Abstract
The use of WRF simulations to study the sources of error in warm-season precipitation forecasts is discussed. A 10 day simulation for a period (10-29 July 1998) is analyzed, during which heavy precipitation events near the lee of Rocky mountains is observed. The simulations will lead to improve operational forecasts of warm season precipitation and help elucidate dynamical mechanisms responsible for rainfall coherence. It is observed from the simulation that the relatively slow phase speeds of the coherent deep convection during the latter portion of the period are correlated with the phase speeds of simulated disturbances in the midtropospheric meridional flow.
