Weather
While taxiing on Alpha Taxiway at a slower than usual rate for departure on Runway 33 and attempting to turn onto Alpha 1 to enter the runway; the aircraft continued sliding forward on Taxiway A. The right quartering tailwind combined with the icy taxiway caused the aircraft to depart the paved taxiway surface where the left main gear and nosewheel slipped off the paved surface onto the frozen ground. The right main gear remained on the paved surface. With the aircraft stopped we shut down the aircraft and arrangements were made with airport ground crews and maintenance personnel to have the airplane towed back onto the taxiway to the hangar where an inspection was made. No damage was found and the aircraft was deemed safe to fly. In addition no damage occurred to airport property.
