Strong high pressure over the region brings triple digit heat to many areas of interior Northern California. Ground zero for the high heat will be the northern Sacramento Valley where an Excessive Heat Warning is posted. High temperatures around 110 degrees combined with overnight lows in the mid-upper 70s means that some people can be seriously affected by the heat if precautions are not taken. Check on the elderly. Make sure pets ands livestock have shade and plenty of water. Farther south, it will be hot as well, but enough of a breeze may move through the Delta to drop overnight lows mostly into the 60s. Above normal temperatures are expected to continue for interior NorCal through at least the upcoming weekend.
