Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 133 PM PDT Sun Jul 16 2017 .SYNOPSIS...Skies will remain partly cloudy through this evening due to a weak disturbance moving northeastward from the coast; however, isolated thunderstorms remain a possibility along the Sierra crest. Otherwise, high pressure will continue to provide above normal temperatures, but slightly lower, for the next few days. && .DISCUSSION...Mid-level clouds continue to stream up from the coast into the San Joaquin Valley and the Sierra Nevada due to a weak disturbance. The mid-level moisture appears relatively shallow and likely will not result in additional shower activity in the San Joaquin Valley. However, enough instability remains over the higher elevations of the Sierra Nevada, so isolated thunderstorms could develop mainly from Yosemite to Sequoia NP until this evening. Today's and Monday's high temperatures will remain several degrees above average in much of the region, as the high pressure ridge remains in place. This ridge will weaken a little by Tuesday and move further eastward, and southwest flow aloft will likely remain, at least over northern portions of our forecast area until at least late in the week. Temperatures are expected to moderate and lower a few degrees in some areas, but will still remain at least slightly above average. There is a bit of uncertainty regarding the forecast beyond Tuesday. There is a small chance that some subtropical moisture could return to our area by the middle of the week. Some of the latest model runs did show a little increase in this moisture by this time. However, decided to keep the forecast dry for the next several days, including over the Sierra Nevada crest, as would like to wait and see if model solutions become more consistent. As for next weekend, there will likely be little change in weather or temperatures. At this time, models are generally showing little change in the weather pattern, and little to no subtropical moisture expected to reach our area. && .AVIATION... Areas of smoke from wildfires will persist across the Sierra Nevada and the west side of the San Joaquin Valley for at least the next 24 hours. Isolated thunderstorms are possible over the Sierra Nevada thru 04Z this evening. Otherwise, VFR conditions will prevail across the central CA interior during the next 24 hours. && .AIR QUALITY ISSUES... please see SFOAQAHNX && .CERTAINTY... The level of certainty for days 1 and 2 is medium. The level of certainty for days 3 through 7 is medium. Certainty levels include low...medium...and high.
