Overview

On the evening of February 27th 2024, a strong low pressure system developed over the Upper Midwest. The surface low tracked east along the Lower Great Lakes region into the overnight hours of the 28th. By 4am on the 28th, a warm front lifted northeast through the Upper Ohio Valley putting the Pittsburgh forecast area within the warm sector. The warm and moist unstable air advecting into the region set the stage for convection to organize. Winds aloft were impressive with 50 to 60 knot synoptic winds just off the surface according to the 12Z sounding. The environment in place along with the 40 to 50 knot effective bulk shear made conditions favorable for the extension and inclusion of some Ohio counties for a Tornado Watch. A severe storm developed and moved into the forecast area by 7am on the 28th. The storm produced an EF-2 Tornado and the storm itself contained the environment conditions to produce 70mph winds.
