through Thursday A disturbance aloft will move across the

.DISCUSSION...
Large picture showing the omega blocking high pressure system
persisting over the eastern Pacific. Eastern upper low of the
system continues to churn over western Arizona and will only very
slowly lift to the north on Wednesday. At the surface, cold
airmass remains in place along with considerable stratus and low
stratocumulus. Models show much of this cloudiness continuing into
Wednesday. Brisk east winds, especially just west of mountains,
will continue through tonight and likely into Wednesday, but
should remain below advisory criteria in these areas. The upper
low will rotate a short wave across the CWA this afternoon, so low
POPs in place for this. Sacramento Mountains could see some light
snow accumulations through tonight, mainly above 8000 ft. Some
dry slotting into the southern zones Wednesday behind the
shortwave so limited POPs to the northern zones. Models have been
showing tropical moisture tap moving up over the eastern zones
Wednesday night and Thursday, but have backed off some from
previous runs. Will still increase POPs some for this period in
the east though.

Friday and Saturday...looks like maybe a brief break in the
chilly weather, with a return back to early fall type weather.
Upper low is now east of the area as we watch a another developing
upper low off the southern California coast. This should allow
drier mid/high level flow and some sunshine for the area.
Temperatures will warm nicely, around 20 degrees warmer than
today. However this will still be around 10 degrees below normal.

Sunday into early next week...series of upper lows off the
California coast march toward the area Sunday afternoon and Monday
afternoon, bringing POPs back to the area.

just a gradual warm-up expected toward Friday/Saturday. Temperatures

above 40-50 percent all week long. A disturbance moving east
acrossthe fire zones today could bring a few light rain showers,
with some light snow possible over the Sacramento Mountain zones.
Winds will remain out of the east to northeast at 10 to 20 mph,
with local gusts to 35 mph before decreasing. Mixing heights will
remain fairly low which will keep vent rates poor to fair.
