Nice heat relief

Night through morning coastal low clouds and fog, possibly dense, will continue tonight then spread into the valleys Wednesday through the rest of the week. Temperatures will cool gradually but remain above normal through Wednesday. A low pressure system will bring even cooler temperatures later in the week into Saturday with a slight chance of rain mainly north of Point Conception. A warming trend with possible Santa Ana winds is expected early next week.

A warm air mass remains in place along the west coast. However, remnants from a long deceased tropical system along with a weak upper level low will be moving through the area the next couple days, increasing cloud coverage at times and cooling temperatures off a few degrees. Temperatures will remain above normal through Wednesday but highs will drop a few degrees each day as onshore flow increases. 

Probably some more dense fog near the coast tonight then less so the next couple days as the marine layer deepens and cloud bases lift.

Then Thursday daytime highs finally dropping below normal for the first time in a long while as the ridge finally weakens and a split flow develops with an upper low approaching northern California. Expect we'll see widespread marine layer clouds well into the valleys with inland highs topping out in the low to mid 80s and mainly 60s to low 70s at the coast. Strong onshore trends will likely mean very slow coastal clearing but inland areas should clear out with plenty of sunshine by afternoon.

The cooling trend will continue through Saturday as that trough moves inland. There is a very slight chance of sprinkles/showers Friday/Saturday for areas north of Point Conception.

Pattern quickly shifts to a Santa Ana scenario Sunday and Monday.  This will bring us more sunshine and warm us up.
