High Wind in California, June 9, 2018

Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
340 AM PDT Sat Jun 9 2018

.SYNOPSIS...
Dry weather will continue through at least the next seven days.
Over the weekend winds will increase as a system moves onshore
across the northern portion of the state. Otherwise, lighter winds
expected across the area with a warming trend through mid week.

&&

.DISCUSSION...
A change in the weather pattern is starting to take place over the
West Coast this morning. Satellite IR imagery along with surface
frontal analysis shows a cold front pushing across the Pacific
Northwest and Northern California. While precipitation is not
expected over the Central California Interior today, precipitation
is noted over extreme Northern California. Based on how weak the
area of energy will be pushing through Central California, will
not mention precipitation, but will start a cooling trend along
with strong surface winds during the day this Saturday.

Model confidence remains high on the prognosis of having the
effects of this disturbace, which is dropping down from the Gulf
of Alaska, provide the area with cooling and winds. Therefore,
what warming was seen on Friday will start to be lost Today as the
disturbance pushes through the Pacific Northwest and Northern
California. Again, while most of the energy from this disturbace
will remain too far north, its influence will be felt by changes
in temperatures and winds over Central California. Models continue
to prog a drop in temperatures by a few degrees this Saturday and
as much as 10 degrees below climatology by Sunday afternoon. The
push of cool air into the region will also generate a strong
pressure gradient, already at 11mb as of 3 AM PDT, from KSFO to
KLAS that could produce strong winds (and possible blowing dust)
over the Kern County Mountains and Deserts by this afternoon. As
stated above, issued a wind advisory for the mentioned areas as
models prog border-line potential surface pressure gradients that
could resolute in strong afternoon gusty winds.

Models also show the disturbace over the weekend as a progressive
one which then ejects from the region later on Sunday. While in
its wake cooler air will filter into the district, the disturbace
continues to show signs of lifting toward the Northern Rockies by
Sunday night. Therefore, the cooling trend will be short-lived as
warming begins again on Monday. This trend may also be short-lived
as yet another disturbace attempts to enter the region later next
week. In the meanwhile, a short-wave ridge will cross the region
early in the week. Upper air analysis also shows an area of high
pressure near the four-corners area early next week. However, the
stronger westerlies may not allow for the formation of a good
southeasterly flow aloft. Without the southeasterly flow pattern,
the region will see a lack of a significant moisture source for
possible precipitation. Therefore, the region remains dry during
the forecast period. Models are now trending toward the
development of yet another disturbace during the latter half of
next week. This solution may result on more cooling and winds as
the roller-coaster ride continues.
