Scattered storms and lightning continue to move in to the Bay Area today as monsoonal moisture streams in from the Desert Southwest. Humidity has significantly increased and will bring temperatures down but make it feel more uncomfortable. Highs will reach the lower 90s for the Tri-Valley while San Francisco has more clouds and highs in the lower 70s. Storms could redevelp this afternoon as temperatures heat up and cause an unstable atmosphere.
The pattern changes in time for the holiday weekend as a stronger onshore flow brings back seasonable temperatures.
Have a great day,
Meteorologist Kari Hall
