The Hudson and Mohawk River Valleys with surrounding mountains, appear to have a quantifiable effect on the occurrence of severe weather in upstate New York and western New England. Funneling of the low-level flow can create more favorable shear profiles for tornadoes and severe weather to occur in certain areas. The preferential occurrence of severe weather based on the 700 hPa flow direction also appears to be of an orographic nature.  The Adirondack, Green, Catskill, and Berkshire Mountains have a significant effect in initiating convection when the wind is in a favorable direction for upslope flow to occur.
