Cool, Cloudy Weather Expected This Week
The San Fernando Valley will be cooler than normal and frequently overcast this week due to the southern movement of the jet stream.
“We’re going to have a deepening of the marine layer for the next few days,” said John Henderson, a meteorologist with the National Weather Service in Oxnard.
The marine layer is a mass of moisture-laden coastal air that accounts for much of the low clouds and fog typical in the mornings this time of year. Often, the cloud cover burns off by afternoon, but this week some cloudiness will persist throughout the days, Henderson said.
“Later in the week there may be a little bit better clearing in the afternoons,” he said.
The unusual weather is caused by a high-pressure system north of Hawaii, said John Sherwin of WeatherData, a which provides weather information to The Times. That system has forced the jet stream south into Northern California.
The stream is sending low-pressure air into Southern California. But it is not enough to bring any precipitation to the region.
On Friday, the San Fernando Valley should see more winds as the Hawaiian high-pressure system pushes into the region, Sherwin said.
High temperatures today will be about 70 in Burbank and 73 in Woodland Hills.
