The location of the heaviest snowfall varies according to the scenarios considered, along a north-south axis. Significant snowfall could also affect southern Meurthe-et-Moselle overnight from Tuesday to Wednesday.
In addition, geographical disparities could be significant during this episode, with snow intensities of around 2 to 3cm per hour locally and with snow accumulations ranging from simple dusting at 5cm or even 10cm locally.
The south of the Doubs department (to the south-west of Besançon) or the plain of Haut-Rhin (to the north of Mulhouse) remain away from the greatest accumulations of snow.

Snowfalls are expected from Normandy to the Paris basin, “they will give small quantities in general, but we cannot exclude reaching a few centimeters very locally”, warns Météo France. The Paris region would then be concerned only in the extreme south.
On the other hand, late this evening and next night, significant snowfall could be organized towards the Creuse and the Allier then shift towards the southeast.
