Low indoor relative humidity and subsequent snow event
Is your skin dry and cracked? Have a dry cough? Getting a little static when you touch that door knob?
These are all symptoms of low relative humidity that develop when outdoor temperatures turn cold.
To illustrate, check out the relative humidity in homes around Seattle, courtesy of the PurpleAir network. Many indoor locations have relative humidity below 30%, some lower.
The relative humidity outside is much higher. How can that be? It’s all explained in my podcast (see info below).
And in the first segment of the podcast, I talk about the weather forecast. Another snowfall will happen tonight and tomorrow morning, but not as much as two days ago.
As shown by the total snowfall predicted from the high-resolution UW WRF system, most of the snow will cover the Olympics and Kitsap Nationals, with northwestern Washington (especially Whatcom County) seeing partial snowfall.
