 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.
