September 8, 2022
Temperatures yesterday were down a little from the previous day, but were still excessively hot, ranging from 109 at Los Banos to 114 at Lemoore. Most other locations were between 110 and 112. With a little luck, highs today should be just below the 110 mark. Strong upper level high pressure still stretches from Utah westward over California and will maintain excessively hot temperatures through Friday. Much cooler weather will arrive Saturday due to increasing cloudiness and an increasing chance of showers, especially in the south valley. Hurricane Kay is still off the Baja coastline and is roughly ¼ way up the peninsula. Kay has weakened into a category 1 storm and will lose hurricane status sometime tonight or Friday. By Saturday morning, Kay will be just a depression southwest of San Diego. Already this morning, the cloud canopy around Kay is reaching into the Imperial Valley, but the deeper, rich tropical juice is still well to the south. It still appears the Imperial Valley will pick up 2 to 4 inches of rain later Friday through Saturday. Rain will spread northward through the deserts of southern California Friday through Friday night, possibly reaching Kern County Friday night. Somewhat of a reverse rain shadow will form along the Sierra Nevada due to the counterclockwise circulation around this storm, creating an easterly flow. Quantitative precipitation estimates are now at .10 to .25 over Kern County and a tenth or two over Tulare County, especially the southeast portion with trace amounts to a tenth from Fresno County north. Saturday and possibly even Sunday appear quite active with even a small chance of thunderstorms. The chance of measurable rain will decrease Sunday night with just a slight chance Monday. temperatures will plummet from the 110+ levels of yesterday to the upper 80s and lower 90s Saturday and Sunday. Models show a broad area of low pressure over and along the west coast for much of next week, keeping temperatures near to marginally below average.
Forecast: Mostly clear with occasional high clouds today and tonight. Mostly clear with occasional high clouds Friday morning. Increasing cloudiness late Friday afternoon. Mostly cloudy Friday night with a small chance of showers in Kern County after midnight. Showers likely south of Fresno Saturday through Sunday with a slight chance of showers further north. A chance of showers Sunday night. Partly cloudy Monday with a slight chance of showers. Clearing Monday night. Becoming mostly clear and actually quite pleasant Tuesday through Thursday.

Two Week Outlook: September 15 through September 20: this model indicates a refreshing trough of low pressure will be along the west coast, allowing marine air in from time to time. The result will be somewhat below average temperatures and dry conditions.
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 Friday. Later Friday night through Sunday, expect variable winds to around 15 mph with stronger gusts through showers.
Rain: Quantitative precipitation amounts for the Imperial Valley Friday through Sunday are pretty impressive. Hurricane Kay will dump anywhere from 2 to 4 inches before the hurricane tracks northward where .50 inch amounts are likely along the Sierra Nevada. The valley will be in somewhat of a reverse rain shadow. Most rain events in the valley develop a rain shadow along the east side of the coast range. In this instance, the circulation pattern will create a rain shadow along the Sierra Nevada. Even so, some showers should spill out over the valley floor. It still appears anywhere from .10 to .25 is likely over the Kern County portion of the valley, stretching northward to southern and southeastern Tulare County. From Fresno County north, trace amounts to a tenth of an inch seems plausible. The chance of precipitation will show up after midnight Friday in Kern County then will spread northward Saturday morning, continuing through Sunday. Isolated thunderstorms cannot be ruled out, which could result in some locally heavy rain. Showers will begin to taper off Sunday night with only a slight risk Monday. after Monday, dry conditions will prevail.
Frost: All locations will be above freezing tonight and each night for the foreseeable future.
