Only eight départements were on black ice and snow alert on Thursday afternoon, down from 45 at the beginning of the week, and the sun put in an appearance in the capital.
And it said more snow was on the way, starting as rain over Brittany, in the west, but getting thicker and whiter as it headed east to Normandy and the Paris region.
Between three and seven centimetres was likely to fall, Météo France said, adding that it could be more in some places.
Emergency services reported a steep rise in the number of accidents caused by ice after a night that saw temperatures fall as low as -13.7°C, the lowest for years, in parts of the Paris region.
The chaos in public transport had subsided on Thursday morning and there were only 100km of traffic jams in the Paris area, a third of the average, because drivers had heeded advice to leave their cars at home.
Airports reported normal traffic.
