SYNOPSIS. Other than isolated thunderstorms near the Sierra crest during the next few afternoons, dry weather will prevail over the central California interior for the next several days. Temperatures will average slightly above normal through the end of the week.
DISCUSSION. Very little change in the overall synoptic pattern is expected during the next 2-3 days as a weak upper level low sits nearly idle off the central California coast. Its presence will help generate isolated thunderstorms near the Sierra crest each afternoon through Tuesday. In addition to dangerous lightning, a few of these thunderstorms will be equipped with small hail, gusty and erratic winds and heavy rain. Hikers in the Sierra high country should be on heightened awareness the next few afternoons and prepare to shelter when skies turn threatening and they hear thunder.
Otherwise, clear skies can be expected over much of the central California interior during the next few days with generally light, terrain driven winds and slightly above normal temperatures.
By midweek, our focus will turn to a strong upper level ridge of high pressure centered near the Arizona-Mexico border. The models forecast this ridge to build into southern California in the 4 to 7 day period. As this high pressure ridge flexes its muscle later in the week, it will push the offshore low farther out over the Pacific. So we should see a diminishment of afternoon thunderstorms over the high Sierra by Wednesday.
There is one caveat of retrograding high pressure ridges at this time of year and that's the flow of tropical moisture to the south of them. The models hint that some mid level moisture could work its way up into California on the backside of the ridge in the Thursday through Friday time period. If so, some altocumulus might show up over our CWA later in the week along with an uptick in humidity. It remains to be seen whether this moisture will be substantial enough to trigger mountain convection. We're not banking on it right now and feel the high pressure ridge will dominate and keep the pattern dry and fairly stable through day 7. Temperatures at the 850 mb level are forecast to warm to about 27C by next weekend. This would translate to highs around 105 degrees in the hottest locations of the San Joaquin Valley and possibly as hot as 110 degrees in the desert in places like China Lake and Ridgecrest by next Sunday.
AVIATION. Isolated thunderstorms can be expected near the Sierra crest between 19z today and 03z Monday. Otherwise, VFR conditions will prevail over the central California interior during the next 24 hours.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
