Area Forecast Discussion
National Weather Service Hanford CA
151 AM PDT Fri Aug 23 2019


.SYNOPSIS...
Temperatures will be near normal across the Central California 
Interior through today. A warming trend will take place this 
weekend, and highs will top out around 4-8 degrees above normal by
early next week. Dry weather continues, except for a slight 
chance of showers or thunderstorms near the Sierra crest by the 
middle of next week.

&&

.DISCUSSION...
Area of low pressure over the Northern Rockies and its associated
trough is diving into the Great Basin as depicted on water vapor
satellite. Meanwhile a ridge of high pressure is pushing southeast
into California and this feature will be the main weather
influence for the next several days as temperatures edge back over
the century mark in lower elevations. The ridge of high pressure
is progged to remain in place over the area through the weekend
and into the middle of next week.

Dry weather will continue, however forecast models indicate a weak
trough of low pressure will move into the coast on Wednesday and
with slightly cooler temperatures aloft (increased instability) a
few thunderstorms may form over the Sierra crest during this
period. Models then strengthen the ridge Thursday through the end
of the week. All in all continued hot and dry.
