A trough of low pressure passed over the Pac NW and flattened the ridge of high pressure which powered some recent offshore flow. Now that that feature is moving off to the east, we will again get some offshore flow and temps will start to rise again. The changes Friday will get coastal valleys into the upper 70s and lower 80s but Saturday and Sunday some upper 80s and lower 90s are in the forecast, even beaches will be in the mid-70s this weekend.
Northeast winds also expected to pick up in and around the Santa Lucias along the Central Coast Friday night into early Saturday with gusts to between 25 and 35 mph.
Offshore flow Sunday is a little weaker but air mass is warmer and temps should be at least as warm as Saturday with slightly less wind.
Light offshore winds look likely well into next week. This will keep temps warm, skies mostly clear and conditions dry.
Offshore flow expected to briefly weaken and turn onshore Wednesday as the next trough approaches but then quickly turns offshore again later Thu into Friday.
Models are indicating potential of a cooler and potentially wetter pattern developing after mid-month, but that is some time off and just needs more examination at this point.
