Event narrative

Calculated heat risk values at the Pendleton Airport GHCN, the Pendleton Branch Experimental Station GHCN, and the Pilot Rock GHCN sites recorded several days between Aug. 8th through Aug. 10th of temperatures that met or exceeded excessive heat warning criteria.

Wider weather episode

High pressure from the four corners region extended northward into the Pacific Northwest, which resulted in well above normal temperatures across the region for several days. Many stations saw temperatures exceed critical heat risk thresholds, while stations in some mountain zones saw high temperatures consecutively meet or exceed 95 degrees under the strengthening high pressure aloft.
