Watching for rain chances

Weather in 60 seconds with Erica 9 25 18

The weather pattern will remain blocked up for the next couple of days as a strong ridge over the North Pacific is undercut by an isolated low. Northerly flow will keep inland areas hot & dry, but weak flow at the surface may curtail warming at the coast. Some movement in the pattern expected as we head toward the weekend with weather systems bringing slight rain chances this coming weekend and then the week after.

... in effect until 5PM Tuesday for the Diablo Range in Santa Clara County
WIND: Northeast winds 5 to 15 mph increasing 10 to 20 mph with gusts to 35 mph tonight into early Tuesday morning.
HUMIDITY: 5 to 15% and locally lower with little or no night time recovery through midweek.
IMPACTS: Any fires that develop will likely spread rapidly.
PRECAUTIONARY/PREPAREDNESS ACTIONS - A Red Flag Warning means that critical fire weather conditions are either occurring now...or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.


Tuesday: Mostly sunny with a few low clouds near the coast and a few, thin high clouds passing over. Still a bit cool on the coast with highs in the low 60s to low 70s. Mild inland with mid 70s to mid 90s. Breezy for inland valleys in the afternoon and early evening.

Overnight: Patchy low clouds and fog along the coast and adjacent valleys overnight. Expect lows in the upper 40s to low 50s along the coast with inland spots mostly in the 40s. 

Wednesday: Patchy low clouds/fog near the coast early, then becoming sunny. Warmer, with coastal highs in the mid 60s to upper 70s, 80s to around 100ºF inland. Breezy for inland valleys in the afternoon and early evening.


Extended: After warmer temperatures Wednesday, onshore flow will be a bit stronger Thursday, cooling most areas. Clouds will then be on the increase late. A weak weather system will pass over the region Friday through Saturday. Temperatures will cool significantly inland, but remain fairly consistent on the coast. There is a very small chance of a rain shower in the northern half of our viewing area on Saturday. Highs will remain cool inland into next week. Another weather system will bring an additional (potentially better) rain chance by mid-week.

The outlook from the Climate Prediction Center for October 2nd - October 8th calls for the likelihood of near normal temperatures and ABOVE normal precipitation.
