UPDATE. Updated for air quality section.

SYNOPSIS. On Monday and Tuesday a low pressure system will approach the coast, bringing temperatures back down toward normal by midweek. By late in the week high pressure will again rebuild over the region with a warming trend into next weekend.

DISCUSSION. Temperatures this afternoon are generally running 2-5 degrees cooler than yesterday across the central California Interior. It is still hot today, but changes are beginning as the high is beginning to weaken.

Monday will bring the beginning of a downward trend in temperatures as the ridge of high pressure shifts to the east and an area of low pressure off the California coast edges towards the Bay Area. With lowered heights over the forecast area some cooling will occur. This combined with additional onshore flow will keep highs topping out at or just above 100 degrees in many lower elevation locations. Winds will get gusty through passes and canyons with increased onshore flow. Temperatures will drop a few more degrees Tuesday and Wednesday, putting them near normal levels, as the low pressure system reaches the northern California coast and heights aloft drop to around 5820 meters. The flow aloft in this pattern will be from the southwest and it will be rather dry, thus no showers or thunderstorms are expected in the Sierra even though low pressure is in the region.

On Thursday the flow aloft over the Central Sierra to the south and southeast and there is a slight chance of an afternoon shower or thunderstorm near higher elevations of Yosemite Thursday afternoon along with continued high temperatures running at around seasonal levels.

On Friday and Saturday the offshore low begins to move back westward and a new ridge of high pressure edges southwestward from the Northern Rockies. This will bring another warming trend as we head into next weekend. Temperatures on the lower elevations will once again climb into the triple digits, but it does not look as hot as it has been over the last few days.

AVIATION. VFR conditions can be expected throughout the central CA interior for at least the next 24 hours.
