SAN FRANCISCO (KRON) — People across the Bay Area are waking up to strange summer weather Friday morning.

StormTracker4 shows rain and lightning and humid, damp conditions are widespread.

The change seems abrupt after several weeks of hot, dry days that reached into triple digits in many Bay Area cities.
