Many Puget Sound Heat Records Likely To Topple By Monday

SEATTLE — Cities across Western Washington are certain to shatter a few records in the coming days as a prolonged heat wave brings eye-popping temperatures to the Pacific Northwest. A handful of records were already matched or surpassed Friday, including a historic high for Port Angeles.

Forecasters said the three days of excessive heat are sure to land in the record books — it's only a matter of how many will be broken and how significant they will be.

"At first we will break the daily records, and then the June records, and then we will very likely break some all time record high temps," wrote Justin Pullin, senior meteorologist at NWS Seattle.

In Seattle, several major weather records may be toppled by Monday, including the Emerald City's all-time high of 103 degrees, set in July 2009. Officially, Seattle has only broken the triple-digit mark three times. Now, it's forecast to hit the hundreds at least twice, with a chance for a hat trick.

Temperatures around the Seattle metro could soar as high as 112 degrees Monday afternoon and appear most likely to land around 106 degrees at the airport, forecasters said Friday. Similar all-time records may be set in Bellingham, Olympia and elsewhere.

Other records likely to fall in Seattle include a record high for June, a new monthly record for consecutive days above 90 degrees and potentially recording the warmest overnight temperature in history.

Right now, forecasters estimate the low Sunday morning will be around 69 degrees, with a chance it could be as high as 74. For Monday morning, the best estimate is 70 degrees, with a possibility for up to 79 degrees.
