Bring the umbrella if you’ll be outside on Long Island on Sunday. In fact, it would be a good idea to keep one handy for the next couple of days.

“Wednesday and Thursday — those are the picks of the week to get outdoors,” said News 12 Long Island meteorologist Matt Hammer.

Until then, he said, expect unsettled weather with intermittent rain showers starting on Sunday.

Hammer said there will be spotty rain showers throughout the day, but he said the wet weather won’t put a damper on all of Sunday.

“You can still get out and about — it’s not a complete washout throughout Long Island,” Hammer said. Sunday will start out with temperatures in the upper 30s to around 40, but Hammer said it’s “not too bad for this time of year.”

Melissa Di Spignia, a meteorologist for the National Weather Service’s Upton bureau, said the weather is being dominated by Pacific features moving across the country and impacting Long Island.

Hammer said Sunday will be much cooler than Saturday.

“Those milder temperatures we had to start [Saturday] are now well-suppressed off to the south and west,” Hammer said.

Sunday will also be breezy with winds of about 10 to 20 mph out of the east “making things feel even a little bit chillier,” Hammer said.

Look for highs of 43 in Merrick, Northport and Babylon; and 42 in Westbury, Coram, New Suffolk and Sag Harbor.

Sunday night will be mostly cloudy and breezy with more scattered rain showers and lows near 40 degrees.

The unsettled weather pattern continues into Monday with mostly cloudy skies and periods of rain, but it will be warmer with highs near 53 and the winds dropping off to 5 to 15 mph. On Monday night, scattered showers remain in the forecast with lows about 44.

Mostly cloudy conditions return on Tuesday with the chance for scattered showers with highs near 58 and overnight lows close to 42.

A very early morning rain shower may start off the day on Wednesday before the sun comes out and an early springlike afternoon brings highs near 56. But it will feel like winter again Wednesday night when temperatures dip to about 34.

Mostly sunny skies and highs near 52 are ahead for Thursday with lows about 35.

But the clouds come back on Friday, with highs near 51 and lows around 37.
