Sunday 4th December 2016
This day was an interesting day, decent wind shear, moderate instability but a lack of moisture would mean storms would remain fairly isolated and high based, feeding off any mid level moisture around. Models had dew points increasing during the late afternoon and early evening, but could storms survive until better conditions arrived?
I headed out to Millmerran on the Darling Downs and watched towering cumulus explode, soon enough the first storm of the day had fired up. It was high based with some decent structure. To the north a fire was ongoing and soon became a pyrocumulus with multiple cloud to ground lightning strikes recorded out of this, amazing to watch. Early evening a stiff north easterly breeze had moved across the region bringing in a high moisture content, and soon after a large clusters of cumulus towers developed from Dalby back east towards the Toowoomba region. Not long after these exploded into cloud to ground lightning machines!! Cg's rained down every couple of seconds from close range for around and hour, the constant booming from the thunder was tremendous. At around 9pm the storms had moved off to the north in a roadless area and it was time to end the chase and head on home. Fun day indeed.
