Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
323 AM PDT TUE JUL 26 2016

A ridge of high pressure will provide the Central California
Interior with mostly clear skies and above average temperatures
through the week. Isolated afternoon showers and thunderstorms
possible along the Sierra crest by Wednesday, possibly spreading
into the Kern County mountains and desert by the weekend.


Clear and dry conditions will continue across central California
today as a strong ridge of high pressure remains in control. The
ridge currently centered over the four corners region will drift
West to over Southern Nevada by midweek. High temperatures will
remain several degrees above normal with widespread triple digit
heat in the lower elevations, but are not expected to reach record

The models have been advertising a push of some monsoonal
moisture into California this week. Satellite water vapor imagery
shows it a little bit of moisture beginning to move over southern
California. The mid-level moisture will gradually spread northward
up the Sierra this week. Some afternoon cumulus will likely
develop over the Sierra Wednesday with possibly an isolated
thunderstorm over the high elevations by late in the afternoon. A
slight chance of thunderstorms continues over the Sierra Thursday.
Models had been indicating the monsoonal moisture moving into the
Kern County mountains and desert by Friday, but they have now
backed off on that idea. Thus have reduced the chance of
thunderstorms across Kern County Friday. Even though the moisture
doesn`t look very impressive for the weekend, have maintained the
slight chance of thunderstorms across the Sierra Nevada and Kern
County mountains and desert until we see how much moisture will
continue to move north.

The ridge will begin to weaken and drift east beginning Sunday as
a trough of low pressure moves toward the Pacific Northwest coast.
Models remain in good agreement with this trough gradually moving
inland to our north early next week. This will bring a return to a
drier southwest flow aloft, ending the chance of thunderstorms. It
will also allow temperatures to edge down a few degrees over the
weekend and into early next week, although triple digit
temperatures are still likely in the lower elevations.


VFR conditions can be expected through Central California for at
least the next 24 hours.
