Around the half of movie, Elara and Gabriel enter Troy's cafe. It doesn't snow outside. They come into and meet with Chelsey. Behind them are large windows. But now there is a heavy snowing on the right window, and no snowing on the left one.
The movie takes place just before Christmas, and it was shot in the winter. However, there is a small difference between mid December and late February / early March - you can hear loud singing by singing birds in the outdoor scenes, and they don't sing between early autumn and late February or early March. Furthermore, in the one outdoor scene, Elara and Gabrial are walking and behind them are several bare deciduous trees, but they are actually starting to bloom.
