| On the 27 August 2009 there were numerous thunderstorms (Which were not forecast to occur) popping up in the Gauteng area, CAPE values were around 1000 J/kg which would allow for convective storms to form. While surface dew points remained lower than that usually expected with thunderstorms- moist air moving in from the west at mid-levels of the atmosphere allowed for enough instability to create storms. According to reports the thunderstorms were accompanied by frequent lighting as well as strong winds. We should be seeing more thunderstorms up country as the transition into the Spring season begins. |
