Overview
- A strong marine layer and delta breeze have held Northern California daytime highs below average, keeping valley temperatures mostly in the 80s and low 90s.
- Forecasters predict a gradual warming trend into Friday with valley highs reaching the low 90s and climbing into the mid-90s over the weekend.
- The Climate Prediction Center expects below-average temperatures to persist statewide through the end of July despite this weekend’s warm-up.
- A stray thunderstorm remains possible in Mono County in generally dry conditions before another cool weather system arrives early next week.
- Cooler temperatures have eased immediate fire weather risks, but ongoing fuel drying is likely to raise fire activity later this summer.
