Inland heat returns quickly

The driver of all of this week's weather has been the position of an upper level high pressure circulation. The center of that circulation has been too far east to drive hot temps but that position is shifting back to the west.

Already today inland temps started to creep back up but by Friday we'll be pretty close to the triple digits in the interior of SLO county.

I think temps peak Saturday around 100. If there is any cooling Sunday it looks very minor. We might need a heat advisory for the weekend, stay tuned on that.

Closer to the coast I think we'll see marine influence but the marine clouds look pretty low. Where they form they could be stubborn and afternoon clearing could be partial. I expect beach highs in the 60s and 70s. Coastal valleys will be in the 70s and low 80s for the next few days. The Southcoast looks to be in the middle 80s Friday and thru the weekend.

We'll cool across the board early next week as the 4 corners high moves east again. Over the weekend we'll probably see some high clouds from the monsoon flow but I doubt we'll see mugginess or convection.
