NEW YORK (AP) - The storm that's pounding parts of the Northeast has dropped almost 2 feet of snow in Pennsylvania's Pocono Mountains and the northern reaches of New Jersey, yet it didn't perform to forecast expectations in New York City, the rest of New Jersey and Philadelphia.
That's because the line between a rainy wintry mix and snow ended up farther west than anticipated.
The rain-snow line on Tuesday was a 50-mile wide swath where cold Arctic air from the north and west clashed with warm moist air from the Atlantic Ocean.
Private meteorologist Ryan Maue of Weather Bell Analytics says it's tough to forecast the location of the line, because it undulates and computers models only have a few data points over a width of 50 miles. He also says much of the storm is over the Atlantic Ocean, where fewer observations can be made.
Maue and other experts say missing where the rain-snow line winds up doesn't make the blizzard forecast a bust.
