No 80s before June has been unusual in recent years. Assuming the high temperature on May 31st holds at 79 degrees or cooler, this spring will match the cooler spring of 2011 in terms of no 80 degree temperatures prior to June 1st. The graphic below tells the story:
Extended weather models show a couple of possible 80-90 degree streaks in the weeks ahead, including June 8th through the 12th and June 26th through the 30th. The graphic shows Saturday June 11th - a possible near 90 degree sunny day with the red color indicating a strong ridge of high pressure that would lead to hot weather.
In between possible hot streaks, continued cool periods with a decent chance of above normal rainfall for the month of June. Normal June rainfall at PDX is 1.63", meaning 2.00" total would be a wet month.
May 2022 will end with 3.78", well above the norm of 2.51", but not close to the record of 5.55" set back in May of 1998.
