The National Weather Service has issued a Freeze Watch for the Mother Lode and the Northern San Joaquin Valley, which is in effect from late Saturday night through Sunday morning.
Low temperatures will drop to near or a little below freezing in the Central Valley on Saturday morning. Even colder temperatures are expected on Sunday morning with temperatures dipping into the middle to upper twenties for several hours.
Therefore, a Hard Freeze is possible over Northern California on Sunday morning.
Low temperatures below twenty-eight degrees for several hours can kill crops.
A Hard Freeze is defined as minimum temperatures at or below twenty-eight degrees for at least three to five hours.
Protect vegetation and sensitive plants the next couple of mornings and especially Sunday morning. It is recommended that pets are brought indoors.
A Freeze Watch means sub-freezing temperatures are possible. These conditions could kill crops and other sensitive vegetation.
