.DISCUSSION...

Shower and thunderstorm activity continues to wind down as noted on
latest radar obs, with only a few lingering showers in Mono County
as of 2 PM PDT. This area will be the focus for additional showers
and perhaps isolated thunderstorms through the midafternoon.
Light snow showers also are possible along the higher peaks of the
White Mountains and Sierra in far S Mono County before showers
taper off by the late afternoon.

The upper low responsible for today`s cool and showery weather will
continue to track to the southeast, leaving north to northeast
breezes in its wake. Winds will become gusty along and west of the
Sierra crest tonight into early Tuesday morning with NE gusts around
40-50 mph. Tuesday morning is shaping up to be a chilly one for
colder Sierra valleys as temperatures fall near or below
freezing. Higher Sierra elevations will also be quite brisk early
Tuesday morning as the aforementioned gusty NE winds make it feel
colder than it really is. Be sure to bundle up if traveling or
recreating in these areas Tuesday morning!

High pressure begins to overspread the region after today, keeping
the rest of the week and weekend dry. Temperatures will sharply
increase through midweek, resulting in upper 70 to 80 degree highs
from mid to late week.

.AVIATION...

Isolated showers may occasionally lower CIGS/VIS to MVFR
conditions at KMMH through 23z, otherwise VFR conditions and light
north breezes prevail today. E-NE FL100 winds will increase to
25-30 kts overnight, which may lead to periods of mountain wave
turbulence along and west of the Sierra crest between 03Z and 12Z.
