Windy launches "Observation vs. Forecast"
That coloured area represents the observed temperature on the upper side and the dew point on the lower side measured by the weather station. And its colour is corresponding to its colour scale depending on its value.
You can note that the more closer these two lines (values) to each other, the more saturated is the air. Obviously when the two values are equal --> the air is 100% saturated in this case (it's depicted on windy as a very little gap between the two lines, but above the chart at the value indicator you can read 2 equal values). In this 100% saturated air, the air contains a lot of moisture and there exist a low visibility condition, due to the very high probability of fog creation, which can transform into a low level stratus cloud with the help of a little wind. So it can influences the developing weather phenomenas.
Anyway, the other 2 dashed lines represents the forecasted TEMP and DEW POINT, for that weather model, which you select at the bottom of the chart.
Or if you are thought about the starting pop up charts and not the weather stations' "observation vs forecast" charts, there the coloured area represents only the forecasted temperature, as you can see it below.

Usually most of the forecasters use the European model forecast predictions!

@csabatatar Such a good explanation, csabatatar, thank you very, very much. It was indeed the "observation vs forecast" representation that I didn't understand. And now I do!!. Thank you!

... as a guide line.
For more detailed forecasts they use (local) Limited Area Models.

Thank You ! Good Job(or hobby)!

I am really having trouble with this feature, cause I cant find it. Can someone help me pls?
Just select « Reported wind » or « Reported temperature » to display the weather stations near your location. Then click on the weather station you want to compare the observations of this WS and the forecast by each models used by Windy.

Terrific. Useful to see the actual vs the predicted for an estimate of the accuracy.

I love it. Looking forward to seeing colours in the above zero Celsius range locally.

I don't like it, it is important to me to see the graph of the observed wind and gusts just like it was before, that way you can see trends and make reasonable predictions. PLEASE bring back the old style plots or at least make an option for people to revert to them if they want to. I will be switching to Windalert for the time being, it's a shame Windy was perfect for me before this update.
