And you thought Saturday was nippy.

With a high of 26 degrees forecast on Long Island, Sunday should be the coldest day so far of an unusually warm winter, the National Weather Service said.

Overnight lows were expected to be in the single digits.

People should bundle up if they venture outside, meteorologist Mike Layer advised.

"Warm hats, scarves, gloves," he said.

Still, Sunday's frigid temperatures will come nowhere near a daily record. In 1965, the mercury dipped to minus 11 degrees at the Brookhaven National Laboratory in Upton.

So far this winter, overall temperatures have been above normal, without a trace of snow.

High temperatures on Long Island this winter bounced from 28 degrees on Jan. 4 to a balmy 61 degrees just three days later, both recorded in Islip.

The historical average temperature for January in Upton is 38 degrees, and the average high is 47.

After Sunday's freeze, the forecast for the region calls for a return to high temperatures in the high 30s to mid-40s over the next few days.

And no snow is in the forecast for at least the next 10 days.

Last January was the snowiest on record for Long Island.
