Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
405 AM PDT SUN JUL 24 2016

.SYNOPSIS...
A ridge of high pressure will provide the Central California
Interior with mostly clear skies and above average temperatures.
These conditions will persist over the region for most of the coming
week as the ridge of high pressure is expected to remain over the
area.

&&

.DISCUSSION...A flat but strong upper ridge continues to dominate
the southern portion of the country. The 594 DM ridge extends to
southern California with a weak trough entering northern CA.
Above normal temperatures will persist over the district with
widespread triple digit highs across lower elevations throughout
the upcoming week. The ridge expands over northern California by
midweek for the peak in the heat then little change to end the week.
While several degrees above normal, record setting temperatures
are currently not expected. But precautions should be taken when
dealing with this prolonged period of high heat. Medium range
models show a trough moving over the Pacific Northwest next weekend
for some weakening of the ridge and thus a modest cooling trend.

A dry air mass will continue to provide sunny skies through early
this week. But models have been indicating some monsoonal moisture
moving up into southern California by Monday and gradually spreading
northward through the week. There may be enough moisture for some
afternoon cumulus development over the mountains by Wednesday. By
Friday, moisture may be sufficient for afternoon/evening showers
and thunderstorms in the mountains and desert, and a slight chance
has been introduced through Sunday.

&&

.FIRE WEATHER...
A dry airmass will persist over the region for the next several days.
This will result in single digit humidity across the mountains and
desert areas of Kern County for as much as 4 to 8 hours each day
through Monday. Overnight humidity recovery will be poor (20 to 40
percent)in these areas. In addition, winds will be gusty through and
below the passes and canyons in Kern County. Gusts to 25 mph are
expected in the normally windy locations again this evening. Winds
are expected to diminish early this week. These conditions along
with hot temperatures and very dry fuels will create elevated fire
danger this weekend, though red flag conditions are not expected.

&&

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

&&

.AIR QUALITY ISSUES...
On Sunday July 24 2016... Unhealthy for sensitive groups in
Fresno... Kern... Kings... Madera and Tulare Counties and Sequoia
National Park and Forest.
