Area Forecast Discussion National Weather Service San Diego CA 925am PST Thu Jan 23 2025 Synopsis Critical fire weather conditions will continue through Friday morning. The strongest Santa Ana winds are expected into the afternoon, with single digit relative humidity values. For the weekend into early next week, a cold low pressure system from the north is expected to bring cooling with widespread showers and mountain snow for Sunday through Tuesday. There is even a slight chance of thunderstorms for Sunday, and potentially Monday. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties Gusty northeast winds will continue through the morning and slowly weaken into the afternoon. So far peak gusts have been in the 70 to 80 mph range. Hauser Mountain in San Diego County gusted to 77 mph and Freemont Canyon in the Santa Ana mountains gusted to 75 mph. The one outlier is Sill Hill a very wind prone location in the San Diego mountains, which has gusted to 91 mph today. A wind gust summary has been headlined on our weather.gov/sandiego homepage if you're interested in seeing additional sites. Winds will gradually decrease through the day, but remain elevated overnight. Critical fire weather conditions will continue into Friday morning due to the combination of elevated winds and very dry conditions. High temperatures for the coast into the valleys will be even warmer today than Wednesday, mostly in the 80s for the coast and western valleys with the warmest locations near 90. High temperatures near the coast will be much cooler on Friday, but still around average. Cooling will continue to spread inland on Saturday with Saturday high temperatures mostly in the mid 50s to mid 60s for the coast and valleys. We're continuing to monitor a change in the weather for the weekend into early next week. A slow moving low pressure system will move near Point Conception late Sunday afternoon, dig south into Southern California by Monday, and depart to the east on Tuesday. There remains some uncertainty in the current timing of the precipitation, but it looks like the bulk of the precipitation will fall Sunday into Monday. Precipitation has the potential to continue into Tuesday, although right now it looks like the precipitation will become less widespread. A chance of thunderstorms is currently in the forecast for Sunday, and there is a potential that chance will expand to Monday with the afternoon update. This is expected to be a cold system, with snow levels starting at to 4000 to 5000 feet for Saturday night into Sunday, then fall to 3500 to 4500 feet for Sunday night and 3000 to 4000 feet on Monday. NBM probabilities of receiving one inch or more of rainfall/liquid- equivalent for the weekend are generally 65 to 75 percent from the coast to the mountains with a 60 percent or greater chance for three inches or more of rainfall/liquid- equivalent for the typically wetter mountain locations. For the mountains, there is a 70 percent chance of receiving 12 inches or more of snowfall above around 7000 feet. There is also a slight chance of thunderstorms, mainly for the coast to the mountains for Sunday afternoon and evening, potentially again on Monday with the potential for higher-intensity rainfall. It does look like snow levels will remain low enough through the duration of the event to limit the flooding potential in the mountains. There is a 35 to 50 percent chance of one inch or more of snow falling in the High Desert, with chances locally up to 85 percent in the higher elevations of the High Desert region. High temperatures for Sunday and Monday will be as much as 15 to 20 degrees below average for the higher mountains with high temperatures for the coast and valleys mostly in the 50s and lower 60s. Dry conditions are expected to return by Wednesday with below average temperatures expected through Thursday. Marine Offshore winds with isolated, occasional gusts approaching 20kts expected through early Friday. There is a slight chance of thunderstorms Sunday, any of which could produce locally gusty, erratic winds, lightning, and briefly hazardous conditions. Otherwise, prevailing winds and seas are not expected to generate hazardous marine conditions today through Monday. Fire Weather Critical fire weather conditions will continue through Friday morning. The strongest winds are expected through this afternoon with northeast winds 35 to 45 mph with gusts 60 to 75 mph and with isolated gusts to 85 mph for the San Diego County mountains. Lowest humidity will fall to 5 percent or less today with poor recovery to 5 to 15 percent tonight. For the weekend into early next week, a cold low pressure system from the north is expected to bring cooling and a substantial recovery in humidity. Widespread wetting rainfall with snow in the mountains is expected for Sunday and Monday. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
