Satellite picture of Aqua taken around 13:30 CET. My position is at "K". Compare it with my picture taken at 14:04 CET. This was the shower just north of my position. The second line of showers was at that moment over southern parts of the Netherlands (at "2"). (Source: Image courtesy of MODIS Rapid Response Project at NASA/GSFC)

 

Corresponding radar image of 13:45 CET. The shower just north of my position at "BR" produced even a rumble of thunder. Tops went up to 6km. Check also with my photos taken at 1404 and 1425 CET. The second line of showers is noted as a "cluster" over S-Netherlands. (Source: Belgocontrol) 

 

14:04 N. Pregnant sky with snow in the air. When reaching ground it was rather rain and sleet.

 

14:25 ENE. The shower had even a rumble of thunder on board. The back of it showed mamma alike structures.

 

14:26 WSW. On the opposite side a burst of wintry precipitation (small hail) was still falling.

 

16:11 NE. Another shower with virga came in from north.

 

16:15 ENE. Low cloudbase of the same shower.

 

16:17 N. It was in fact a line of showers. With a N'ly airflow we wouldn't escape from it.

 

16:22 N. A few moments later, skies were darkening.

 

16:26 N. It was for a moment a very nice view. The shower self did produce only a few flurries of wet snow.

 

16:38 WSW. Passage of the showery line with bursts of wintry precipitation (mostly "graupel"), reaching or not reaching the ground. A towering cumulus can be seen vaguely.
