According to an article in Sunday's Seattle Times, not until July...maybe.
Meanwhile, in today's Seattle Times, it is reported that:
Seattle just experienced the coldest first week of June, according to climate records dating to 1891, said Cliff Mass, University of Washington meterologist. Both 1999 and 2008 share the record, with 1917 falling in second place, he said. "Just wait until tomorrow," he said, when temperatures are going to be even colder.Mountains in Eastern Washington and Northern Idaho are also expected to see snow above 3,500 feet.
"In 30 years I can only remember two other times when it snowed this late in the season," said Sam Krahenbuhl, Snoqualmie Pass assistant maintenance superintendent. "One time it snowed on a Fourth of July weekend. This is really rare."
While it won't snow in the Puget Sound area, records for the lowest high temperature may be broken today and Tuesday. Forecasters said the high temperature today should be 57 degrees, 1 degree below the record set last year. On Tuesday, under windy and rainy skies, the temperature should only get to 54 degrees, 2 degrees below the record set in 1972.
Remember, there's only 7 years, 7 months and 19 days until the The Goracle predicts the Earth will melt......
