An inflatable air mattress for preventing snow accumulation is provided. The mattress comprises an inflatable portion comprising a textile material, and an outside air intake. A fan draws outside air into the inflatable portion through the air intake, and circulates the air when inflated. An air divider alternates between an inflating position and a circulating position that determines which air the fan blows. An air heater heats the air that passes through the fan. A controller activates the fan and air heater based on a signal from a snow sensor controls the divider based on a signal from a pressure sensor and controls the heater based on a signal from a heat sensor.
