Weather pictures & report of January 24 2005

 

Snow showers on troughline + isolated snow showers.


Synopsis: advection of unstable polar maritime air from the N. During the early morning a troughline crossed Belgium, giving showers of snow. It produced in western parts locally a coat of 4 cm. In my area only a partly cover of 0,5 cm was formed, which quickly disappeared on the diurnal rise of temperature. In the afternoon a few isolated showers came in from NNE, producing "some dust" on the ground. Photos taken at Steenokkerzeel (near Zaventem-Kampenhout) unless otherwise stated and  in Central European Time (CET).

Satellite image of Terra taken around noon is showing a cover of snow over almost the entire Benelux and Cb activity along the coast. The picture also reveals a gap in the snowcover over central & NW parts of Belgium (+ SW parts of Holland) due to lack of active showers during the previous night, so my area (K) had a bit of bad luck. Also the Belgian coast and a bit to the east hadn't seen significant falls of snow but this was due to the higher temperatures over there. (Source: Image courtesy of MODIS Rapid Response Project at NASA/GSFC)

 

07:17 (Kampenhout). Early start of the day for me, but was relative happy ("wanted" a bigger accumulation) to see that there have been some light falls of snow during the night.

 

09:02 SE. In the morning a few isolated dissipating snowshowers passed east of Zaventem airport. Besides the precipitation trails, also a thin cover of snow can been observed. 

 

16:02 N. After a quite sunny day, there was more light shower activity on its way.

 

 16:31 SW. Gradually the sky was invaded by snow flurries.

 

 16:36 N. Visibility was reduced to around 3km, thus categorised under "light snowshower".

 

16:38 N. After 10 minutes, breaks came in from N.

 

16:39 SSW. Cb praecipitatio quickly moving out of the area and leaving only a very thin cover of "dust" on the ground.

 

17:14 SW. Half an hour later a second much weaker snowshower came in. The flurries of snow produced an uncommon sunset.

 

 17:24 NNW. A bit later another weak Cb praecipitatio was visible, and snowed out within half an hour.
