Fire Weather & Rain Chances

A trough digging down the coast will keep a chance of showers in the forecast overnight. The associated upper level low will cut off over the Great Basin through the end of the week, continuing to influence our weather. Dry air will wrap around the low late Wednesday into Thursday, increasing fire weather concerns. Then, a weak low sliding in off the Pacific could enhance rain shower chances again on Friday. Beyond that, our area will remain in “no man’s land” between the stronger flow to our north, cut off lows to the south and high pressure to the west. This will likely keep the weather fair and seasonable. A Pacific storm has the potential to bring rain to the region mid-week next week.

 Partly cloudy with an isolated rain shower possible. Patchy drizzle also possible on north-facing slopes of the coastal mountains & hills. Breezy at times. Expect lows in the 40s on the coast with upper 30s to low 40s inland.

The National Weather Service has issued a Red Flag Warning from 4AM Wednesday through 7AM Thursday for the Diablo Range in Santa Clara County above 1,000ft.

Expect north to northeast winds 20 to 30 mph with gusts 35 to 45mph. Local gusts at isolated peaks and ridge tops may approach and possibly exceed 60 mph.

Wednesday afternoon relative humidity values dropping to 10 to 20 percent with localized single digits. Poor recoveries are forecast on Wednesday night with relative humidity values in the 30 to 45 percent range with localized values below 25 percent.

Wednesday: Partly cloudy and cool early with breezy northwest winds. Winds become more north-northeasterly later in the day, especially over the hills. Skies should effectively clear out by then. Expect highs mainly in the 60s with a few spots getting into the low 70s on the north side of the bay and in the northern valleys.

Thursday: Partly cloudy and occasionally breezy. Occasional low clouds near the coast and some mid to high level clouds passing through. Highs mainly in the 60s.

Extended: Expect a chance of light showers on Friday under partly cloudy skies with continued cool conditions. We’ll be dry this weekend with seasonable temperatures, then a cool-down next week.

The outlook from the Climate Prediction Center for November 25th -  December 3rd calls for the likelihood of near normal temperatures and ABOVE normal precipitation.
