The previous cold front or bubble of cool air from the US is now out over the Atlantic ans pushing against the Caribbean easterly winds, producing cloud in the Caribbean winds over the last few days, and likely to continue for several more days, it is this causing the cloud and rain. There is some cloud conflict with some high level winds.
Looks like today will be a mixture of mainly cloud with a little sun and a possibility of rain showers.
