Winter weather whiplash is slamming a huge part of the country as more than 240 million people are under winter warnings, watches and advisories. The National Weather Service has issued winter weather advisories for nine states in that region, including Pennsylvania, New Jersey, New York, Massachusetts, Rhode Island, Connecticut, Vermont, New Hampshire and Maine. Rain is likely in New York and Washington, DC, but the temperatures won't drop below freezing, the weather service predicts. The National Weather Service station in Burlington says icy roads should be expected Monday afternoon and Tuesday morning. "Slow down and use caution while traveling," the weather service said.

(CNN) - A wet spring in Las Vegas has spawned hordes of grasshoppers so large, they're showing up on the weather radar. In viewing the radar, CNN meteorologist Allison Chinchar said it looked like there were two storms over the Vegas area: one north of the city (that was actual rain) and another right over Las Vegas. "It looked as though it should be torrentially downpouring in Las Vegas," said Chinchar. The National Weather Service office in Las Vegas said in a tweet Saturday that people have been asking about "the widespread radar returns" in the city over the past few nights. Las Vegas, like all of Nevada, has had almost twice as much rain in 2019 than normal, Chinchar said.
