Record Cold May Day


A cold upper-level low combined with steady rain pretty much the entire day in most of SW Washington and NW Oregon has given us a record setting chilly May day:


  • 50 degrees (as of 5pm) just reaches the average low for this date
  • 50 degrees is the coldest daytime high for this date
  • 50 degrees is also the latest in the spring we’ve seen a 50 degree high temp
  • The coldest high temperature ever recorded in Portland in May was 49 degrees both in 1962 and 1964 (early in the month)

It only gets warmer after today (it can’t get colder right?), but it sure doesn’t get much drier.  Expect rain at times through next week.

By the way, MAYUARY is a combo of MAY/FEBRUARY (or January if you like).  After extensive input, I decided on that versus MAYVEMBER.

    That cold air is something else out there not quite like the start of summer. It looks to be indoor celebration time or subzero sleeping bag weekend in the hills with lots of water proof rain gear!

    Nice shower just moved thru the city fair now with a rain bow to boot! Mud must be up to the ankles by now.

    San Antonio had a lunch time shower that equated to 1.5″ inches in an hour and 15 min. My lawn got watered today down there and topped of the pool!
