HISTORIC AND DANGEROUS HEAT THROUGH THIS WEEK AND POSSIBLY THEWEEKEND.

A massive ridge of high pressure is currently parked over the West Coast and centered near the Washington/Canadian border. Beneath this ridge, a virtually cloudless sky is being observed across The Pacific Northwest along with unprecedented temperatures. This heat we are about to experience will likely be one of the most extreme and prolonged heat waves in recorded history. Northcentral Washington weather today will be sunny with possibly all-time record highs for places like Moses Lake, Ephrata, Quincy, Wenatchee and Omak with temperatures this afternoon between 110-115 degrees. This will threaten the health of all residents who are outdoors and especially those who are most vulnerable to heat.

Temperatures look to peak tomorrow with several all-time records likely broken for the second consecutive day with afternoon high temperatures between 114-118 degrees! The aforementioned ridge of high pressure will shift off to the east on Wednesday and our amplified pattern will slowly transition to a more zonal flow. This will help moderate temperatures slightly for the inland northwest with temperatures cooling a few degrees each day. That said, no major relief is in sight as lower elevations hover around the century mark through the holiday weekend.

Weather forecast for the Columbia Basin and Wenatchee Valley Wednesday through the Fourth of July on Sunday calling for sunny skies with sweltering heat, high temperatures on Wednesday between 110-115, slightly cooler readings by Thursday and into Sunday with afternoon high temperatures between 100-107 degrees.
