http://weather.uky.edu/about_lifted.htm WebThe Showalter index assumes latent instability of the 850-500 mb layer estimates the possibility for convective rainfall. To get the index lift a parcel dry adiabatically from 850 mb to its condensation level and moist adiabatically to 500mb (SI = T500 - Tp500). Showalter Index (SI= T500 - Tp500) SI >= 3 No convective rain 1 to 3 Showers likely
