Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
258 AM PDT Thu Apr 27 2017

Breezy conditions will continue across the region today and
Friday. Lighter winds, warming temperatures and dry weather will
then prevail this weekend into early next week as high pressure
strengthens over the region.


A ridge of high pressure remains over the eastern Pacific with a
broad trough of low pressure over much of the central U.S.
Shortwave energy continues to move across the Pacific Northwest
and drop into the Great Basin. This is resulting in continued
breezy condition across central California. Winds were strongest
across the Kern County mountains and desert Wednesday afternoon
and evening. Although winds have decreased slightly overnight, a
few places continue to gust above 45 mph. The winds may decrease
a bit more this morning, but will increase again this afternoon as
850mb winds increase to around 40kts. Thus the wind advisory for
the Kern mountains and desert has been extended until 5 AM Friday.

The northwest winds are also causing upslope clouds in the Kern
County mountains this morning. The low clouds may cause reduced
visibility at times through the morning hours. The clouds are
expected to gradually clear through the day.

It will also expect be breezy in the San Joaquin Valley today
with northwest winds 10-20 mph gusting as high as 30 mph at times
this afternoon and evening. As shortwave energy continues to drop
through the Great Basin on Friday, expect winds to be gusty in
the Valley again Friday and Friday evening. Winds will also be
breezy in the Kern mountains and desert Friday, but with the flow
aloft becoming more northerly, it looks like winds will stay
below advisory levels. Winds will drop off significantly on
Saturday as the ridge of high pressure begins to push eastward.

As the ridge pushes inland this weekend into the early part of
next week, a warming and drying trend will take place across the
region and temperatures will rise to above seasonal normals. The
medium range models are in good agreement with the ridge remaining
over the western CONUS for much of next week which improves
confidence that warm temperatures and dry conditions will
prevail over the area.


Local MVFR and isolated mountain obscuring IFR in low clouds in the
Southern Sierra Nevada until 20Z Thursday and in the Kern County
Mountains until 12Z Friday. Otherwise, VFR conditions will prevail
across the central CA interior during the next 24 hours.





The level of certainty for days 1 and 2 is high.
