Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
320 AM PDT Tue Apr 25 2017

.SYNOPSIS...
Dry weather and seasonable temperatures through the end of the
work week. Breezy conditions expected through the week.

&&

.DISCUSSION...
Upper level northwest flow remains firmly in place over
California as a ridge of high pressure resides over the eastern
Pacific with a broad trough of low pressure over much of the
central US. This pattern continues to bring seasonable
temperatures to central California as well as breezy conditions.
The strongest winds today were observed over the desert and Kern
county mountains, where wind gusts in excess of 55 mph were
reported. Winds are decreasing early this morning and will not be
as strong today as they were Monday.

Clouds are banked up against the mountains at the south end of the
San Joaquin Valley this morning and expect them to remain through
mid day before clearing. This may result in reduced visibility
through Tehachapi pass and over the Grapevine this morning.
Otherwise, expect some mid and high level clouds to move through
the region the today.

Little change in the upper level pattern through at least Friday
with seasonable temperatures and breezy conditions. Another
shortwave moving in the northwest flow will drop south through
the Great Basin on Wednesday. This will bring a slight chance of
showers over the Sierra north of Kings Canyon on Wednesday. This
will be followed by another impulse dropping south into the Great
Basin Thursday and Friday. This second system will bring an
increase in winds across the region Thursday and Friday with the
strongest winds likely occuring Friday afternoon and evening. In
fact, parts of the San Joaquin Valley could see northerly wind
gusts between 35 and 40 mph. We will continue to monitor this
closely over the next few days.

The ridge of high pressure over the eastern Pacific will begin to
build east over California this weekend into early next week.
This will result in a warming trend Saturday and Sunday, with
above normal temperatures Sunday and Monday.

&&

.AVIATION...
Mountain obscuration over the Tehachapi Mountains until 18z Tuesday.
Otherwise VFR conditions prevailing throughout the central CA
interior during the next 24 hours.
