Narrative:

Departed ZZZ airport in VFR conditions. Snow showers visible southwest through west to north and approaching. Clear in southerly direction of flight. After departing airport; rapidly moving snow showers from the west cut off intended route of flight; nearest airports became IFR in snow showers and flight became surrounded by deteriorating visibility. Trapped in an area of 2 miles visibility with lesser visibility all quadrants pilot elected to land on lightly traveled paved road. Better decision would have been to not depart in the first place considering rate and direction of deteriorating weather. Decision to land on a good paved road was far superior to continuing flight likely into IFR conditions with icing and possible controlled flight into terrain. Landing and [then departing within one hour] in good weather were uneventful with no hazard to ground traffic.
