A low pressure system over the Great Basin will continue to lead to stronger onshore winds across southern California along with a fairly deep marine layer. Strong and gusty west winds will impact the mountains and deserts late this afternoon through early Thursday morning. An upper ridge will gradually build into the area from the northwest through the weekend. This will lead to significant warming and more sunshine heading into the weekend and into early next week.
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... -Forecast Highlights-
* Strong west winds mountains/lower deserts through Thu morning * Gradual warming trend through early next week
West winds will again strengthen late this afternoon and evening along the desert mountain slopes and across the lower deserts. Winds through the San Gorgonio Pass continue in the 40-50 mph range. Expanded the Wind Advisory and extended the advisory in time, through 2am Thursday. The advisory covers more of the Coachella Valley. Wind gusts up to 50 mph is forecast, especially from north Palm Springs to Thousand Palms. Gusts to 65 mph could occur on the desert side of the San Gorgonio Pass this evening.
The cool weather pattern of late will be changing as the upper low moves away from the region and an upper ridge gradually builds in from the northwest. Winds will become offshore this weekend with weak Santa Ana winds expected. Significant warming will occur especially late this weekend and early next week as heigheights rise. Dry weather along with abundant sunshine will prevail, aside from the next few mornings near the coast as marine layer stratus will continue there over the next few nights. It should be mostly clear though this upcoming weekend.
Forecast confidence lessens by the middle part of next week. GEFS shows mean upper ridging continuing over the area, while the EPS shows an upper low developing and moving south across CA/NV. This would lead to cooling with even the potential of more drizzle and a deepening marine layer. Either way, no significant precipitation is expected through next week with much warmer conditions expected this weekend into early next week, which could trend slightly cooler mid next week.
No hazardous marine weather is expected through Monday.
.SKYWARN... Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
