I think today looks more complicated than it may otherwise seem.

It still looks like the drier westerly flow will invade most heights of the atmosphere with just some marginal moisture in the midlevels and near the coastal fringe with the afternoon seabreeze trying to push in, as well as a midlevel inversion.
In fact, the only favourable things I can see which have the potential to overcome these is 1) the majority of models producing at least a bit of precip and lightning, 2) the cold air aloft and 3) the sunny morning skies allowing for good heating.

Any convection would have to overcome the midlevel inversion and marginal moisture first to grow tall enough for any extensive thunderstorm activity (including any severe ones) to occur.... if they can't, a lot of them would just stay as showers.

It's hard to beat the more reliable models these days though so will be interesting to see how localised or extensive any activity will be.
