The National Weather Service (NWS) in San Diego has indicated a warming trend is on the horizon for Southern Californians as high temperatures are expected to increase through the middle of the week. In particular, the valleys could see a temperature hike of 5 to 10 degrees today, peaking on Wednesday before settling to seasonal averages. Coastal areas will not be spared from the heat either, with an increase of a few degrees anticipated by midweek, according to the NWS San Diego forecast.
Wednesday's forecasted highs look quite diverse across the region, as the coastal towns brace for 70s, and the Inland Empire sees the mercury reaching into the 90s. At the same time, the lower deserts might endure a scorcher with temperatures ranging from 106 to 112 degrees. The familiar dance of night and morning coastal low clouds will continue to thread through portions of the western valleys late each night, which could potentially cool things down, especially as the marine layer plays between 1500 and 2000 feet deep. This was detailed in a statement from the Area Forecast Discussion from the National Weather Service San Diego CA.
Looking ahead to the weekend and early next week, the weather pattern appears to stabilize slightly. The NWS predicts "onshore lower-level flow and dry southwest flow aloft will continue," meaning that temperatures will not waver far from the average, granting residents a reprieve from extreme weather deviations. As mentioned by the NWS discussion, these conditions are expected to persist through Sunday, with the daily ritual of night and morning coastal low clouds spilling into the valleys.
Marine conditions also look favorable, with the NWS forecasting clear sailing - no hazardous marine conditions are expected through Sunday. Skies over the Inland Valleys, Mountains, and Deserts are set to stay mostly clear as VFR (Visual Flight Rules) conditions prevail into Wednesday morning. While Skywarn activation is not necessary, the NWS encourages weather spotters to remain vigilant and report any significant weather patterns that may develop. More information on these forecasts can be gleaned from the NWS marine and aviation outlooks.
