91 in Portland Monday

August 13, 2018

11pm Monday

Even with the thick fire smoke overhead we managed to make it over 90 in Portland once again as we head into a 3 day period of hot weather.  That makes today our 27th day reaching 90 this year.  It appears we’re going to break a record this year…likely early next week.

90 Degree Days Summer Heat

Assuming the smoke is at least as thick tomorrow, we should stay in the low-mid 90s once again.  IF we had typical clear blue sky I would forecast 100 degrees for Tuesday.  We have light easterly flow through the Gorge and over the Cascades plus 850mb temps should peak out around +22 by afternoon.  Luckily that smoke coming from fires in British Columbia, Northern Washington, & SW Oregon will keep temps lower.

There’s one other bit of good news, our average temperature begins to fall off tomorrow as we move into the final weeks of summer.

Heat of Summer Hot Temps

EVENTUALLY, it will turn cooler after this blazing hot summer of 2018!
