"A light snowfall accumulation could result in snow-covered and icy roads for the Thursday morning commute," the National Weather Service said in a Hazardous Weather Outlook statement issued early Tuesday morning. "Monitor subsequent forecasts for updates on this event."
Thursday will be mostly cloudy with a high around 32 degrees.
Friday, Jan. 21 will be mostly sunny and cold, with a high in the low 20s, ahead of the potential for a more significant system Friday into Saturday, Jan. 22. (Click on the second image above.)
"There will be another fresh injection of Arctic air into the Northeast late this week, and as we have seen with this last storm, that can set the stage for a significant storm to unfold," AccuWeather Chief On-Air Meteorologist Bernie Rayno said.
Right now, there are two scenarios for the storm depending on the dip of the jet stream, Rayno said. If the jet stream dips farther inland, the chances increase for significant snowfall.
"In that case, the storm would tend to climb northward along the coast with the potential for snow or a wintry mix combination along the Interstate-95 corridor of the mid-Atlantic and New England," Rayno said.
