Strange spikes in the relative humidity were measured on Sunday morning, before sunrise. NearSys Station is far enough away from the yard that I don't think the sprinklers were responsible for this. Otherwise, after sunrise the temperature and relative humidity behaved as expected.
There was odd spike late on the 5th when the concentration of particulate matter increased ten times. The event lasted approximately 12 hours. It can also be seen that NearSys Station was offline during the 29th.
It's a hazy day. Even last night it was too hazy to justify taking the telescope outside. With that in mind, the visibility at NearSys Station is just barely 50 miles. That's because the Boise Mountains can barely be seen from the air.
Saturday started clear, but got partly cloudy during the afternoon. However, it ended well with clear skies. You'll notice the cloudy skies between 11:00 AM and 5:00 PM as the spikiness in the chart below.
