After a couple of solid storms over the last two weeks, a drier pattern has taken hold. There's not much to talk about other than when this ridging pattern will break down. We will have a weak system scooting over the ridge in the middle of next week that may bring some light rain and snow to the northern zone, but right now it doesn't look like much. Below is the upper-level pattern for Tuesday through Saturday, showing the small storm.

After that, it looks like another ridge will develop over the region, as you can see below.

There are some signs of more active weather returning as early as the 10th, but the signal is weak at the moment.

My next post will be on Monday.

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.
