NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado touched down 5.5 miles southwest of Glentana at 5:47 PM MDT, moving to the northeast and directly impacting the town of Glentana at 5:53 MDT. Several blue spruce trees were uprooted, several grain hopper bins and some garages and farm machine buildings were destroyed. The roof from a house was blown off. The Glentana Hall metal roof peeled off on the south side. Multiple farm machinery equipment were damaged. Some straight line wind damage including one dozen power poles snapped, was observed 0.5 miles south of the path of the tornado on South Glentana Road. The tornado continued toward the northeast and lifted at 5:56 PM MDT, 2.4 miles northeast of Glentana.

The wider storm

An upper level low pressure system moved along the Canadian border throughout the day. This feature dragged a cold front through Montana that set off multiple thunderstorms. Some of the storms became severe and one generated a tornado that impacted the town of Glentana.

Began near Glentana (48.8500, -106.2500).
