.DISCUSSION...through Wednesday.

Low amplitude ridging holds through Thursday, transitioning to more
zonal flow on Friday. This keeps the weather quiet and warm, with
highs continuing to run 10-15 degrees above normal. Dry conditions
prevail as afternoon breezes generally stay in the 10-20 mph range.

Late Saturday through Monday, a plume of moisture is forecast to
impact the central and northern Sierra. The zonal nature of the flow
should result in most of the moisture/precipitation being
intercepted by the mountain range. PoPs in our portion of the Sierra
range from 20-50%, increasing with latitude. Meanwhile, the northern
Owens Valley and western Esmeralda County have 20-35% PoPs.
Precipitation in the valleys will likely be pretty light (75% chance
of less than 0.25"), while the Sierra is likely (75%) to remain
below 1.00". Snow levels stay at or above 9000 feet throughout most
or all of the precipitation, so concern of winter impacts is low.

Global ensembles continue to advertise a deep trough off the
California coast during the middle of next week. Southwesterly flow
ahead of the trough axis will draw up anomalous moisture into the
region. Barring a significant change in track, the mountains will
fare well precipitation-wise. Precipitation amounts in the valleys
will depend on the strength of the system and moisture trajectory.
Given the warm, southwesterly flow, not anticipating snow levels to
be that low, but locations above 7000 feet will certainly have the
potential of seeing winter impacts. Depending on the system`s
evolution and track, wind impacts may be on the table as well. All
this to say, keep an eye on the forecast over the coming days as
details become more clear and confidence increases.
