A hint of heat is heading to the Bay Area, but that’s all it will be

In specific areas of the Bay Area the weather temperature will begin to dial up a insufficient ticks on Tuesday and then several more again on Wednesday according to the National Weather Operation Yet even for those areas the upward movement won t signal anything larger or hotter in scale As of right now it s not looking like we have any massive heat wave anywhere building anytime soon NWS meteorologist Matt Mehle mentioned on Tuesday It s going to be cool to mild really all the way at least into early July Related Articles Wildfires Which parts of California are at highest fire hazard this summer New map shows Bay Area locations with highest menace of ember-driven wildfires What s behind the smoke advisory in the Bay Area Short-lived Bay Area heat blast didn t make conditions any less dangerous Along with brief heat wave comes Bay Area s first Spare the Air alert So it goes with a continuous weather pattern that has settled in on the region over the past couple of weeks and that Mehle explained shows little sign of changing The effect so far in the spring of has been the absence of any long extended heat wave The big driver of that is that there is an proceeding jet stream that s is farther south than we usually see at this time Mehle declared So rather than being at a place in the atmosphere that allows the high-pressure ridge to build this jet stream is bringing with it an area for the low pressure to have an effect Within that pattern have been a handful of fluctuations similar to the one that will push up temperatures in the hottest parts of the region through Wednesday For far eastern Contra Costa County cities such as Discovery Bay Brentwood and Antioch that means temperatures in the low s on Tuesday and the high s Wednesday Brentwood is forecast to peak at degrees and Antioch is expected to reach on Wednesday The temperatures elsewhere also will run warm though not quite to that extent Livermore and Pleasanton generally the hottest spots in Alameda County are expected to peak Wednesday at and degrees respectively up about degrees from their forecast high on Tuesday For cities in the Santa Clara Valley temperatures are expected to peak at about degrees on Wednesday and about or on Tuesday Closer to the coast it will remain cool The hotter inland places will go that direction on Thursday Mehle commented Temperatures are expected to fall as much as degrees in the hottest places It s going to be a pattern change he commented A trough of low pressure will be swinging through from the north bringing cooler air with it There will be even more cooling by Friday The cooler to mild weather is expected to stay in place for at least a week and possibly two according to the weather system s long-range forecast It remains unclear at this point whether extreme heat will find its way to the region by the Fourth of July holiday though Mehle commented there s nothing to indicate a key change We re seeing average to normal temperatures all the way out for a couple of weeks he declared
