Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
351 PM PDT WED MAY 25 2016

Scattered showers and thunderstorms will continue this afternoon and
evening over the Sierra Nevada and Kern County mountains. A gradual
warming trend for the end of this week until another weak system
moves in this weekend keeping temperatures cooler than normal and
increasing chances for precipitation...especially over the higher
elevations of the Sierra. Beginning Monday...high pressure will
bring warmer temperatures and clearing skies.


Southward moving clouds and showers have persisted over the
southern Sierra Nevada most of the day with a few embedded
thunderstorms developing after Noon with the daytime heating this
afternoon. This activity is from the moisture from the northeast
wrapping around a low pressure system currently located over
southeast California. With lack of any significant shearing any
thunderstorms that develop are expected to remain somewhat tame.
As nightfall approaches thunderstorm activity should be reduced.
The aforementioned low will continue moving eastward out of the
region allowing a northerly flow to entrench over the majority of
California ahead of ridging in place over the east Pacific. Breezy
conditions will be possible with the northerly flow...especially
through the Kern County mountain passes. Weak ridging will move
into the region beginning Friday which will bring a short lived
warming and drying trend to central CA interior.

A weak trough will move southward into the region on Saturday
bringing a return to cooler than normal temperatures and an
increase in precipitation chances for the higher elevations of the
Sierra through the weekend. A few showers would not be out of the
question over San Joaquin Valley locations with the synoptic
lifting as the trough moves through. Beginning Monday the Pacific
ridging will begin to move east over the west coast again bringing
a warming and drying trend. High temperatures in the mid 90s will
be possible by Tuesday through a majority of next week until
another longwave trough approaches the region by the end of next
