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.
