Summer Takes a Break; Big Cool-Down This Week

Onshore flow and the return of the marine layer means below-normal temperatures later this week.

Relief.  Real tangible relief.  Don't get me wrong, it's been cooler out there.  Later this week, however, it'll actually feel cooler.  Forecast highs this week are well below normal, and we'll sustain those cool temperatures into the weekend.

So what's the deal?  Remember that low pressure system I talked about last time?  As it slides east over the next several days, it'll flatten out the ridge of high pressure and force it south, taking the heat with it.  So instead of southeasterly flow driving hot air up from Mexico, a nice pleasant southwesterly flow will stream in cooler air from the Pacific.  At the same time, the onshore flow will push monsoonal moisture to the east, effectively ending the thunderstorm threat in the deserts.

Here in Studio City, this likely means an increase in high clouds, maybe some fog in the morning, but the big story are the temperatures.  The cool-down has already begun.  Highs today were in the low 90s, and the National Weather Service forecast says tomorrow we won't even make it to 90.  By the time Thursday rolls around, we're looking at highs near 83!  That's an average temperature in October!

Looks like we'll ride these cooler temperatures through the weekend, however on Monday models are pointing towards another warm-up.
