Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
325 AM PDT Mon Oct 15 2018

.SYNOPSIS...
A disturbance moving into Southern California will help generate
strong easterly winds across much of the area. These strong
easterly winds are expected to blow across Central California
through at least this Monday evening. Afterward, dry conditions
are expected to continue with temperatures remaining at near
normal values.

&&

.DISCUSSION...
Strong winds impacting the Central California Interior this
morning as wind gusts reaching 50 mph affect the area. Reports of
fallen trees across the mountains have been given from several 
locations. Given the current wind speeds, a wind advisory is in 
effect until around sunrise for the region from Yosemite to Kings 
Canyon. While winds are also blowing across the Kern County 
Mountains, the wind advisory for that area will continue until 
around sunset this evening. In addition, because of the trajectory
of the associated disturbance producing the strong winds, the path
of the disturbance will introduce little moisture into the region.
Therefore, the disturbance will remain dry with winds the main
impact affecting Central California. Due to a blocking pattern
over the West Coast, little change will occur over the region as
easterly wind flow will continue for several days. 

The current disturbance associated with the strong winds is
progged to linger over the Desert Southwest as it become part of
an Omega Blocking pattern. While uncertainty exist on how the
pattern will evolve toward the middle of the week, will lean
toward keeping the center of the low near the four corners area
through early Thursday. This solution will place the axis of the
high pressure ridge just off the California coast and the district
under a north to northeasterly wind direction. By Friday, the
blocking pattern converts over to a Rex Block formation which may
allow for a northward surge of moisture into the region. At the
moment, will increase cloud cover for the latter part of the
forecast period (around Sunday - Monday) and wait until confidence
increases to introduce precipitation. Otherwise, will expect
temperatures at near normal values while a blocking pattern
dominates the area.

.AVIATION...
VFR conditions will prevail over the central California interior for 
at least the next 24 hours. Windy east winds across the Sierra
Nevada and Kern County Mountains with lcl sfc wnd gusting over 
40kts until 03Z Tuesday.
