Description:Techniques Development Laboratory has provided us a comparative verification of their two guidance packages over the period May 4 through June 30. The attached figures are from that study. Fig. 1 shows that over the Central Region, the PoP's from the NGM were generally (except for the 24-hr projection at 00Z) slightly better than the MOS. However, the mean absolute errors in temperature forecasts (Fig. 2) show that MOS performed better. A large part of this is due to a cold bias (numbers in parentheses on figure) in the NSM-based guidance.
