Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
319 AM PDT Thu Oct 19 2017

.SYNOPSIS...
Temperatures will trend much cooler through Friday as a storm
system moves over northern California. This system will bring a
chance for light precipitation Thursday night and Friday along
with an increase in winds. Dry weather will return later this
weekend with a warming trend into early next week.

&&

.DISCUSSION...
Temperatures will cool a few degrees today in advance of a trough
of low pressure dropping out of the Gulf of Alaska. Models are
in better agreement with the timing and position of the trough as
it moves to the northwest US coast this afternoon and then inland
late tonight and early Friday.

Models continue to keep the main energy and moisture to the north
of our area, but we will still see some precipitation across
central California, especially near Yosemite. The cold front will
approach Yosemite late tonight and move southward into Kern
County by Friday morning. The greatest amount of precipitation
will be near Yosemite where a quarter to as much as half an inch
is expected and in the upslope areas of Kern County where one to
two tenths of an inch of rain is possible. In between, just a few
hundreths of an inch is expected as the frontal band moves south
early Friday morning. Snow levels initially above 10000 ft
Thursday evening will fall to near 8500 ft in the Sierra by 12Z
Friday. Snowfall amounts of 1 to 3 inches are possible in the
higher elevations of Yosemite, with less than an inch farther
south. This system moves through quickly, so by Friday afternoon,
should see just some lingering upslope showers in the Kern County
mountains.

A brief period of gusty winds could accompany the front as it
moves through early Friday. However, winds are expected to be a
bit stronger behind the front, mainly in the west side of the San
Joaquin Valley and in the Kern County mountains and desert.
Generally expect wind gusts up to 45 mph in the Kern County
mountains and desert areas, however, could see a few higher gusts
in the normally windier locations. The west side of the San
Joaquin Valley will see locally gusts of 20 to 30 mph.

Temperatures on Friday will be 10-15 degrees cooler than today,
and will be air behind the front will keep temperatures around 10
degrees below normal temperatures for mid October. However, these
cool temperatures will not remain for long. Models remain in good
agreement with high pressure strengthening over the region through
the weekend and into the middle of next week. This will bring dry
and warming conditions, with temperatures returning to around
normal by Sunday and 5-10 degrees above normal by Tuesday.

&&

.AVIATION...
Areas of MVFR visibilities due to smoke and haze will continue in
the San Joaquin Valley and across the adjacent Sierra Nevada and
foothills. An approaching cold front will spread precipitation from
north to south after 00Z Friday with areas of MVFR and local IFR
conditions with mountain obscurations. VFR conditions will prevail
in the Kern County desert.

&&

.AIR QUALITY ISSUES...
On Thursday October 19 2017... Unhealthy for sensitive groups in
Fresno... Kern... Kings and Tulare Counties.
