Temperatures hit the high 80s for much of the Bay again Thursday and may reach the 90 degree zone in the South and East Bay. The reason is a high pressure system that is going to stick around one more day.
Wednesday was the hottest day since October 2 of last year. The hottest spot was Santa Clara and Gilroy. Those cities both hit 92 degrees. Pleasanton hit 90 and Walnut Creek hit 88, according to the National Weather Service.
The system is not expected to last long with the warm front pushing out by Friday. There is even a slight chance of a shower on Mother's Day Sunday.
Although the warm weather is nice, when temperatures heat up it also causes fire danger to rise. There is also the potential of flooding from the Sierra snow melt.
