern California, southern Nevada, and
northwest Arizona. Weather on Thursday will be very similar to today
with breezy southwesterly winds, similar temperatures, and mid-to-
high clouds filtering through the area.


.LONG TERM...Friday through Wednesday.

A fairly deep trough will take shape off the West Coast on Friday
and shift inland over the weekend. Overall, ensemble agreement has
come into pretty good agreement on the general idea with this
system, though there remains some uncertainty into how quickly the
system departs early next week. Nonetheless, gusty winds will
overspread much of the region Friday and Saturday in advance of the
trough, along with sharply cooler temperatures Saturday and Sunday.
Precipitation expectations remain fairly limited, with the best
chance for light rain and high elevation snow possible the Sierra
and southern Great Basin. However, cold air aloft under the trough
axis over the weekend could result in at least some isolated terrain
driven showers as far south as Las Vegas, so trends will continue to
be monitored for any necessary bumps in precip chances.

By early next week, heights will gradually rise as the weekend
trough departs. As mentioned previously, how quickly it departs
remains a little uncertain but a general warming trend is still
likely to begin Monday and temperatures returning to near normal or
slightly above normal by midweek.
