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.
âThat would be a judgement call by a later shift,â he said Monday afternoon. âIf they find out tonight if it looks like itâs going to be the same thing tomorrow then theyâll reissue that.
âRight now the pattern that weâre in doesnât look like weâre 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.â
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.
