| Showers of snow. |
| Synopsis: at 500 hPa an Omega pattern with a ridge over the Atlantic and a sharp upper trough over Scandinavia. At surface over Danmark a low of 983 hPa and SW of Eire a weak ridge of 1016 hPa. Thus, in between, Belgium at all levels in a NW'ly airflow of unstable air in which temperature at 850 hPa was -8°C and at 500 hPa -30°C. Thickness 1000-850 hPa = 128,5 dam, thickness 1000-500 hPa = 519 dam. Postfrontal, during a period of 24 hours, wintry showers were advected into the Low Countries. During the night they remained quite active due to a strong jetstream of 120 kt overhead. Sometimes even a "street of showers" was formed giving in Flanders locally a cover of up to 10 cm, in my area 4 cm was measured. All pics taken at Kampenhout in local time (CET). |

Satellite picture (visual) of 25/03/2008 at 1140 LT. The NW-SE orientated white band (between the red arrows) was a cover of snow which was formed during the previous night after the passage of a street of wintry showers. Just inside this area, my location at red "K". (Source: Image courtesy of MODIS Rapid Response Project at NASA/GSFC)
