Arctic air, snow squalls move in later Wednesday

The arrival of arctic air is being accompanied by snow squalls moving from west to east across Massachusetts.

“These squalls could reduce visibility down to near zero and produce very gusty winds during a very brief amount of time,” StormTeam 5 chief meteorologist Harvey Leonard said.

Snow squalls are much like summertime thunderstorms – they are quick hitting and can produce a lot of precipitation in a very short amount of time.

The squalls should move through eastern Massachusetts and southern New Hampshire between 3-7 p.m. from west to east.

After the squalls, temperatures will rapidly plummet into the single digits during Wednesday night. Wind chills will drop to -20 to -30 by Thursday morning.
