in the personal photos of betty shemis taken back in 1976, it was february 5th, 35 years ago, the last time it snowed and it stuck to the ground at s.f. it was enough for a snowman. will it be like that this time around? first, there's the issue of whether or not it is going to snow. if it is going to happen, our meteorologists are predicting the best shot will be late tonight, friday, possibly tomorrow morning, saturday. the reason tonight is because that's when attempts are expected to be at their coldest and the snow levels could then drop to 500 feet, which would certainly hit parts of san francisco. as far as how much snow there could be, there are no forecast models out there predicting anything more than an inch of accumulation at sea level. here at twin peaks in san francisco, bob redell, "today in the bay." >>> thank you so much, bob. as we take a live look outside as you can see the rain-slick roads out there causing spinouts, take it easy heading out the door. stick around, we have a lot more coming up on this weekend's storm. you can get updates any time at our website, nbc
