The 0-h HRRR analyses showed 0-1 km vertical wind shear values in the pre-storm environment that were consistent with observed soundings at 1200 UTC 30 April. In closer proximity to the QLCS, however, the vertical wind shear increased to over 50 knots with the vector shear oriented almost perpendicular to the QLCS. The heterogeneity in the pre-storm environment highlights how the environment can become enhanced immediately ahead of active convection, where convection seemingly enhances its own inflow as also shown in previous works. Inspection of the HRRR forecasts suggests that there was some difficulty in accurately predicting the low-level mesovortices and attendant environment ahead of the QLCS. The 6- and 12-h forecasts verifying at 1200 UTC showed a more linear convective mode compared to the observed system with an absence of coherent long-lived mesovortices. The forecasts also had a pre-storm environment with less favorable conditions for the development of mesovortices, with lower 0-1 km vertical wind shear magnitudes and the vector shear oriented more parallel to the line (lower storm relative helicity). In the 1-h HRRR forecast, the QLCS has structure (complete with low-level mesovortices) and a pre-storm environment more consistent with observations. Emerging results from forecasts from the WoF system and analysis of the key model physical processes that are governing the accurate prediction of the pre-storm environment and convective mode will be discussed in detail.
