Sunday was another powder day across the northern resorts, reporting 15 to 30 cm. Snow was piling up in the central zone as well, but reports were limited. Monday will be mostly dry before the next system arrives on Monday night. 

A series of upper-level lows will move through the region over the next five days, bringing periods of moderate to heavy snow. This will favor the central and southern zones with limited impacts in the north. The southern part of the central zone should do best during this period, with chances for snow continuing from Tuesday through Saturday/Sunday. 

Below is the latest forecast from the European model through Sunday evening. Totals in the northern zone and the northern part of the central zone should be limited unless the storm tracks farther north.  

This series of storms will also feature strong winds, especially in the southern half of the central zone. Gusts could reach 40 to 80 km/hr with sustained winds in the 20 to 40 km/hr range. Temperatures will be a bit warm on Monday night and Tuesday before the cold front arrives, but on Tuesday night, snow levels will fall well below the bases. Snow levels will rise slightly on Wednesday night as the next system approaches, but are expected to remain below the bases for the remainder of the period. 

There are some signs of a storm for the north early next week, but the models are not aligned. 

Next post on Friday.

Thanks for reading the South America Daily Snow!

NEW: Forecast Range Graphs

You can now view individual forecasts from global and regional high-resolution weather models in OpenSnow. This includes forecasts from the GFS, ECMWF, HRRR, and ICON models, as well as the OpenSnow blend.

The graphs give you a behind-the-scenes look at the forecast and make it easier to see if the forecast models are in tight agreement or if there is a wide range of potential outcomes over the next 10 days.

Note: This is currently only available in the OpenSnow iOS app and website (OpenSnow.com). Android will be available soon.

Getting Started

1. Go to any location screen.
2. Scroll down under "Weather" or "Snow Summary".
3. Tap "View Interactive Chart" in the app.
4. Adjust the model, timeframe, or data view.

Why is the Forecast Range helpful?

Understand if there is high or low confidence in the forecast. If all models show a similar forecast, there is higher confidence in the forecast, and vice versa.

Dig into the details. If you have experience looking at weather model data and trust certain models or higher-resolution models, you'll be able to isolate your favorite data.
