San Diegans weathering the unusually cool temperatures can look forward to a gradual warm-up in the coming days. According to the National Weather Service San Diego, the high temperatures today will stay below the norm, 5 to 15 degrees below average inland, and approximately 3 to 5 degrees cooler near the coast. The forecast promises a shift starting Sunday, with highs creeping a few degrees above Saturday’s chilly numbers.
The additional rainfall expected through tonight will primarily affect the deserts and the mountain slopes adjacent to them. Occasional showers might slip past the mountains, but any significant downpours are predicted to remain confined to the desert regions. "Widespread light precipitation has developed over the deserts with a few light showers also wrapping around from the north," states the National Weather Service in their recent Area Forecast Discussion. Snow levels are expected to rise from the current 6500 ft to 7000 ft later this morning.
As the precipitation tapers off by this evening, dry conditions are anticipated for Sunday. The wind isn’t letting up just yet, though, with gusty northeast to east winds, particularly strong through this evening around the coastal mountain slopes and below the passes. Some areas might experience gusts of up to 45mph, according to the discussion notes. By midweek, a warming trend is expected to bring temperatures back to the above-average range.
Looking ahead, a weak Santa Ana event is forecast around mid-week, likely contributing to increased temperatures. "There is a 15% chance of a moderate event on Wednesday," the National Weather Service San Diego reports. However, beyond Thursday, the predictability of the weather becomes murkier, with a potential cooling trend and the approach of another upper-level trough introducing uncertainty in precipitation chances heading into next weekend.
