Sunshine and Powder

Posted Monday, December 3rd, 2018 by Alex Weech

As this crazy storm cycle winds down, we get to enjoy some December sun for a bit. The Cottonwood ski resorts are reporting 9-15″ over the weekend, and more showers fell this morning adding to the total. Now high pressure has built in and the sun has come out in the valley. We’ll get to enjoy another day of sunshine tomorrow before the clouds come in again.

The next storm system is similar to some of the ones we saw last week but weaker. A storm is approaching California from the west, and it will bring significant rainfall to parts of the southwest. There will also be precipitation at the boundary between this moist storm air and cold air that moved in with the last storm. Unfortunately, this boundary will be to our north, so the best snowfall totals will go to the Bear River Mountains. Down here it’ll start some showers in the mountains to keep things fresh and then move on. Not that places further north will get very much–just a few inches. At the very least this storm should help stir up the stagnant air a bit. The graphic below shows how relatively moist the atmosphere will be Wednesday afternoon, and the snow will be where the moisture is.

After Wednesday, there will be a few more days of clouds and light showers as the storm system passes to our south. Then high pressure builds in for the weekend again and we’ll get some more December sunshine.
