***Cooler this week***

A trough will slowly edge into the area this week, bringing cooler, onshore flow to the district. Temperatures today will be 5-8 degrees cooler than over the weekend, especially across the inland valleys. By Wednesday and Thursday, temperatures will be a couple of degrees below normal with highs in the upper 80s to lower 90s in the valleys. Marine layer coverage will increase through the first half of the week and night through morning stratus may reach the lower slopes below 3,500 feet by Wednesday morning. Southwest winds will increase as the trough draws closer and some wind gusts to 30 mph will be possible across the Antelope Valley, Apple Valley and over Canyon Country during the afternoon hours through Thursday. Wednesday and Thursday, wind gusts to 40 mph will be likely in the Banning Pass and northern Coachella Valley. Minimum RH will be higher during the next few days, but some areas above the marine layer will see RH fall into the 10-15% during the afternoon hours. Warmer weather is expected to return by Friday into next weekend. Some moisture may creep into the far eastern deserts by Saturday, allowing isolated storms to develop near the Arizona border. No strong offshore winds or significant thunderstorm activity is expected the next 7 days. END/RK
