Nick Vertz suspected calm weather wouldn’t soon return after last week’s high-speed wind event that recorded 101-mph winds in Glacier County. The Billings-based National Weather Service forecaster said Montanans should expect exceptionally strong gusts Tuesday night and Wednesday. “I joke that the weather’s just playing catch up with how mild of a fall and start to the winter we had,” Vertz told Montana Free Press on Tuesday.  Nearly the entire state is under an official high-wind warning, meaning the weather service expects wind speeds of 58 mph or greater. While the official warning status may vary by region, the weather service anticipates the strong winds will move west to east through late Wednesday evening. The National Weather Service hazard forecast covered the state in a high wind warning at 5:30 on Tuesday.

Vertz says high-speed winds aloft blowing downward is the result of warm weather. “You can think of it as pushing those strong winds aloft down to reach the surface,” Vertz said.  Though much of Montana experienced a similar strong-wind pattern last week, Vertz said this system  is a statewide event and that the weather service has “more confidence in those stronger winds to occur just all across the board.” With gusts coming out of the northwest, Vertz advised caution for drivers headed north or south, who would likely experience the “full brunt of those crosswinds.” Montana’s most recent experience with a major wind event on a similar scale occurred in January 2021, according to Vertz. Ongoing flooding in northwest Montana makes the area particularly vulnerable to high-wind hazards, like saturated soil around tree roots, according to Bryan Conlan, a weather service meteorologist based out of Missoula.  “Anywhere within western Montana at this point, with these strong to damaging winds, trees could blow over,” Conlan said. Gov. Greg Gianforte on Wednesday requested President Donald Trump issue a presidential disaster declaration in response to the flooding in the northwest part of the state.  As even more ocean moisture makes its way from the Pacific Northwest into Montana via “atmospheric rivers,” precipitation is likely to continue in western Montana. “One of the differences between this and the prior system is there will be a very strong cold front that’ll be coming along,” Conlan said.  A cold front on Wednesday will mix with moisture from the atmospheric river, producing a combination of rain and snow. Cold air also leads to winds aloft descending, resulting in strong wind across high elevations in western Montana. On Monday night, winds in Glacier National Park reached almost 100 mph. “This is going to be a fairly strong event,” Conlan said.
