.SYNOPSIS...
A trough of low pressure will impact the the region through and
Thursday with breezy to gusty winds. Light precipitation will be
possible in the higher elevations of the Sierra especially near
Yosemite tonight through Thursday. Below normal temperatures will
continue through at least Thursday. A warming trend will begin
Friday.

.DISCUSSION...
A trough of low pressure continues to move through the region this
morning with breezy conditions in the San Joaquin Valley and the
Kern County mountains and desert. Radar indicates a few light
showers continuing in the Sierra Nevada and these scattered light
showers will continue through the day today. The trough will exit
the region tonight with a weak ridge of high pressure Friday
through the weekend. Temperatures today will be 10-15 degrees
below normal, with highs in the San Joaquin Valley mainly in the
upper 70s. Temperatures will begin to warm Friday, warming to near
normal Saturday and Sunday.

Another trough of low pressure will drop into Oregon and northern
California Sunday night. Models have not been in good agreement on
the track of this system the past few runs, but have now come
into better agreement that the low will drop down the east side
of the Sierra and then into western Arizona by Tuesday night
before lifting northeast by Thursday. This will bring a slight
dip in temperatures Monday with a slight chance of showers over
the Sierra Nevada. A few showers may linger over the southern
Sierra and Kern County mountains and desert areas Tuesday and
possibly Wednesday before the low lifts out. Otherwise, the CWFA
will remain dry with temperatures remaining near seasonal normals
next week.
