Weather reports on whatever I decide to report on.
From about November to February temperature inversions accompanied by low clouds and fog are a common weather feature in the Columbia Basin. These are not unique to the Columbia Basin with many valleys throughout the Western United States and the world also experiencing strong inversions, including the Salt Lake City area in Utah and Almaty, […]
Showers were already being observed in the Columbia Basin and Yakima Valley before 04:00 Monday thanks to an upper level low pressure system centered near Central Oregon. This pattern is pulling moisture up from the southeast in a setup similar to what occurs during monsoon season late in the summer. I’m labeling it a fake […]
Ridging is building over the American West today into the weekend, leading to a regional heat wave in the Pacific Northwest. Above average temperatures are forecast for the Columbia Basin, though things aren’t looking quite as warm as they were originally expected. The Tri-Cities can expect a high in the mid 80s on Friday and […]
Tri-Cities weather • Friday, May 5, 2023 Expect mostly cloudy skies throughout the day with off and on light rain showers. With the San Francisco low that drove our conditions most of the week having moved off toward the northeast, we no longer have warm moist air being pulled in from the south. This takes […]
Tri-Cities weather May 4, 2023 Partly cloudy skies to start the day. These are mostly high clouds drifting north from thunderstorms in mountains to the south and east. Increasing clouds for the remainder of the day which will moderate highs compared to yesterday. Look for temperatures reaching the mid to upper 70s. The Storm Prediction […]
Mostly clear skies through the morning hours with temperatures starting in the upper 40s in the Tri-Cities area. Upper level low pressure remains in place, centered near San Francisco. This is forecast to continue spinning moisture into the Inland Northwest today and tomorrow. The moisture from the San Francisco low will likely generate a few […]
Tri-Cities weather – May 2, 2023 A strong upper level low pressure system centered near San Francisco this morning is driving the weather pattern over the Pacific Northwest today. In the Columbia Basin, this is likely to produce intermittent clouds and sun along a fairly narrow band. Previously, temperatures were forecast to reach into the […]
Toward the end of the Last Glacial Maximum, catastrophic flooding surged down parts of the Columbia River watershed as natural dams creating large lakes failed. Some originated from Glacial Lake Missoula, which was created by a large dam of ice in Montana and Idaho that periodically failed. These, often termed Missoula Floods are probably the […]
A low pressure system slowly moving offshore is forecast to spin moisture into the Columbia Basin Sunday as it meanders closer to the Southern Oregon Coast. This has prompted the National Weather Service to issue a winter weather advisory for the Tri-Cities, Walla Walla, Hermiston, and surrounding areas in effect from 04:00 to 22:00 Sunday. […]
Colder temperatures are swinging into the Pacific Northwest out of British Columbia and Alberta with a brisk north to northeasterly breeze forecast on Tuesday. Those winds die down early Wednesday morning and despite mostly sunny skies temperatures aren’t likely to hit 40° that afternoon. Again under mostly clear skies, temperatures are forecast to get quite […]
