Discussion...

A dry southwest flow will prevail this week with high temperatures
remaining a few degrees above average this week before heating up
into the upper 90s by the weekend across western Nevada valleys.

A weak upper level trough will begin to increase mid and high
clouds tonight across northwestern Nevada with cloud cover
spreading south through the day Wednesday. Could see some slight
enhancement to afternoon breezes Wednesday afternoon but looking
to stay in the 25-30 mph gust range mainly north of Interstate 80.
Very isolated areas of low end critical fire weather conditions
Wednesday are possible but any such conditions will not last long.
The trough doesn't look amplified enough however to trigger
precipitation.

The trough will move through by Wednesday night into Thursday
which will bring about a wind shift out of the north-northeast
which could bring some smoke impacts to the Mammoth Lakes area
from The Springs wildfire in Mono County. Dry air aloft will mean
continued poor to moderate humidity recovery tonight and
Wednesday night on mid slopes and ridges.

For the remainder of the weekend, high pressure becomes
reestablished with high temperatures returning into the upper 90s
across western Nevada valleys with 80s for Sierra valleys. Typical
afternoon westerly winds will prevail each afternoon with some
enhanced winds possible by Saturday.

Looking into next week, there are some signs of an upper level
low developing off the West Coast which may act to weaken the
upper level ridge. This may act to finally draw some moisture
northward along the periphery of the ridge and introduce some
potential for precipitation. Couple this with some potential
tropical system development off of Mexico for additional moisture
and there may be some precipitation chances next week. However,
confidence is low at this time due the inherent uncertainties in
predicting both closed low and tropical systems. Fuentes

Aviation...

VFR conditions continue this week with a dry pattern remaining in
place. Some increase in mid and high clouds is expected as a weak
trough of low pressure and weak cool front move through Wednesday
night and Thursday. This should shift the winds to the north-
northeast but no precipitation is expected. Fuentes
