The typical June pattern of night through morning low clouds will continue into next week with below normal afternoon temperatures.
Low clouds were more stubborn today across the coast and valleys with temps running even cooler. This sort of day to day variation will continue at least through early next week.
A weak upper ridge tomorrow should produce some earlier clearing and a few degrees of warming, mainly inland. Then Sunday that trend will reverse back to likely slower clearing and slightly cooler days Sunday/Monday. Otherwise not much change in the June pattern. Strong onshore flow will continue each day with locally gusty westerly winds in the interior of SLO/SB Counties.
A ridge over the eastern Pacific is expected to expand east over northern and Central California by around mid week which should lead to a warming trend and a shallower marine layer.
