The chill you felt Monday morning was the coldest air since January. (The photo above is my freshly-mowed, and now frosty, grass in Vancouver.)
Here are a few of the coldest unofficial low temperatures: Brush Prairie, (Clark County), 26 degrees, Hillsboro and Scappoose 27, Salem 28 and Portland 29 degrees. For Portland, today's chill was the coldest since January 22, when the low temperature was 24 degrees. The morning didn't quite reach the record low, which stands at 26 degrees in Portland.
So far, this has been a winter with little cold. February at PDX only had one freezing morning. The lowest temperature last month was 30 degrees, on Feb. 8. The airport did not see it's first freeze until December 29. Since that late Dec. day, only 18 more days have seen freezing temperatures, and nearly all were recorded during our colder-than-normal January.
Portland's annual average for freezing temperatures is 37 days. A typical March has three freezing starts. The average final Portland freeze is March 30. The record for the latest freeze was 32 degrees, back on May 2, 1964.
Stay warm and enjoy today's sunshine!
