Call it "A Tale of Two Snowstorms."
In the Boston area and in Southeastern Massachusetts, a nor'easter arriving Thursday night will likely bring a mere 1 to 3 inches of snow, as warmer air along the coast turns the precipitation into rain, forecasters said.
But in the state's interior, it will be a different story. National Weather Service forecasters today issued a winter storm warning, effective from late Thursday night through late Friday night, predicting 6 to 12 inches of snow in Central and Western Massachusetts.
A weather service snow forecast map issued this afternoon showed areas in northern Worcester County would be hit hardest.
The forecasters warned of a slippery commute and poor visibility on Friday morning in those areas. The wet, heavy snow could also bring down branches and power lines, they said.
The storm is expected to begin late Thursday night, with temperatures low enough so that snow falls over most of the region. But at daybreak Friday, temperatures are expected to rise along the the coast, including the Boston area, and in Southeastern Massachusetts, and the snow is expected to change to rain.
"It looks like it will be too warm on the coastal sites ... to really see a whole lot of snow out of this," said Matt Doody, a meteorologist in the service's Taunton office.
The storm should end by Friday afternoon and evening, the forecasters said.
April Fool's Day, which is Friday, is a notable day for snowstorms because one of the biggest ever recorded in Boston happened on April 1, 1997. That storm dumped 25.4 inches, a number that won't be matched by this storm.
