As is tradition in Pittsburgh, Halloween week is marked with not just Kennywood Fright Nights and Trick-or-Treating, but also by the most important weather production of the year for the local news channels. Each year in the waning days of October, WTAE, WPXI, and KDKA all publish their Winter Weather Outlooks. They each forecast an average temperature and a season total snowfall based on long-term modeling and meteorological trends.<\/p>\n

Which forecast (if any) of the three should you take seriously? We have collected and analyzed the Winter Weather Outlooks\u00a0from each network for the past seven winters, comparing each forecast total snowfall with the official total archived by the National Weather Service. Over that period, the three networks have seen similar success, but the best has been WTAE with an error of 27.23 percent.\u00a0A table of each station\u2019s percent error by year, and a graph of their predictions against the actual season snowfall totals are included below.<\/p>\n

<\/p>\n

KDKA: 39.5 inches<\/strong><\/p>\n

As he typically does, KDKA Chief Meteorologist Jeff Verszyla traveled to State College to consult with AccuWeather’s long-range meteorologists for his Winter Weather Forecast. Based on several “macro” weather influences, including El Nino \/ La Nina, Verszyla predicts meager snowfall in November and December, a bit more in January, and a typical amount in February and March for a season of just under 40 inches of snow. (The average seasonal snowfall<\/a> for Pittsburgh is 41.4″)<\/p>\n
