An area of low pressure tracked across southeastern Canada during the 12th, which brought an arctic front across the Mid Atlantic region late on the 12th. As this occurred, a strong area of high pressure located across central Canada built down into the Northeast, allowing very cold air to spill southward ultimately leading to what is known as cold air damming. This occurs east of the mountains down through the Mid Atlantic states. Meanwhile, a Pacific storm slammed onto the California coast during the 11th and as it moved eastward, a new area of low pressure developed across southeastern Colorado and the Texas Panhandle. This storm became impressive as it moved into the Ohio Valley during the 13th. However as additional energy moved into the eastern part of the country, a new area of low pressure developed near the North Carolina coast late on the 13th. This allowed mainly light snow to overspread the region from south to north during the early morning hours of the 13th. As the secondary area of low pressure became more organized to our south, moisture began to fill in across North Carolina and Virginia and this moved northward. The arctic front that slipped through the state on the 12th was positioned across the southern Delmarva and this began a northward jog during the night of the 13th and the morning of the 14th. The intensifying area of low pressure tracked very near southern Delaware and then slid close to the New Jersey Shore during the morning of the 14th. This system continued to intensify as it moved into New England during the afternoon and evening of the 14th. The track of the storm kept winds at the surface from the northeast, which pretty much locked in the cold air at the surface while some warmer air worked in above the surface for a period of time. The upper-level system then passed overhead during the evening of the 14th, with the entire system pretty much a memory by late in the evening of the 14th.
Snow began across Maryland���s Eastern Shore from south to north between 6 AM and 7 AM EST on the 13th. There was a lull in the precipitation during the evening hours of the 13th, however the precipitation became widespread overnight and during the early morning hours of the 14th. As some warmer air began to move in above the surface, the snow mixed with and changed to sleet and freezing rain between 12 PM and 4 PM EST. The mixed precipitation continued during the overnight hours of the 13th and the morning of the 14th in the northern part of the Eastern Shore. Plain rain fell farther to the south. In the north, somewhat milder air made its way in for a brief time during the morning of the 14th to allow some plain rain to mix in. After rising a couple of degrees above freezing around Midday on the 14th, the temperatures dropped back below freezing by late afternoon of the 14th with some snow showers before the precipitation came to an end around 8 PM on the 14th. The most significant sleet and ice accumulations occurred in Cecil County where up to a quarter of an inch of ice downed trees and power lines.
In Cecil County, Delmarva Power reported that about 12,000 customers in lost power starting the night of the 13th. Ice and snow contributed to a number of accidents as well. The state police barrack in North East handled about a dozen minor traffic accidents as of the afternoon of the 14th. An accident on Route 213 near Interstate 95 at about 10:30 AM on the 14th sent two people to Union Hospital after their vehicle lost control on the slippery roadway and struck a state plow truck, but neither was seriously injured. Cecil County schools were sent home early on the 13th and had the day off on the 14th because of the winter storm. North East town government canceled its mayor and commissioners meeting and rescheduled it for February 20th. County government offices also were closed on the 13th and 14th. In Kent County, on the afternoon of the 13th, a vehicle was traveling south on Route 213 in Chestertown when it slid on a patch of ice on the Chester River Bridge, crossed the center line and struck another vehicle. This closed the highway for an hour. Occupants of one of the vehicles were taken to Chester River Hospital Center for treatment. The bridge was not reopened until both lanes of Route 213 were heavily salted. At 9 AM on the 14th on Route 213 just north of the Route 298 intersection, a car struck a utility pole. Injuries were reported. Farther to the south on the Eastern Shore, precipitation started as snow during the morning of the 13th, then changed to a mixture of sleet and light freezing rain. Precipitation changed to plain rain by the evening of the 13th.
Some snow/sleet accumulations included 6.0 inches in the city of Conowingo (Cecil County) and 1.7 inches in Stevensville (Queen Anne���s County).
