I have 4 different weather apps on my iPhone, and usually they are all fairly close to each other in the current temperature. However, lately, the Windy widget is way off from the others. Currently (12/31/24, 11:02 PM MST), Windy shows 10 deg F, the other app shows 26 deg F.

Further testing determined it was the forecast model. I changed it and now the temp is showing within a couple of degrees of other apps. However, when I open the app, the forecast model changes back to the ECMWF model and the temp is wrong again. If I click on the home button, the top bar comes up wrong, but when I click on the top bar to open the extended forecast, it shows correctly. How do i get the correct model to stay as default? Why the discrepancies?
