Severe storms Armidale to Nowendoc - Northern Tablelands: Thursday 27th October 2005
Report compiled by Jimmy Deguara and Michael Bath

Conditions according to models on this day were favourable for severe storms including supercells - mainly HP supercells. Air was already unstable in the region with rich dew points invading the area and considerable heating. The only concern were the westerlies! Concern - it was to deplete any chance of any storms let alone severe weather in region west of Tamworth.

In Tamworth, and a strong very crisp updraft exploded to the north - the northwest end of a set of rain free based towers. The storms were beginning to tap the moisture - so we thought! After a long meander, the storm never seemed to attain very severe characteristics despite showing some signs of strength.

It seemed better storms were in the region to the south of Walcha - the overshoot indicative of the powerful updrafts. But nothing was to prepare us for we were to experience. As we neared Top Dale, moisture was clearly invading the area in a line of convergence. One particular cluster of cumulus began to accelerate upwards - good pose for a few photographs. But as we travelled further southeast, David pointed out in excitement a powerful bulge of an updraft. We pulled over immediately and watched almost in disbelief that the storm had developed such a structure in such a short time span! The camera worked overtime as new features and detail evolved - the video camera quietly capturing timelapse.
