The same system that brought such devastating weather to the Ohio Valley was also responsible for putting a chill in the mid-Atlantic. When we forecast for Lynchburg almost two weeks ago, nobody anticipated the plummeting temperatures on the evening of December 12th. We all more or less suspected a non-standard day, but not THIS non-standard. It was 27 degrees by the time the 12th turned to the 13th, and forecasts busted across the board. The fast arriving front also prevented record highs on Saturday, which was against the grain for some outlets as well. Forecast.io ended up collecting the wind, mitigating their losses with a cooler forecast.
