First of all, my many thanks for the rainfall reports throughout the valley. Most were from trace amounts to as much as .33 at Famoso, .02 to .06 at Jasmine, and .10 at one location in Visalia. Most of my regularly monitored stations picked up trace amounts to less than .05. Yesterday we saw a reverse rain shadow. While generally light amounts of rain were received west of the Sierra Nevada, flash flooding was occurring from the summit of the Sierra Nevada out over the Owens Valley. Radar this morning is pretty clean with a few light showers in the northern part of the valley. The bulk of the shower activity at this hour is off the central coast. The best chance for measurable rain will be this afternoon as the moist air mass destabilizes once again. Winds aloft this morning are quite light so the best chance of measurable rain will be near the base of the mountains on all sides of the valley. We’ll keep a minimal chance of showers in the forecast for Monday as it will take one more day before the westerlies finally break through Monday night and will continue for this upcoming week. speaking of this upcoming week, it will be dominated by a deepening trough of low pressure with westerly winds aloft. A rather robust onshore flow will prevail, flooding the valley with cooling marine air with highs only in the mid to upper 80s beginning Wednesday and continuing through the week. any precipitation will be confined to the Pacific Northwest and far northern California this weekend. otherwise, it will feel as though a touch of fall was in the air.
Forecast: Variable cloudiness through Monday night with a chance of showers, mainly this afternoon and evening and possibly Monday afternoon and evening. A slight chance of an afternoon thunderstorm. Becoming mostly clear Tuesday through Sunday with pleasant temperatures.

Two Week Outlook: September 18 through September 24: 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 variable to around 12 mph through Monday. local gusts to 20 mph will be possible near showers. Winds Tuesday and Wednesday will be mostly out of the northwest afternoons and evenings at no more than 12 mph and will be light and variable during the night and morning hours.
Rain: There’s still a chance of scattered showers and isolated thunderstorms, mainly this afternoon and again Monday afternoon. Highest risk will be right along the mountains on all sides of the valley. Most locations will remain dry, although it’s possible .10 or more could occur in isolated locations. Dry weather will return Monday night and Tuesday with dry weather and pleasant temperatures continuing through next week and more than likely beyond.
Frost: All locations will be above freezing tonight and each night for the foreseeable future.
