Weather reports on whatever I decide to report on.
The warmest day of the week was able to produce record highs in the Tri-Cities and Walla Walla on March 19. Additionally, Hermiston tied their existing record for that date. Low elevation spots on the Hanford Site, around the Tri-Cities, and in the Hermiston area were able to tap 80°F (27°C) with widespread 70s (21-26°C) […]
Tuesday is likely to be the warmest day of this weather pattern for the Columbia Basin with the Tri-Cities reaching into the upper-70s (26°C). Temperatures in some areas west of the Cascades peaked on Monday. Portland recorded a high of 77°F (25°C), a new record for March 18, while Seattle peaked a few days ago. […]
Upper level ridging continues to dominate conditions throughout the Pacific Northwest. This has produced highs above 70°F (21°C) in many lowland locations over the weekend. Quillayute, near Forks on the Olympic Peninsula, even recorded a high of 80°F (27°C) on Saturday. The Tri-Cities joined the club on Sunday with a high of 73°F (23°C). March […]
Friday brought Portland’s first afternoon with temperatures above 70°F (21°C) for 2024 with a high of 71°F (22°C) at Portland International Airport. Numerous other stations throughout lowland areas of Western Oregon and parts of Western Washington also achieved 70°, though the Puget Sound Region missed out. This comes as a ridge of high pressure builds […]
Leftover moisture and cold air aloft will be enough for scattered showers and isolated t-storms throughout the Pacific Northwest on Tuesday. These storms will be more widespread along and west of the Cascades and some may produce small hail and/or graupel. The Columbia Gorge, Hermiston, and the Tri-Cities will be breezy Tuesday into Wednesday as […]
The third system in a train that started late last week is forecast to reach the Pacific Northwest during the day Monday. High clouds from this are already reaching the Interstate 5 corridor as of 07:00. Rainfall totals through Tuesday reaching half an inch (10 mm) are forecast for Portland, Seattle, and Vancouver with higher […]
Strong El Niño conditions were observed over the winter of 2023-24, leading to long lasting periods of split flow in the jet stream aimed at Western North America. This is a typical El Niño pattern, where the northern split persistently aims storms at southeast Alaska and the southern branch aims at California. Despite this, Oregon […]
Much of the Northwest is enjoying a break in precipitation after persistent regional storms and post-frontal showers. A low pressure system heading for Alaska will bring that to an end from north to south with the first of several cold fronts moving in. Rain and mountain snow from this begins during the day Thursday for […]
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 […]
The Sierra Nevada mountains of California and Nevada are experiencing a rare extreme blizzard this weekend with incredible amounts of snow and strong winds forecast through Sunday including major travel corridors like Interstate 80 over Donner Summit and the Lake Tahoe area. Storm total snowfall may approach 11 feet (3.4 m) in some spots and […]
