Spring Storm Recap, Dry Days & Cold Nights Ahead

A strong spring storm moved through Washington and most of the Pacific Northwest on Sunday and Monday. The storm brought strong winds, brief heavy rain, and some mountain snow.

Take a look at peak winds in the Lowlands and in Eastern Washington.



Winds gusted 30-50 mph in the Lowlands and 40-70 mph in Eastern WA, with isolated gusts of 70-100 mph.

Perhaps even more astounding is the incredible winds at Camp Muir (10,000 feet up on Mt. Rainier). Winds gusted over 100 mph for 12 HOURS, peaking with an astonishing reading of sustained 119 mph, gusting to 143 mph. That is the strength of a Category 3 hurricane.


Camp Muir is a very exposed location open to the full brunt of storms at a high altitude. It's rare to see such a strong gust (143 mph) anywhere, let alone in Washington State!

Monday was partly sunny, with light northerly winds bringing dry conditions and low relative humidity. Minimum humidity values are below.


Humidity dropped to 25-40%, low for this time of year.

Moving on from the storm, dry days with some unseasonably cold nights are expected. This graphic from NWS Seattle shows expected low temperatures on Tuesday morning.


Temperatures as low as the upper 20s are possible, especially in the South Sound. Additionally, there is a chance of patchy fog/freezing fog, frost, and black ice. Be prepared for these conditions!

Looking ahead, here is the forecast for Puyallup from Weather Underground.


Temperatures gradually warm to the mid 60s on Wednesday (likely our warmest readings of 2021...yay!), with another chilly morning on Wednesday. We cloud up on Thursday, and showers return by Saturday.

Enjoy the calmer weather!
