The steering currents at the upper levels of the atmosphere are very weak. If anything, there’s a slight north to south component. Variable cloudiness left over from yesterday’s thunderstorms over the Sierra Nevada cover most of the eastern side of San Joaquin Valley. Once the daytime heating process fires up, scattered thunderstorms will again erupt over the Sierra Nevada and possibly over the Kern County mountains and deserts.
The overall pattern as we end June and move into July is still a bit odd. The main high center of over southwest Canada with a weak zone of low pressure over the Great Basin extending westward to the Sierra Nevada. The freezing level this morning is fairly typical for mid summer and stands at 16,400 feet. Surface pressure differences are almost flat. The altimeter at San Francisco stands at 29.83 inches of mercury. The current reading at Las Vegas is 29.88 which means there is no hope for moving marine air down the valley.
As we head into the weekend, the main high center will drop southward over California with another center over the Four Corners region. This will turn the winds aloft out of the southeast which is favorable for at least a limited amount of monsoon moisture moving into central California via Mexico and the Desert Southwest.
Of interest to probably only me, tropical storm Enrique is centered near the southern tip of Baja this morning and will move northwestward across the peninsula, tearing the storm apart. None of this moisture is expected to reach this far north at this time.
Forecast: Mostly clear to partly cloudy through Thursday morning and continued hot. Mostly clear Thursday afternoon through Wednesday with occasional high clouds and continued hot.
