Bay Area residents should prepare for cold mornings this week, with temperatures around 40 degrees inland and around 43 degrees in downtown San Francisco.
Tuesday morning shall be brisk, but a slight warming trend is anticipated through midweek, in response to Dial Hoang, a meteorologist with the National Weather Service Bay Area.
Daytime highs shall be within the upper 50s to mid 60s, with San Francisco at 59 degrees, San Jose at 64 and Oakland barely cooler. By Wednesday, temperatures could climb into the low 70s in some areas throughout the week.
However, atmospheric river conditions may very well be on the horizon. “We will see the first true atmospheric river impact the North Bay around midweek and spread across the Bay Area and Central Coast by the end of the week,” Hoang said.
An atmospheric river is a concentrated flow of moisture within the atmosphere that causes heavy rainfall when it reaches land. These conditions often pose risks of flooding and other weather-related hazards.
Rain boots, layers and an umbrella are advisable as residents should prepare for wet commutes. If atmospheric river conditions fully develop, localized flooding may additionally occur.
