Air temperatures this afternoon are expected in the upper 80s to near 90 degrees, with a 70 to 90 percent chance for temperatures greater than 85, especially in the southern San Joaquin Valley. While it may be tempting to cool down in the area lakes and rivers, keep in mind that water temperatures can be much colder than air temperatures due to the water originating from snowmelt runoff. It takes less than 15 minutes to lose your dexterity in water below 60 degrees! Always wear a life vest, always bring a life preserver with you, and do not go into closed rivers, streams, and lakes.

An approaching system will result in precipitation this weekend, mainly concentrated in the Sierra Nevada and surrounding foothill communities. There is a 60 to 70 percent chance for a trace of snowfall at the snow level, which is expected around 8,000 feet. Though, with warmer ground temperatures, snow will struggle to accumulate except at the peaks of the Sierra.

An area of high pressure building in over central California and the western United States next week has a likely chance (70 to 90 percent) to cause the first 90-degree highs for much of the San Joaquin Valley. These temperatures are around ten degrees above normal for this time of year, so make sure to take precautions to limit the risk for heat-related illnesses.
