(Bloomberg) — A cold rain fell on New York City Tuesday as a fast-moving winter storm brought heavy snow to the north and east, causing airline delays and potentially snarling ground traffic across the interior Northeast. Temperatures in New York hovered around 40F (4C) by midday, with more than half an inch (1.3 centimeters) of rain expected in the coming hours, according to the National Weather Service. Meanwhile, the central Hudson River Valley and much of New England braced for six to 10 inches of snow, with up to a foot possible in some places. Periods of rain and heavy snow are forecast to hit some major highways across the region, creating difficulties for air travelers in larger cities. Heading into Tuesday afternoon in New York, 3,184 flights in the US were delayed, with another 146 canceled, according to FlightAware. Winter weather advisories and storm warnings late Tuesday morning extended from North Carolina to Maine’s border with New Brunswick as the system is forecast to track north along the coast. A yellow snowfall warning – indicating a moderate impact – has been issued across much of Nova Scotia, as well as southern Ontario, by Environment and Climate Change Canada. “All the major cities are missing it today,” Bob Oravec, a senior branch forecaster at the US Weather Prediction Center, said of the storm’s biggest impacts. “It’s moving pretty fast. Even though it will snow hard today, it won’t be a storm that lasts forever.” In New York City, the rain is forecast to taper off late Tuesday, and Wednesday will be sunny with a high of 41F (5C) expected before a flurry of colder air arrives later in the week. Thursday night’s low is expected to drop to 20F. Boston will likely see snow overnight, turning to slush early Wednesday morning as gusty winds sweep the city. Oravec said that icy air will push into the Great Lakes as the storm exits, and some of it will come east. Temperatures in Chicago are forecast to drop to 4F Thursday night, he said. There is a chance that many cold records will be tied or broken on Thursday and Friday at more than 70 weather stations across the region. (Updates with details throughout.)
