Weather reports on whatever I decide to report on.
A prolonged pattern of upper level troughing and repeated regional storm systems have added quite a bit of snow to mountains of the Pacific Northwest over the past week. As of the end of the day on March 4, the snow-water equivalent (SWE) value for the Northwest was 88% of the median for this time […]
A rapidly intensifying low pressure system is moving north through the Gulf of Alaska on Wednesday afternoon. It is forecast to make landfall on or near Alaska’s Kenai Peninsula early Thursday morning. Off the coast of Alaska, hurricane-force winds are forecast to extend eastward from the Kenai Peninsula toward the southeastern portion of the state. […]
Ridging over the Pacific Northwest on Wednesday along with a strong low in the Gulf of Alaska are driving mostly sunny and seasonably warm conditions in the Portland area. Meanwhile to the north, a Pineapple Express has been aiming at Vancouver Island, producing up to 200 mm (8 inches) of rain. This Pineapple Express is […]
Note: This article is using the meteorological definition for fall, which is September 1 to November 30. The first half of meteorological fall is September 1 to October 15. The weather pattern over the Western United States has been dominated by persistent upper level ridging for several weeks, leading to above average temperatures and below […]
For the first time since November 2019, the Tri-Cities is no longer listed as having drought or abnormally dry conditions according to the National Drought Mitigation Center, which maintains the U.S. Drought Monitor. The scale this center uses starts with abnormally dry (D0) then proceeds from moderate drought (D1) to exceptional drought (D4). At the […]
The weather pattern that is forecast to bring excessive heat to the Pacific Northwest for much of this week may also bring wildfire smoke into the region from fires burning in California’s Sierra Nevada mountains. As of Monday morning, the largest smoke maker out of these is the Oak Fire burning near Yosemite National Park. […]
Afternoon highs in the Tri-Cities have been running above average for the last several days in the Columbia Basin with some places even approaching 70° late last week. These mild conditions are likely to come to an end with a strong upper level trough diving south out of Canada and into the Pacific Northwest. While […]
The drought gripping the Western United States continues to worsen in Eastern Washington. In this week’s update of the U.S. Drought Monitor, exceptional drought (level 4/4) was noted as stretching from the northern end of Rattlesnake Mountain to Sprague Lake, which lies between Ritzville and Spokane. A small sliver of exceptional drought conditions also reaches […]
An unusually strong area of high pressure is forecast to build over the Pacific Northwest during the next several days. The drought in place across much of the West (including the Columbia Basin) also adds a little to what temperatures the region may see. With soil moisture values low, there is little if any water […]
The National Drought Mitigation Center updates their Drought Monitor every Thursday, outlining the geographic details of drought conditions throughout North America. In today’s update, the extreme drought category was expanded to include much of Eastern Washington from the Tri-Cities northeast toward the Spokane area. Previously, only small sections near Prosser and Waitsburg were seeing extreme […]
