Wednesday is set to bring cooler temperatures near the coast, around a few degrees less than today and up to 5 degrees cooler inland. As for high temperatures, inland valleys of San Diego County could see up to the 90s, and Orange County could experience up to around 90 degrees for far inland areas. The lower deserts anticipate 105 to 110 degrees, a slight drop from today's scorching highs of 110 to 115 degrees.
Monsoonal moisture in the region is increasing and may lead to a 10 to 20 percent chance of thunderstorms this afternoon for the mountains and deserts of Riverside and San Diego counties, as detailed by an Area Forecast Discussion from the National Weather Service. An easterly wave moving to the south is expected to draw in more moisture late tonight into Wednesday, heightening the potential for thunderstorms, most noticeably for tomorrow afternoon. An Excessive Heat Warning is in effect until this evening for several valleys and deserts, with a Heat Advisory for areas including the Riverside County Mountains and San Diego County Valleys.
Looking ahead, the forecast suggests a slight cooling and drying trend into next week following another chance of thunderstorms over the coming weekend. Coastal regions will continue to experience patchy night and morning low clouds, extending locally inland and potentially affecting visibility in the valleys and higher coastal terrain. Meanwhile, no hazardous marine conditions are anticipated through Sunday, making for safer conditions for those looking to escape the heat on the water.
