We'll close the books on September with a rather cool day, October begins with some slight warming but Wednesday will see more 80s return to the Central Coast with morning offshore winds but strong afternoon onshore winds. This general pattern repeats much of the week.
It'll be cool at night in the valleys the next two nights with lows in the lower 40s. Coastal valleys will be warmer with lows in the upper 40s and lower 50s.
This upcoming weekend we'll see another trough swing thru The West with some re-development of the marine clouds (which will be wiped out by winds much of this week).
If we are looking down the road some models are suggesting the middle of the month we could see more unsettled weather.
