p "from the top to the shallow . . . inversion . . ., but . . . more stable and moist through the middle levels of the atmosphere" (Szoke & Brady, p. 1843). As the time of the collision between the stationary boundary and the mesoscale outflow approached, however, surface conditions became much drier. The drier near-surface conditions resulted from a south-to-southwest low-level flow having a downslope component that was not present in the wind profiles in other Northeastern Colorado sites. At the site of the collision, the Lifting Condensation Level (LCL) "was rather high, about 3.7 km MSL, or 580 mb. Because of the projected deep afternoon boundary layer, even using the moisture through the 700 md level may have overestimated the
