The National Weather Service says the temperature hit 88 degrees on Tuesday for a second consecutive day in Caribou.

All told, there have been four consecutive daily high temperature records set in the city. Meteorologist Victor Nouhan (NOO'-han) says it's the longest streak of 80-degree days recorded this late in the season in Caribou.

Forecasters say there's going to be a gradual cooldown and temperatures will turn more autumn-like by Thursday.
