Issued at 1030 PM EDT Wed May 8 2024 Currently - A surface through lower Atlantic ridge stretches westward across the Florida Peninsula and into the Gulf of Mexico. This is generating gentle to moderate east to southeasterly breezes across the Keys. Fairly sharp mid and upper level ridging is now aligned across our area and brings with it higher heights and decreasing moisture. This evenings sounding indicated a couple of prominent inversion layers with the most important one based around 900 mb. Precipitable water has fallen to a bit more than one inch despite surface dew points remaining in the lower 70s. Overall, conditions are unfavorable for shower formation and the only activity currently seen on local radars reside along Cuba`s southern coast. Short Term Update - Robust ridging across Florida is expected to settle slightly southward through the overnight period. This along with the usual diurnal patterns should result in a slight increase in east to southeasterly breezes over the next few hours, but then lead to a moderate amount of relaxing out of the southeast. Healthy ridging through the mid and upper levels will continue to dominate our area. This will assist in maintaining an overall inhospitable environment for showers. As a result, rain chances will remain out of the forecast. Summer is definitely well on the way as overnight lows will struggle to slip below 80 with dew points holding in the lower to mid 70s. && .MARINE...
