Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
234 AM PDT Wed Sep 19 2018

.SYNOPSIS...
Dry weather will persist through at least Tuesday. Strong, gusty
west to northwest winds are expected in portions of the Kern
County mountains and desert this afternoon into early tonight.
Temperatures today will be near normal for this time of year,
followed by a warming trend Thursday and Friday.

&&

.DISCUSSION...
A mid to upper-level trough of low pressure will move eastward
through Central California this morning, before progressing into
Nevada this afternoon. This trough of low pressure will continue
to proceed eastward into Utah tonight. Strong, gusty west to
northwest winds are likely in portions of the Kern County
mountains and desert this afternoon into early tonight. In fact,
wind gusts near 50 mph are conceivable in parts of that area this
evening into early tonight. A Wind Advisory will not be issued at
this time due to the localized, brief nature of these wind gusts.
A mid to upper-level trough of low pressure will be located just
offshore of the Pacific Northwest Thursday through Saturday. A
weak ridge aloft will build into Southern California Thursday
through Saturday. This will result in a warming trend for the San
Joaquin Valley Thursday through at least Friday.

An area of low pressure should develop in the base of the
aforementioned mid to upper-level trough of low pressure Saturday
night offshore of Northern California. An area of high pressure
aloft will move eastward Sunday, positioning itself offshore of
British Columbia. This will set the stage of the development of a
Rex Block Sunday night. This Rex Block should remain in place
Monday through at least Tuesday. As a result, very little change
in temperatures are expected from late this weekend into early
next week. Dry weather will persist through at least Tuesday.
