What they’re saying

“Weak high pressure building over the region will bring a dry and unseasonably warm day on Tuesday, with many southern valleys seeing temperatures reach the lower 60s. This brief period of calm ends Wednesday as a strong cold front moves across the state, bringing widespread rain and mountain snow.”

“Those stronger winds can be dangerous, especially if you're traveling in high-profile vehicles. I'd advise putting away porch furniture until the higher winds die down.”
