EWP: UW-CTC captures sea breeze convection

Ahead of the frontally forced convection over the southeastern US, the sea breeze along coastal South Carolina provided a trigger for thunderstorm development late this morning.  Figures 1 and 2 below show the UW-CTC algorithm capturing these newly developing thunderstorms at 1632 and 1645 UTC 09 May 2012, respectively.  These storms went on to produce 50-60 dBZ composite reflectivity (not shown because radar data was not available at those times).   The figures below show GOES IR-window brightness temperatures (top left), GOES visible reflectance and NLDN lightning detection (top right), UW-CTC rates (bottom left), and UW-CTC ice mask (bottom right).
