The storm is on its way. Sunday Night and Monday you'll see more snowflakes falling. It seems like the impact of winter storms are a distant memory to me, so prepare yourself for this season's first winter storm. It will likely have a big affect on your morning commute.
The NAM forecast below can be viewed at weather.utah.edu. This shows the approach of the pressure trough and the snow delivered to our mountains.
How much snow are we expecting?? We'll need to look at ensemble forecast to answer that question. Below shows the amount of snow expected in Salt Lake as forecasted by a dozen different models...
Another way to look at these ensemble forecasts is by looking at a probability of different amounts of snow. Study the different plots below... The one on the top right suggests all of Salt Lake and Utah County have greater than 90% chance of receiving more than an inch of snow in the next week. Most of that snow will occur on Monday. Mostly the mountains and benches have a high chance of receiving more than 6 inches. And only the highest peaks have a high chance of getting a foot of snow.
It'll be important to keep an eye on this storm, especially if you are commuting into work or school Monday morning. You'll want to give yourself some extra time, or maybe go in late and wait for the roads to be cleared.
