Pacific Northwest Heatwave Alert: Triple-Digit Temperatures Expected

The Pacific Northwest is in for a dramatic shift in weather as a strong ridge of high pressure builds over the region, promising a record-breaking heatwave this weekend. After a cool and rainy start to the week, residents can expect a rapid temperature spikewith some areas potentially reaching triple-digit temperatures.

This weather pattern is expected to bring summer-like conditions to the region, with temperatures in the Portland/Vancouver metro area likely to climb into the mid-90s by Sunday. The current forecast suggests that this could be the strongest ridge of high pressure of the spring season, surpassing the brief 90-degree temperatures experienced in early May.

Record-Breaking Temperatures Expected

The Portland airport set a record high temperature of 89 degrees back in 1988, a record that is likely to be broken this weekend. Forecasts indicate that temperatures will soar into the 90s by Saturday and continue to rise on Sunday and Monday. Monday’s record high of 95 degreesset in 1966, may also be in jeopardy of being tied or broken.

A consensus of weather models suggests that temperatures will reach at least the mid-90s across the Portland/Vancouver metro area by Sunday. Some outlying models even suggest the possibility of triple-digit heat. Typically, Portland considers a heat wave to be three days or more of temperatures at or above 90 degreesa mark that is likely to be met with the upcoming pattern.
