Blog: Unsettled Weather Welcomes December

A series of storms are lined up and heading for California. Rain is a definite possibility.

Kiss the pleasant weather goodbye. California is in for a long stretch of damp, gloomy, unsettled weather.

Tuesday will be the last of the sunny days. The temperatures are already taking a turn towards the more mild as the high pressure ridge responsible for our awesome week of spring-like conditions breaks down and winds shift onshore.

A low pressure trough with cold front in tow will move quickly through on Wednesday. 

If you're headed north, the storm will pack more of a punch. Santa Barbara and San Luis Obispo counties are looking at up to an inch-and-a-quarter of rain in most areas on Wednesday, with some favored south-facing foothills seeing up to two inches. They're also facing some high winds as the front passes.

Here in the LA area, though, the system will be more subdued. We're not expecting much in the way of high wind or heavy rain at all. Timing on the front passing through looks to be during the late afternoon/evening hours here in the Valley, and that will be when we'll see the best chance for rain. Right now forecasters are calling for up to a half-inch of the wet stuff to fall in our neighborhood with this system.

The extended forecast looks only slightly better. Southerly flow will remain in place, along with the low pressure trough, justifying a chance for rain through the end of the week. However with no cold front available to mix up the atmosphere, the rain will be hit-or-miss, and any rain that does "hit" will be light. 

Temperature-wise, things will be pretty seasonal, although it'll feel much cooler without the sunshine. Highs will be in the mid to upper 60s through the end of the week, with lows in the upper 40s to low 50s.

Things don't look to improve until Monday, when the low pressure trough finally pushes out of our area, taking the unsettled weather with it.

The good news is that all this rain will literally clean the air. An odd temperature inversion in place for the past several days has caused a severe buildup of pollutants in the atmosphere here in the San Fernando Valley, and the AQMD has been issuing alerts all week. The coming rain will wash all that crud out of the atmosphere, and the front that pushes through will mix out the inversion layer, solving our smog problem.
