Normal Spring Weather, Abnormally Dry Conditions Continue

Tuesday and Wednesday were partly sunny with scattered showers and even a few lightning strikes. Parts of the area received some rain, but generally less than 0.2 inches.

The drier than normal trend will continue through the next few days. Below is the Puyallup forecast from Weather Underground.


No rain through the next 5 days, with another cool day on Thursday, then a warmup to the upper 60s-low 70s. The temperatures will drop back to the mid 60s on Sunday. A couple chilly nights (for May) are expected overnight Wednesday to Thursday and also into Friday. Temperatures will drop to the low-mid 40s, even lower in some outlying areas.

Notice something about the forecast? No rain for the next 5 days (and more). This is part of the overall dry spring that we’ve been having. Below is a graphic from the NWS Climate Prediction Center showing percent of average precipitation expected from May 27-June 2.


Notice Washington is in the 33-40% below average range.

Although there are worries about drought in the Pacific Northwest, below is a graph from the US Bureau of Reclamation showing current water levels on reservoirs in the Yakima River system.


You can see that the level is increasing now, due to the snowpack melting down from the mountains. We are currently above average and very near 2020’s level. Water supply won’t be an issue this summer...you can thank a huge snowpack for that!

One enjoyable thing about spring weather is the puffy cumulus clouds (sometimes cumulonimbus clouds) that build up due to heating in the atmosphere and on the ground...check out the anvil top on this cumulus cloud on Wednesday.


Since that cloud developed an anvil, you could argue that it was a cumulonimbus cloud. Below are some other cool cumulus clouds from Tuesday.


I took both these photos from Federal Way, looking west (upper photo) and northwest (lower photo).

Enjoy the spring weather (and cloud-watching)!!
