the weekend both saturday and sunday. inland areas close to the low 70s. monday night and tuesday cooler changes as we go on the rollercoaster ride of the seven-day forecast. tomorrow morning certainly jacket weather as we drop maybe into some upper 30s for some of the wind sheltered north bay valleys. low 40s elsewhere. a cool start. then as we head toward lunch time temperatures in the mid 60s around san jose notice san francisco and oakland by mid afternoon. low to mid 60s. a little warmer for your friday and upper 60s in reach near san jose. saturday we've been talking about things would warm up. san jose into morgan hill, low 70s. might see some out toward solano county and a pretty similar forecast sunday. the change will be slight cooling around the inner bay and san jose plus increasing high clouds which leads to the bigger change by monday. your high temperatures in the upper 50s and low 60s. here is the rainfall estimate. this is monday night into tuesday. all of the blue indicates about 0.1 inch of rain or less.

higher totals possible up here in the north bay which is typically the case for your april to may storms which take a more northerly track. it will be cold enough monday night into tuesday. could we see a foot of snow across the sierra near interstate 80? that looks possible right now. maybe even above that by tuesday night. best totals for sierra snowfall for now look north of highway 50 but stay tuned because if you have sierra travel plans you may see a winter weather advisory being issued as early as sunday night for the weather moving in late monday to tuesday. you see the snow there around the cascades, down the sierra. showers around the bay area. it looks like later on monday right now we begin to see a chance of some rain there in the north bay. showers around the rest of the bay area once we get into tuesday. with that we will see highs from the 60s and 70s to upper 50s on tuesday. and beyond that maybe we can go 3 for 3 heading toward the following weekend right now. trending drier again. so for this weekend we have a bit of a warmup on the way.
