24-hour Temperature and Relative Humidity for NearSys Station, 8 December 2018

Our temperatures continue to rise (slightly) as can be seen in the temperature being higher at the reporting period than at its beginning. We're under a high pressure system that will give away to a series of cold fronts. As a result, we are expecting snow sometime Monday. I suspect the snow won't last in the valley with these higher temperatures.

We had a small amount of rain and snow at NearSys Station this weekend. The precip prevented me from placing the photometers outside until noon today. So the extent of the data is more limited this weekend.

We have a break in the clouds that can also be seen in the CloudCam video posted to my YouTube channel (it will get posted tomorrow).
