<![CDATA[Total precipitable water]]>The new updates are, as always, great and add a lot of value to Windy. I'm once again asking you to add total precipitable water as one of the parameters offered for display. It's a great way to visualize moisture plumes and whatnot, such as this one later this week where moisture sourced from the Caribbean will be bringing rain to Norway and the United Kingdom.

This sort of thing is critical for severe weather and atmospheric river forecasting and the current humidity and precipitation parameters don't capture it as well as total precipitable water does.

Hi, I am hoping that your colleagues are down with actually creating a feature here, anyone serious about meteorology would appreciate and use these layers. RH is just not useable over total column , Thanks

Adding both would be great. Water Vapour imagery and Total Precipitable Water forecast parameter.

So what Mark Ingalls wants is forecast precipitable water. What I want is real observed precipitable water, a derived product from satellite observation. See https://cw3e.ucsd.edu/satellite/

Precipitable water is observation layer.

Look at the screenshot in the first post of this topic.

Precipitable water is observation layer. @Filip_K

We are not planning to add the total precipitable water product at the moment. This moisture indicator can be partially substituted by products such as relative humidity at various atmospheric levels (from the surface up to 150 hPa), as well as cloud cover or precipitation. If you have any further ideas or feedback, please let us know. Thank you, Jari

I definitely agree that this is desperately needed as an option for windy.

I know it can bring valuable use to windy. This layer can basically use the entire atmospheric column and then imagine if all that air condenses, that would be how much rain it could fall down. This also can be used for determining if it's a tropical rainstorm or a more temperate/wintry storm.

Just saw this post, I totally agree, it would be a valuable and appreciated addition.
