SYNOPSIS...

A few light showers early this morning with a dry weather expected
through at least early next week. Temperatures will remain on the
cool side through the end of the week. High pressure returns for
the weekend with warm and dry weather.

&&

.SHORT TERM...

A few showers developed overnight around the I-80 corridor in
western Nevada along the nose of a strong anti-cyclonic jet with
amounts around 0.05". Showers should begin to dissipate and move
into the Basin and Range early this morning with another 0.05"
possible.

Trough developing over the four corners area will slow the
progression of the building ridge moving into the region. Cold
mid-level air and northerly flow on the backside of the low will
keep temperatures cool Thursday and Friday before a strong warming
trend takes hold for the weekend.

Northwest surface flow today will become northeast on Friday
allowing cooler air to continue to push into the region and keep
below average temperatures in the forecast through the end of the
week. Temperatures on Friday will remain 5 to 8 degrees below
average with a a brisk northeast wind. Winds will generally be in
the 15-20 mph range with a few gusts to around 30 possible.
Stronger winds will be possible Friday afternoon into Friday night
in the high Sierra as a strong temperature gradient forms.

By Saturday ridging will begin to build into California and
western Nevada bringing light winds, clear skies, and warming
temperatures. Light easterly flow will keep temperature around
average for this time of year with upper 60s in w. Nevada and near
60 for the Sierra. -Zach


.LONG TERM...Sunday through Wednesday...

Main changes were to warm temperatures for next week as the models
are going back to their old solutions of having the East Pacific
ridge nosing in more. Sunday will be a mild day with a typical west
wind returning late in the afternoon. Highs in the 60s and 70s look
good for all areas.

For Monday and Tuesday next week, the ridge is a little further east
than previous runs showed. It still remains off the coast, but the
backdoor cold front that was progged earlier is now washing out as
it moves through Nevada. Therefore, little if any cooling is
expected. Instead, it looks to keep temperatures from warming
further.

Then, for mid to late in the week, the mean ridge looks to go
through a period of discontinuous retrogression. A portion of it
will move east over California and Nevada for Wednesday into
Thursday before it reforms more toward 140W next weekend. At least
for the end of next week, it looks to be quite warm, possible 10+
degrees above normal but not record setting. Wallmann

.AVIATION...

Lighter winds are expected today form the NW with peak gusts to 25
kts, strongest near KHTH, KNFL and KLOL. Peak speeds will occur
between 19 and 02Z today before becoming light. Limited areas of mtn
wave turbulence with it moderate at best, otherwise VFR.

Winds will become more northerly on Friday at similar speed, but VFR
conditions and light winds are expected this weekend. Wallmann
