.SYNOPSIS...A mean trough will hold over the western states this
week into the holiday weekend resulting in dry conditions, mainly
clear skies, seasonal temperatures, and gusty afternoon winds.

&&

.SHORT TERM...Today and Thursday.

Strong high pressure centered over the Pacific Ocean will continue
to allow storm systems to bring weather impacts to areas mainly
north of us through Thursday. A leading shortwave ahead of its
parent low over the PacNW will move across northern Nevada this
morning with little fanfare but will then be followed by the main
low which will result in gusty southerly winds across much of the
region this afternoon. The strongest winds will over the higher
elevations of the Sierra, the western parts of San Bernardino
County, and across southcentral Nevada where gusts of 25-35 mph
are expected. The gusty conditions will continue across our
southern deserts tonight and Thursday. No significant winds are
anticipated and no wind headlines are in effect. However, the
gustiness could result in increased driving difficulties for high
profile vehicles as well as raise dust downwind of dry lake beds
causing some reduction in visibility at times.

The track of the system should keep any shower activity confined
to areas north of our area. Otherwise, clear and dry conditions
along with seasonal temperatures are expected through Thursday.

.LONG TERM...Friday through Tuesday.

Lower than normal heights in place across the area early in the
period Friday and Saturday. Models do show a shortwave trough moving
through California/southern Nevada Friday/Friday night, then it
quickly moves east across Arizona Saturday. Therefore, the beginning
of the long Memorial Day Holiday Weekend will be windy across the
western Mojave Desert with gusts 30-40 mph both days for Barstow and
Fort Irwin. Elsewhere, for the Lake Mead NRA and Lake Havasu
stronger gusts of 20-30 mph will occur Friday, with gusts in the 15-
25 mph range Saturday.

There will be a slight chance for showers and thunderstorms from the
southern Sierra of Inyo County northeast into east central Nevada
Friday. On Saturday any lingering shot for a shower or thunderstorm
will be in east central Nevada.

Looks like a great second half to the long weekend with rising
heights Sunday-Tuesday. Temperatures will be on the rise while winds
for those heading to the large reservoirs will be less of an impact.
