The main driving factor for our weather the last several weeks has been the position of an upper level ridge. It has wiggled east and west. Those movements are the difference between us being hot or mild in the interior.
The 4 corners ridge axis will move east Wednesday. That will put the Central Coast over mild SW flow aloft.
Well, that ridge is going to shuffle east for a few days. This will allow the marine influence to deepen and penetrate furter inland. This will result in mild beach and coastal valley high temps and bring inland highs from above average to below average.
Skies cleared out nicely today but coastal clouds are expected to re-develop later tonight for continued mild coastal temps.
In fact, the southern Salinas River Valley temps (northern SLO county) could actually stay in the 80s on Wednesday and move in to the lower 90s on Thursday.
That ridge of high pressure builds back to the west Friday into early next week for another run of upper 90s and 100+ temps. After that models suggest some cooling with weakening of the ridge and some increasing onshore flow.
Here is a look at the highs we experienced Tuesday:
Inland temps ALMOST hit 100 today, but a big cooldown is on the way tomorrow.
