Areas affected...North Central and Eastern Montana

Concerning...Severe Thunderstorm Watch 560...

Valid 260049Z - 260145Z

The severe weather threat for Severe Thunderstorm Watch 560
continues.

SUMMARY...The severe threat for WW 560 continues, as thunderstorms
in northern Montana have organized into a bowing MCS with outflow
winds capable of severe gusts.

DISCUSSION...Dry, well mixed boundary layer profiles have supported
the organization of thunderstorm outflow into linear bowing segments
capable of 60-70 MPH wind gusts across northern Montana. The most
intense corridor of thunderstorm winds is currently approaching
Glasgow, where the apex of the outflow bowing segment shows 55-60 kt
winds at 1200-1500 feet above ground. Given the well mixed nature of
the boundary layer, there is little preventing the transfer of this
momentum to the surface and could result in reports of wind damage.
Depending on the longevity of the linear segments, local watch
extension eastward could be needed.
