The temperature dropped 5°F, so it is now 71°F - 5°F = <<71-5=66>>66°F.
Then the temperature rose 8°F, so it is now 66°F + 8°F = <<66+8=74>>74°F.
Therefore, the temperature needs to fall by 74°F - 71°F = <<74-71=3>>3°F to return to the initial temperature. Answer: \boxed{3}.
On a given morning, the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F.
