MARSHALL — Temperatures in southwest Minnesota are expected to climb again this weekend – and it’s possible that we could set some new records for heat, the National Weather Service said.

“We can expect this to be a pretty warm holiday weekend,” said Matthew Meyers, a meteorologist with the NWS office in Sioux Falls. High temperatures in Marshall are forecast to get into the upper nineties and low 100’s over Labor Day weekend. There’s a possibility the daytime high temperature could reach 101 degrees on Sunday, Meyers said.

Marshall could potentially break heat records for Sept. 2, 3, and 4, Meyers said. The city’s record high temperature for Sept. 2 is 96 degrees, which was set back in 1937. The record high for Sept. 3 was 95 degrees, in 1971. And the record high for Sept. 4 was 95 degrees, in 1938. The heat forecast for Marshall this weekend could also set records for warmest low temperatures for those dates, Meyers said.

“The good news is that the humidity is not as bad this time,” he said. The last heat wave Marshall had brought humidity and high heat indexes with it. This weekend, temperatures outside will feel pretty close to the actual temperature – although that’s still very hot, Meyers said.

As with previous heat waves, the NWS is encouraging area residents to take precautions like limiting the amount of time spent outdoors, finding shade and drinking plenty of water.

By the middle of next week, temperatures will gradually cool off a little, to levels that are more normal for this time of year, the NWS forecasts.
