The bleak, brown and gray Berkshire landscape may be transformed into a winter wonderland this weekend with the expected arrival of the season's first significant snowfall.

Forecasters are keeping a close eye on a series of storm systems that could unleash multiple outbreaks of snow, sleet, ice and rain between tonight and Tuesday.

Mild air that sent readings into the low 50s on Thursday will be pushed out today, as temperatures drop into the 30s, according to meteorologist Alex Sosnowski. He predicted rain mixing with and then changing to snow after dark before ending Saturday morning. One to three inches of snow could lead to slippery roads in the Berkshires and surrounding areas.

At the National Weather Service in Albany, N.Y., meteorologist Tom Wasula, citing a "complicated forecast," predicted a changeover from rain to sleet and freezing rain toward nightfall today. That may be followed by a "decent burst of snowfall" of 2 to 4 inches. But first, there's the possibility of up to an inch of sleet, as well as light ice accumulations in the Berkshires south of the MassPike.

"The weekend ends on a tranquil note, then winter comes in like a lion" late Sunday, the government forecaster stated. Two storm systems will aim at the Northeast at the same time -- one from the southern Rockies and the other from the Gulf region. End result: a "high likelihood of a wintry mix Sunday night and Monday" followed by a sharp cooldown with snow showers on Monday night.

By Tuesday night, temperatures may drop below 10, with daytime highs struggling to get above 20.

At Pittsfield Municipal Airport, only a half-inch of snow has been measured since Nov. 1, compared to a season-to-date average of 8 inches.
