The Mid-December 2018 Nor'easter was a fast moving nor'easter that struck the Eastern Seaboard between December 20-22. Forming as an Alberta clipper over Southwestern Canada, it initially produced light snowfall in Central United States as it tracked southeastwards. It eventually reached the Eastern Seaboard and began to grow rapidly into a nor'easter. Up to 15 inches of snow fell in the hardest hit areas before the system moved away from the coastline on the afternoon of December 22. It continued to produce lighter snowfall as it moved to the north of the British Isles on December 23. The Weather Channel dubbed the storm as Winter Storm Euclid becoming just Storm Euclid as dubbed by the Daily Mail.

Meteorological History Edit

On December 18, an Alberta clipper developed over Southern Alberta and dove southeastwards. With little moisture to supply it, it initialed snowfall totals in Central United States to be be between 1-4 inches. On December 20 at 0:00 UTC, the system spawned a surface low in the Gulf of Mexico. This low would become the dominant low of the system as it continued toward the Eastern Seaboard. The clipper system moved ashore of Florida on December 20 at 13:00 UTC, producing flurries in the Central and Northern parts of the state, turning to snow in Georgia. After moving offshore of Florida on December 20 at 15:00 UTC, the system began to rapidly intensify into a nor'easter achieving bombogenesis after receiving extra moisture from the Gulf Stream current. At the time the system's central pressure was measured at 994 millibars. This became 974 millibars at 15:00 UTC on December 21 while the system was located offshore of Delaware. Heavy snow subsided in the Northeast from December 21-22. On December 22, at 19:00 UTC, the bomb cyclone, nor'easter left the North American coast behind as it continued northeastward across the North Atlantic Ocean, accompanied by the polar jet stream. The storm reached it peak intensity of 943 millibars while located off the coast of Ireland at 22:00 UTC on December 23. This caused light snow to fall across the British Isles between December 23-24. On December 24 at 11:00 UTC, the storm system was absorbed by a windstorm forming over Northern Finland.
