The delta breeze is back Friday, bringing an abrupt end to the triple-digit heat wave that’s been gripping northern California.
Downtown Sacramento tied a record high of 110 degrees on the 4th of July, tying the old record set back in 1991. The seven straight days of temperatures 105 degrees or hotter also tied the record for the longest streak of temperatures that hot, set back in August 1990.
Cooling west winds from the coast will blow through the delta and into parts of the valley on Friday, dropping high temperatures by 15-20 degrees! Sacramento and Stockton will top out in the low 90s, with other parts of the valley – farther away from the breeze – hitting they the mid 90s.
The cooldown continues Saturday with highs falling back into the upper 80s in spots!
The dominant ridge of high pressure that had been baking the region has now retreated back into Arizona, and a weak trough of low pressure will continue to keep northern California in the low 90s as we round out the holiday weekend on Sunday.
