Well, fall finally arrived in a big way with an upper level trough digging into The West. After starting the week around 100 degrees for many we are talking about weekend high temps below average. Clouds at the coast have also pushed into the valleys, and even though there has been some clearing we’ll see this reform again tonight.
Along with those clouds pockets of mist and drizzle are possible as well, perhaps even measurable amounts for some. There will be a change in the cloud situation later Saturday, winds pick up and should mix out the clouds but those NW winds up to 25mph will also be a cool wind. Saturday’s temps look to be the coolest in the forecast with beaches in the 60s and coastal valleys in the 60s and low 70s, inland valleys will also be in the lower 70s. Not much change Sunday, still cool.
The trough causing the cool-down lingers into Tuesday for continued cool temps though some warming begins Tuesday. Wednesday-Friday next week we’ll see a ridge in the upper atmosphere which will cause a warm-up. That said, it will only push temps in the the upper 70s at the coastal valleys and lower 80s inland. Not triple digits in this outook.
