Convective Discussion
There is a low probability that severe or near severe thunderstorms could develop today over the gulf waters and Northumberland Straight. The dynamics are good with plenty of deep shear and weak convergence along a surface trough. It may be a struggle to break through a stable layer above 700mb until later today when it weakens however daytime heating will also be weakening. For now no severe thunderstorm alerts are expected however should longer lived cells develop they may be issued. The warmer waters this time of year may also help to feed the thunderstorms and should they develop could pose a risk to marine waters.
