Unseasonably warm weather set records in some parts of San Diego Monday and on Christmas, but a winter storm and cooler temperatures are coming, the National Weather Service reported. "We're going to get weak storm systems coming in with atmospheric rivers that will be getting here late Tuesday night into Wednesday," NWS forecaster Adam Roser said. "They are going to be weak, so the rain will be beneficial and won't be too heavy." Roser predicted the rain total from the incoming storm is likely to be three-quarters of an inch to an inch in some places. "Along with that, we are going to be getting cooler weather, in the 60s instead of the 80s during the day," Roser said. "It is also looking like we will be getting some random light showers as well on Thursday and Friday." The longer-term forecast is for the weather to turn wet again for New Year's weekend. "Maybe we'll see another inch of rain or so across parts of San Diego," Roser said. Find the latest weather forecast here: https://www.cbs8.com/weather/
