.DISCUSSION...
Generally fair weather prevails today with mostly sunny skies and
light winds. A few showers and/or a stray thunderstorm over Mono
and Mineral counties are the exception this afternoon. This is a
result of the upper low that has descended towards the
SoCal/Vegas/western AZ area and allowing a transient upper high
pressure area to move in. The closeness of the low to the southern
portions of our region leads to those showers as there is
marginal instability and some residual moisture. However, chances
are low below 10%. Tomorrow, those chances expand to 10-30% mainly
for the Eastern Sierra and areas south of US-50 as the
Mono/Mineral area and vicinity end under the deformation zone due
to the approach of the next upper trough providing extra lift
from the diffluence aloft.
Widespread active weather returns on Sunday and through much of
next week. A broad longwave upper level trough descends from the
Gulf of Alaska between Sunday and Monday. The storm track will
remain over the region allowing at least two shortwaves passing
through by mid-week with the main cold front on Monday night into
Tuesday morning. There is potential for a third shortwave right
before the end of the work week, but models start to diverge by
this time, bringing more uncertainty.
Winds will start to increase on Sunday afternoon, especially over
mountain ridges and areas north of I-80. Then on Monday and
Tuesday we are expecting gusty winds areawide with gusts in the
30-40 mph range with a 60-90% chance of exceeding 30 mph both
days. Winds decrease by Wednesday. Periods of showers and isolated
thunderstorms are likely through Wednesday, especially over the
Sierra, where we have the best chances for precipitation. It is
also important to note that temperatures will be decreasing
through mid-week with Tuesday being the coldest day of the week.
Thus, snow levels come down from 12 kft to 9-10 kft by Tuesday
morning. So, the highest peaks may see some snow, how much, is
still tbd, but looking at light amounts below an inch per the
ensemble members of the GFS/ECMWF. Cooler temperatures also
prevail next week as previously stated with afternoon highs 5 to
20 degrees below average Mon-Wed. A slight warm up starts on
Wednesday, but the region remains around 5 degrees below average
by the end of the week.
