Now this all gets a bit technical... GFS Forecasts
These are GFS (Global Forecast System) ensembles which are models from different weather prediction systems produced at the same time. This graph is for La Tania (or at least 45 degrees Latitude, 6 degrees Longitude which is pretty close). Updated every 6 hours or so.
Bottom lines are precipitation and top lines are temperature forecast at around 1450m (850hPa, the altitude depends on pressure). La Tania base is approximately 1400m.
Red is a 30 year average. Blue is the control line. Gray is a consolidation.
When the lines are all close together the forecast should be more accurate - for snow look for peaks downwards heading below zero from the top lines and peaks upwards from the bottom lines, showing the forecasted amount of snow.
