Forecast

July 30, 2022/report

July 30, 2022

Upper level high pressure over northern California and its clockwise rotation is moving an abundant amount of moisture from the monsoon into central California. Heavy cloud cover overnight is creating some very warm conditions on the valley floor. Bakersfield was reporting 84 degrees as of 5:00am while much of the rest of the locations were in the mid to upper 70s. daytime heating will trigger more thunderstorms along the Sierra Nevada this afternoon and again Sunday and Monday afternoons. The weak easterly flow in the mid and upper levels of the atmosphere will nudge some of these storms over the foothills. It’s possible a few of these could make it out over the valley floor with the greatest risk being Sunday afternoon when a weak ripple of low pressure moves through. Temperatures today and again Sunday may be kept down by cloud cover. However, where skies remain relatively clear, widespread triple digits will again be the norm. by Monday night and Tuesday, a low pressure system will move through the Pacific Northwest, forcing the high center to move over the Four Corners region. This will set up a southwesterly flow, nudging the monsoon and its moisture to our east. Keep in mind, though, we are still monitoring the progress of Hurricane Frank which will be roughly 900 miles to the southwest of San Diego. For now, it doesn’t look like any of the moisture from this storm will become entrained in the upper winds. This means we can expect a dry pattern Monday through Friday. The high over the Four Corners region will expand westward once again by next weekend, resulting in hot conditions with daily chances of isolated thunderstorms over the Sierra Nevada.

 

Forecast: Variable cloudiness at times through Monday night with a slight chance of isolated showers and thunderstorms this afternoon and evening. A greater risk exists Sunday afternoon through Monday. mostly clear to occasionally partly cloudy Monday night through Saturday.

Two Week Outlook:  August 5 through August 11  This model is showing a very active monsoon through the entire period with scattered afternoon and evening thunderstorms over the Sierra. There will be periods of variable amounts of mid and high level clouds over the valley floor from time to time.

 

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: During the afternoon and evening hours, winds will be mainly out of the northwest at 8 to 15 mph with locally stronger gusts. During the late evening through the morning hours, winds will be variable to 10 mph with periods of near calm conditions through Monday.

 

Rain:  A considerable amount of moisture from the monsoon continues to rotate from east to west underneath the bottom side of high pressure parked over northern California. The daytime heating process will, in part, continue to trigger scattered thunderstorms over the Sierra during the afternoon and evening hours. The weak easterly flow aloft will nudge storms towards the foothills and possibly over the valley floor. A weak upper air feature will move through Sunday afternoon and evening, increasing the chance of thunderstorms over the valley floor, especially along the east side of the valley. Storms will continue to percolate afternoons and evenings Monday through Friday; however, the flow aloft will become south/southwest, moving any activity over the Owens Valley for a dry forecast over the valley. Next weekend, the flow aloft will again be out of the southeast. For now, we’ll keep the forecast dry, but will watch carefully as we progress through next week.

 

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