.Short Term (Wednesday and Thursday)... Surface analysis reveals high pressure extending across the FL peninsula, maintaining moderate easterly flow in the boundary layer. Aloft, stout ridging remains anchored, enhancing subsidence in the mid levels. This synoptic setup should allow for plentiful sunshine to keep warm temperatures around each afternoon, while drier air quells convection across South Florida. Although, can't rule out an isolated sprinkle or two as onshore flow should support enough moisture in the boundary layer. Any shower that is capable of developing, however, should be short-lived and quick- moving.

On Thursday, winds gradually become more southerly through the day in response to a deepening low over the Southeastern CONUS. While the overall pattern should remain rather benign, this added southerly component could aid pockets of additional moisture into the area, and thus, the potential for a bit more coverage of showers over the interior and Lake Okeechobee region in the afternoon and early evening hours.

Temperatures for the short term are forecast to be slightly warmer than normals, with most areas experiencing highs in the mid/upper 80s, with the western counties and Gulf coast potentially climbing into the lower 90s.

.Long Term... Thursday night through Tuesday night... A 500mb trough and an associated surface low pressure system should be exiting the southeast United States by Thursday evening. As they do, the surface low show drag a weak cold front through Central, then South Florida on Friday and Saturday. This will keep at least a slight chance of showers and thunderstorms int eh forecast.

The front is fairly weak, and is slow moving, but both the GFS and the ECMWF (European Centre for Medium-Range Weather Forecasts) both agree the front should push through the area by Sunday morning. however, both show there may some showers that linger over the far southern tip of the Florida peninsula through the end of the weekend. By Monday, surface high pressure should build to the north, and advect a drier air mass into the area for at least the beginning of next week, with dew points in the upper 60s by Monday afternoon and in the mid 60s by Tuesday afternoon.

Marine
High pressure across the local waters will keep moderately east to southeasterly flow today. The NE swell affecting the nearshore/offshore Palm Beach waters will gradually subside, and should be non-existent by mid/late-week. Winds gradually veer out of the south to southwest tomorrow and Friday ahead of an approaching cold front. Over the weekend, flow further veers out of the north to northeast behind the front, increasing seas/swell across the Atlantic early next week.

High pressure across the region will keep generally dry, benign weather and VFR conditions across all terminals through the taf period. Brief bouts of MVFR (Marginal Visual Flight Rules) CIGs may continue over the next few hours, albeit, coverage should remain predominately FEW/SCT. Breezy E flow of 10 to 15 knots expected through the cycle, with occasionally higher gusts possible after 15z.

.Beach Forecast... A high risk of rip currents remains in effect for the Atlantic beaches through Thursday evening due to the moderate onshore (easterly) wind and NE swell. The risk should diminish towards the end the week into the weekend.

NOAA Miami FL Office: Watches - Warnings - Advisories
FL...High Rip Current Risk through Thursday evening for FLZ168-172- 173.

AM...None. GM...None.
