Developing winter storm
Timeline
According to the FOX Forecast Center, a low-pressure system will develop over the Plains by Tuesday, but will initially lack the moisture needed to strengthen.

Forecasters said that as the future system moves off to the east, a strong, southerly jet stream will kick in, pulling in warm, moisture-rich air across the eastern half of the U.S.

That setup will create a well-defined warm front, separating the frigid air to the north from the record-breaking warmth swamping the South.

The issue is that the warm air will move into an area with a shallow layer of subfreezing air near the surface. That’s when problems could arise.
Big picture view
The first scenario includes a stronger low-pressure system developing over the Plains, remaining the dominant system.
With that, a stronger jet stream pulls in warm, moist air, leading to more freezing rain in parts of the Northeast.

With scenario two, a weaker low-pressure system would develop in the Plains, and a new coastal low would form along the East Coast and take over the dominant system.

A weaker low-level jet stream would mean less widespread freezing rain.

What they’re saying
“The next area of low-pressure comes by, that’s the one with that interesting wintry mix that wants to come through late Wednesday into Thursday,” FOX 5 NY’s Mike Woods said. “Looks a little more significant than what we had just pass by, but it’s something to watch, and it’s still a few days away.”
What we don’t know
Computer forecast models still disagree on the storm’s track and on whether it moves east, as expected at this time, or if a new coastal low develops along the East Coast.
