Phase Diagram (left): The green dot in all plots corresponds to the 0-h forecast on the date listed in the title. The blue dot is the ensemble mean position within the phase diagram for the forecast day listed in the title. The position of individual ensemble members within the phase diagram for the forecast day listed in the title are denoted by the red x's.

Synoptic Maps (right): Depicts GEFS ensemble mean forecasts of (1) 250-hPa wind speed, geo. heights, and standardized geo. height anomalies, (2) 500-hPa relative vorticity, geo. heights, and standardized geo. height anomalies (3) mean sea level pressure, 1000-500-hPa thickness, and 850-hPa standardized temperature anomalies, and (4) 24-h accumulated precipitation.
