NEW YORK (AP) — Falling temperatures could lead to icy conditions on roads and sidewalks across the Northeast following a late-season storm that plastered the region with sleet and snow.

The powerful nor'easter paralyzed much of the Washington-to-Boston corridor, but fell short of predicted snowfall totals in New York, Boston and Philadelphia.

The storm, which followed a stretch of unusually mild weather, dumped 1 to 2 feet in many places, grounded more than 6,000 flights and knocked out power to nearly a quarter-million customers from Virginia northward.

By the time it reached Massachusetts, it had turned into a blizzard, with near hurricane-force winds gusting to over 70 mph along the coast.

Plunging overnight temperatures threatened to turn the snow, sleet and sloppy mix into a slippery mess.
