Last week's stretch of warmth would not be considered abnormal or extreme by summer standards, but was highly unusual given the current time on the calendar. From Sept. 24-27, high temperatures were often up to 20 degrees Fahrenheit above average for the time of year, and even set records in some cases. This heat was most notable in the Northwest, where high temperatures typically hover in the upper 60s to low 70s in late September along the busy Interstate-5 corridor. In Seattle, temperatures peaked in the lower 80s from Sept. 25-26, setting the daily record on the latter day. Meanwhile, no records were officially set in Portland, Oregon, but the mercury surged to 90 degrees on Monday, Sept. 26, a very rare feat for late September.
After abnormal warmth overspread much of the West Coast early last week, more typical cool and wet conditions closed out the month of September in the Northwest. However, with the up-and-down temperatures often felt in fall, AccuWeather meteorologists warn that near-record high temperatures are likely over the next few days, with conditions feeling more like August than October for many in the Pacific Northwest.
“The calendar recently flipped to October, but it certainly will not feel like fall across the Northwest,” AccuWeather Meteorologist Joe Curtis said.
