If it seems our seemingly days-on end of 80s this past month is a bit unusual, you would be right.
This July goes down as the 2nd hottest on record at Sea-Tac Airport if you count by average temperature (high+low divided by 2) or 4th hottest if you just want to count high temperatures.
The average temperature was 69.2 degrees, second behind July 2009's 69.5 degrees. The average high temperature was 80.4, 4th warmest on record (81.4 in 1958, 81.0 in 2009 and 80.9 in 1985.)
It makes sense, considering Seattle rattled off a 12-day streak of high temperatures at 80 degrees or warmer -- second longest streak on record -- and was going to finish the month on a new 5-day streak.
Overall, the month had 19 days at 80 degrees or warmer, second-most behind the 21 in 1985 (and more than uber heat wave 2009! Then again, some of that heat wave stretched into early August.) Seattle averages 25 days over 80 per year. Thursday makes 24 for 2014.
We've had a big ridge of high pressure parked over much of the Western United States for the month, giving us steady heat while on the flip side, bringing a relative summer "chill" to the Midwest and East Coast as a trough of low pressure has been stuck over there. As Seattle reached one of its hottest July's, Indianapolis just finished up their coldest July on record. (But they were still warmer than Seattle, with an average temp at 70.1)
The medium range forecasts say August will begin much of the same with sunshine and highs in the low-mid 80s. And as for the rest of summer? The long range forecast models say expect to remain warm and dry.
