Heat is on in the SCV

The Santa Clarita Valley is expected to sizzle this week as temperatures hover around triple digits.

Today’s forecast high is predicted to be at least 101 degrees, according to officials with the National Weather Service office in Oxnard.

Daily highs for the rest of the week are expected to be just under triple digits.

Today, and for the next 24 hours into Wednesday, relatively cool breezes are expected to offset some of the heat, but those cooling winds are expected to disappear by the end of the week, leaving just the heat.

Those breezes, according to one local weather official, are what make the local heat wave different from the deadly one experienced in the Midwest.

Dennis Swanson supplies the National Weather Service with data collected from the weather station in his Canyon Country home.

“A couple of things make intense heat different for us here in the Santa Clarita Valley,” Swanson said Monday. “For one thing, we’re right next to an ocean. So even if we have a high pressure system, as soon as the wind turns around we’ll get some breezes off the ocean.

“For the Midwest, a high pressure system just gets stuck there,” he said. “A high pressure system there has nowhere to go.”

Swanson said the Midwest experiences the same dynamic of cold air flow during the winter, with “nothing standing in the way between Chicago and the North Pole.”

“That’s why we don’t have that kind of problem. We’re going to have a period of high pressure for a couple of days but eventually it gets changed; something comes down the coast from Alaska and things change.

“The weather is a lot more dynamic for us compared to the Midwest,” he said.

Thursday and Friday are expected to be cloudless and hot in the Santa Clarita Valley, with temperatures expected to reach 97 degrees and 96 degrees, respectively.

Temperatures are forecast to drop by as much as 40 degrees each night this week.

The clouds and wind are not expected throughout the weekend as temperatures return to 101 degrees both Sunday and Monday.

Unlike the deadly heat wave gripping the Midwest, periods of high temperatures tend to normally move on after a couple of days, according to one local weather official.

According to The Associated Press, the Midwest heat wave will stay anchored over the Plains this week. This system will be very strong, pushing any storms that could potentially cool the area well to the north.

The system will produce more scorching temperatures in the 90s and 100s from Texas through the Dakotas and upper Midwest. Eastern Texas through Minnesota and the Dakotas will be under heat advisories due to heat indices spiking into the 100s and 110s in some areas, according to The Associated Press.
