What does the colored graph area between the time and the temp represent?
-
@jsdhornby
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!
-
@LAR-48
... as a guide line.
For more detailed forecasts they use (local) Limited Area Models. -
@ivo Marvellous and impressive. Keep it up.
-
Great feature! I love it
-
"Observation vs. forecast" information is nowadays a MUST! Well done!
-
Give us the old style back pleaseeeeeeeeee !!!!!!!!
-
awwsome could someone please explain how to read it all? why doesnt it show the rain icon or a sunny/cloudy icon all the time?
-
Like it a lot makes it quicker and easier at a glance
-
I like it! very cool to have it up on the screen. Well done team!
-
Doing a Bonzer job ,keep up the good work
-
Very nice! Would be even nicer if you can compare to all forecasts in one window!
Thank You ! Good Job(or hobby)! -
I am really having trouble with this feature, cause I cant find it. Can someone help me pls?

@Gabriel-Ramiro
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.

Really like it, very interesting
