Tuesday morning's commute promises to be a rain-slicked slog along Hudson Valley roads following a mid-March storm that was expected to drop up to 6 inches in areas north of Interstate 287, forecasters said.
By 6 a.m., the snow that touched down in the Hudson Valley after the Monday evening rush will mostly yield to rain, creating some dangerous conditions for motorists, according to the National Weather Service.

"The roads will be wet instead of snow-covered but they will be slick," said National Weather Service meteorologist Dan Hofmann.
Hofmann said the transition from snow to rain will begin around 3 a.m. before turning completely to rain just ahead of the morning rush hour.
As predicted, the storm moved out of northeastern New Jersey and began falling in Rockland and Westchester counties shortly before 8 p.m. Monday, allowing evening commuters time to get home before snow started covering area roads.
"The snow's coming down at a pretty good clip," Hofmann said.
Accumulations were expected to come in at around 1-3 inches in Westchester and Rockland and as much as 3-4 inches on Westchester's northern border with Putnam County, Hofmann said.
The highest accumulations -- 3-6 inches -- are expected for Orange and Putnam counties, according to Hofmann. Points farther north like Binghamton could see as much as 10 inches of snow.
Temperatures near freezing in New York City left roads there covered with snow Monday night.
Although many in Westchester and Rockland will be forced to deal with a "slushy mess" Tuesday morning, commuters in the northern parts of the Hudson Valley will have to slog through the worst of it -- an icy, wintry mix, according to News12 meteorologist Brysen Van Eck.
The National Weather Service issued winter storm warnings for northern Westchester, Orange, Putnam and Rockland counties effective through 10 a.m. Tuesday and for Dutchess and Ulster counties effective through 8 p.m. Tuesday.
On Tuesday, rain is expected to taper off by noon, but frigid temperatures are forecast to continue as atmospheric conditions funnel Arctic air into the region, forecasters said.
"As we head into the weekend, it looks like it will be 5-8 degrees below normal for the next week or two," Van Eck said.
Tuesday temperatures are expected to climb to 45 degrees, with a low of 28 overnight.
The rest of the workweek will see temperatures in the low to mid-40s. Wednesday will be mostly sunny, with a chance of rain and snow and a low of 28 degrees overnight. Thursday could bring some more snow and rain, followed by sunshine Friday and a high of 41.
