Hot back half of summer

Portland likely to see 90 degree heat this weekend with temps Sunday rising to near 100 degrees. As of Saturday morning, August 26th, PDX has hit 90 or better 15 days. With forecast models showing possible 90 degree heat through next Tuesday and again Labor Day weekend and another possible heat stretch around September 10th, the number of hot days may rise into the mid 20s, which would put the summer of 2017 on the list of hottest summers. Obviously, my projection of no more than 14 hot days (reaching 90 or better) is turning out to be way off! I simply did not see reason to expect what may be 12 sizzling days in the month of August. The most 90 degree days on record at PDX for August is 13 back in 1967. This month may challenge the record. Also, if Portland hits 90 or higher 25 times, this summer will be second to the hot year of 2015 when PDX hit 90, 29 times. Rod Hill

Before I begin, it is important to share with you my track record of accuracy for seasonal forecasting, dating back to 2000-2001.  Last winter my forecast was a success, largely because of my 67% confidence call for a below normal water year.  In fact, PDX recorded a water year ending September 30th of 30.03
