.DISCUSSION...A large upper low off the PAC NW coast continues
to pull pacific moisture into central California. The
atmospheric river which brought heavy rainfall to much of
northern California between Wednesday and Friday weakened by
the time it reached our area on Friday evening. Rainfall totals
across our area were nowhere near the amounts received in
northern California, but the higher Sierra Nevada and adjacent
foothills north of Fresno COunty generally picked up between
0.75 and 1.5 inches of liquid precipitation with up to near 2
inches at some stations near Yosemite Park. Much of the San
Joaquin Valley from Fresno northward picked up between 0.5 and
0.75 inches of rainfall while amounts were lower further
southward with many stations in Kings and Tulare County picking
up between a tenth of an inch and half an inch of rainfall
while much of Kern County only picked up a tenth of an inch or
less. Satellite imagery is showing a very impressive 120+ KT
250 mb jet stream out of the southwest pushing across our area
and radar imagery is showing some light upslope precipitation
continuing in the mountains.

The ensembles continue their good run to run consistency at
maintaining the strong upper low off the PAC NW coast through
Monday then move the this feature eastward across the PAC NW on
Tuesday. The NBM has been trending stronger with a system being
pulled up by the large trough moving through central CA on
Monday and Tuesday bringing another round of moderate to heavy
precipitation to our area.

Probability for 0.50 inches for selected cities on Monday:

Mariposa 85%
Oakhurst 80%
Merced: 65%
Madera: 75%
Fresno: 75%
Visalia: 60%
Coalinga: 60%
Lemoore: 55%
Hanford: 60%
Porterville: 60%
Bakersfield: 45%

Probability for 0.50 inches for selected cities on Tuesday:

Mariposa 96%
Oakhurst 96%
Merced: 80%
Madera: 75%
Fresno: 90%
Visalia: 75%
Coalinga: 65%
Lemoore: 70%
Hanford: 75%
Porterville: 75%
Bakersfield: 55%

This system will bring another round of snow to the SIerra
Nevada although snow levels have been trending upward with it
as well. Snow levels are expected to be around 6000 feet in
Yosemite Park and near 8000 feet along the Tulare/Kern County
border on Monday afternoon rising by 1000 to 1500 feet by
Tuesday. A Winter Storm Warning remains in effect for the Sierra
Nevada above 6500 feet through 400 pm PST Tuesday.

Slightly cooler and showery weather will prevail on Wednesday as
this system moves to the east of our area. High pressure is
progged to nudge into CA by Thanksgiving Day which will bring a
drying trend to our area before a weak southern stream system
undercuts the ridge and brings a chance of some light
precipitation into our area by the end of the week.
