Storms with dime-sized hail, flooding, high winds could hit Boise on Monday evening
A line of severe storms capable of producing lightning, wind gusts of up to 50 mph and at least dime-sized hail is quickly approaching Boise and could hit the city starting at around 5:30 p.m.
A group of storms formed northwest of the Treasure Valley in Oregon on Monday afternoon before developing into a single line and heading southeastward. The National Weather Service in Boise issued a special weather statement for the city, warning of torrential rain that could lead to localized flooding if it arrives.
The special weather statement likely will be upgraded to a severe thunderstorm watch or warning as storms approach, like at the Idaho-Oregon state line near Ontario and north of the Treasure Valley in Emmett.
“The sort of threats we’re looking at, we’ve got reports of dime-sized hail, but we’re expecting a little bit bigger than that in the stronger storms,” Weather Service meteorologist Jackson Macfarlane told the Idaho Statesman.
Any meaningful rainfall would be the first Boise has had since more than an inch of rain fell during storms that caused localized flooding in early June.
The Weather Service said the storms could last into the evening, but Macfarlane said the strongest storms would hit the area by 5:30 p.m. and move out by 6 p.m.
“Behind (the storms), we have some lingering light showers,” Macfarlane said. “While the storms are leaving half an hour after they arrive, we’re still going to have some lingering showers after they pass.”
