That could even be extended with temperatures that will be in the 80s to low 90s. Dangerously low humidity in the Single Digits with wind gusts tonight up to 40 miles per hour. The good news for that fire, as we head throughout tomorrow, wre expecting some calmer winds to eventually move in. 5 to about 15. Lets look at some of the top six hottest cities across the bay area. Every one of these as you can see reached 100 degrees today, cupertino, gilroy, palo alto, and also in all ma deny valley. But we are beginning to see sign fz changes.

I dont think well wake up tomorrow and have a completely foggy morning at the coastline, but just getting that wind to change is going to bring us much more comfortable temperatures. You can see in san jose instead of 100 degrees like we had in the south part today, well go with 94. Seven degrees cooler in palo al alto. Instead of 90s we drop to 88 in san mateo. After record setting heat two days in the 90s in downtown San Francisco, 80 tomorrow there. And the marina, likely 79. Across the north bay, east bay and trivalley, youll see 92 in napa for tomorrow, cooler breeze near oakland, should drop you to 86, also helping to drop the fire danger.
