NWS San Diego, CA wrote its last area forecast discussion before the first event at Jul 9, 8:08 PM PST, 3 hours 52 minutes earlier.
Area Forecast Discussion National Weather Service San Diego CA 908 PM PDT Sat Jul 9 2022 .SYNOPSIS... Warm to hot summer weather will prevail inland into early next week, while cooling sea breezes maintain a coastal marine layer with areas of night and morning low clouds and patchy fog. Monsoonal moisture will increase next week, leading to possible showers and thunderstorms after Tuesday, mainly in the mountains. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... The high clouds that thickened over the mountains and lower deserts this afternoon, have all but disappeared. At 9 PM PDT...lower marine stratus was gathering over the CA Bight and beginning to spread back inland. Our 00Z Miramar sounding had a 6C inversion based near 1250 FT MSL. This was down about 600 FT from yesterday evening. There was a considerable moistening above 12K FT as well, but the mountain-top layer remained exceedingly dry. Onshore sfc pressure gradients from the coast to the deserts were stronger than yesterday, and that has resulted in peak westerly wind gusts again near the passes of 35-40 MPH. No forecast updates are planned this evening. From previous discussion... Our shallow marine layer will keep coastal cloud coverage rather coastal this coming week, and a strong marine inversion should make a few clouds stick along the immediate coast during the days. High pressure over Colorado will migrate westward over Utah and strengthen for this coming week. That will maintain our hot inland weather and our shallow marine layer. Temps will be near normal near the coast under the influence of the marine layer, but a few degrees above normal for valleys, mountains and deserts for pretty much this entire coming week. The ridge axis of our western high will migrate slightly northward Tuesday and Wednesday, opening the door for monsoon moisture in Mexico to move into SoCal. The moisture is not deep and somewhat high, not super favorable for precip. But there is enough moisture to warrant the slight chance forecast of showers and thunderstorms, most likely in our mountains Wednesday and Thursday. Recent runs of ensemble guidance has shown a decent consensus in backing off the monsoon moisture beyond Thursday. The added surface humidity Wednesday and beyond will add to the heat risk for inland areas, particularly the desert, even if the temperature trend stays flat. That higher heat risk might be felt more acutely during very warm, muggy nights pushing 90 degrees in the lower deserts. Overall, this is rather seasonal, typical weather for July with nothing too anomalous or hazardous this coming week. && .AVIATION... 100320Z...Coast/Valleys...FEW with bases 1000-1400 FT MSL are beginning to develop across coastal areas. More widespread development is expected after 06z Sun. Bases may lower after 10z Sun with bases 700-1000 FT MSL possible, including vcty KSAN, KCRQ and KSNA. Local vis reduced to 1-3 SM where low clouds and terrain intersect. Scatter out 16-18z Sun. Mountains/Deserts...Mostly clear with unrestricted vis through Sun. Local W-NW wind gusts of 20-30 knots possible across the mtns/desert slopes through 12z Sun, with areas of WK-MOD up/downdrafts. && .MARINE... No hazardous marine weather is expected through Thursday. && .SKYWARN... Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. && .SGX WATCHES/WARNINGS/ADVISORIES... CA...NONE. PZ...NONE. && PUBLIC...10/MM AVIATION/MARINE...Schenk
