The back half of May has seen a handful of 70 and 80 degree days in a month which has typically heralded the end of the rainy season leading into the drier summer months. Through Tuesday of this week, Sea-Tac Airport (where records are measured for the Seattle area) clocked in at an average of 61 degrees for the month combined between highs and lows.

#Seattle average temperature (highs, lows combined) will likely come in at 60.9°F in May. That would be second-warmest May since @FlySEA records started in 1945. It looks like it would be second-warmest too, bringing in previous Seattle weather records. #wawx pic.twitter.com/qsp31hadUp

This will lead straight into more summer-like weather to kick off June. A warmup starts Thursday to begin June with plenty of highs in the 70s by the weekend, and we could see some 80s Sunday through early next week.
