Area Forecast Discussion

.SYNOPSIS...
Showers and isolated thunderstorms possible across higher
elevations through Wednesday, although a few showers may linger on
Thursday and Friday. Warmer and mainly dry conditions by this
weekend.

&&

.DISCUSSION...
Another round of showers and isolated thunderstorms for mainly
higher elevations today as closed low drifts toward SoCal.
Coverage should be greater than yesterday with more widespread
activity if latest hi-res guidance pans out. A few of these could
make it down to the Valley as well but tough to pinpoint exactly
where. Snow should remain above pass levels, although a few inches
could impact the higher passes south of Lake Tahoe. Trough
continues to shift east on Wednesday with diurnal showers and
thunderstorms possible again across higher elevations. Coverage
should be less extensive than today. A few showers may linger for
Thursday and Friday, but will generally be south of Lake Tahoe. As
trough retreats, temperatures will warm to near normal for end of
the work week. Dry weather expected elsewhere as we head toward
the holiday weekend. Breezy northerly winds may develop on Friday.

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)
A broad upper level trough will remain across the intermountain
West through much of the extended period. Weak shortwaves will
likely rotate through the trough, bringing chances of showers
mainly across the Sierra. The timing of these shortwaves isn`t
handled well right now, and so we`ve largely included slight
chance wording through most of the period. Even with the presence
of the upper trough, temperatures are expected to be near to above
normal. Breezy north winds may be possible across the Valley,
again dependent on timing of shortwave troughs.

.AVIATION...
VFR conditions for the next 24 hours with relatively light south
to west winds. The upper level trough continues to linger over
Northern California and will result in SCT 4-8 kft cumulus in the
valley...there could be isolated MVFR conditions if thunderstorms
pop up in the valley this afternoon. MVFR conditions still
possible over the mountains in scattered showers through
Wednesday.

.STO Watches/Warnings/Advisories...
None.
