Forecast for the next 24 hours:

This is my thunderstorm outlook for Belgium, The Netherlands, Luxemburg, Germany and France. The colours on the map indicate the strength of thunderstorms expected in a period of 24 hours. You can find the exact date and hours for the forecast on top of this page.

Beside the coulours there might be some coloured lines visible on the map. When a black zone is drawn, that means that there is a chance that one or more tornadoes might occur within that zone.

A blue zone is a large hail warning. Within the blue zone large hail may occur. You will see a number on the blue line, that is the maximum diameter of hail size expected (in centimeters).

My forecasts are based on:

- GFS model maps from Wetter3.de

- NCEP GFS model maps from Lightningwizard.com

- Sounding & Skew-T from NOAA
