Issued at 1013 AM EDT Fri May 24 2024 A beautiful and sunny start to the day across the Florida Keys this morning. We have some showers across the outer Gulf waters where east-southeast winds converged on northeast to east winds coming off the mainland last night. These showers are gradually waning and there are no additional showers being detected across our CWA. Light winds and clear skies overnight led to some impressive radiational cooling across the interior of our larger keys. In fact, the RAWS at the north end of Big Pine Key registered a low temp of 72 degrees around 6 AM, which was 10 degrees cooler than either Marathon or Key West! Looking at satellite derived precipitable waters, we can see that drier air is pivoting in from the east. This is evident on this morning`s sounding which shows a pronounced dry layer punching in around 700 mb. The PWat measured this morning was nearly a half inch lower than this time yesterday. As such rain chances are near nil for today and will remain as such. Daytime temperatures will once again reach to near 90 and dew points look to hold in the lower 70s. This combination will keep heat index below heat advisory thresholds. Lastly, weak surface high pressure will keep our winds light and possibly variable winds. && .MARINE... Issued at 1013 AM EDT Fri May 24 2024 Light to gentle east to southeast breezes will continue through the end of the week as high pressure will remain in place. During the later half of Sunday, breezes will clock to a southeasterly to south direction and modestly freshen as the high pressure shifts its position. && .AVIATION...
