Summary A low pressure system is centered just to the northwest of San Francisco this morning. A much cooler air mass has moved in aloft. Freezing levels at this time yesterday were at about 14,000. This morning it’s at 11,000 feet. The marine layer along the coast has deepened to more than 3,000 feet and is having no problem pouring over the coastal mountains and into the valley. Temperatures this afternoon will drop to a good 10 degrees below average and 15 degrees below average Sunday. Highs Sunday will likely not reach the 80 degree mark on the valley floor. light showers will spread over the mountainous terrain of northern California and down the Sierra Nevada to perhaps Yosemite. The low will begin to track into Nevada by late Sunday then will begin to transition to a warmer pattern Tuesday. By midweek, there will be zone of upper level high pressure stretching from off shore California eastward into the central and southern Rockies. This is not shaping up to be a strong high so expect low to mid 90s Wednesday and through the remainder of next week. by Thursday, a new tropical storm will be to the southwest of Cabo San Lucas, however, the configuration is such that tropical moisture will be prevented from entering central California.
Forecast Mostly clear skies through Tuesday. Mostly clear Tuesday night through Saturday.

Two Week Outlook: September 9 through September 15: This model indicates high pressure will be parked over the desert southwest with a weak trough of low pressure along the Pacific coast. This configuration will result in near average temperatures for the valley with dry conditions continuing.
August: This model indicates temperatures over the next 30 days will be near to slightly above seasonal averages. Dry weather will continue, although we will have to keep a watchful eye to the south for possible tropical activity.
August, September, October: This model shows above average temperatures for much of the west, particularly the Desert Southwest. It also points to below average precipitation over the Desert Southwest, possibly meaning a less active monsoon season. The chance of precipitation for central California appears to be near average.
Wind Discussion: There will be periods through tonight with winds out of the west to northwest at 8 to 15 mph with gusts to near 20 mph possible, mainly along western Fresno County and northwest Kings County. Winds Sunday through Tuesday will be mainly out of the northwest afternoons and evenings at 5 to 12 mph with periods of near calm conditions.
Rain Discussion: Expect dry conditions.
Mid afternoon dew points: Low to mid 60. Kern: Low to mid 60.
