How do I change model of the meteogram? It always seems to get data from ICON 7km despite the model selected for map overlay. (iOs version)

Forecast data cannot be currently changed. They are taken from ICON (regionally from ICON-EU or HRRR) and for later dates from GFS.

I wasn’t aware of this limitation as I moved from Windy, now I’m severely disappointed, as ICON is very (and I mean very!) incorrect in the mountainous place I’m usually at.
Is there a plan to fix this and model to be selectable in an automated and manual manner, same way as the map is?

Could you please clarify which model is used in the meteogram ? You mentioned ICON and HRRR. I live in the US East Coast.

Also, I see some discrepancies between the information presented in the map, in the detailed meteogram and in the forecast bar at the bottom of the iOS bar. Why?

For the first few hours it’s HRRR, then ICON, and from 8 days onward GFS for this location. I am sorry, but I can’t explain the differences without a screenshot.

Here is an example. The forecast card says 19 kn while the chat shows 16kn

At least the forecast and the meteogram are matching.

It could be a slightly different run of the model. HRRR updates every hour, so it can happen that it’s already processed for the map, but only after 10 minutes it gets processed for the forecast. That can cause a difference.

Hello, i live in masnou (near Barcelona). I think you use icon but you use Icon for all time. Aladin or Harmonie or arome are better for inicial hours

For exemple, in Barcelona (a coast city) For optimal meteorological forecasting in the region, it is preferable to use HARMONIE-AROME, or ALADIN if HARMONIE-AROME is not available, during the initial 48-hour forecast period. For forecasts beyond 48 hours, the ICON-EU model should be used (between 2-4 day).. Belong 4-5 day IFS (from ECMWF) is more acurate

I suppose you're using ensmbles only with icon-eu and this is the reason you're using this model in your forecast, but icon-eu for near sometimes isn't good (hyperlocal with coast and mountain orografy)
