The mercury will be rising in the Emerald City this week, and it could be soaring to never-before-seen levels.
Seattle, Washington will be sweltering all week long as temperatures rise well into the 90s and potentially into the extremely rare 100°-plus threshold. Excessive Heat Watches have been posted for Seattle from Tuesday through Friday in anticipation of this potentially record-setting spell of hot weather.
This computer model forecast, the Global Forecast System (GFS), shows temperatures matching Seattle’s all-time warmest on record, set back on July 29th, 2009. If Seattle hits 100° Tuesday or later, it would mark only the third time the city’s hit 100° or more in recorded history, and it would make it Seattle’s first ever 100° reading in the month of August on record.
Anchored by the temperate waters of the adjacent Pacific Ocean, Seattle is typically mild during the summer months, with average highs Seattle only topping out in the mid 70s in July and August, the city’s warmest months of the year on average.
It’s all thanks to a huge and persistent ‘ridge’ pattern across the western United States, which will allow heat to build for several days, building to exceptional levels by the end of the week. Strong offshore winds will assist coastal locations like Seattle in getting their normally mild temperatures into the 90s and potentially 100s.
Heat watches and warnings are in place throughout much of the rest of the West as well.
