@ChrisK1954 Your question is strange because isobars with Highs and Lows can be displayed in Windy if you enable them (Pressure isolines). [image: 1763021551644-faae4a0b-bf69-4529-90c4-09b18e350cad.jpeg] Wind/w customized color scale As explained many times, Windy cannot display fronts because weather models are not capable of plotting them. This work is done by meteorologists. And Windy is not a Weather Center employing a team capable of plotting fronts across the globe on an hourly basis.

@Dale-OBrien We don't have such plans in the near future. Sorry.

@idefix37 Thank you! Until now I hadn't seen that there were different forecast panels! This is fantastic! I'm still hoping they will add an alert option for pressure though.

@jehol12 Hi, may I ask which layer do you use as a default one?

@graigbefathered said in Uncertainty on Atmospheric Pressure: what the uncertainty (or error) on the pressure readings What Windy shows is not reported pressure, but forecast pressure. The pressure shown by Windy is predicted by the model after interpolation between grid points It is the first cause of error. If you look at the pressure values by the different weather models at your location, you will get an idea of the uncertainty. Personally I would prefer to use the pressure readings at the nearest professional weather station to your location. Reported pressure at weather station is not displayed in Windy.
