Record Weather Month (June)Finally Ends

"The Portland International Airport has officially closed the door on the all-time wettest June in Portland modern day history (1941-2010). The rose city received a rose-wilting 4.27" of precipitation during what many are now calling "Juneuary" 2010. About 95% of the month's total precipitation fell in the first 15 days of the month, which was enough to surpass almost 70 years worth of previous June records. It was also a cold month, with temperatures running more than 2 degrees below normal at months end. At one point about two-thirds of the way through the month, Portland was looking at the 2nd coldest June in history before finally warming up near the end of the month and thus pushing Portland out of the top 5 for coldest June's on record at the airport. Speaking of cold, the airport has reached 80 or warmer just four times this calendar year so far, with a maximum temperature of 83 degrees on June 23rd. By now we should have seen an average of about 8 days over 80 degrees in Portland.

Looking ahead, the 4th of July weekend looks dry and relatively mild, with temperatures in the 70's locally. But don't put away that SPF 100 just yet, as temperatures will likely soar to near record levels just after the 4th of July. Most of the daily records next week are in the 93-97 degree range in Portland. We may just be flirting with more records next week, just not the kind we have been used to as of late."
