March 11–15, 2018 Nor'easter

A winter storm, unofficially named ''Winter Storm Skylar'' by The Weather Channel, brought widespread blizzard conditions across the Northeastern United States, particularly New England in mid-March 2018. First impacting the Midwestern and Southern United States on March 11–12, causing travel impacts and producing high snowfall totals, the winter storm then moved into the Northeastern United States and became a nor'easter, producing blizzard conditions and heavy snowfall across portions of the interior Northeast on March 13–15. Heavy snow fell in Massachusetts, where most of the state received at least one foot of snow; the storm brought the heaviest March snow on record in Boston and Worcester. Over two feet of snow were reported in portions of Massachusetts, peaking at in Wilmington. Heavy snow also fell in Rhode Island, where the snowfall peaked at in Foster.

Meteorological history

On March 10, a disturbance was located across portions of the Great Plains, bringing snowfall. The next day, a low-pressure area in the Mid-Mississippi River valley brought additional snowfall across portions of the region, and then moved into the Appalachian Mountains. A separate, more dominant area of low-pressure also developed offshore of the Mid-Atlantic coastline, which then moved northeast on March 13. Rapid deepening then commenced overnight, with its central pressure dropping to at least , and a separate upper-level low trekked into areas near the New York/Pennsylvania border, causing heavy snowfall to occur across portions of the Northeastern United States, mostly focused along the New England portion of the coast.

As it strengthened, this also caused blizzard conditions across portions of the region, including areas in Massachusetts and Rhode Island, and causing high snow accumulations. A low-level convergence zone, combined with strong upper-level lift, continued snowfall across the same region in the evening hours of March 13, some heavy at times. The next day, snowfall was limited to areas downstream of lakes and in higher elevations as the upper-level low moved into New England, and by March 15, the moisture became limited as upper-level low pressure area moved into Canada. The system dissipated soon thereafter.
