AccuWeather forecast: Increasing heat and humidity, chance of thunderstorms

Marine layer and its clouds nearly absent this morning. Don't be surprised by cooler conditions for most of us, especially across North Bay communities and Peninsula Coast, lower 40s. Expect 50s and 60s elsewhere.

Temperatures warm nearly 20 to 45 degrees from morning to afternoon today. Highs range from near 70 at the Coast to near 100 Inland.

You'll notice increasing middle clouds as remnants of Hurricane Elida arrive. The increase in humidity is unusual for us and will make it feel even hotter today and tomorrow. The heat and humidity also create a chance of thunderstorms today and tomorrow.

The clouds and humidity hold lows well above average tonight. Some of us never get comfortable, 70s and 80s in our hills and mountains with 60s elsewhere.

Friday and Beyond:
EXCESSIVE HEAT WATCH: 12PM Friday - 9PM Sunday
Dangerous heat creates record warmth tomorrow. Humidity and chance of thunderstorms continue

Our extended heatwave features a roller coaster of above-average temperatures through Wednesday of next week. Humidity levels return closer to normal starting Saturday.
