Hot conditions will continue into mid-next week, peaking Monday and Tuesday. Isolated showers and thunderstorms over the mountains this afternoon and potentially again Wednesday afternoon. Gradual cooling is expected for the latter half of the week.
For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
Forecast Highlights: *Hot conditions through Wednesday, peaking Monday and Tuesday, with widespread moderate to high heat risk. *Isolated thunderstorms this afternoon in the mountains and a 15-20% chance Wednesday afternoon.
A few isolated showers and thunderstorms have developed over the mountains as of 1pm this afternoon. Isolated showers and thunderstorms will continue to develop through this afternoon, before diminishing around sunset. Drier air and subsidence from the upper level ridge should suppress any precipitation chances for Monday and Tuesday. As the ridge breaks down on Wednesday with the trough passing to our north, a slight chance of showers and thunderstorms is again possible over the mountains. There is low confidence at this time, but global models continue to show ensemble members with precipitation. The current forecast follows the NBM with 15-20% chances in the mountains Wednesday afternoon.
For Monday and Tuesday with the upper level ridge settled over the Great Basin, hot conditions are expected to continue. High temperatures Monday and Tuesday are expected to be 10 to 15, locally up to 20 degrees above average west of the mountains. In the deserts, highs will be 5 to 10 degrees above average. Widespread moderate to high heat risk is expected, with highest heat risk in inland Orange County and the Inland Empire. For the latter half of the week, an upper trough will lead to a gradual cooling with highs returning to near the seasonal average by next weekend.
Wind gusts near 20 kts across the outer waters and near San Clemente Island during the afternoons and evenings today and Monday. Otherwise, no hazardous marine weather is expected through Thursday.
Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
