Preparations are underway from Houston to Atlanta as a rare winter storm sets its sights on the southern U.S., where it's expected to bring a messy mix of heavy snow, sleet and freezing rain that could have a major impact on travel and daily life.

Dangerous cold temperatures are in the forecast for Delaware, but meteorologists are watching a system that could produce a severe storm.

A storm will bring rain and snow to Delaware on Jan. 19. The more north in Delaware you are, the more likely you are to have a few inches of snow.

The storm, which will hit the Delmarva Peninsula and Pennsylvania and New Jersey on Friday night into Saturday, is expected to bring 1-3 inches of snow to Sussex County, the National Weather Service said Friday morning. Kent and New Castle counties may see 1-2 inches and less than 1 inch, respectively.

The New Castle County Airport received 0.5" of a very powdery snow Thursday evening, as a low pressure system passed through the area.

Wind gusts could reach 50 mph today in parts of Delaware before a winter storm brings weekend snowfall. See the First State weather forecast.

A winter storm is on the approach ahead of Sunday's Eagles matchup, with snow beginning around lunchtime and lasting throughout the playoff game.

Between 3-5 inches of snow is expected over in Philadelphia, along with lower Montgomery County and upper Gloucester, Camden and Burlington counties in South Jersey. The highest snow totals are expected across the southern half of Delaware and through Cape May, Atlantic and Cumberland counties in South Jersey.

Another snowstorm is projected to hit Delaware this weekend, just in time for the Eagles-Rams playoff game. But how much? See the latest forecast.

Light snowfall clipped Delaware and went offshore, leaving a brief warm-up and another week of bitter cold for the First State.

The National Weather Service issued an updated weather alert at 9:12 p.m. on Thursday for light snow until Friday at 1 a.m. for Western Chester, Eastern Chester, Western Montgomery, Eastern Montgomery and Lower Bucks as well as Berks,

It'll be very cold on Sunday in South Philadelphia when the Eagles host the Rams, and snow may accumulate during and after the game.
