The wider storm

A fast-moving shortwave upper level trough followed by a shortwave ridge tracking near the International Border produced a strong surface pressure gradient on the 7th and accompanying strong winds across North-Central MT. Heading into the 8th, the upper level ridge broke down. This day brought a longer duration of strong sustained winds and widespread strong wind gusts over North-Central MT.
