Some of the coldest air of the season settles in tonight. Interior valley lows will again be the coolest in the middle 20s but even coastal temperatures look to freeze tonight. Typically the ocean influence keeps the coastal areas above freezing but the current pattern of night and morning offshore winds will negate some of the ocean moderating influence on temperatures.
A freeze warning is in place for the west-facing coastal areas of SLO and SB county tonight with the SB Southcoast under a frost advisory.
Not only will the overnight lows be cold but the daytime recovery of temps despite sunshine will be limited to the lower 60s. Similar daytime highs will take place into early next week. Inland highs will get into the upper 50s into early next week.
A weak low pressure system and front come thru Sunday but the air is too dry for precip. Not a lot of change thru next week except that overnight lows do moderate a little. Mid-range models are showowing rain opportunities as early as next weekend (not this weekend) in a patter that shows signs of getting more active. Stay tuned.
