NAS Weather Index (WITI) vs.Combined WITI-FAand Delta (“forecast goodness”) 30-day period ending 11/12/2008 NWX = 100 is a “normally-impacted ” day Positive delta = Over-forecast of traffic impact Negative delta = Under-forecast of traffic impact Delta > +/-50 may indicate a forecast “issue” November 12, 2008 21
OEP Airports Analysis Under-forecast at BOS (actual ceilings, 600-700 Ft, lower than forecast ceilings, 1300-1500 Ft) – however, no impact on operations due to low traffic demand on a Sunday
