The National Weather Service in Grand Forks declared a heat advisory for eastern North Dakota on Monday as temperatures reached into the 90-degree territory and humidity in some cities in the region was more than 70 percent, causing the heat index to hover around 100 degrees.
NWS meteorologist Brad Hopkins said heat advisories are declared on a day-by-day basis and there is a good chance they could continue throughout the week.
“That would be a judgement call by a later shift,” he said Monday afternoon. “If they find out tonight if it looks like it’s going to be the same thing tomorrow then they’ll reissue that.
“Right now the pattern that we’re in doesn’t look like we’re going to get much of (a break from the heat) for the moment. We might see high temperatures dip down to the mid to lower 80s by Friday, but there will still be plenty of moisture around so that will limit the low temperatures overnight.”
Hopkins also said there will be a continuing threat of heavy rains throughout the week, including severe thunderstorm that could pass through the area on the Fourth of July.
