MSBWX National Severe Weather Observations:   Mammatus Clouds Observed: Gauteng  20 November 2014 





Mammatus, also known as mammatocumulus (meaning "mammary cloud" or "breast cloud"), is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud. Mammatus are most often associated with the anvil cloud and also severe thunderstorms. When occurring in cumulonimbus, mammatus are often indicative of a particularly strong storm or maybe even a tornadic storm. True to their ominous appearance, mammatus clouds are often harbingers of a coming storm or other extreme weather system. Typically composed primarily of ice, they can extend for hundreds of miles in each direction and individual formations can remain visibly static for ten to fifteen minutes at a time. While they may appear foreboding they are merely the messengers - appearing around, before or even after severe weather.  Thankfully no report of any severe weather was received yesterday.


MSBWX General Weather Observations: Cool, warm to hot conditions expected today over parts of SA.   Thunderstorms can be expected in parts of  Gauteng, Mpumalanga, Limpopo, North West, Free State, and Kwazulu Natal. Drizzle can be expected in the eastern parts of the Eastern Cape this morning.
