Yes, I was just looking at the 12Z UKMET ... it stalls the system NE of the Bahamas and intensifies it there. At the end of the forecast period, it looks like the ridge is strengthening again, which suggests it would turn it towards central or northern Florida.
The Canadian is a little quicker and further south with it out to 72 hours - with a much stronger ridge which suggests it wouls steer it across Florida into the Gulf.
GFS and GFDL are a little south of the UKMET, and not as bullish on development.

MLB NWS ...
for what it's worth, here's what they had to say:
I think the key here is what exactly develops. The globals don't show much of a system ... more of a strong wave until late in the period. Right now, the wave appears to be consolidating, but there still is obviously no LLC with convection centered around it. Once we have a system, we can decide who's going to be impacted by it. Right now, we're just looking at more rain here in the FL peninsula, so I wouldn't worry too much just yet.
MON-THU...BERMUDA RIDGE REBUILDS ALONG 30-32N WITH DRYING INDICATED
BY GFS DUE TO BACKING FLOW. SUBSIDENT REGION ASCD WITH APPROACHING
SYSTEM FROM THE BAHAMAS IS ALSO SHOWN DRYING OUT AIRMASS. WILL HAVE
TO CLOSELY MONITOR SYSTEM FOR POTENTIAL TC FORMATION E-SE OF THE
BAHAMAS. LATEST RUN OF GFS INDICATES REDEVELOPMENT OF RIDGE ACROSS N
FL FROM TUE ONWARD WHICH WL KEEP WAVE OR CYCLONE ON GENERAL WNW
HEADING THRU THE MIDDLE OF WEEK...WHICH IS WHAT THE ECM HAS BEEN
ADVERTISING ALL ALONG. STAY TUNED.
