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.
Daily records will also likely be challenged or even broken on Tuesday and Thursday as well for this cities.
A few cities, including Portland, Oregon, may even tie or beat their all-time record high temperature on Wednesday. Think about that, Wednesday could be the hottest day on record for some places.
This will be a very hot three day stretch, and actually just a hot week overall.
The heatwave should be taken seriously. Below are some great tweets and graphics from the National Weather Service to help keep you and your family safe when dealing with the intense heat.

Temperatures will gradually start to decline at the end of the week and weekend as the ridge begins to break down.
