NEW YORK (PIX11) -- Snow is already rapidly falling as winter storm advisories have been posted for the entire region. The snow is expected to change over to a mix of sleet and freezing rain just after the evening rush.

Until then, expect 1-2 inches of snow across coastal sections with a little more north and west of the city. The precipitation will eventually taper off to rain showers by midnight

Wednesday will be cloudy and damp with showers from time to time. Eventually, colder air filters in as another low pressure system rides along the front and passes to our south and east late Wednesday night into Thursday.

The system will bring another round of snow into our area and affect the morning commute before it tapers off the afternoon. Roads wills still be slick during the evening rush. Amounts expected are around 2-5 inches around the city and points south. Areas north will get less.

Here is a timeline for the next few days:

3-5 p.m. -- Snow begins

7-9 p.m. -- Changeover to freezing rain

10 p.m.- Midnight Wednesday -- Tapers off to showers

Midnight Wednesday-Midnight Thursday -- Damp and dreary with occasional showers.

Midnight Thursday - 3 a.m. -- Snow redevelops

3-5 p.m. -- Snow Tapers off
