Grab your umbrellas: Fall storms hit Boise region, with more on the way
The first thunderstorm of the autumn season hit the Boise area Wednesday, and weather experts say more is on the way.
Parts of the Treasure Valley — most notably Boise, Eagle, Meridian and Melba — saw scattered storms Wednesday morning. Some areas may even see hail, according to the National Weather Service.
“Right now, we’re seeing some spotty rain, locally heavy rain, even a few lightning strikes and some gusty winds,” Jaret Rogers, Boise-based National Weather Service meteorologist, told the Idaho Statesman shortly after 9 a.m.
Rogers predicted the morning’s storm activity would persist through about 10 a.m. or 11 a.m.
But that won’t be the last that the area will see of thunder and rain. Following a dry spell through the middle of the day, the National Weather Service is expecting a second round of storms to hit sometime after 3 p.m.
That second round will be coming from the Owyhee Mountains, Rogers said.
“We’re anticipating that we’ll see the development of more thunderstorms, especially to the south of the Boise area, and then those will move northward later today,” Rogers said. “We’re also looking at storms over the mountains north of the Treasure Valley and east of the Treasure Valley.”
Rogers said the level of rainfall will vary widely across the region. Not everywhere will get significant precipitation.
“But if one of those storms hits you and stays over your location for a little while, it could put down up to a half-inch of rain or so,” Rogers said.
Thursday and Friday could see additional isolated showers and thunderstorms, according to the National Weather Service.
The wet weather was brought by a large low-pressure system over northern California that came in off the Pacific Ocean, which “is pretty typical when you start to move into fall,” Rogers said.
That system is also bringing cooler temperatures. Rogers said he expects highs to stay in the 70s this week, though they could hit the low 80s this weekend.
“Generally, it’s going to be much more seasonable for temperatures, which will be nice,” Rogers said. “It will feel more like fall around here.”
