A powerful winter storm system moving across the Great Lakes and Northeast is bringing snow and ice, frigid temperatures and possible whiteout conditions.

A new winter storm system could bring snow to the Northeast later this week, but forecasters say the exact outcome depends on how the weather patterns develop, according to the National Weather Service and AccuWeather.

A winter storm could track up the coast toward New Jersey, or move out to sea, in the second half of this week, forecasters say.

Forecasters are monitoring a late-week storm that could bring some wet winter weather to the Philadelphia area as temperatures plunge.

AccuWeather is predicting a chance of snow for York County on Thursday. The National Weather Service is calling for a chance of rain and snow, followed by a chance of snow at night. The high temperature on Thursday is expected to be 38 degrees. Check back for updates as this is a developing story.

At this point, 1–4 inches still looks reasonable across the Front Range, with a slushy 1–2 inches for many locations east of Denver across the plains. With marginal temperatures, significant melting is expected, and many areas will likely finish on the lower end of snowfall totals.
