Why So Rare?
Northeastern Position
Connecticut sits far from tornado corridors. Cold air masses generally dominate.
Ocean Effect
Long Island Sound and Atlantic Ocean influence weather patterns. Cool ocean reduces tornado potential.
Terrain
Connecticut's mixed terrain including hills and coastal areas doesn't favor supercell formation.
