It’s been a while but you just might need a light sweater or jacket this weekend. We have a cold front coming through and we’re going to feel a slight chill in the air. The lows are expected to get down to the 60’s and even 50’s in the northern counties. And the highs will be in the low 80’s. The first cool dry air usually doesn’t hit the bay area until mid October so it’s a bit unusual. But enjoy it while it lasts, we’ll be back to being hot again next week.
