Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
215 PM PDT Thu Mar 30 2017

A fast moving storm system dropped into the Great Basin today.
This storm brought windy conditions to the area along with some
showers, mainly over the mountains. High pressure will return for
more springlike conditions during the weekend into early next


A change was ushered into the district overnight as clouds, winds
and spotty showers occurred today. While much of the Central
California Interior has cleared out today, a few lingering showers
and cloud cover continues over the Sierra Nevada and much of Kern
County. At this point, winds have become the main concern for
today as surface wind speeds reach 30 mph with occasional gusts
to near 40 mph. Over the higher terrain of the Sierra Nevada and
the Tehachapi Range, winds have been able to gusts up to 60 mph.
A wind advisory remains in effect for the valley and a Wind
warning for the Tehachapi Range until near 11 PM PDT this evening.

Model still predicting a short break in the weather over the
weekend as a short-wave ridge shifts through the region. While
Friday morning may see a continuation of breezy winds and a few
clouds over the Sierra Crest, the overall trend is for a short
duration warm-up and sunshine. The ridge pattern will be tilted
(or flat) which will support the introduction of another trof into
the region early next week. Warming that may occur over the region
on Friday and Saturday will stop by Sunday as the region goes into
a cooling trend. Models showing higher confidence in breaking down
the ridge by the end of the weekend as another storm moves into
the region.

The next storm will begin moving into the region by late Sunday
night into early Monday morning. The transitory ridge will allow
another trof to enter the region early next week. While more
uncertainty exist with the second storm system, clouds and winds
could reach the Central California Interior on around Monday.
Higher confidence level exist with the timing of this storm then
with the amplitude. Because of the higher confidence in timing,
will expect another ridge pattern over the region toward the
middle of next week.


In the San Joaquin Valley, Windy conditions continue until 06Z
Friday. In the Southern Sierra Nevada and adjacent foothills,
scattered showers until 06z Friday with local IFR conditions and
mountain obscuration over the sierra high country. In the
