Synopsis... dry weather can be expected over the central California
interior for the next several days. Temperatures will average slightly
below normal for much of this week as onshore flow prevails. Gusty
winds can be expected in the Kern County mountains and desert each
afternoon and evening.
clear and dry tonight across the district. A weak disturbance off
the Southern California coast will move NE bringing high level
clouds to the Kern County area this afternoon then into the Central
Valley tonight. Expect a slight rise in temperatures today before
the next weather system pushes S over the Pacific northwest. A
leading shortwave will move through Oregon increasing the onshore
flow across north California. This will usher in a cool and breezy trend
across central California Wednesday. Additional short waves will follow
each day deepening a long wave trough across California. Surges of
cooler air with each wave will bring breezy gusty winds especailly
through the mountain passes along the west side of the San Joaquin
Valley and below the Kern County mountain passes each afternoon
and evening Wednesday through Friday. Below normal temperatures
will last several day into the weekend. The trough finally moves
east of the Sierra Saturday night allowing a warming trend for
next week. Little threat of precipitation for the week as models
do not forecast deep moisture reaching central California and maintain monsoon
moisture east of the Colorado River. Warm a dry trend for the
start of next week with models forecasting a surface high over the
Great Basin providing an offshore flow and a building ridge aloft
extending into California from the desert SW.
