A weak weather disturbance will drop south through California
tonight and Monday bringing a chance of precipitation to the
district. A warming and drying trend will then take place between
Tuesday and next weekend.
A weak disturbance moved south along the California coast
overnight and brought a dusting of snow across the mountains of
Kern County and light rain to the desert areas early this morning.
This system quickly moved into southern California with just some
lingering clouds over the region this afternoon. Another low
pressure system is located near Portland Oregon this afternoon. It
will move south overnight, taking a more inland track than last
nights system, with a difluent flow helping to bring a better
chance of precipitation over central California tonight and
Monday. Precipitation amounts will still be rather light, with
only a few hundredths of an inch in the San Joaquin Valley. In the
Sierra, precipitation will be in the form of snow with 1-4 inches
near Yosemite to an inch or less south of Kings Canyon. Snow
levels will be between 3000 and 3500 feet by early Monday, so the
foothills could see a few snow showers as well. In the mountains
of Kern County, snow levels will remain above 4500 feet with a
dusting of snow possible Monday morning.
A few showers will continue over the mountains Monday night as the
trough exits the region with a drier northerly flow over the
region Tuesday. Models are still indicating a dry period Wednesday
through Saturday with high pressure along the west coast. However,
the models are indicating another trough moving across the Pacific
Northwest Saturday with potential for it to drop far enough south
to bring clouds and maybe some light precipitation down to about
Yosemite Saturday night into Sunday morning. It looks like it
moves through quickly with the ridge rebuilding by Sunday night.
For now, the forecast remains dry for next Sunday and will watch
the pattern evolve.
