feasible (or expected) for this study, a similar study with a forecasting system might provide some additional useful insights into the application of storyline methods since the data that are presented to the model in the counterfactual case would then have to satisfy the thermal and dynamical balance constraints that would be imposed by the assimilation system. While this might make the counterfactual more difficult to implement, the use of an ensemble analysis and forecasting system would, in particular, provide some interesting possibilities for the quantification of uncertainties. Such an approach would also provide a “seamless” connection to probabilistic event attribution approaches (see next comment) that could draw on probabilistic weather forecasting techniques. Some discussion along these lines might be merited.
