Where’s the sun ? Patience… Happy birthday Alix and have a good weekend!
All over the region the visibility is poor this morning. Mist and fog banks (generally not very dense) have formed during the night and can in places where it is coldest be icing, so beware of slippery roads! (also note the risk of freezing on wet pavements).
All this grayness will slowly evolve in the morning, it is almost necessary to wait until midday for some clearings to develop on the coast. The wind this morning is variable and it remains weak.
The afternoon should bring us a favorable evolution, even if the clouds remain numerous the sun will still make appearances, and for you who live in the south-east of the region, it is even beautiful clearings that the Weather forecast France ! However on the littoral fringe, from the Belgian border to Boulogne, some scattered showers can occur.
At daybreak it will be very cool in the region, the minimums range from -2 ° to + 1 ° (locally -3 °), hence the slippery phenomena, as for the maximum temperatures they will remain stationary on the coast (from 5 ° to 6 °) but are falling in the interior since it will not be more than 2 ° to 3 ° at the best of the day.
Conditions will be high pressure. After the morning gray has dissipated (faster than today but still with the risk of freezing fog), the day will unfold under variable, mostly cloudy skies. Dry weather therefore, but cold, since it will undoubtedly be the coldest day of the week. To note in the course of the following night, very quickly, the formation of mists and mists.
To start the second week of the year, the whole region seems to be waking up under the gray. Freezing fogs will still be present, especially over the southern half of the region. Then it will be dry but rather cloudy before the clouds of a disturbance arrive which should start to water the Opal Coast in the evening. It will still be cold in the morning with almost generalized frosts (down to -4 ° in the Aisne) but with the flow going to the west, the maximums will gain two to three degrees compared to Sunday.
The disturbance that will have spread throughout the region overnight will remain with us all day. So let’s expect a gloomy, rainy day, but much milder since the day’s temperatures will rise again, morning and afternoon, two degrees above the seasonal values.
► Air quality
Air quality is expected to be poor over the center of the region as well as on the Gravelines side. The cause is an increase in PM2.5 particle concentrations linked to poor pollutant dispersal conditions. Regarding the rest of Hauts-de-France, we should have average to degraded air quality.
