Wow! Looks like even without the east wind (it never made it out of the Gorge), our light north wind is mixing down the drier & hot air. It happened first earlier at Hillsboro, now PDX has made a 5 degree jump from 97-102 at 3pm. Best bet is that it maxes out near 104 or 105 at PDX. How exciting, the warmest temperature I’ve seen at PDX my career is almost here!
As you have all noticed, a thick layer of cloud cover is approaching, just in time for…tonight. The GFS & our RPM model showed this yesterday, and apparently they are right. It should move overhead during the nighttime hours, then head out of here early tomorrow afternoon. So cooler tomorrow, but what about a cloudy night AFTER a 104 degree day??? Our model shows mid-upper 70’s, which has never occurred at PDX. The record warm low is 74. Considering how thick the cloud cover is, this could be a record breaker. I’m glad the clouds didn’t show up midday and ruin our high temp….more later…Mark
