Thursday storm expected to bring at least 6 inches of snow

The arctic plunge is set to begin today and continue through this week, bringing abnormally low temperatures from the north and the first snow storm of 2014 by the end of the week.

“We’ll have a couple days of abnormally cold weather, averaging 10 degrees colder than normal,” said National Weather Service meteorologist Bill Simpson, who said a snow storm is due to arrive on Thursday.

Today will be mostly cloudy with temperatures in the upper 30s. That number will plummet to 28 degrees by 5 p.m. with the arrival of arctic air from Canada.

Tuesday will be mostly cloudy and even colder, with highs in the low- to mid-20s and wind chills in the teens. Snow is expected to develop in Western Massachusetts in the afternoon, with flurries throughout the state. That will gradually clear out as temperatures drop to the mid teens.

New Year’s Day will be mostly sunny but cold with a high near 26 degrees, dropping into the teens in the evening, with a slight chance of snow after 1 a.m. Thursday.

A storm system is expected to move in Thursday and continue through Friday morning. The snow is expected after 9 a.m. on Thursday and continuing throughout the day, creating possible problems for commuters.

Simpson said its a “safe bet’’ that snowfall will total six inches and above. He said more precise snowfall estimates will be generated as the storm nears the region.

Friday will also be very cold, with a high in the mid teens and dropping to 2 degrees in the evening. The snow is expected to clear out by Friday morning, with dry weather conditions in the evening and throughout the weekend.
