It's ridiculous and VERY misleading for accuweather to say that a surface front will affect the motion of a freakin' tropical storm/disturbance/low. I can't believe they are getting away with that image. ARGGH!!!
As most of us in here probably know by now, these are deep systems that are controlled by deep layers of background flow. In case anyone didn't notice (Accuweather...ahem), the trough in the west is progressing east and digging, not filling!

This means that, as every model I've seen this morning so far shows, this storm will get pulled into LA, then north along the east side of the soon-to-be central North American trough. Does anyone remember the case last week where the 00Z Gem amplified the storm once it got over land (by baroclinic processes)? Well, most models are showing this now to some degree.

Check out the ECMWF, GEM, UKMET and GFS.
As the TD/TS comes northeast, I believe it will be caught by the trough in the US, and that it will transition into a deepening extratropical low across the TN/OH Valley and/or Lakes. This whole process will be followed by a MAJOR early-season trough in the Central/Eastern US. Any indication of a low along the eastern seaboard will be new development, as I see it now (and probably not tropical).
Also of note is the storm that will affect Bermuda and the Canadian Maritimes. This looks to be a big ticket storm as well.
