PORTLAND, Ore. -- Wednesday's rain set a record for the year along with some cold temps, breaking a dry and warm spell since the beginning of the month.
It was the fifth wettest May in history and the wettest day of the year so far. KGW Meteorologist Matt Zaffino said the average rainfall was on track for the month.
Totals overnight will range between 1/4 and 3/4 of an inch, Zaffino said.
The thermometer only briefly reached 50 degrees Wednesday, breaking the record for the coldest high temperature for this date. The previous coldest high for May 22 was 55 degrees, back in 1980.
The records for coldest high temperatures during the last week of May range from highs of 53 to 57 degrees, althogh the record book shows record-low highs in the 50s as late as June 29th.
Timberline Lodge reported eight inches of new snow and mountain passes from Government Camp to Willamette Pass to Santiam Pass all had snowfall on Wednesday.
Mount Hood campgrounds like Trillium Lake that were bare and brown earlier in the week were also dusted in snow, despite a scheduled opening for the Memorial Day Weekend.
Forecast outlooks continue to show below-normal rainfall for June, July and August. The summer temperature forecast is uncertain. At this time the temperature average this coming summer will most likely be near normal through the upcoming three months.
While Cascade snow is not common this time of the year, it is not unusual. In fact, Timberline Lodge can see snow all the way through July.
Rainfall from this week's cold upper-level low has pushed Portland over an inch for total rainfall this month. While PDX may finish the month with below-normal rainfall, May will not be among the top-five driest on record. In fact, we will likely finish the month with better than 50 percent of the normal 2.47 inches.
