Area Forecast Discussion

135 PM PST Sat Mar 6 2021
.SYNOPSIS...Cooler today and tomorrow in the wake of the cold
front that passed through the area this morning. Dry southwesterly
flow will prevail for the next couple of days before a slow moving
system brings cooler, unsettled weather to the forecast area next
Tuesday through Thursday.

.DISCUSSION...
A weak cold front came through the region this morning that
lead to isolated light showers along with breezy conditions along
the Coastal Range. Latest satellite imagery shows some cloud
cover banked up across the southwest side of the San Joaquin
Valley, which will dissipate throughout the day. Breezy conditions
can be expected in the Mojave Desert today due to an appreciable
pressure gradient, with the HREF ensemble mean showing wind gusts
around 45 mph this afternoon through tonight. Have issued a wind
advisory from 3 PM this afternoon through 2 AM Sunday through and
below the Kern County Mountain passes accordingly. Thereafter, a
low amplitude disturbance embedded in the southwesterly flow will
bring cloud cover to the area again tomorrow, but not enough
moisture or lift to generate precip.
Calm weather for most of the day Monday as a trough from the Gulf
of Alaska slowly dips to the south. As the trough digs further
south Tuesday, showers are forecast begin impacting the northern
portion of the CWA. WPC 500 mb clustering has continuously showed
a slower, more offshore trend to this trough, which favors lower
QPF across the forecast area Tuesday. By Wednesday, the cold core
aloft will swing eastward giving the San Joaquin Valley enough
instability to support a thunderstorm or two through the
afternoon. Both the Euro and GFS ensemble means are showing the
trough exit the area Thursday, with the EPS being the slower
solution. So some unsettled weather remains possible for Thursday.
By this Friday, the general consensus is for ridging to redevelop
across the Eastern Pacific, which should shunt precip chances
over the weekend.
