Heat Wave Continues
WEATHER STORY
A strong ridge of high pressure will begin to move in from the southeast on Tuesday. It will bring an impressive dome of hot air to the state. Coastal temperatures will peak on Wednesday as this heat noses in, but eventually, our low level onshore flow will win out, keeping the air conditioning on for the coast and nearby valleys. If you live higher in elevation or away from the coast, prepare for about 4-5 days of serious heat!
FORECAST & ALERTS
Tuesday: Mostly sunny and warmer with coastal highs ranging from the mid 60s to low 80s!—warmest on the north side of the bay—and widespread 80s-90s inland. Winds could be gusty in the afternoon and early evening.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles
under any circumstances.
Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent
rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.
Extended: Temperatures remain hot inland Thursday-Friday with a steady cool down into the weekend. Expect the return of the low clouds on the coast as early as late Wednesday and they will likely remain into the weekend with seasonable to slightly cool temperatures. Also, some high level moisture will stream in Wednesday-Friday which at the very least will lead to some high clouds. There will be some elevated instability which will have to be watched, but rain/thunderstorm chances appear low.
