Los Angeles is preparing for a cooling trend starting this Monday, with anticipated rain by the week's end. ABC7 Los Angeles reports a drop in temperatures as a weather system moves in, bringing cooler air and more cloud cover. This follows a period of warmer weather, so residents should prepare for noticeable changes. Rain is expected later in the week, potentially disrupting outdoor activities and commutes. This cooling trend is part of a broader pattern affecting Southern California, with similar conditions predicted for Orange County and the Inland Empire.
