(Today through Friday) Issued at 103 AM EDT Thu May 30 2024 A subtle upper troughing pattern will remain present across SE CONUS (including South Florida), with a few southern stream impulses drifting equatorward towards our region. The most noteworthy change compared to prior days will be a distinct change in the low-level flow regime, as east-northeasterly winds are expected to prevail across the CWFA. As a result, low-level moisture convergence maxima will generally become most prevalent across portions of the interior and southwest Florida - where the greatest convective coverage is expected tomorrow afternoon. Certainly cannot rule out a few strong to even marginally severe thunderstorms will moisture convergence becomes best juxtaposed with favorable mesoscale ingredients such as steepened lapse rates and enhanced ML CAPE, particularly from the early afternoon through late evening hours. Friday will feature the gradual building of upper level geopotential heights, as well as a general weakening in the upper flow regime with shortwave departing eastward into the western Atlantic waters. This will cause a subtle backing of flow near the surface, which may shift the highest storm coverage a further westward into portions of Collier County and the western interior region. Expect weaker storms on average, given the less favorable synoptic regime. Strong wind gusts, frequent lightning, and localized flooding remain the primary impacts to monitor. Afternoon maximum temperatures through Friday generally remain in the upper 80s to low 90s, with the highest temperatures being realized across western portions of the region. Most populated regions across South Florida will remain well below heat advisory criteria, with apparent temperatures generally not exceeding 100-102 degrees.

(Friday night through Wednesday) Issued at 103 AM EDT Thu May 30 2024 A welcomed change in the weather pattern is to be expected across much of South Florida this upcoming weekend, owing to a backdoor cold front across the western Atlantic waters. This will maintain the prevalence of east-northeasterly winds, which will result in a milder breeze coming in from the Atlantic waters across eastern portions of our CWFA. Expect a few quick-moving low-topped showers across the east coast at times, with the bulk of convection spawning yet again over the interior and southwestern portions of the region. A generally quiescent synoptic regime should limit thunderstorm intensity, however cannot rule out a few strong pulse storms that take advantage of high instability across the interior region. Towards the beginning to middle of next week, winds will gradually veer out of the east, resulting in a slight uptick in temperatures across the region. Expect a few showers and possibly thunderstorms in the morning hours across the east coast, with a gradual westward drift towards the interior again. A much needed reprieve from the oppressive temperatures can be expected through the weekend and into early next week across much of South Florida. Afternoon high temperatures in the mid to upper 80s can be expected along the east coast. Dewpoints will drop to a more manageable 65-68 degrees, allowing for lower apparent temperatures in the upper 80s to low 90s. A gradual warming will take place towards early to middle portions of next week.

(06Z TAFS) Issued at 103 AM EDT Thu May 30 2024 VFR conditions are expected to prevail through the TAF cycle. Winds become ENE around 10 kt by afternoon for eastern sites, and most convection generally expected over interior and SW FL (possibly near APF). SW flow expected near APF in conjunction with Gulf sea breeze.

Issued at 103 AM EDT Thu May 30 2024 Generally benign boating conditions will continue through the end of the week. By this weekend however, wave heights will increase over the Atlantic waters. Waves may be as high as 5 to 6 feet in the presence of a backdoor cold front. Winds may increase out of the east-northeast up to around 20 kt this weekend as well, which may prompt a Small Craft Advisory. Aside from this, daily showers and thunderstorms could develop possibly resulting locally elevated winds and seas periodically.

Issued at 103 AM EDT Thu May 30 2024 Enhanced easterly flow in the presence of a departing front will increase the risk for rip currents this weekend across the Atlantic beaches. As a result, a high risk for rip current could develop across the Atlantic beaches this weekend.
