We’re so cool; soon, we won’t be
Heat wave will hit Tuesday and push highs into the 90s inland
Cool and cloudy conditions are expected to continue through Sunday, but by midweek, a heat wave is expected to hit the Los Angeles area.
Temperatures will start to rise Tuesday and will peak Thursday, with highs in the low to mid-80s at the beaches and the low to mid-90s in the valleys and downtown, according to David Sweet, meteorologist with the National Weather Service in Oxnard.
The heat is expected to persist through Friday.
Although temperatures are expected to be 15 to 20 degrees above normal, records are unlikely to fall because previous years have been “so incredibly warm,” Sweet said.
Still, he said, “it’s a pretty significant heat wave. It’s not very typical for the first week of April.”
People in the area are advised to drink plenty of liquids and avoid too much exposure to the afternoon heat.
A strong onshore flow that’s bringing cooler, cloudier conditions this weekend is expected to transition to an offshore flow, which will cause air to descend into the Los Angeles Basin from the mountains, warming and drying it, Sweet said.
At the same time, an area of high pressure will move in later in the week, he said.
“We go from cooler northwest to west winds this weekend and early next week to very light northeast winds later next week, and the high pressure plus the descending air into the basin will produce very warm temperatures,” he said.
Although winds will be moderate to strong this weekend, by the time the heat wave sets in, the winds will be light, he said.
“So that’s good news in a sense, because if you have very hot, very dry conditions, plus gusty winds, we’d be very concerned about fire,” he said.
Although there may be an elevated risk of fire, the light winds combined with relatively moist vegetation due to recent rains mean it’s unlikely to be much of a problem, he said.
In the meantime, cooler, cloudy conditions are expected to prevail through Sunday, followed by some clearing in the afternoon Monday and Tuesday, Sweet said.
