Each year we use WRF in two high-resolution real-time seasonal applications. The first is the Spring Program for 3-km-grid cloud-permitting 48-hr convective forecasts over the central US in May and June, and the second is the Atlantic 5-day moving nested hurricane model with grid sizes down to 1.33 km on tropical cyclones and hurricanes from August till about October. These are both computationally demanding and require special resources on NCAR's IBMs, and the results are disseminated semi-operationally. The talk will summarize recent results and progress in these forecasts, and highlight some aspects related to microphysics parameterizations for each.
