CARIBOU, Maine — Last month has gone down in the record books as the wettest July ever in northern Maine.

The National Weather Service says Caribou got 7.93 inches of rain last month, breaking the old record of 6.83 inches set in 1957. June was also a record-setter, with 9.03 inches.

Meteorologists say there was a stark difference in July’s rainfall amounts from northern Maine and the rest of the state because of an unusually strong upper level jet stream separating hot air to the south from cooler air to the north that resulted in heavy rains over northern areas.

By comparison, Bangor had 2.9 inches of rain for the month, which is about 35 percent below normal.
