Hail in Ascension Parish, Louisiana

Quarter sized hail reported between Prairieville and Port Vincent.

By mid-afternoon on February 11th, an upper level trough over the Texas Panhandle was moving eastward. A cold front associated with this feature was moving east through Texas, eventually across southern Louisiana and Mississippi. As a warm front lifted north ahead of the approaching cold front, low level temps and moisture jumped up which substantially increased buoyancy. Afternoon and evening upper air soundings at KLIX showed ample instability and wind shear that was more than sufficient for convective development. Modest moisture in the atmospheric column was enough to support scattered to numerous thunderstorms but not so high that it would just be a heavy rain event. Lift from the cold front as it moved through the local area combined with the instability and shear resulted in multiple severe thunderstorms. The strongest storm produced hail up to 2 inches in diameter.
