A ridge of high pressure building over Northern California is forecast to deliver a quick warming trend, according to the National Weather Service.
Look for temperatures in the 90s, perhaps starting Tuesday in Sacramento. The warmest days are expected to be Wednesday and Thursday.
The ridge of high pressure centered over the north state will bring the highest temperatures so far this year, drying out gardens and melting the meager Sierra snowpack. Snowmelt will chill rivers and lakes just as sun worshippers head to beaches to enjoy the spring warmth.
The weather service warns of springtime dangers inherent in cold waters. Hypothermia, which can be fatal, occurs when the body’s core temperature falls below normal.
NWS projections for degrees over normal for Thursday afternoon:
Sacramento: 18 degrees
Fort Bragg: 11
San Francisco: 14
Grass Valley: 18
South Lake Tahoe: 13
