A light northerly flow will continue this afternoon as a weak area of low pressure just off the coast continues to move east. A light to moderate northwest flow is expected late tonight through Saturday afternoon as a surface ridge of high pressure to the west shifts east.

Short Term.

This Afternoon through Saturday night :

Scattered showers and a few thunderstorms will continue throughout the remainder of this afternoon into the evening hours as a cold front advances towards the region. A few mid-level impulses also march through the region this afternoon and overnight further aiding the development for activity. Best coverage of showers/storms is forecast over the Atlantic and across the eastern half of the Peninsula, particularly Palm Beach county with the southwest steering flow this afternoon. A few storms out over the Atlantic could be fairly strong this afternoon and evening, but southwesterly steering flow should keep them offshore. Morning E winds finally veered from the S/SW this afternoon as an area of low pressure pushes northeastward across the peninsula and treks along the SE CONUS coast. The aforementioned cold front associated with this low will push through South Florida tomorrow with showers, and perhaps a thunderstorm or two. Forecast soundings do have relatively decent CAPE and SRH values across the local waters tomorrow morning so wouldn't be surprised if brief areas of rotation were seen. Otherwise, despite this being a rather impressive negatively tilted trough, most upper-level support/dynamics and jet activity stays well to the north of the area. Northwesterly to northerly winds are expected in the wake of the front with slightly cooler, but not too much, and drier air filtering in over the area. Low temperatures Saturday night are forecast to drop into the low 50s west of the Lake to near 60 along the east coast.

Long Term.

Sunday through Monday .

High pressure will then build in over the Southeast CONUS, bringing a brief shot of cooler, drier air to South Florida. As the high continues to slide into the Western Atlantic, surface winds will quickly veer out of the east on Sunday and then southeast by Monday evening. This will help modify the airmass and initiate a gradual increase in moisture through the atmospheric column.

As mentioned, the cool down will be short-lived with Sunday morning temperatures in the 50s across much of South Florida and low 60s along the east coast metro, climbing Monday night into the upper 50s to low 60s with the east coast metro in the mid to upper 60s. Daytime temperatures will also be slightly cooler on Sunday in the upper 70s across the area and low 80s along the southwestern interior. Then in the low to mid 80s on Monday afternoon.

Tuesday through Friday .

The mention of rain returns to the forecast on Tuesday as a deepening low over the Northeast CONUS pushes off the eastern seaboard, dragging the next frontal boundary down the peninsula towards South Florida. While global models continue to differ in the front's intensity, convective coverage should begin to increase Tuesday ahead of the boundary and continue through the day on Wednesday. Activity should consist of mostly scattered showers with much of the upper level support for deeper convection remaining well to the north. However, cannot rule out a few rumbles of thunders.

Behind the boundary, coverage of showers will refocus across the Atlantic waters with drier conditions elsewhere. Also in the wake of the front, cold air will advect into South Florida with overnight lows progged to dip into the upper 40s to low 50s across the interior and Lake Okeechobee region and upper 50s to low 60s along the east coast on Thursday and Friday mornings. Daytime temperatures will range from the low to mid 70s. Given the finer details have yet to be resolved between individual global models and their solutions, have gone with the blended approach for PoPs and temperatures and will continue to monitor as we get closer in time.

Marine.

Hazardous marine conditions continue for the Atlantic waters through Saturday with seas remaining elevated in the Gulf Stream. Winds may diminish overnight but are forecast to increase again Saturday afternoon to advisory levels over the Palm Beach waters. Passing showers and a few thunderstorms will be possible across all waters today and tonight as a stalled front over the Lake Region pushes northward. A cold front will push through the area tomorrow, with northwesterly winds in its wake. Hazardous boating conditions are expected to improve in the wake of this front. However, another stronger front will push through around middle of next week and may create hazardous marine conditions at that time.

Aviation.

Generally VFR conditions are expected to prevail into this afternoon, but some shower activity at times could cause some MVFR conditions. Most models keep the heavier SHRA and TS offshore in the Atlantic waters, but again, east coast sites may see a passing shower through 00Z this evening with KPBI having the chance through 04Z. If TS were able to develop along the coast, KPBI has the greatest potential, but due to low confidence, omitted from TAFs at this time. Winds gradually become southwesterly through the period as a cold front approaches the region with breezy SW to W winds tomorrow. Chances for SHRA exist tomorrow morning and early afternoon, but again, low confidence on coverage and timing is causing omission from TAFs.

Beach Forecast.

A high risk of rip currents is forecast for the Atlantic beaches through at least Saturday evening as lingering swell continues to affect the coast. Rough surf will also be possible for the Palm Beaches. Rip currents should improve some this weekend before elevating again early next week with breezy east flow.
