National Weather Service San Joaquin Valley - Hanford California
301 am PST Sat Mar 8 2014
dry and warm conditions expected through the weekend as a weak
high pressure ridge builds into the region. By Monday a passing
system will bring gusty winds to the Westside valley and Kern
County mountains and desert...as well as a chance of precipitation
in areas from Fresno County northward.
some high clouds are spilling over the western Continental U.S. Upper
ridge...otherwise skies are mainly clear across central California
this morning with just some patchy light valley fog. Dry and warm
conditions will continue for the next couple of days as the ridge
strengthens over the region...with highs as much as 10 to 15
degrees above climatology. Still looking for some highs around 80 degrees
in the warmer South Valley locations Sunday.
Models remain consistent in bringing another shortwave trough
across northern California into the Great Basin. The timing and
trajectory would bring a chance for precipitation to areas mainly
from Fresno County northward begining late Sunday through Monday.
Quantitative precipitation forecast amounts should be modest as little moisture is prognosticated to
accompany this system. Increasing onshore surface pressure
gradients and upper level jet energy with the passing trough will
also return gusty winds to the Kern County mountains and desert
areas as well as the west side of the valley by Monday.
Rebuilding high pressure overhead along with a redeveloping
offshore flow will return dry and warming conditions by the middle
of next week...with temperatures warming again to several degrees
above seasonal norms.
areas of MVFR visibilities and local IFR visibilities in mist over
the central and south San Joaquin Valley through 18z today.
Otherwise...VFR conditions will prevail throughout the central California
interior during the next 24 hours.
