High pressure builds along the West Coast this weekend,
strengthening and shifting inland by the early part of next week.
This will bring dry conditions with near average temperatures this
weekend warming to above average on Monday. Winds will mainly be
light Sunday through Wednesday with breezy afternoon conditions
returning for the end of next week.
A strong ridge of high pressure off the California coast builds
over northeast California and western Nevada this weekend, with
the ridge axis settling directly over the region on Monday.
Through Sunday night, temperatures will remain around average with
mild afternoons and cool to chilly mornings. Daytime highs will be
restrained some through Sunday as northeast to east flow in the
low to mid levels holds down the mixing potential in valleys. On
Monday, the east flow ceases under the ridge axis so mixing should
improve with high temperatures jumping to about 7-10 degrees above
.LONG TERM...Tuesday through Friday...
Few changes made to the long term as the ridge slowly breaks down
into late week. While the forecast remains dry for now, one thing to
watch will be a weak upper low working its way northward from Baja.
Currently, the models have it moving into extreme southern Nevada
then northeast. This would just bring a few clouds to areas south of
Highway 50. However, it will have quite a bit of moisture with it so
if it continues to trend closer, a few showers and thunderstorms may
need to be added to southern areas. Added ghost pops for now.
Aside from that, there will be a slow cooldown from Tuesday onward
as the ridge breaks down. Highs 10 to 15 degrees above average will
cool close to normal by Friday as a deep trough moves into the
Pacific Northwest. As the trough nears Friday, southwest winds will
increase with breezy conditions likely. Into next weekend, how the
trough continues to affect the Sierra and Western Nevada remains in
question. It could become quite cool and damp, or keep temps closer
to average. Wallmann
Dry, VFR conditions with light NE winds near the surface through the
weekend. Light wind conditions will continue through Wednesday with
some SW winds beginning Thursday and possibly stronger Friday into
next weekend. Wallmann
