RIVERSIDE, CALIFORNIA

***Much less thunderstorm activity expected today***

Yesterday, a significant upper level disturbance triggered over 3,500 lightning strikes across the geographic area. A few areas in the Sierras received a quarter of an inch of rain, but most regions saw only a few hundredths of an inch of rain from the storms. Today, drier air will begin to filter into the area, which will result in fewer thunderstorms today and throughout the rest of the week. Scattered wet storms will still be possible in the Sierras with isolated storm coverage near the mountains of Southern California. Storm movement will generally be to the northeast which will keep storms from moving into the valleys and foothills. Temperatures will continue to run about 5 degrees above normal with highs in the 90s in the valleys to 110 in the low desert, but there will be a noticeable drop in RH in Southern California today which will make afternoon temperatures feel more comfortable. Wednesday, a thick deck of mid and high level clouds streaming into Southern California may keep temperatures a couple of degrees cooler through the middle of the week. This weekend, a fresh surge of monsoonal moisture may return to the southern part of the state. This will likely result in numerous storms developing in the deserts and adjacent areas of the Cleveland and San Bernardino National Forests by Saturday. Winds will be light through the period. END/RK
