We describe simple analytical formulae constructed to approximate the temporal behavior of the temperature, density, and radius of various presupernova shells immediately after the arrival of the supernova shock wave. The formulae are derived from detailed hydrodynamical simulation of the supernova envelope expulsion. When used within traditional nuclear kinetic codes, the formulae are expected to be a useful tool for adjusting the resulting nuclear yields to current supernova models.

Key words: stars: supernovae: general -- shock waves -- nuclear reactions, nucleosynthesis, abundances
