| Snow related to waving frontal system. |
| Synopsis: advection of cool polar maritime air from NW. A waving frontal system over northern France shifted ENE, and the collision with this cool air and some milder air activated this front. With temperatures dropping just above the freezing point, it gave during late afternoon and evening a couple of hours moderate falls of snow, some flakes had dimensions of a couple of cm. Mainly affected were western, central and southern parts of Belgium giving a cover up to a couple of cm, over my area 2 cm was accumulated. All pics taken at Kampenhout in local time (CET). |
Radar sequence between 1900-2050 CET. My location was near "BR". Check also the directional shear of the precipitation belt: in lower levels air comes from NNW, in upper levels airflow is WSW'ly. (Source radar picture: Belgocontrol)
