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 EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

A tornado touched down and destroyed two outbuildings. It also rolled a semi trailer.

The wider storm

Severe thunderstorms produced intense winds and large hail across Adams, Broomfield, Douglas, Jefferson, Morgan, Weld and Phillips counties. The hail ranged in size from one to two inches in diameter. Three short-lived brief tornadoes touched down in Phillips County. One caused moderate damage, when it destroyed two outbuildings and rolled over a semi-trailer. Very heavy rainfall in southeast Phillips County, caused flash flooding the forced closures of US 6 east of Holyoke and several other county roads southeast of town.
