I would expect a continued decrease in mid-level shear over the next 24 hours. The upper low to the west appears to be filling as it moves inland over the Yucatan Peninsula. It has been providing a good low-level environment for our central Caribbean system. There is a good source for low-level convergence and abundant mid-level diffluence. Look at the latest shortwave imagery. The current trends indicate increasing instability (i.e. favorable convective parameters) and a conducive overnight diurnal maximum. I definitely think we could eventually witness our next INVEST, IMO. The slow motion could help organization, too.
I think we should wait for a defined LLC before declaring a possible path. Currently, I do not see any signs of a low-level circulation, but I do think we won't wait very long for a sfc low formation. Note the persistent convective "pulse" SSE of Kingston, Jamaica. Low-level vorticity is greatest in that vicinity - if a LLC will form, I think this area should be monitored (near 16.4N and 76.9W). I think we should watch land and buoy obs near Jamaica - I think we could observe the beginning of a slow LLC formation within the next 24 to 46 hours. If convection steadily increases, it could occur sooner than we think - watch for NNE and WSW sfc winds. I do agree with wxman57 - there are no substantial signs of a sfc low, but I think we could observe the key early stages of a critical sfc low formation within the next few days.
What do you think?
I tried to check the buoys near Jamaica. There are on a waiting list for repairs. Nearest working buoy is West of Caymans.
