tonight and beyond. as you can see we are dry right now. once we hit tonight at 11:00 into about 2:00 a.m. we'll see clouds increase and also a few spotty showers right near the coastline. eventually by tomorrow morning you can see here at 7:30 we get the wet weather moving in. we are usually dealing with green on this map. take a look at the pink and the white. the pink is a rain-snow mix near middle town. the white is the possibility of snow. we may have snow there. i think the best chance would be in the north bay tomorrow morning with snow 500 to 1000 feet. overall totals as this wet weather moves in a trace of an inch to about .10. temperatures will be cold but not as cold as we have been dealing with. you'll see in the south bay down to 39 degrees.

peninsula also 39. trivalley a chilly 32. we'll have more early on tomorrow right here in the north bay. you need the heavier jacket in san francisco at 40. throughout tomorrow the wet weather will try to hang on right on down to the south bay it is right over towards the east bay. 56 in hayward. it is 55 in san mateo. looking at low to mid-50s and right throughout the north bay 57 in napa and 56 here. on the extended forecast we get that chance of low snow tomorrow and we'll also have a chance of scattered rain on thursday.

as we head throughout sunday, monday and tuesday more rain chances coming our way. still a lot of stuff happening here as we head throughout the next seven days. i think overall the biggest thing would be the chance of low snow tomorrow morning. the best chance of accumulating storm fall would be as we head throughout next week. >> all right. we look forward to that. thank you. >> coming up here at 3:00 we have an inside look at the largest venue at the olympics. here is a clue. it's not for the athletes. we'll explain. giants hall of fao
