South America Daily Snow

A Powdery Opening In the North
Summary
Opening day at Valle Nevado was a powder day, and La Parva and Nevados de Chillan will open today with a lot of recent snow as well. A few more dry days are on the way this week before active weather returns Friday night, with accumulating snow possible, especially in the central zone.
Short Term Forecast
Storm totals in the north ranged from 1 to 2 m during the last storm cycle. With most resorts still closed, reports were unavailable farther south. Nevados de Chillan piled up around 2 m of new snow while Valle Nevado, La Parva, El Colorado, and Farellones clocked around 1.1 m.
Cerroy Bayo opened yesterday (6/17) and several other resorts are opening soon:
- El Colorado: June 19
- Coralco: June 19
- Portillo: June 21
- Las Lenas: June 28
Wednesday through Friday will be dry and calm, but the break won't last too long with the next storm moving in on Friday night. The latest guidance still keeps this storm far enough south that the biggest impacts would be in the central zone.
Another storm is possible early next week, on Monday, that is expected to take a similar track over the southern tip of the continent. The models show a trailing wave behind this upper-level low tracking through the northern zone, but confidence remains low at this time. Below is the upper-level pattern from this Friday through next.
Below is the latest snow forecast from the European model for the first storm, impacting the region from Friday night through Sunday.
Extended Forecast
Nothing stands out regarding storms in the long range at this time, with ridging off the southwestern coast keeping storms mainly to our south.
Next post on Friday.
Thanks for reading the South America Daily Snow!

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.
