Hello! First, I want to thank the development and support team at Windy for producing a wonderful product. As a forecaster in the Pacific Northwest, I use this tool on a regular basis as one of my resources to develop daily forecasts. With that said, one feature that would be ideal would be a total precipitable water layer. I know you have a water vapor layer which is helpful but including a total precipitable water layer would make things much easier. In addition, I did want to mention that this has been expressed by other meteorologists in the region who use Windy as a resource as well.
I was not sure if Windy had any plans to incorporate this in the future or was even looking into it, but I thought I would mention it. I want to thank you in advance for your time and assistance in this request.
