.DISCUSSION...

Expect little change in our dry weather pattern for the next
several days. Our resident high pressure ridge centered over
northern CA/NV will stay put through midweek, then retreat to off
the Pacific NW coast by late week but return inland by the
weekend.

In general, the weather that has been occurring for the past few
days will be stuck on repeat for the remainder of this week, with
valley inversions keeping hazy conditions with some reductions in
air quality especially around urban areas. The dry air mass and
limited cloud cover will keep typically chilly nights for mid-
January. For areas not affected by freezing fog, temperatures
managed to edge upward a few degrees Monday, and another modest
rise is expected today through Wednesday. Then for the remainder
of the week into the start of the weekend, highs stabilize with
most western NV and Sierra valleys settling in the lower-mid 50s,
although a few sites above the inversion-trapped valley floors
could have a peek at 60 degrees. Unfortunately for those more
persistent foggy areas, most notably around Mono Lake, highs are
unlikely to reach 30 degrees with the fog producing poor
visibility and patchy slick conditions on paved surfaces. Some
shores of Mono Lake may see a short period of clearing each
afternoon, followed by fog returning after sunset. Smaller scale
shallow fog could also develop near other lakes and sources of
standing water each night/morning this week.

Winds remain light for lower elevations, while for Sierra ridges,
a steady east flow will keep gusts in the 20-35 mph range for the
next few days. A slight tightening of the 700 mb gradient could
bring short periods of 40+ mph ridge gusts tonight-Wednesday and
again around Thursday night.

For the late weekend into early next week, the high pressure
ridge shows some potential weakening which may help reduce the
strength of the valley inversions. This could bring highs near 60
degrees to more sites around the region, and possibly help
disperse some of the freezing fog around Mono Lake, although there
remains some questions as to whether enough mixing will occur. As
for when we might see precip return to the region, longer range
guidance brings signals of more storm activity after January
21st. MJD

.AVIATION...

Patchy FZFG will continue through this morning at KTRK with
IFR/LIFR conditions at times until around 17Z, and likely return
between 08-17Z for tonight/Wednesday AM. Some of this fog could
be shallow and only partially obscure the airport`s runways.

Otherwise, VFR conditions and light surface breezes prevail today
and through much of this week at the main terminals, with minor
slantwise visibility reductions due to haze around the W NV
terminals.

E/NE FL100 wind gusts will ease back to below 30 kt for much of
today, but then increase to 30-40 kt again over the Sierra crest
tonight through Wednesday morning, leading to areas of turbulence
for flights crossing the Sierra. MJD
