Remember the day of the Brum tornado quite well, although positioned app 25miles NW, weather was quite non-descript, breezy, only bright intervals in fact quite cool damp feeling - more sunshine suddenly appeared then humidity seemed to shoot through the roof! Go into overdrive, a massive dark base just grew from nowhere, distant thunder and lightning eventually prevailed..at one point the wind just went manic, just knew this was letting off some pretty serious weather somewhere..glanced at the exact time, rest as they say was history!
Was not surprised to hear the first reports coming in..
