Eddie Howe's men are now fourth in the Premier League after their second win in a week - a superb 2-1 victory at Tottenham Hotspur on Sunday.
The Lilywhites had won all five of their previous home games but Callum Wilson and Miguel Almirón ended that run to close the gap between them and the North London club, who are third, to two points.
Harry Kane halved the deficit in the second half, but the league's meanest defence never really looked like conceding again - although Nick Pope made two big saves in the first period.
It meant that the Magpies' travelling fans were singing in the rain at the final whistle, and club photographer Serena Taylor brought nufc.co.uk this gallery from the capital.
