Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
413 AM PDT Tue Jun 27 2017

.SYNOPSIS...Temperatures will continue trend cooler today then a
slow warming trend will take place Wednesday through Saturday. Dry
conditions will also continue into the weekend. Coastal pass and
Kern County Mountain passes and desert areas could see breezy to
gusty winds once again today and Wednesday.

&&

.DISCUSSION...An upper trough which moved through CA yday
resulted in cooler daytime temperatures across our area as many
locations which had highs in the triple digits for the previous 8
or 9 days remained below the century mark on Monday. Some weak
shortwaves moving though the PAC NW will re-enforce the cooler
airmass and temperatures will be closer to seasonal normals today
as a result. WV imagery is indicating that this airmass is dry at
the mid and upper levels and with a westerly flow prevailing our
area will remain mainly clear and free of precipitation. Increased
surface p-grads have resulted in increased winds over the Kern
County Mountains and Deserts on Monday, but winds have slowly
decreased overnight.

Even with the ongoing cooling trend taking place over our area,
high water levels continue in the Kings River with large outflow
from Pine Flat Dam and a Flood Warning remains in effect for
portions of Northern Kings, Northwest Tulare and Central Fresno
Counties as a result. Waterways will continue to run cold, deep,
fast and dangerous as they continue to be fed by melting snow.

WRF indicating that upper ridging is progged to rebuild off the
coast on Wednesday and Thursday. This will result in an upward
trend in temperatures each day as heights and thicknesses rise.

The medium range models build the ridge inland by the end of the
week which will produce continued rises in heights and
thicknesses over our area and portions on the San Joaquin Valley
will have highs in the triple digits this weekend as a result.
However a return of the record heat that was experienced last
week is not anticiapted. There are no significant chances for
precipitation throughout the period as RH progs are indicating
moisture remaining limited.

&&

.AVIATION...VFR conditions will prevail across the central CA
interior during the next 24 hours.

&&

.AIR QUALITY ISSUES...None.
