A complex area of low pressure over the middle Atlantic, which involved several individual centers, slowly consolidated off the Virginia Capes Tuesday morning, March 20th into Wednesday March 21st along a frontal boundary. This primary low, the fourth nor'easter this month, gradually moved northeast Wednesday night, to a position southeast of the 40 North/70 West ���Benchmark��� coordinates on Thursday morning.
Rain developed across the eastern shore of Maryland on Tuesday morning, March 20th. As this precipitation moved northward into a colder air mass, snow and sleet developed across the northern portion of the eastern shore of Maryland during the Tuesday afternoon hours.
During Tuesday evening, a mixed bag of precipitation developed, with freezing rain, sleet, and snow, expect rain closer to the coast.
Freezing rain lead to ice accretion up to 0.20��� across the northern portion of the eastern shore of Maryland, causing downed trees and limbs, which impacted power lines, and lead to power outages.
The change over to snow progressed southeast across eastern shore of Maryland by late morning on Wednesday March 21st.
Moderate to heavy snowfall developed, and gradually overspread eastern shore of Maryland from Wednesday morning into the evening. Snowfall rates, particularly outside of the southern portion of the eastern shore of Maryland, were around one inch per hour at times. The snow gradually ended from west to east around midnight.
Snowfall amounts over the eastern shore of Maryland generally ranged from 8 to 12 inches over Cecil County, 6 to 9 inches over the remainder of the area, with the exception of Queen Anne���s and Talbot Counties, where amounts tapered southward down into the 2 to 4 inch range.
The weight of the heavy, wet snow brought down trees, limbs, and power lines across the northern portion of the eastern shore of Maryland, which led to power outages.
