The National Weather Service is warning of a "heat advisory" this weekend. All North Bay valleys and East Bay valleys should be on alert for oppressively hot weather continuing until Sunday. "High temperatures are expected to reach the 90s and as high as 101," reports the NWS. Also, an "excessive heat warning" has been placed on Santa Clara and San Jose until Sunday. So, if you can, stay out of the sun, turn up the air-conditioning, wear a hat, and check on the elderly folks who wilt under this kind of heat San Francisco, however, will be delightful throughout the weekend. Check Weather Underground for more information.
