| Radar picture of November 19 taken at midnight CET.
The cold (or polar) front is reaching central Belgium, shown as the thin orange
line, which resembles to a Narrow Cold Frontal Rainband (NCRF). The passage of
the front had a quite distinct wind shift, going from SW to N in a
couple of minutes with gusts of almost 40 knots. Within an hour temperature
dropped from 9°C to 4°C. The previous 20 hrs saw
almost continuous rainfall and I collected within 24 hours 41mm. The first wintry showers
invaded my area around 06:00 CET. (Source: Belgocontrol)

thunder over my area. (Source: NOAA and University of Bern)

13:14 ENE. Back side of a large wintry shower with weak mammatus features.
|
 |
|
13:20 SW. On the other side some small showers developed (Cb cal) giving
trails (virga) of wintry precipitation.
|
 |
|
13:30. This shower produced wintry precipitation with the largest
"stones" having a size between 6-10mm diameter, thus being called "hail".
The ones below 6 mm are being called "soft hail, snow pellets or
graupel". These precipitation forms were photographed after half an hour
lying on the ground.

 |
|
13:46 N. Next shower turned up and although not giving any precipitation
in my area it produced some nice views.

show.
|
 |
| 15:01 NW. This small shower formed and "snowed
out" within an hour.
|
 |
| 15:48 NW. This nice looking Cb capillatus incus was the last
one giving some wintry precipitation over my area.
