Environment

Low pressure was working across the northern Great Lakes with a trailing cold front. A 40 knot low level (850 mb) jet was impinging on the forecast area, with mid level (500 mb) winds in excess of 80 knots.

While surface based CAPE (Convective Available Potential Energy) was on the lower side (500 to 750 J/KG), wind shear through much of the atmosphere was high in the 80 to 90 kt range with low level Storm Relative Helicity also favorable for rotation (200-300 m2/s2 ).
