\textbf{Methodology}  At Australian Capital City sites, all soundings between 2008-2015 were extracted from the BoM. Thunderstorm soundings were identified using GPATS lightning strike data. A sounding was flagged as a thunderstorm sounding if, (a) 1 or more strikes occurred within a 50km box centered about the sounding site, and (b) within +-1hour from the sounding time. A total of 316 thunderstorm soundings were identified using this method.  For each thunderstorm sounding the following was calculated:  \begin{itemize}  \item Theta Surface (K) 

\item TD MUCAPE (C)  \end{itemize}  \textbfUsing \textbf{Using  Present Weather Reports of Thunderstorms?} \begin{itemize}  \item Using Present Weather Reports=thunderstorms +-1 hour from sounding time, identified only 2 soundings (Melbourne 2013-03-16 1200UTC, 2013-05-31 1236UTC).  \item Analysing present weather data for all years at Melbourne Airport with the same time criteria gives \textbf{9} between 23-00UTC, \textbf{41} between 11-12UTC.
