***Scattered wet thunderstorms expected over Southern California this afternoon***

The upper level low which brought abundant thunderstorms activity to portions of the area has drifted further southeast and will track through northern Baja this afternoon. This will result in another round of scattered wet thunderstorms over the southern part of the state. Unlike yesterday, the storms died off overnight, but by the late morning into the early afternoon hours, thunderstorms are expected to develop near the higher terrain and the deserts of Southern California. The storms may be most numerous today over the Cleveland and southern San Bernardino National Forest eastward into the Mojave Desert. Scattered storms may also occur on the eastern side of the Angeles National Forest and portions of the Inland Empire. Further north, one or two storms may occur along the Sierra Crest. Temperatures will continue to be a couple of degrees below seasonal averages with highs in the lower 90s in the San Joaquin Valley, upper 80s in the valleys of Southern California to the 70s in the mountains. The low will be out of the area tonight, which will lead to a quiet weather pattern over the weekend into early next week. Another trough may drop into Northern California over the weekend which may keep widespread marine layer stratus forming each night with slightly below normal temperatures going through Sunday. Next week, a ridge of high pressure is expected to expand into the region, leading to a warming trend. Temperatures may be above normal by next Wednesday. Onshore flow may produce winds of 15-30 mph in and near the deserts Friday and Saturday afternoon. Minimum RH will likely drop into the teens by Saturday over most areas above 2,000 feet, away from the coast. Again, no further thunderstorm activity is expected after today through the period. END/RK
