Phase Diagram (left): Shows the GFS analysis trajectory over the previous 10 days in black with diamonds corresponding to a position in the phase diagram at 00Z on the day labeled to the upper-right of its respective diamond. The red and blue symbols show the forecasted GFS and GEFS ensemble mean trajectories, respectively, within the phase diagram over the next 9 days with diamonds corresponding to a position in the phase diagram at 00Z on the day listed to the upper-right of its respective diamond. The green diamond shows the position within the phase diagram at 00Z on the day listed in the title.

Synoptic Maps (right): Depicts GFS deterministic 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. The 24-h forecasted accumulated precipitation is also used as 'verification' in Days -10 to 0.
