Area Forecast Discussion UPDATE
National Weather Service Hanford CA
513 PM PDT Wed Jun 29 2022

...Update to Air Quality Issues Section...

.SYNOPSIS...
A steady cooling trend will continue through the holiday weekend
with temperatures falling to several degrees below normal on
Sunday and Monday. Afternoon and evening breezes will develop each
day with higher gusts in the mountain passes and desert in
eastern Kern County. Dry weather will prevail for at least the
next seven days.

.DISCUSSION...
The high pressure ridge which has been producing dry and very hot
conditions over our region is being weakened by a modest
shortwave trough along the west coast. 24 hr temperature trends
are currently running down around 2-4 degrees, while our skies
remain mainly sunny across the area.

Model solutions maintain the troughiness along the coast for the
next several days, deepening it most significantly during the
holiday weekend as a developing low pressure system tracks into
the Pacific Northwest coast by Sunday. The result of this
evolving pattern will be a significant cooling trend for us, with
periods of breezy winds through the Independence Day holiday.
Afternoon high temperatures will steadily decrease, down to
around normal values by Friday and Saturday, and a few to several
degrees below normal by Sunday and Monday. By Monday, blended
model guidance shows around 60-80 percent probabilities that high
temperatures in the San Joaquin Valley will remain below 90
degrees. Although we will be cooler through the holiday weekend,
no precipitation is associated with the lowering temperatures.


After the holiday cooldown, ensemble solutions rebuild the ridge
over the western states and we will gradually begin a warming
trend for next week. High temperatures however are still expected
to be a degree or so below normal for next Wednesday. Dry
conditions also continue next week.
