Heads up, there may be fresher snow! Read the latest Utah Daily Snow

Snow Showers Today, High Pressure with Scraps

Summary

A weak system will enter Northern Utah today and bring the threat for light snow showers today and tonight. Accumulations should be very light. We will have a couple additional weak storms on Saturday and again Monday. Pattern change looking likely later next week.

More storms. More resorts.

Everyone has their favorite Utah resort. But did you know that no two storms fall the same? That’s why it’s worth checking the forecast and report to see where the deepest turns are going to be. Explore all of Utah’s resorts at VisitUtah.com

Short Term Forecast

We have another "strength-challenged" system that will brush far northern Utah today. I've already seen some snowflakes on various webcams. I expect those to increase as we head into this afternoon. Accumulation today will be very light as evidenced by the NAM output below: 

The Bear River Range in the north could see 1-3" today. Otherwise, the rest of use farther south are looking at zilch to maybe an inch. 

We will have a break Thursday and Friday. A weak system for Saturday could bring the threat for light showers again to northern Utah. Accumulations unlikely to be more than an inch. Then, a break Sunday with another system timing for around Monday. This system is slightly stronger in the GFS, but weaker in all other models. 

These systems are so weak that it hurts my soul to even mention them. They are unlikely to do anything for us besides bring clouds and maybe tease us with a few flakes. The next week in general is pretty dang dry. Here is the next 7 days from each major model. 

GFS: 

This is the best model because it's a bit stronger with the Monday storm. Unfortunately, it's an outlier right now and I have very little confidence in it. 

Euro: 

Euro is the weakest model and has only traces of snow with each system. 

ICON: 

Canadian: 

Both the above models are somewhere in between the GFS and Euro. Really, this is just a lot of information to tell you one thing. We might have a few "storms" in the next 7 days, but that doesn't mean we will get any meaningful snow. 

Extended Forecast

We are still tracking a pattern change that should take place later next week. A trough is going to dig into the central US. The ridge over the west will subsequently move west over the pacific and allow the trough and storms systems to gradually dig farther west. So far, we are still waiting on 10-day operational runs to pick up on individual storms, but the ensembles remain in remarkably good agreement. Here is the GEFS mean height anomalies: 

And the Euro ensembles for the same date: 

Like I said, very good agreement considering we are still 12 days out. The questions we have now are 1) will this pattern hold as we get closer? We've seen models back off of major pattern shifts already this season, and 2) will this pattern have good storms? In theory, the door is open for storms, we just need them to actually show up. 

We will continue to watch and hope!

OpenSnow Forecast Data Update

On Tuesday (1/12), we began updating the automated forecasts on OpenSnow with a proprietary blend of data from the GFS (American), GDPS (Canadian), and ECMWF (European) weather models.

Previously, we combined information from our local forecasters, the National Weather Service (NOAA), and data from the ECMWF (European) weather model. This method only provided hourly data for the United States and relied on a single model to produce our snow forecasts for the next 10 days.

Why is this new forecast data better than the old forecast data? The benefits include:

  • Blending multiple global models increases accuracy and confidence in the forecast.
  • Hourly data for any location in the world.
  • Proprietary snow-to-liquid calculation to improve accuracy, especially in colder environments.
  • Improved method for calculating the snow level (elevation that separates rain from snow) to provide a more realistic forecast, especially at the beginning of storms and during times of intense snowfall.
  • Ability to create a forecast for any location and elevation to ensure that we are forecasting conditions on the mountain and not for a nearby town.

We also plan to add even more global and high-resolution models into our proprietary forecast blend over time. Our goal is to create the most accurate snow forecast and we're just getting started.

The data can be viewed as hourly forecasts for the next 5 days and daily forecasts for the next 10 days. Available data includes:

  • Chance of Precipitation
  • Day & Night Snow Forecast
  • Day & Night Snow Level
  • Daily High & Low Temperature
  • Hourly Temperature
  • Hourly Wind Speed
  • Hourly Wind Gust
  • Hourly Cloud Cover %

This new blend of forecast data is available on OpenSnow for over 2,000 locations around the world and we are adding new locations every day.
