After a heat record was set on Thursday, the long-absent Delta breeze began to whisper overnight, a windy weather phenomenon that is expected to lower temperatures through next week.
The National Weather Service reported that the mercury hit 108 degrees on Thursday. That broke the previous record of 107 degrees, set in 1981.
Overnight, the Delta breeze began to bring some relief from the unrelenting heat that has produced seven straight days of triple-digit heat. Temperatures Friday morning were running seven degrees cooler at Travis Air Force Base near Fairfield – and about 3 degrees cooler in Sacramento.
The high Friday is expected to be 101 degrees in Sacramento. More significant cooling is forecast for Sunday and early next week.
