Break Before More Rain Arrives

Tuesday will be mainly dry before our next round of light rain arrives. The next chance for early season rain is on the horizon, but we’ll be mostly dry on Tuesday—you can never rule out a little drizzle in the low clouds! Overall troughing continues on the west coast and the next disturbance will rotate in on Wednesday. Latest trends have been slower and having the low stick around until Thursday. Rain chances Wednesday through Thursday. On Thursday, we’ll have some instability driven convection over the hills and potentially some rain wrapping around the low back into our area. Rain totals will remain low, though could be higher if a thunderstorm develops over the mountains.

AIR QUALITY: Good to Moderate

Today: Coastal clouds leave the valleys and scatter on the coast but the addition of high clouds will keep coastal coverage “mostly” and inland areas “partly.” Slightly warmer with coastal high sin the low to upper 60s and upper 60s to low 80s inland. Breezy onshore winds becoming windy up valleys late in the day.

Overnight: Low clouds for the coast and increasing clouds inland with patchy fog and drizzle. Lows mainly in the 50s.

Wednesday: For coastal areas, expect mostly cloudy skies with patchy drizzle and the chance for an isolated shower. Highs in the low to mid 60s. Inland areas will be partly cloudy with isolated mountain showers and a chance for a thunderstorm. Highs in the upper 60s to 70s. Breezy onshore winds becoming windy up valleys late in the day.

Extended: The shower threat lingers into Thursday, then dryer weather is expected into the weekend. High pressure builds and brings more summer time weather for the first weekend of the fall season. Temps will head upward and will be back above normal on Saturday, peaking at +10-15ºF on Sunday.
