It may be spring but it won’t feel like it for the next couple of days.

After mild weather on Tuesday, it’s “back to winter tomorrow and much colder,” News 12 Long Island meteorologist Rich Hoffman said.

Tuesday’s “very mild temperatures” are to be “followed by very cold temperatures for tonight through Wednesday night following the passage of a strong cold front,” the National Weather Service said in its regional weather summary. And, look for “winds really picking up late tonight through much of Wednesday night.”

Indeed, given high wind gusts and low relative humidity, a hazardous weather outlook has been issued for Wednesday, warning of the enhanced risk for brush fires to spread, should any start, the weather service said. The outlook is in effect for all of the Island, except northern Nassau County. Winds from the northwest are expected to be 15 to 25 mph, gusting up to 35 to 40 mph.

Tuesday, the second day of spring, brought partly sunny skies, warming up to the mid 50s, as forecasters had indicated.

At before 2 p.m., the temperature at Long Island MacArthur Airport was 55 degrees, with winds of 12 mph, shifting to come from the southwest.

Lows overnight Tuesday are about 30 degrees, heading up only to around 35 degrees for Wednesday, Hoffman said. The day is to be “mostly sunny, windy and cold.”

Then, it’s down to about 17 degrees for the overnight hours, and up to highs Thursday of 35 to 40 degrees.
