TL;DR: We’ll have a shortwave trough that will move through Sunday night into Monday, bringing around 6-10″. Unstable Northwest flow will be persistent after that with light accumulation through the workweek.

We’ve got some high clouds streaming into the state this evening, setting up for pretty stellar sunset. Here’s what the view currently looks like at 4:40 from Hidden Peak looking west:

Short-Term: Going through the weekend, the ridge that is currently in place will break down from a deep trough off the PNW coast moving inland. Unfortunately, by the time this trough gets to the interior west, it will weaken a pretty good amount and become less amplified.

Even with the weakening, unstable conditions and enhanced northwesterly flow will still be enough to drop 6-10″ in the cottonwoods.

Long-Term: Flow will be generally out of the northwest through the remainder of the workweek, with some weak shortwaves embedded within the flow. This will bring light accumulations through the week. Getting into next weekend, models have been trending to more troughing over the western US. This would benefit Utah greatly with snowfall. Pray to the snow gods this ends up happening!
