High pressure will provide dry weather and seasonable temperatures
for the rest of the weekend. Weak weather system will provide
precipitation chances Monday and Tuesday.
Ridge of high pressure will remain over the region through the
weekend. Temperatures on Sunday will be similar todays. Some
patches of fog may form once again in some of the mountain valleys
of Plumas County late tonight and Sunday morning.
A very weak weather system will move into the region on Monday
and Monday night. The system may bring a third of an inch or less
for the mountains and less than that for the valley. The system
will exit the region late Monday night and Tuesday morning. Breezy
conditions can be expected as the system moves through. Snow
accumulation will be minimal but the higher elevations near pass
level may be able to get a little bit.
Zonal flow aloft over the region for Tuesday with light northerly
winds. Cooler air will remain over the area to keep temperatures
in the lower to mid 70s for another day for the valley to the 50s
for the mountains. Some high cloudiness should be over the area
.Extended Discussion (Wednesday through Saturday)
For the most part, benign weather is expected through the extended
period as a weak ridge builds into Southern California. The latest
model runs have backed off on the possibility of precipitation
along the Coastal Range and Shasta County late next week,
preferring to keep it immediately along the far NW coast and
northward. Otherwise, expect temperatures to be around to slightly
above normal through the extended period under the influence of
weak high pressure.
VFR conditions and mainly light winds continue the next 24 hours.
