A cold front will move in Thursday evening with thunderstorms developing ahead of it in the afternoon in our west-northwest counties, then toward the coast Thursday evening.
With high instability and moderate wind shear, there is the potential of a few severe storms with the highest risk in our northern counties.
The main threat with afternoon storms will be very large hail, but strong, damaging wind gusts will be possible as the storms form a line and push to the southeast to the coast Thursday evening.
Locally, heavy rain is expected with stronger storms. The tornado threat is very low.
Showers and storms will taper off after midnight, leaving us with a cooler, and mostly cloudy, day Friday, and a spot afternoon-shower chance.
We'll warm back into the 80s for the weekend and see another chance of t-storms late Saturday as a Pacific cold front moves in.
Sunday will be drier with plenty of sunshine behind the front and still warm.
A stronger cold front moving in by early Monday will bring temperatures and humidity down for early next week.
Tonight: Low clouds and fog with lows in the low to mid 70s and light south winds.
