Marine Layer Brings Brief Relief From Heat

The good news is the 100-degree mark will not be broken for at least the next few days in the San Fernando Valley, the National Weather Service said Sunday.

Last week’s days of triple-digit highs were caused by a major high-pressure system that hovered over the entire Southwest, spokesman Bill Hoffer said. High-pressure systems tend to trap heat and block out cooling influences.

But a low-pressure system has started to move into the area, Hoffer said, and that is helping the marine layer of cool, moist ocean air to move into the Valley.

“It helps punch it in a little bit stronger,” Hoffer said. “It is pretty much normal for a West Coast area for this time of year.”

That means low clouds and fog will be prevalent in the Valley at night and in the early mornings. Otherwise, skies will be sunny.

For Monday, the predicted high temperatures are 85 in Burbank, 86 in Van Nuys, 88 in Northridge and 92 in Woodland Hills. Temperatures might reach the upper 90s later in the week, Hoffer said.
