A daylong gray of rain and drizzle, along with unseasonably cold temperatures, is in store for Long Island on Thursday, the National Weather Service said.

Forecasters on Thursday, in addition to the precipitation, call for daily highs in the mid 40s for most of Nassau and Suffolk counties, significantly colder than normal for this time of year.

"Just another unsettled, chilly weather day," News 12 Long Island meteorologist Samantha Augeri said of Thursday's weather. "Temperatures run a good 10 degrees cooler than normal again today with highs near 46 degrees thanks to a persistent northeast wind."

Augeri said light rain is expected to fall into the nighttime hours, "more in the way of spotty drizzle and mist."

Rain also is likely to be a bit heavier after 4 p.m. and into the nighttime hours, said the National Weather Service's Upton office. Also overnight, patchy fog is likely, and the total rainfall amount is expected to be less than one-tenth of an inch, the service said.

Chance of precipitation Thursday ranges between 30 and 80 percent.

By Friday, a warm front moves in, bringing some clearing Saturday morning. But before skies clear a tad more rain is ahead.

"We're tracking more clouds and a few showers tomorrow," Augeri said about Friday's forecast, "but as the wind switches south and west it will be a little bit warmer, with highs in the upper 50s."

The chance for heavier rain Friday is in the late afternoon and into the evening, she said, likely between 5 p.m. and 9 p.m.

Then the "cold front wipes away the unsettled weather and we get sun with warmer temps for the weekend."

Saturday's daily highs are expected to be in the upper 50s, and on Sunday, Augeri is calling for highs in the low 60s.

If that happens, it would be the first time Long Island has had a 60-degree day since Christmas Eve, when it was 60 at Long Island MacArthur Airport, according to research by the Northeast Regional Climate Center at Cornell University.
