Winter Storm in St. Mary's, Maryland

A strong Nor'Easter moved northward along the Eastern Seaboard February 22nd into the 23rd. Temperatures were marginal to start outside of elevation, making the snowfall totals elevation dependent. This storm was unique as it had several local maxima across the state. The greatest amounts were in western Maryland across Garrett and western Allegany counties where 3 to upwards of 15 inches of snow fell. A secondary max associated with an inverted trough was observed from the Catoctins down to northern Montgomery county where 3 to 8 inches fell. Upwards of 12 inches were observed across the Catoctins. Another max of 3 to 6 inches was observed across Calvert and St. Mary's counties. The final max was Carroll to Cecil counties where 4 to 9 inches fell. Elsewhere across the DC and Baltimore metro, there was a relative minimum of 2 to 4 inches. Very little snow fell across eastern Allegany into far western Washington County.
