Thunderstorm Wind in Morrow County, Oregon

Pear tree had several limbs broken off.

Negatively tilted shortwave trough and the cold front associated with it aided in the development of late afternoon thunderstorms across northeast Oregon. Convection began just east of the Cascades and began to intensify into stronger to severe thunderstorms by the time it reached Morrow county. 3 Miles North of Heppner a pear tree had several limbs broken off and about 5 minutes of high winds. Pendleton had a downed tree, damage to a home, and power lines down, and a barn destroyed from the high winds. 7 miles north of Helix a mesonet measured a gust of 74 MPH. Over 2800 people were without power in the city of Weston due to the high winds from the severe thunderstorm.
