.Aviation... VFR conditions will prevail throughout the forecast period. Light and variable winds across all terminals overnight will increase out of the west northwest to near 10 knots by late Tuesday morning. These winds will then once again diminish on Tuesday night.

No changes needed to be made to the forecast as everything looks on track. A reinforcing cold front will move through the region by Tuesday morning. This front will not have enough moisture to work with, so it will move through dry. High pressure will build into the region behind the front during the rest of the day on Tuesday allowing for the dry conditions to continue. High temperatures on Tuesday will range from the mid 70s across the northwestern interior to around 80 across the east coast metro areas.

Short Term (Through Tuesday night)... Low clouds finally lifted out this afternoon as a storm system along eastern seaboard continues to move Ne. Jet streak just north of the area will continue to bring in occasional mid and high clouds. A cold front will sweep through the area Tuesday morning bringing in a period of cloudiness in the morning followed by clearing in the afternoon. The front may produce a few showers along the coast otherwise a mainly dry frontal passage expected. A cool area of high pressure builds into the area Tuesday night in the wake of the front bringing in cooler and drier conditions.

Long Term - Wednesday through Monday
High pressure then builds across the area behind the boundary late Wednesday and slides further into the Western Atlantic by the end of the week. This will aid in veering winds out of the northeast then east. The addition of an easterly component to the flow will modify the airmass and induce a gradual warming trend back above 80 during the day. With amplified ridging aloft, South Florida should remain dry into the first half of the weekend.

Thereafter, global models depict cyclogenesis over the Central CONUS quickly departing northeastward as a result of a progressive and amplifying upper level trough. There is fairly good agreement on the 12Z runs of the GFS and ECMWF (European Centre for Medium-Range Weather Forecasts) on a frontal passage across south Fl Sunday morning. Most of the deep moisture lifts north of the area although the front may bring isolated to scattered showers (best rain chances gulf coast) Sunday morning. Clearing with cooler and drier conditions late Sunday into early next week.

Marine... SCA (Small Craft Advisory) remains in effect through tonight. Large Ne swells will produce combined seas of 7 to 10 feet into tonight. The northeast swells will decrease on Tuesday with combined seas of 4 to 6 feet expected by Tuesday afternoon.

Beach Forecast... A High Surf Advisory remains in effect for possible breakers of 7 to 8 feet over the beaches of Palm Beach County, along with a High Risk of Rip currents. Minor coastal flooding is possible during high tide along Palm Beach...Broward...and Miami-Dade counties into early Tuesday morning.

Aviation... Prevailing VFR cigs have developed this afternoon with scattered decks around 1500-3000 ft into this evening. Mainly VFR tonight but model guidance from HRRR (High-Resolution Rapid Refresh) and NAM hinting of possible low clouds late tonight through Tuesday morning that may be just above MVFR (Marginal Visual Flight Rules) cigs. For now, used mainly just scattered cigs 3500-4000 ft due to the uncertainty. Winds will be west to northwest of around 10 kt, becoming light and variable tonight and west to northwest again on Tuesday aob 10 kt.
