NEW YORK (CBS New York) -- A wintry mix of snow and sleet is causing massive delays, and is making travel tricky across the Tri-State Area.
While the white stuff started coming down during the morning rush on Wednesday, the worst of this latest storm started at night, as much more accumulating snow began to blanket the region.
The National Weather Service issued Winter Storm Warnings until 6 a.m. Thursday, and conditions aren't expected to improve until after the morning commute.

Snow began falling heavily on parts of the are in the middle of the morning rush hour on Wednesday. Local streets quickly became snow-covered, although the major roadways remained passable.
Intermittent snow, sleet and rain fell most of the day. A second barrage of steadier and heavier snow started late Wednesday evening, and will carry into the early morning hours on Thursday.
"The biggest part of the storm is with us while you're sleeping," CBS 2 meteorologist Lonnie Quinn said.
The bulk of the snow will exit overnight, but Thursday morning's commute will be very messy.
"By the time you get to about 4 a.m., things really taper off in the city," Quinn said.
The FAA announced Wednesday that the weather was causing significant arrival delays at New York's La Guardia Airport, as well as Newark Liberty Airport in New Jersey.
The National Weather Service said significant snowfall was forecast for the New York metropolitan area. Accumulations of up to 14 inches were forecast for the city, with up to 12 inches in Westchester County and northern New Jersey.
In New Rochelle, minor coastal flooding is possible late Wednesday night. The National Weather Service has issued a Coastal Flood Advisory from 1 a.m. to 6 a.m. Thursday.
Once the snow has subsided, Thursday will be a mostly sunny, albeit breezy, day. Temperatures are expected to peak at about 36 degrees. Winds will come out of the northwest at 10 to 15 miles per hour, with gusts reaching 25 miles per hour.
