dry spell

Residents of the greater Puget Sound region have already been feeling the transition to fall with a shift down to lower temps and more clouds last week. But Friday marks the official end of summer, with the autumnal equinox on the calendar.

The National Weather Service issued an excessive heat warning for western Washington and Oregon Wednesday and said the highs in Seattle on Thursday could hit 95 (35 Celsius) while Portland could reach 105 (40.5 Celsius).

Seattle’s above-normal temperatures have been tempered somewhat by a grimy layer of smoke from British Columbia’s wildfires that moved in Tuesday. The influx has made air quality in and around the Emerald City worse than Beijing’s.

Even as the air cools a bit over the weekend, the temperatures will stay far above normal, with the haze dissipating only somewhat and quite slowly, says KNKX weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

A small storm of drizzle spoiled Seattle’s chances to break what KNKX weather expert Cliff Mass viewed as a significant record.

Thursday morning’s precipitation was just enough to be considered a "trace" of rain and cancel the chance for a rain-free July. But there is still a chance to continue a dry-day streak.

Drizzle and light showers fell in a few places this week, especially in the south end of the Puget Sound region. But for most of the region, including Seattle, rain has been missing for more than a month.

KNKX weather expert Cliff Mass says there’s a good chance the emerald city will break a record with this dry spell.

The cold, dry air that’s been pouring into the Northwest and keeping temps well below freezing is coming to an end this weekend. But before the Arctic air completes its exit and things warm up all the way, there’s a possibility of snow in many areas, says knkx weather expert Cliff Mass.

“We have to get through a bit of cold for the next day or two,” said Mass, a professor of atmospheric sciences at the University of Washington.

Dry spell likely to continue in Northwest

Sep 1, 2012

Northwesterners heading out for the Labor Day weekend have a pretty good chance of staying dry. The region is in the midst of one of the driest streaks on record. And there's little chance of that changing soon.

It hasn't been your imagination. It's been really dry in the Northwest this summer. In fact, it's been mid-July since Seattle, Portland and Boise have recorded any measurable precipitation.
