Area Forecast Discussion National Weather Service San Diego CA 834 PM PDT Wed Jul 28 2021

SYNOPSIS. Lingering monsoonal moisture will continue a chance of isolated showers and thunderstorms over the mountains and deserts again on Thursday. Otherwise, it will be fair and warm with some patchy marine clouds near the coast. A bigger influx of monsoonal moisture Friday through Saturday will bring more clouds, cooler weather, and a better chance for more widespread showers and thunderstorms. Drier weather arrives Sunday, with a warming trend through the middle of next week.

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

At 7 PM PDT . there were still a few clouds lingering over the mountains and deserts, but the shwrs/tstms earlier had all faded. There were some heavy cells along the desert slopes of San Diego and Riverside Counties indicated on radar, but none hit a rain gage directly. Some patchy low clouds were redeveloping along the coast this evening. Our 00Z sounding had a weak inversion based near 1000 Ft MSL, with light and variable winds up through about 8K FT. The PW measured in the column was a mere 1.08 inch. No forecast changes are in the works this evening.

From previous discussion .

Copy and paste today's weather into Thursday regarding the chance, location and timing of both the thunderstorms and the coastal clouds. On Friday, more moisture pours into the region from the southeast. However, this moisture is higher up in the atmosphere, somewhat limiting the instability. The thicker moisture and more abundant clouds will bring a slight chance of showers early Friday, followed by a chance of afternoon thunderstorms across mountains and deserts and far inland valleys. This interesting wave of moisture continues to flow in Friday evening through Saturday morning. Nocturnal thunderstorms are very possible in Imperial Valley and showers could spill into our eastern desert regions late Friday and/or early Saturday. The surface heating Saturday afternoon will destabilize the atmosphere for the more traditional chance of thunderstorms in the mountains and deserts during the afternoon Saturday. Nearly all model guidance starts pushing out the moisture by late Saturday, leaving Sunday dry. The drier southwest flow appears stay in place, too dry for precipitation Sunday through Wednesday. Marine layer coastal clouds should make a better recovery tonight, but could get disrupted again this weekend. Look for areas of coastal clouds each night and morning. Next week the drier air and high pressure aloft will continue for a few days, allowing for a warming trend. Temperatures will peak Thursday this week, cooling down with more clouds and higher humidity Friday and Saturday, followed by a warming trend Sunday through midweek. Daytime highs Thursday and next week should be a few degrees above average, which is over 110 in the lower deserts and near 100 in the Inland Empire.

AVIATION. 290300Z . Coast/Valleys . Patchy low clouds with bases 500-1000 feet will continue to form along the San Diego County coast this evening, and spread locally 5-10 miles inland overnight. Vis reductions of 2- 4 miles in BR/HZ where stratus meets higher coastal terrain. Low confidence in ceilings at KSNA. Scatter out expected 15-17Z.

Mountains/Deserts . Mostly clear skies with unrestricted vis will prevail through tonight. Slight chances of SHRA/TSRA over the mountains and in the High Desert Thursday afternoon. CB bases near 7000 feet MSL and tops to 30,000 feet MSL. Gusty, erratic winds and lightning 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.
