Don’t let today’s spring-like feel fool you. Tonight the weather will turn wintry again.

Rain will arrive in the region this evening, then mix with snow, and change to light snow north and west of the Massachusetts Turnpike and Interstate 495, the National Weather Service says. Overnight lows are expected to be into the low to mid-30s.

The snow will continue in northern areas into Friday. One to 2 inches are expected to fall north of the Pike and in the southern Berkshires. Two to 4 inches may fall in areas north of Route 2. Up to 5 inches are expected in the northern Berkshires. The snow will be heaviest over the higher elevations, the agency said.

The weather service issued a winter weather advisory this afternoon for Franklin County, western Hampshire County, and northern Worcester county, warning of slippery roads and potentially decreasing visibilities.

Areas south of the Pike will have rain. Areas along the southern coast, including Boston, are expected to see little or no accumulation, the agency said. Temperatures are expected to rise to the mid-30s to low 40s.

“It’s a pretty weak system that’s moving right along the coast, and it’s going to be moving through pretty fast, so it won’t really have a chance to give us too much snow,” said Matt Doody, a meteorologist in the agency’s Taunton office.

On Friday night, the rain-snow mix is expected to dwindle and disappear by daybreak, though Southeasern Massachusetts might see a late changeover to snow, as lows drop into the 20s.

Saturday will be cold, with highs only in the low to mid-30s. But it will be sunny in the western area of the state, while mostly cloudy in eastern area, the weather service predicted.
