The rain Long Island received Saturday was welcome as the region has been dry of late.

"We have actually been drier than normal since April," News 12 Long Island meteorologist Samantha Augeri said. "We do need the rain, and the rain we received [Saturday] only put a little dent in our deficit."

Augeri added: "May was off to a cool start but we've had quite a few warm days recently . . . for the month so far we are 5 degrees warmer than normal. It feels more like summer again today."

Will it be warm enough to hit the beach for Memorial Day?

"It's typical this time of year for our beaches and the East End to be a little bit cooler any time we get a wind off the water or sea breeze," Augeri said. "However, the water is actually beginning to warm up a little bit with buoys reporting temps near 55 degrees. That will help us out a little bit going forward."
