Therefore, in the morning, the weather is calm with morning frosts and a hazy sky. Precipitation arrives from the south during the morning, reaching the Somme valley by midday.
In the afternoon and especially in the evening, this precipitation spreads across the entire region. This is wet snow, which arrives on cold ground, with significant accumulations which could give 1 to 3 cm in Picardy before the warm weather in the afternoon, but 5 to 7 cm in the North and the Pas-de-Calais which could hold on to the ground during the night from Wednesday to Thursday. The southerly wind is weak then southeasterly at the end of the day, strengthening, it turns to the northeast over the north of the region and to the southeast over the south at the end of the day.

This Monday, January 6, concentrations of pollutants remain low thanks to rain, winds and gusts. The air quality index remains at an average level in the region, ozone and fine particles (PM2.5) are the pollutants responsible for it.
And to keep good air in your home and also limit external pollution, know that your chimney flue must be swept twice a year.
