Global forecasts

Below are forecasts for the precipitation accumulation and maximum surface air temperature achieved during each of the next 3 days.  These are deterministic forecasts, meaning a single forecast is issued based on the best guess of the current state of the atmosphere (without any consideration for our uncertainty about that state).  All forecasts are direct output from the U.S. Global Forecasting System (GFS) model, and were initialized today at the time indicated below.
