Aircraft
During VFR pipeline patrol with a weather briefing from 1.8 hours in the future; we had an alternator failure (the second in two days). I elected to fly 20 minutes more to 'finish the mission' for one of our customers.Saving the remaining battery power; we only turned radios ON when near airports. Upon approaching my destination; I tuned AWOS and heard 'Visibility 8 miles; Ceiling 800 ft'. We continued; following the Interstate (just under the ceiling) until the airport was in sight; and made a no-flap landing.
C182 pilot reported an alternator failure and landed the aircraft in IMC weather.
