It's about to get real hot in the northwestern US

July 30, 2017; 7:18 PM

Many records will be in jeopardy across the northwestern U.S. during the midweek as scorching heat builds in.

A ridge in the upper-air pattern will be focused along the West Coast this week, strengthening over the next couple of days.

This will result in a large and stagnant dome of hot air across the West, most notably across the Northwest U.S. and British Columbia.

The hottest days will be Tuesday to Thursday where temperatures are expected to average 10 to 20 F across the Northwest.

However, temperatures will be even higher across the Willamette Valley and all along the Interstate 5 corridor west of the Cascades. In this area, temperatures will be 20 to 30 F above-normal.

With anomalies that high, daily records will be in jeopardy for many major cities, from Vancouver, British Columbia, to Redding, California. The graphic below has a sampling of record-crushing heat expected on Wednesday.
