INGREDIENTS: Midday sunshine has allowed temperatures to climb into the mid 60s. Dew points are in the mid 50s. This combination is helping to give the atmosphere at least moderate levels of instability.
Wind shear values are high. This overlap of instability and wind shear will lead to the development of severe thunderstorms.
