August 9, 2022 Today will be see the next salvo in a prolonged heat wave. The only chance I see for readings dipping below 100 will  be next Tuesday and Wednesday when a weak low moves through the Pacific Northwest, weakening the high slightly. In the short term, strong upper level high pressure continues to…

August 18, 2022 The latest batch of moisture from the monsoon has rotated northward into  Oregon. Satellite imagery shows another batch ready to move into Arizona. High resolution models that predict rainfall amounts indicate much of Arizona and New Mexico will pick up 3 to 5 inches of rain over the next week with only…

August 17, 2022 Debris clouds from thunderstorm activity over southern California yesterday drifted northwestward over central California last night and this morning. these clouds essentially stopped the radiational cooling process, resulting in what I consider to be a hot morning. As of 5:00am, Porterville was reporting 80 degrees, Fresno 84, and Bakersfield 86. Yesterday afternoon,…

August 16, 2022 Strong upper level high pressure extends from one center over northern Utah across California to another high in the eastern Pacific. At the surface, pressures are slightly higher inland than they are off shore, creating a very weak off shore flow. The sounding at Monterey showed a marine layer depth of 1,200…

August 15, 2022 Yesterday saw the beginning of what will be at least a week’s worth of triple digit heat. Upper level high pressure over the Texas panhandle is building westward over California and has already effectively cut off the marine layer. The current sounding at Monterey is showing the marine layer is only 1,500…

August 12, 2022 Upper level high pressure is centered over Kansas and Colorado this morning while the low off the coast of the Pacific Northwest has moved northward to off the coast of British Columbia. The flow aloft is still barely southwesterly above central California but has turned southerly over southern California, allowing the monsoon…

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,…

All this has been brought on by the slow northward movement of an upper low off the central Oregon coast and the slight eastward shift of upper level high pressure over the Desert Southwest. Pressures…

This will trigger isolated thunderstorms over the mountains and deserts of southern California and the Sierra Nevada this afternoon and evening. Our weather is still being governed by two main features.…
