SYNOPSIS. Monsoonal moisture will continue a slight chance of thunderstorms this afternoon for the mountains and high desert areas. An influx of monsoonal moisture from the south will bring more clouds and greater chances for showers and thunderstorms mainly for the mountains and deserts Friday through Saturday. Then drier with a gradual warming trend for Sunday through the middle of next week.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

Building cumulus clouds over the mountains have been vertically challenged mostly, trying to bubble up into thunderstorms. Only one storm in the southeast corner of San Diego County has succeeded so far. We expect only a few legit thunderstorms this afternoon in the mountains and high desert. Temperatures inland are way up: 113 in Thermal and pushing 100 in the Inland Empire and high desert at 1 pm. Any tstorms will diminish by 5 or 6 pm. Bigger changes come Friday and Saturday as a thicker layer of moisture arrives from the southeast. This will bring a better chance of showers and thunderstorms, some of which could drift a little west of the mountains and some showers could happen outside of the afternoon windows, like Friday evening through Saturday morning. The instability actually decreases with what looks like significant cloud cover at higher levels. So there will be a mix of showers and thunderstorms for mountains, deserts and far inland valleys. Recent guidance has backed off the coverage and amounts of expected preciptiation, however, so this will have to be monitored for our forecast precip amounts. The added clouds and humidity will literally dampen max temperatures. An upper low off the northwest coast will push aside the moisture Saturday night and Sunday, effectively shutting off the monsoon faucet. On Monday and Tuesday high pressure aloft strengthens right over our region. This and the drier air will boost inland temperatures, back up to around what they were today (100 or so in the Inland Empire and high desert, and 112 or so in the lower desert) by Tuesday. Some ensemble guidance shows moisture increasing from the east around next Wednesday or Thursday, but shows it mostly skirting to the south through Mexico. The forecast is dry next week, with areas of night and morning coastal clouds, and temperatures a few degrees above seasonal average.

AVIATION. 292040Z . Coast/Valleys . Patchy low clouds with bases 500-1000 feet lingering at the coast this afternoon. Areas of low clouds with bases 600-1200 ft MSL increasing in coverage after 04Z Friday, spreading up to 15 mi inland by early Fri morning. Vis restrictions of 2-4 miles in BR/HZ possible where stratus nears higher coastal terrain.

Mountains/Deserts . SCT-BKN clouds at/above 20,000 ft MSL and unrestricted vis through this morning. Isolated SHRA/TSRA over the mountains and in the High Desert this afternoon . ending around 02Z Friday. CB bases near 10,000 feet MSL and tops to 25,000 feet MSL. Gusty outflow winds and reduced vis in RA possible in/near storms.

MARINE. No hazardous marine weather is expected through Monday.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
