Locals still glowing from some of the nicest weather in the nation had a bit of a wakeup call Tuesday with cooler temperatures arriving and rain likely on the way. Tuesday is expected to be cloudy and cooler with a slight chance of a shower later in the evening. The prospect of precipitation, however, goes up early Wednesday morning, with showers expected to approach before sunrise, and heavier rain likely arriving for Wednesday morning’s commute, forecasts NBC 7 meteorologist Sheena Parveen. “A low-pressure system from the west will bring showers and a slight chance of thunderstorms for late [Tuesday] and Wednesday,” the National Weather Service said in its most recent forecast. “There will be strong south winds [Tuesday] afternoon through Wednesday morning along and below the desert slopes of the San Bernardino County mountains with gusts to 45-55 mph and isolated gusts to 65 mph.” Rain totals could be in the neighborhood of a quarter-inch but some areas may get a half-inch or more, Parveen said. Wednesday afternoon looks to be drier and cloudy. There is a slight chance for a shower on Thursday, with lingering moisture, Parveen said. So far, Friday and the weekend look dry with seasonable highs, which will be cooler than what we’ve seen lately. Some computer models are showing slight rain chances on Sunday, although others keep us dry until Monday. Next week’s storm system looks cooler, with more rain for Southern California possible and a chance of wintry weather in our mountains. ...read more read less
