Temperatures soared across the Southland early this week, with many long-standing record high temperatures matched and some broken.
The official observation station at Bob Hope Airport reached 93 on Monday, tying a mark of 93 set back in 1976. At the Studio City Weather Center, the high was 95.
Winds shifted onshore on Tuesday, signaling the approach of a low pressure system.
As the low drops out of the north, it is expected to take more of an inland track, which will isolate it from the moisture of the Pacific Ocean. These "inside slider" type low pressure systems aren't known as rain-makers, but can produce breezy conditions. Accordingly, winds could be brisk towards the end of the week.
The onshore winds will also funnel cool air into the area, and we're already starting to feel the effects.
Wednesday was expected to hit an early high in the mid 70s and see temperatures decline through the afternoon hours. By Friday, the daytime high will struggle to reach the mid 60s. Overnight temperatures will be downright chilly, with lows reaching the low to mid 40s.
While the nature of the low will limit the amount of rain we see, there is still a small chance for light rain and drizzle as the system moves through the region. Amounts will be light, and chances are we won't see much in the way of measurable rain.
In the mountains, the colder weather means that the snow level may drop as low as 3000 feet, bringing a threat of the white stuff to the Grapevine section of the I-5 Freeway.
The warm/cool pattern will continue this weekend. As the low exits the region to the east, high pressure will once again build in from the west. With offshore flow expected to develop on Sunday, things could really warm up again early next week.
