An atmospheric stability Penman‐Brutsaert model for wet surface evaporation is developed for short time prediction of the diurnal latent heat flux. Monin‐Obukhov similarity theory is used in conjunction with a theoretical scalar roughness length for bluff rough surfaces in the formulation of the drying power of air. The robustness of the model is evaluated with lysimeter measurements of wet bare soil evaporation for a range of atmospheric conditions. Instances where radiation or local advection dominated were measured and modeled. Good agreement ( r 2 = 0.96) was obtained overall between the Penman‐Brutsaert derived evaporation rates and values measured by the lysimeters.
