The Bay Area could get even colder this week

Wet weather in the Bay Area and snow in the Sierra will last through Tuesday morning. After that, the thermometer will dip: cold air will keep temperatures cooler than normal this week, with highs in the 50s across most of the Bay Area. Nighttime temperatures will turn even colder, with lows dropping to the 30s and below 40s for most spots. The North Bay valleys and East Bay inland could approach freezing. The weather will be dry with clear skies for the next two days as the low pressure that brought the rain recedes and the high pressure sets in. By the end of the week, the wet weather will return.

The high will settle along the California/Oregon/Nevada state lines beginning Tuesday. This will give Northern California clear skies, dry conditions and light winds.

The Bay Area has been colder than normal due to recent storms – and after the clouds part on Tuesday afternoon and evening, temperatures will drop even further overnight. This is because the clouds act as a blanket, keeping temperatures stable. Clear skies will help release any relatively warm surface air into the atmosphere, making room for cooler dense air to sink. Winds will also be lighter over the next few days. These cold mornings will last all week, with the coldest morning on Wednesday.

Freezing mornings are expected in Northern California this week.  That's what the Bay Area can expect Wednesday morning.
