BOSTON (AP) — Forecasters are watching two weather systems that may bring significant snow in the coming days, just as New Englanders are digging out from a historic blizzard.

A storm arriving in the region late Thursday and lasting off and on through Friday night will most likely bring 2 to 4 inches of snow to Connecticut, Rhode Island and Massachusetts, said Frank Nocera, a senior meteorologist at the National Weather Service.

Eastern Massachusetts, including Boston and Cape Cod, has an "outside chance" of seeing up to six inches — adding significantly to the 2 to 3 feet of snow already dumped in parts of Massachusetts earlier this week, Nocera said.

Forecasters are also monitoring a storm heading into the region over the weekend.

Depending on how it tracks, that storm could bring several more inches of snow — or snow turning into rain — from late Sunday into Monday in Connecticut, Rhode Island and southeastern Massachusetts, Nocera said.

But, he stressed, it's still too early to say for sure what Sunday will bring.

"There's still some uncertainty," Nocera said. "Neither storm will be close in magnitude to the one we just had, but there's really no place to put additional snow. Even 2 to 4 inches will be an inconvenience."

Meanwhile, the National Weather Service warned of bitter cold temperatures in the coming days.

Single-digit temperatures were forecast for Wednesday night. On Saturday, wind chills could make it may feel as low as minus-5 degrees Fahrenheit across southern New England.

During the blizzard that pounded New England Monday and Tuesday, the central Massachusetts city of Worcester saw a record 34.5 inches, according to the National Weather Service.

Boston saw just over 24 inches, and Providence, Rhode Island, had about 19 inches.
