The storm that walloped the state today has let up somewhat, but it’s not completely over, National Weather Service forecasters say. It’s going to linger into tonight.

The snow, which is already a foot deep in some areas, is expected to gradually change to rain and freezing rain east of Interstate 95, turning roads treacherous.

After a brief break, interior portions of Massachusetts could see an additional 1 to 2 inches of snow, the forecasters said.

Strong winds are expected this afternoon on the coast, gusting up to 50 miles per hour and potentially bringing down tree limbs and power lines.

When the whole mess is over, 2 to 4 inches of snow are expected to have dropped in Boston. Amounts taper away to the south and east, with less than an inch on the Cape. But the amounts ramp up quickly as you head west, with 6 to 8 inches expected to fall in some areas inside Route 128 and 8 to 10 inches falling in some areas between Route 128 and I-495. In far Western Massachusetts, up to 24 inches is expected in some areas, according to a weather service snowfall forecast map issued this afternoon.

By 3 p.m. a foot of snow was on the ground in Ludlow, the highest total in the state.

Hundreds of schools across the state were closed today. Governor Patrick canceled work for all non-emergency executive branch employees in Berkshire, Franklin, Hampshire, Hampden, and Worcester counties. A number of state courthouses were also closed early.

The Massachusetts Department of Transportation said late this afternoon that it had deployed 2,604 crews to treat and plow state roads, according to a department tweet. The speed limit on Interstate 90 was reduced to 40 miles per hour between Weston and the New York state line.

“All the roads are a mess, especially the Mass. Pike and I-495,” Lt. Daniel Richard, a State Police spokesman, said late this afternoon. “You have to reduce your speed, and give yourself more time to get where you are going. ... If it appears too hazardous to drive, then don’t.”

He said multiple spinout accidents had been reported, but no serious injuries.

A snowplow and an ATV collided on Route 112 in the Western Massachusetts town of Huntington, resulting in two injuries. In Chelsea, adjacent to Boston, the driver of a car and a city fire truck were both taken to the hospital after a crash that police said they suspected was snow-related.

The MBTA said all bus routes were experiencing delays due to the inclement weather. The public transit agency also reported problems with some Green Line trains.

Just over a quarter of today’s scheduled flights to and from Logan International Airport had been canceled as of 7:30 a.m., the Globe reported. Amtrak said it would operate the Acela Express and Northeast Regional trains on modified schedules.

Skies will gradually become sunny Friday as highs rise to 37 degrees. Clouds will start rolling in during the afternoon as temperatures drop into the mid-20s.

What’s next after that? More snow.

Snow should start falling again Saturday after 4 a.m., with cloudy skies and highs near 35 degrees.

“We’re going to have a small gap in the storm late Friday night before we start seeing some more snow on Saturday, with probably an inch or two more in Boston,” said weather service meteorologist Bill Simpson.

Any snow should clear out before 10 p.m. as temperatures sink into the upper teens.

Sunday should be dry and frigid, with lots of sunshine and highs in the mid-20s throughout the day. Temperatures should plummet into the single digits overnight, bringing a chance of some light snow Monday morning.

“We’ll start cooling off for a couple days and we’ll see a gradual warmup next week,” Simpson said.
