.Aviation... VFR expected to prevail at all terminals during the next 24 hours, except APF where some brief IFR cigs may still happen through around 14Z. For the rest of today, a few showers may develop in the vicinity of the Atlantic terminals this afternoon, but any MVFR (Marginal Visual Flight Rules) conditions should be very brief. Winds turn northerly with gusts to 25kt at times after 18Z, then subside this evening.

Long Term... Thursday through Sunday... The slight cool down behind the frontal boundary will be short- lived as winds quickly veer out the east and moderate temperatures back up a few degrees. However, this warming trend will also be brief, as a well defined southern stream trough on water vapor imagery gains eastward momentum and traverses across the northern Gulf of Mexico. This shortwave will phase with an amplifying northern stream trough and develop a surface low across the FL/GA bend and adjacent Atlantic waters of Friday. Global models have come into better agreement, pushing the deepening cyclone off towards the northeast and dragging the next cold front across the region. Southerly flow will increase ahead of the boundary, allowing for moisture advection into South Florida. With PWATs (Precipitable Waters) briefly rebounding to near 2.0 inches, rain chances will increase Friday into Saturday. While most of the activity will likely be scattered showers, a vorticity maxima and a jet streak aloft could provide enough instability to allow for elevated convection and a few thunderstorms to develop.

Northwesterly to northerly flow behind to boundary will allow cooler and drier conditions to return. Rain chances will remain mostly across the Atlantic waters by the end of the weekend while also gradually diminishing as the weekend progress. Daytime temperatures should range in the 70s to near 80. Overnight, temperatures will dip into the 60s, with some areas over the northwestern interior dropping into the mid to upper 50s.

Monday and Tuesday... The upper level pattern should remain highly amplified early next week as we have reached a more baroclinically unstable time of year. The forecast pattern will consist of troughing over the southeast CONUS, another attendant low reflected at the surface, and a frontal boundary draped somewhere in the vicinity to South Florida. While it's no surprise models differ in the details for the tail end of the period, model time heigheights depict increased moisture through the column and favorable lift aloft to steadily increase shower chances during the week. Temperatures should also remain near to below average for the start of the the week, followed by a gradual warming trend possible thereafter.

Marine... Northwesterly to northerly winds will continue to establish in the wake of a cold front passage. Winds and seas are expected to increase today, especially over the Atlantic and the offshore Gulf waters. Small Craft operators should exercise caution, and a Small Craft Advisory will be in effect for the Atlantic coastal waters starting late this morning.

Beach Forecast... The High Risk of rip currents continues in effect for all Palm Beach county beaches until this evening, while a moderate risk also remains for the Miami-Dade and Broward County beaches.

Minor coastal flooding is still possible today, especially around the Atlantic Intracoastal Waterway during high tides. Minor flooding of these areas will likely continue into at least this afternoon, and a Coastal Flood Statement remains in effect for the Atlantic coast.
