Thanks!

So 1-hour time steps for 3 days.

@vsinceac
Where it says 1-hour forecast, does that mean 1-hour time-steps in the forecast? And if so, does that cover wind, rain, clouds, etc.? And for how many days out is the 1-hour time-step granularity provided?

What does a premium subscription add compared to the free version?

@idefix37 the isolines appear to me to be MSL while the graphical display seems to be AGL. If you look at Isolines even crossing the Rockies you don’t see any real impact of surface elevation. Again I wish the reference was specified in the name of the option in the App. For example instead of Freezing Alt, Say Freezing Alt MSL. Without knowing the reference the information can be dangerous for a pilot since it can be off several thousand or even 10,000 ft.

@korina I don’t know why the second image is so poor but it shows the same area with the pointer moved along the same 5400ft isoline to a position west of the mountains.

@korina ok so I’m uploading two screenshots. Each highlighting a different position on the same 5400’ Freezing Alt Isoline.

@tembek I’m trying to upload a screen shot but keep getting an error message. Is it because I’m a new user?

I’ve noticed that the Graphical depiction of Freezing Altitude differs significantly from the Freezing Alt isolines particularly when an isoline is crossing an area of changing terrain (such as a mountain range). Is one AGL and one is MSL? It would be nice if the alt reference was noted on the app for all altitude figures (Freezing Alt, Cloud bases, cloud alts, etc).
