They are forecasting even higher temperature today, and that does look likely. There is no apparent high cloud cover and very little Caribbean cloud cover, what cloud there is, appears to be moving or more likely clearing to the north. And, of course, the sun is getting higher in the sky each day. There is presently, light surface wind, but this will pick up as it follows the sun.
It does look as if today could well be the warmest day of the year and close to the 07Apr14 of 99°F and 28Apr15 of 102°F The good news about those two is that they were just that hot for one day, 2015 then resulted in two days of rain, but not 2014.
