HOUGHTON - July temperatures in the Keweenaw have fluctuated between very warm and rather cool, but overall lower temperatures have prevailed, according to Keith Cooley.
Cooley, who is a meteorologist with the National Weather Service office in Negaunee Township, said conditions for July have been similar for the entire U.P.
"We've been about 3 degrees below normal," he said.

A pickup moves slowly in downtown Houghton during an extremely heavy downpour Tuesday. According to the National Weather Service Negaunee Township office, July precipitation in the western Upper Peninsula was about 3 inches above normal, but July temperatures were about 3 degrees below normal.
Cooley said the normal high temperatures for the U.P. are about 72 degrees, and the normal lows are about 49 degrees.
A weather trough system over the Midwest has allowed relatively cold air to funnel down from Canada, Cooley said, causing the cooler temperatures.
There have been some highs in the 80s and 90s this month, but Cooley said that's not unusual, either.
"It's not uncommon in July and August for it to get up like that," he said.
For June, Cooley said temperatures averaged 61.1 degrees for the entire U.P. The normal temperature for June is about 60.6 degrees. Worldwide, June was one of the warmest recorded.
Precipitation for July in the western U.P. has been about 3 inches above the normal amount of about 18.5 inches, Cooley said.
At the NWS Negaunee Township office, so far in July 5.63 inches of rain have been recorded.
The normal is 2.84 inches.
Cooley said another trough pattern is expected from today through Monday.
"It's going to be cooler," he said.
Temperatures for that period will be in the mid to upper 60s, Cooley said.
"That would be 10 to 15 degrees below normal," he said.
The weather pattern will also bring some precipitation, also, Cooley said. Through Monday, there are chances of rain.
"There could be a couple thunderstorms mixed in there," he said.
