That is a possible scenario, but not a likely one at this point....the GFDL model is hinting at that, but I believe it to be too far south...if the ridge is much stronger than forecast, then that is a possibility..but at this point not a likelyhood.

The front is a result of other processes that are occuring in the atmosphere, and those are being taken into account..so the effect of the front is really the effects of the entire pattern...you can't really single it out like that too much..

I'm not exactly sure of what you mean in your last question...you mean atmospheric moisture??
