IRON MOUNTAIN - The high temperature recorded on Tuesday was 94 degrees, but that wasn't the hottest day on record for that date in history, according to the National Weather Service in Marquette.

The Ford Airport in Kingsford and the Iron Mountain-Kingsford Wastewater Treatment Plant in Breitung Township each reported a high of 94 degrees on Tuesday.
The high temperature today is expected to hit 91 or 92 degrees.
The last five days have been above normal for the U.P., weather officials confirmed. Thursday's high temperature is expected to be 85 degrees.
A hazardous weather outlook has been issued for western and central Upper Michigan.
Scattered thunderstorms will develop this afternoon and become most numerous inland from Lake Superior and continue tonight.
Damaging winds, large hail and heavy rain is expected with the storms.
A cold front with heavy rain storms will move in Thursday night.
From Thursday into Friday afternoon and evening, the torrential rain could lead to flash flooding, the Weather Service said.
Friday's high temperature is expected to be 83 degrees, Saturday's high is forecasted at 72 degrees and Sunday's high temperature could be 73 degrees.
The low temperature on Saturday night is forecasted at 57 degrees and 47 degrees on Sunday night.
The Iron Mountain-Kingsford Wastewater Treatment Plant in Breitung Township recorded a high temperature of 100 degrees on July 16, Weather Service officials said, but neither the Weather Service nor officials at the Wastewater Treatment Plant were able to determine the year the record was set.
Elsewhere, Wisconsin emergency management and health officials are urging residents to take precautions in the face of hot, humid weather in the next few days.
The Department of Health Services says last year 27 people died in Wisconsin as a result of heat-related issues. This year, one heat-related death in Wisconsin has been reported and that was last month in Juneau County.
State officials urge neighbors to check on elderly residents, especially those without air conditioning. People without air conditioning are urged to stay with friends or family members who have it or seek out like senior centers, malls and libraries.
The heat and humidity can be hard on anyone who works or spends a great amount of time outdoors, but it can also be tough on milk-producing cows.
Dr. Marcia Endres, from the University of Minnesota-Extension, says the higher temperatures can reduce a cow's milk production by 10 to 15 percent - or up to two gallons a day.
Endres said it takes a few days for a milk-producing cow to show symptoms of heat stress, but the effects can last much longer.
The University of Minnesota is researching ways to warn dairy farmers that a cow is beginning to experience heat stress. One experiment implants a thermometer in a cow's stomach to send an email or text alert to the farmer before heat stress has a chance to escalate.
In Detroit, the National Weather Service has issued heat advisories for much of Lower Michigan as high temperatures from the eastern U.S. make their way west.
Heat indices in southeastern, western and parts of northern Lower Michigan are expected to approach, and in some cases exceed, 100 degrees on Tuesday and into Wednesday.
Those indices aren't the actual temperatures, but represent how hot it feels outside, taking humidity into account.
Some communities are providing cooling centers such as libraries to allow residents to beat the heat during the dangerous afternoon hours.
The Education Achievement Authority has canceled classes at its 15 schools in Detroit through the remainder of the week. And Grand Rapids Community College said Tuesday that it closed its Ford Fieldhouse through Wednesday because of the heat.
