A weather balloon released from Grand Junction measured a 134 knot (154 mph wind) wind at nearly 30,000 feet, establishing a new record for jet stream level winds at this height in the month of November over western Colorado.

Wind records for the upper atmosphere have been kept since Jan. 1, 1948.

The powerful jet stream was associated with a trough of low pressure over the northwestern United States and was responsible for bringing wind and snow to Colorado’s high country.
