August 11, 2022/report

August 11, 2022

Most locations yesterday were huddled in the mid 90s, just slightly below average for mid August. Today will be the beginning of a slow warming trend which will eventually lead us into a prolonged period of hot weather next week. the big players are a low just to the west of Portland, Oregon and an upper high situated over the southern Rockies. The high clouds above the valley floor this morning are not from the monsoon, but are simply embedded within a southwesterly flow aloft. However, the very active monsoon season will return this weekend and especially next week. the high over the southern Rockies will retrograde and expand westward over California. The clockwise flow around the high will cause monsoonal moisture to rotate in from the southeast this weekend. High resolution models indicate the high will be further west than we’ve seen in a while, possibly allowing some deeper, richer tropical moisture to move in over the mountains and deserts of southern California and the Sierra Nevada. Thunderstorms will begin to roam these areas. A couple of models actually give a chance of measurable rain even on the valley floor Tuesday and Wednesday of next week as moisture from northwest Mexico moves northwestward. The chance of anything measurable at any given location is very small. Typically, these bouts of monsoonal juice result in sprinkles and occasionally a few hundredths, but little else. Still, all of this is worth careful scrutiny. Along with the southeast flow will come a return of hot temperatures as triple digits will become a way of life. Temperatures Tuesday through Friday of  next week should be in the 101 to 106 degree range. It’s possible, though, that cloud cover could blunt the heat, but that’s not guaranteed. Both the 6 to 10 day forecast and the two week model are still indicating a very active monsoon with occasional visitations from subtropical moisture from old Mexico moving into California from the southeast. The monsoon has been drier than average the past several years. Fortunately, this year it’s bucking that trend.

 

Forecast: Other than occasional high clouds, it will be mostly clear through Saturday. Mostly clear to occasionally partly cloudy Saturday night through Sunday night. Variable cloudiness Monday through Thursday with a slight risk of some sprinkles or isolated showers or thunderstorms, mainly near the foothills.

Two Week Outlook:  August 18 through August 24  This model shows a continuation of an active monsoon season over the Desert Southwest and occasionally California with daily chances of thunderstorms over the mountains and partly cloudy skies over the valley. Above average temperatures will continue.

 

August:  This model is quite generic, indicating the same trend of high pressure resulting in generally above average temperatures for the month of August. Precipitation will be near average, which means very little to none. This model continues to show an active monsoon over the west which may visit California from time to time.

 

August, September, October: Upper level high pressure will be more dominant over the next few months, resulting in somewhat above average temperatures. This year’s monsoon, which has been an active one so far, will result in a continuation of above average precipitation over the Desert Southwest and possibly the Sierra Nevada.

 

Wind Discussion:  Winds will be mainly out of the northwest afternoons and evenings at 5 to 12 mph through Sunday. Winds during the night and morning hours will be light to near calm.

 

Rain: Yet another round of monsoonal moisture will be arriving this weekend. High resolution models for Monday night through Thursday are hinting at some deeper tropical  moisture moving through with a chance of sprinkles or even a light shower or thunderstorm, especially near the foothills of the Kern County mountains and the southern Sierra Nevada. The chance of measurable rain at any given location is very low, however isolated pockets could pick up a few hundredths. We’ll know more as we head deeper into the weekend and can tweak this forecast.

 

Frost:  All locations will be above freezing tonight and each night for the foreseeable future.
