Syracuse, NY – Sunday was the hottest day of the year so far, hitting 75 degrees in Syracuse. But residents of central New York shouldn’t count on the summer weather to stick around.

Temperatures could drop as low as 20 degrees – a drop of 55 degrees – later this week, according to forecasts from the National Weather Service.

Sunday’s high of 75 degrees shattered the previous March 6 record, set in 1946 when it hit 67 degrees. Typically, it’s around 39 degrees this time of year, according to weather service records. Last year, the high temperature on March 6 only reached 24 degrees, records show.

Residents of central New York enjoyed the sun on Sunday, going for bike rides, walks and playing outside. Many wore T-shirts and shorts as it felt like summer.

Temperatures are expected to drop to around 37 degrees overnight. By the morning, rain will likely arrive, along with a mix of snow and sleet north of the Thruway, according to the weather service.

The forecast calls for a high temperature of 47 degrees on Monday. It will rain at times, but by Monday evening “the precipitation is expected to subside and cold air will come in and change the rain to a mix of rain and snow before changing to all snow with a light snow accumulation at lake effect southeast of Lake Ontario overnight,” the weather service said.

There is now a 60% chance of snow on Tuesday. It will also be even colder, with a high of 37 and a low of 25, according to the forecast.
