Quick check of the GFS and Canadian models.

GFS and Canadian take the thunderstorms currently in the Jamaica area toward the Yucatan Peninsula and the BOC. Little or no development noted... at this time.

Area near the Turks and Caicos Islands. The Canadian model develops this slowly over the next 90 hours,( from 8 PM EDT last night), slowly spins it up just off of the Florida EAST Coast and takes it up the Atlantic Coast toward Cape Cod,MA.
The Canadian has been consistent with this low level system for about 4 days now. Canadian has been known to create false systems in the past.

These comments are based off of model runs, a probably should be in the Forecast Lounge. But they tie in with the above satellite photos.
