The Central Coast is in the cold air in the wake of a cold front that passed thru the area on Sunday. Now that the windy conditions have subsided the clear skies and dry air will produce very cold temps both inland and at the immediate coast.
Hard freeze warnings are active for inland valleys and freeze warnings are in place at the coast. The difference between the two are the severity. The hard freeze warning is for temps which will locally drop into the teens and lower 20s, the freeze warning is for temps which will cool lower than 32 and spend several hours there and in certain locations even dip into the mid to upper 20s.
The areas under a warning tonight into tomorrow morning are also in a watch for tomorrow night into Wednesday morning.
Offshore winds in the night and morning hours will keep the air dry and skies clear which also promote this kind of cooling.
High pressure is rebuilding which will mean some slow warming across the week.
Several low-pressure systems should bring more clouds later on Saturday. A trough digs in for much of next week and we could see rain Monday-Wednesday.
