July, experts are saying, may bring the hottest day of the year to parts of the Bay Area. With the balmy conditions also comes the possibility of a thunderstorm. Hyperlocally, there may be a back sweat situation. It was a warm weekend, so we're mentally prepared.

According to CBS SF, who are doing the 4th of July Weekend forecast early and often this week, coastal fog today will clear and conditions will turn quite muggy with those possible T-storms overnight.

We reach peak temperatures Wednesday, where inland temps will be getting into the upper 90s. For better or worse, Weather Underground says we'll max out at around 75 in the sunnier areas of San Francisco

“What will make this week unique is we began June unseasonably mild, and we will end unseasonably warm,” KPIX 5's Roberta Gonzales tells us “We will have two days in the 100s and then remaining warm inland in the 90s.” Gonzales says that "In particular, I have my eye on Fairfield" for the highest of the highs.

Expect mid-60s temperatures for the big weekend in SF, but if you're traveling to Yosemite, Tahoe or other parts warmer, keep an eye on these rising temps.
