Currently we have a ridge of high pressure dominating the area with the trough that brought strong winds to eastern Kern County still slowly moving out and weakening. This ridge has helped keep temperatures seasonable. However, model ensembles have a strong agreement that the first of two trough starts moving in on Sunday and Monday as the ridge weakens and moves east. This first trough will bring a few changes to the area. Latest probabilities show a drop from a 65 to 95 percent chance of 70 degrees or higher through Monday before dropping to near zero on Tuesday. In addition to the cooler temperatures, this trough brings a 25 to 40 percent chance of a tenth of an inch or more of rain to the San Joaquin Valley and a 25 to 45 percent probability of 3 inches or more above 5,500 feet in the Sierra Nevada. However, models have had shifted the moisture to the north gradually leading to the amount of rain and snow to decrease. Winds also will pick up in eastern Kern County due to the trough that a wind product may be issued at a later time. After this first trough moves out, a weak ridge will build in bringing a rebound in temperatures. Latest probabilities have a 20 to 50 percent chance of high temperatures of at least 70 degrees on Wednesday and Thursday. A second trough starts moving in late Thursday into Friday. This second trough brings better chances of precipitation and a 80 percent and higher chance of high temperatures of 70 degrees or below. This bodes well with the CPC`s 6-10 and 8-14 day outlooks having a 40 to 50 percent chance of above average precipitation and a 40 to 60 percent chance of below average temperatures. && .AVIATION... 12Z Update VFR conditions will prevail across the central CA interior for the next 24 hours. && .AIR QUALITY ISSUES...
