Forecast Tools (Prototype):



1/3/6/24-hr Changes

Change in weather parameters over the last 1/3/6/24 hours. The data used here is either from the Real-Time Mesoscale Analysis (RTMA) or the Rapid Refresh (RAP). The RTMA is shown at its native resolution of 2.5km and is used for surface variables. The RAP is shown at 32km (native resolution 13km) and is primarily used for non-surface (i.e., upper level) variables. For more information please see the RTMA or the RAP website.



GEFS Probabilities

This forecast product shows probabilistic information for the lower 48 states from the GEFS. This updates four times daily. Probabilities of exceeding or remaining less than such variables as precipitation, temperature, or sea-level pressure at various thresholds are displayed.
