A cold front passed through central New York early on Sunday morning, bringing much cooler air and high gusting winds. Now that the front has passed, the cooler air is helping to fire off a few evening showers. Expect that the rain should clear up through the overnight.
With winds steadily out of the west, importing the much colder air, we’re looking at a lake response. East of Lake Ontario and over the Tug Hill Plateau, snow showers will fall during the overnight. With temperatures bottoming out in the low 30s, a couple inches of accumulation is possible over the higher elevations. South of the Thruway however, not much if anything at all is in the forecast other than some wet flakes.
One thing folks south of the Thruway will have to worry about is frost. Advisories are up for Onondaga, Cayuga, Seneca, and Yates Counties through the overnight. Frost is most likely in rural, high elevation areas, so take mind to protect any tender vegetation outside. Temperatures will be bottoming out in the low 30s, and will struggle to rebound during the day Monday. We will be almost 20 degrees cooler than normal for mid May as it will be a struggle to get beyond 50 degrees.
Monday night looks to be another frigid one with lows bottoming out again in the low 30s. This could again cause frost and even hard freeze issues during the overnight. Thankfully, this cold air will begin to pull out on Tuesday during the daytime. A push of warmer air heads our way by midweek. As it does, though, we will run the risk of a new round of showers and thunderstorms.
