I spotted some unusual mammatus clouds overhead this afternoon. They’re unusual because normally mammatus are associated with strong thunderstorms. In this case there are just some rain showers in the area. #mbwx

Watching an area of thunderstorms that are developing over southeastern MB. These storms are being triggered semi-parallel to a stationary front over northern Minnesota. Should they continue to expand tonight, locally heavy rain is possible at they move slowly northeast. #mbstorm

Training thunderstorms produced heavy rainfall exceeding 100 mm (4 inches) in southern Manitoba overnight. Training storms are analogous to a freight train, as storms repeatedly pass over the same location. But why did this happen?

The 18Z weather balloon from the University of Manitoba shows a substantial cap preventing convection over the Red River Valley. However, this cap will weaken as the day progresses and thunderstorms are still possible in southern Manitoba this evening and tonight. #mbstorm
