A stormy Monday evening and night likely will come on the heels of a hot, sticky day.
The National Weather Service in Grand Forks has issued a severe thunderstorm watch until 9 p.m. Monday. Northeast North Dakota and northwest Minnesota, including Cavalier, Grand Forks, Pembina, Griggs, Walsh, Nelson and Ramsey counties, could see dangerous thunderstorms late Monday afternoon and evening.
The NWS issued a report at 10:35 a.m. Monday, noting that thunderstorms are possible in northeastern North Dakota and northwest Minnesota . Any storms during the early afternoon are likely to remain weak, but they could produce lightning and some brief periods of heavy rainfall.
A brief shower with a few bolts of lightning came through Grand Forks late Monday morning.
However, late Monday afternoon and into Monday evening could bring dangerous storms.
Brad Hopkins, National Weather Service meteorologist in Grand Forks, reported that a combination of factors, including a frontal boundary in the west that will be moving east as the day progresses and a south wind drawing moisture up from the Gulf of Mexico are causing the potentially threatening weather.
The storms are expected to begin between 3 and 4 p.m., he said.
“We are starting to see stuff fire up around the Bismarck-Mandan area and up toward Minot,” Hopkins said.
The initial storms could bring a threat of hail greater than 2 inches, plus winds gusting up to 70 mph. Tornadoes are possible.
