Long Island weather: 'Colder than normal' temps this week, then possible storm

A cold, cold morning was giving way Monday to warming temperatures on Long Island, with expectations for the day to head up to the mid-50s, forecasters say.

The Island is looking at sunny or partly sunny skies through the week, until the weekend brings potential for a coastal storm, with details still iffy at the moment.

By around 11 a.m., Long Island MacArthur Airport in Ronkonkoma was reporting 50 degrees, as was Westhampton, with Farmingdale at 48, the National Weather Service said. Earlier, though, those spots hit lows of 32, 27 and 33, respectively. 

MacArthur's normal low for the day is 43 degrees with 61 the normal high.

Freezing temperatures in Nassau County and western Suffolk mean the growing season is over in those areas, the weather service said. 

Look for “colder than normal temperatures through the week, but most of the workweek will be dry,” said News 12 Long Island meteorologist Rich Hoffman.

Forecasters are not expecting another overnight temperature plunge, as the low to upper 40s -- even 50 degrees in some spots -- are forecast for early morning Tuesday. The day then warms up to the lower 60s, with some areas seeing slight chances of morning showers, the weather service said. 

Wednesday, with mostly sunny skies, was expected to see highs in the mid-50s. Both Thursday and Friday bring sunshine and highs in the mid-to upper 40s.

As for the weekend, meteorologists have their eyes on the potential for a coastal storm to impact the area, though forecast models as of Monday were at odds over timing, strength and track, the weather service said.

Should Long Island end up being affected, the likelihood would be for rain, not snow, said Carlie Buccola, National Weather Service meteorologist in Upton.

The picture should start coming into better focus by mid-week, she said, so do stay tuned.
