Final update: July 2, 2021 at 06:10 PDT. Details below. As we head into July, the heat wave that gripped the region over the past week or so is waning.

All-time records may fall in the Columbia Basin with the upcoming heatwave
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 […]

This warning goes into effect […]

Meteorological summer (June through August) is over and that means we have lots of fun new data to pour through! This summer ended up being a mixed bag. We didn’t experience as extreme of heat as usual, but our mean temperature was somewhat above average. Interestingly, we were below average for precipitation. Let’s start off […]
Does a snowy winter lead to an unusually hot summer?
For my statistics class at WSU Tri-Cities, I had to do a research project on a set of data. Having heard repeated statements and questions along the lines of “since it was so snowy this winter, that means it will be unusually hot this summer, right?” When I learned I had to do this project, […]
Excessive Heat Watch issued for Wednesday and Thursday
Well, I’ll start this update off with an apology. In my last update, I wrote about a major pattern change that would essentially mark the end of our 100-degree days for the season. In fact, I’ll even directly quote myself: “This shouldn’t even lead you to believe that we won’t hit 90 again at some […]
