Summary Today and Friday will be hot, however, the weekend into early next week will be perfect as temperatures will plummet from near 100 today and Thursday into the upper 80s Friday and low to mid 80s Saturday and Sunday. A relatively small upper high is centered over Arizona this morning. Weaker high pressure covers Arizona and off shore waters. The freezing level remains very high at 18,200 feet with a shallow marine layer at just 1,800 feet. This will rapidly change Thursday night and Friday as the marine layer deepens and surges over the coast range and through the Delta with gusty west to northwesterly winds. The catalyst of all this is a low pressure system currently off the coast of the Pacific Northwest. This low will develop a trough southward into California by Friday. Light showers will spread over the mountainous terrain of northern California. Temperatures will begin to warm again Tuesday as a zone of high pressure sets up from the eastern Pacific eastward into the central and southern Rockies. Longer range models show a tropical storm along the southern tip of Baja about a week from Friday. According to this model, steering currents will be weak. For now, it does not appear to be anything to worry about.
Forecast Mostly clear skies through Sunday. Mostly clear Sunday night through Wednesday.

Two Week Outlook: September 6 through September 13: 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: Winds during the night and morning hours will be generally at or less than 15 mph through Wednesday. During the afternoon and evening, winds will be out of the northwest. Later Thursday afternoon through Saturday, winds will be out of the northwest at 10 to 20 mph with locally stronger gusts.
Rain Discussion: Expect dry conditions.
Mid afternoon dew points: Low to mid 50s. Kern: Low to mid 50s.
