12:00 PM (Tuesday) | *High impact storm to bring accumulating snow, ice, rain, and strong winds to the Mid-Atlantic/Northeast US from later tomorrow into early Thursday — Perspecta Weather

1 min read

In addition to the potential of accumulating snow, two other weather parameters will be of concern during this event. First, ice is likely to be a threat in parts of the Mid-Atlantic region as surface temperatures remain at or below freezing while milder air aloft causes sleet or freezing rain to fall. One such region where this could become a big issue during this mid-week storm is to the west and northwest of Washington, D.C. and it’ll be something to closely monitor. Second, winds can become quite a problem during the brunt of the storm with gusts possible of 40+ mph at inland locations and 60+ mph at coastal locations (e.g., NJ, Delmarva). This type of strong wind combined with accumulating ice and/or wet snow can certainly result in some power outages during the mid-week storm.

The latest snowfall estimates are as follows and they are still subject to change as a small shift in the storm track can make a big difference:

DC: 1-3 inches in the District, 3-6 inches in the N/W suburbs

Philly: 4-8 inches in Philly, 6-12 inches in the N/W suburbs

NYC: 6-12 inches throughout the metro region
