Another generally quiet period for the Central Coast before a significant fall heat-spike this weekend into early next week.

The short term forecast has some higher winds in the afternoons over the next few days. The recent lighter winds allowed marine layer to linger but the upcoming forecast should have a lot more sunshine.

We have a few frontal boundaries passing to our north and even providing showers to northern California. Here they just hep build the afternoon winds to 15-25mph. These fronts also precede the building high pressure ridge which will create the heat-spike I've been talking about for Sunday-Tuesday.

To me it looks like the ridge starts to break later next week for breezy NW winds and cooler temperatures, I think some forecasts are assuming this happens mid-week but it could be later than that.

That said I think the heat-spike will be significant with 100+ temps inland Sunday-Tuesday (maybe Wednesday as well depending on the breaking of the ridge). Coastal valley temps look to hit at least the 90s, I don't think 100 is out of the realm of possibility since offshore morning winds will be part of this event which is what it takes to get the coastal valleys to hit 100. I think some beaches will be in the high 70s and low 80s.
