Summary currently, a trough of low pressure is moving rapidly through the Great Basin while a ridge of upper level high pressure builds into the Gulf of Alaska. In the meantime, a large low pressure center over Hudson Bay will develop a trough southwestward into California by Friday night. Over the weekend, a surface high will take shape over the Great Basin. A combination of all these factors will generate an off shore flow this weekend, injecting a drier air mass down the valley. Since dry air heats and cools more rapidly than moist air, temperatures by Monday will drop down into the 30s at many locations on the valley floor. it’s possible, that by early Monday morning, coldest locations could dip down to the 32 degree mark for the first time this season. It will just depend on where dew points ultimately wind up. However, no widespread frost is anticipated. In the short term, temperatures today will drop a good 8 to 10 degrees with models coming in at the 70 degree mark both today and Friday. Readings will drop into the upper 60s Saturday as a cooler, drier air mass settles in. by Monday, upper level high pressure off shore will begin to build inland, resulting in a warming trend. Medium range models are still hinting at some wet weather beginning on the third as upper level high pressure drops southwestward, allowing the possibility of a series of storms to oroe in from the eastern Pacific.
Forecast Mostly clear to occasionally partly cloudy through Sunday. Mostly clear Sunday night through Thursday.

Two Week Outlook: November 1 through November 7 This model shows periodic chances of rain for the northern 1/3 of California with a small chance of showers over central California, generally north of Fresno. temperatures will run somewhat above average.
October: This model indicates that October will be marginally warmer than average. It also points to above average precipitation from Texas t o southern California. Central California will have a better than even chance of above average precipitation.
October, November, December This model shows a marginal chance of above average temperatures over the next 90 days. There is no indication of above or below average precipitation through December. We will be dealing with a strong El Nino this winter. Whether or not that translates into abundant rainfall for central California remains to be seen.
Wind Discussion Winds through this evening will be out of the northwest at 8 to 15 mph with local gusts to 20. Winds tonight through Friday night will be generally less than 10 mph with periods of near calm conditions. Winds Saturday will again be out of the northwest at 8 to 15 mph with locally stronger gusts. Winds Sunday will be at or less than 10 mph with periods of near calm conditions.
Rain Discussion. Expect dry weather for at least the next week. models the past few days have been hinting at a possible change near November 3. On paper, high pressure over the eastern Pacific will move further out to sea. Ths will allow a moist north to northwest flow into California. Theoretically, this could allow a series of storms to move into California. We’ll continue to monitor.
