FIGURE 5:
Panel (a) shows vertical velocity at 700 hPa predicted by the SM valid for 06 UTC 5 November 1994 (6 h forecast).
Panel (b) valid for 18 UTC 5 November 1994 (18 h forecast).

Final Remark

 It is felt that the Piedmont flood resulted from a dramatic and complex evolution on the synoptic as well as on the meso scale. From the present preliminary case study it is concluded that the SM produced a valuable forecast for this case, although no quantitative verification results have been presented.
