The structure of Tomas looks really strange this afternoon on the sat pics. Seems to be interacting with the moist area that was West of it yesterday while the convection that was East of the center has caused a gust front moving from west to east, east of the system. The cold front and long wave trough is beginning to move southeastward across the GoM and does look like it will be picking Tomas up on late Wed or Thursday, unless Tomas remains far enough south to avoid that. That would imply that Tomas would continue to the west and impact Central America to me.
