Long Islanders might finally feel like spring is in the air this week after a cold start Sunday that is expected to reach a high of only 46 degrees, forecasters said.

“The temperatures will be more normal for this time of year,” said Faye Barthold, a meteorologist for the National Weather Service at Upton. “Normally the high is in the mid-50s and the low is right around 40.”

According to a News 12 forecast, Sunday will be a mostly sunny but it will become increasingly cloudy in the evening when the low is expected to dip to 37.

On Monday, mostly cloudy skies are expected to start the workweek but the bright side is the high is to warm up to 54 and the low will be in the upper 40s. “Overnight there’ll be a 20 percent chance of rain,” Barthold said.

“We’ll go from winter to spring in the next 24 hours so that’ll be a welcome change,” News 12 meteorologist Matt Hammer said. “There’ll be April showers more often than not, but by the end of next week, we could actually approach the mid-60s.”

On Tuesday, definitely pack an umbrella, although the high will be 55. “There’s an 80 percent chance of rain starting in the morning across western parts of the island and spreading east about noon,” Barthold said. “There’ll be between a quarter and a half an inch.”

Lows in the mid-30s are predicted at night, and the chance of rain continues into evening.

The rain is expected to clear out Wednesday, when it will be mostly sunny and highs are expected in the low 50s. Lows will be in the mid-30s.

Thursday will be another sunny day with highs in the mid-50s. Lows at night will be around 40 for the most part and in the mid-30s in cooler locations, like the Pine Barrens, Barthold said.

Lots of sun continues into the start of the weekend, when highs are expected in the mid-50s and lows in the lower 40s.

“This week definitely looks more seasonable,” Barthold said.

But when asked if spring has finally sprung, Barthold said, “We’ll see.”
