24-hour Temperature and Relative Humidity for NearSys Station, 6 September 2018

The Amprobe TR-200A was left outside beneath a sunshield for 24 hours. The air temperature in Boise was about 10 degrees cooler than what the Amprobe measured. So, the sunshield may not be working as well as I hoped. That or it really was 105 degrees in the backyard yesterday.

Weather for NearSys Station, August 20198

There was no precipitation during August. So I didn't post a chart for it.
The ground temperature is in a cooling trend this month.

I don't know if this is to be expected, but the average air pressure has trended upward slightly upward this month. 

No real overall trend this month, the relative humidity fluctuates as it always does.  

Definitely on a cooling trend.
