Fall officially arrived Friday, September 22nd but it seemed like we skipped over fall and right into winter western portions of the United States. Higher elevations received several inches of snow and new record lows were set over the weekend. You won’t need your winter coats anymore though as we head into the later portions of this week. Temperatures are warming back on up! A ridge of high pressure is going to be building over the west coast allowing the heat to return. That high will be pumping in warmth from the south and temperatures will be climbing in the 80s and 90s across the west.
This is well above average for this time of year. The last time places like Seattle, WA or Portland, OR made into the 80s for the last week in September was about 10 years ago. So to put it simply, the northwest definitely isn’t used to summertime-like temperatures in late September.
While this won’t be record breaking heat, temperatures will still be well above average. Check out these comparisons for the potential highs Thursday vs. the average highs. Seattle could make it about 15 degrees warmer than usual.
