The National Weather Service issued a frost advisory for the Sacramento Valley and foothills, effective from 3 to 9 a.m. Tuesday.
Temperatures in the Sacramento area during that period are expected to be in the upper 20s to mid-30s, said Karl Swanberg, a forecaster with the National Weather Service.
Gusty north winds Monday brought much drier weather across the valley, but as those winds die down, temperatures will drop, he said.
A frost advisory means that frost is possible and that sensitive outdoor plants could be killed if left uncovered.
Despite a cold start to the day, temperatures are expected to top out around 65 degrees Tuesday, a bit higher than the 63 degrees that is normal for this time of year, Swanberg said.
Overnight lows Tuesday are expected to be in the upper 30s to low 40s, with lows in the 40s forecast through the rest of the week.
Wednesday and Thursday are likely to be the warmest days this week, with highs of 66 degrees and 67 degrees respectively, Swanberg said.
A weak storm system Friday is expected to bring about 30 percent chance of rain, with the best chance for rain in the Sacramento area occurring Saturday.
