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.
