NEW YORK CITY — Tuesday's morning commute could be fraught with dangerous blizzard conditions that may make some roads impassible as winds of up to 50 mph create whiteout conditions, forecasters predicted.

By the end of it all, the storm is expected to dump as much as 20 inches on the city, according to National Weather Service forecasters. And even when it's done, the snow will probably stick around as temperatures will stay below freezing until later in the week, forecasters said.

Here's what to expect, hour by hour, according to forecasters:

TUESDAY

► Midnight — Snow is set to begin falling after midnight. A state of emergency has been called by both the city and state to begin at 12:00 a.m. 

► Overnight temperatures will bottom out at 31 degrees and stay there through the morning.

►4:30 a.m. The LIRR and Metro-North will announce service suspensions. 

► 6 a.m. — "The period of intense snow will probably start around 6 a.m.," said NWS' Melissa Dispigna.

► Snow will fall about 2 to 4 inches per hour with winds gusting up to 50 mph all of which make "whiteout conditions likely," forecasters said.

► 10:20 a.m. (high tide) — Expect 2 to 3 feet of flooding in coastal areas about the time of high tide.

► Late morning to early afternoon — Snow might be interrupted by some rain occasionally during this period, before becoming all snow again. 

► Sundown — The storm should be all but done by sundown at 7 p.m. though some flurries may continue through the night. Those aren't expected to accumulate though.

► Winds will continue through the night as temperatures drop to 20 degrees.

WEDNESDAY

► Temperatures will rise up to about 32 degrees though the winds will continue to blow up to 20 mph and the occasional snow shower could pepper the city in the afternoon.

THURSDAY AND FRIDAY

► Temperatures will finally begin to rise and the sun should come out, which will allow the snow to melt. Temperatures Thursday will rise up to 34 degrees in the day and then 38 come Friday.
