Before revision:  In addition, the manuscript and associated website provide projections of deaths per day and total deaths throughout this period for the entire US, as well as for the District of Columbia. Our goal in this report is to provide a framework for evaluating the predictive validity of model forecasts for COVID19 outcomes as data become sequentially available, using the IHME prediction of daily deaths as an example.
After revision:  In addition, the manuscript and associated website provide projections of deaths per day and total deaths throughout this period for the entire US, as well as the predictive performance of the 95\% prediction intervals provided by the IHME models. We find that the initial IHME model underestimates the uncertainty surrounding the number of daily deaths as an example.
