This session will focus on the dynamics and predictability of high impact weather until a few days ahead, including nowcasting. The session will accept papers on a wide range of topics that include the following:

i) Theoretical, modelling and observational studies of the dynamical sequence of events that result in well, but also poorly predicted high impact weather events,

ii) Investigations into the dynamical and physical factors that limit the skill of current predictions,

iii) Nowcasting studies and applications.

Case studies coming from the operational experience of forecasters are welcome. They may address also the performance and verification of nowcasting systems and NWP models (especially on situations affected by high impact weather), as well as the tools implemented for a specific use of NWP forecasts (hydrology, risk of floods, of icing,etc...).
