Heavy Snow in Ridges of E Monongalia and Nw Preston, West Virginia

Low pressure, strengthened by a deepening upper trough, lifted northward from the lower Mississippi through the Tennessee Valley with cyclogenesis occurring along the Carolinas. As a result, and with reinforcing cold air in northwesterly flow over the upper Ohio Valley, snow spread across the region late Friday morning. Snow became heavy at times in enhanced mesoscale banding, over areas south and east of Pittsburgh, with a very tight gradient in snow amounts across Allegheny county. The highest snow amounts were reported occurred at Redhouse and Oakland in Garrett county Maryland with 38 and 36 inches of snow respectively. This surpasses the previous 2-day total for Oakland dating back to 1983. Additional high snow totals include Tunnelton and Hazelton, in Preston county, West Virginia with 34 inches, and 24 inches in Davis, Tucker county West Virginia. Over two feet of snow was reported further north and west over Marion and Monongalia counties in West Virginia, and Westmoreland and Fayette counties in Pennsylvania. For reference, the range over Allegheny county spanned from 2 to 9 inches from the northwest to the southeast. A State of Emergency was declared in Pennsylvania and Maryland, with Presidential declarations added later.
