New LONG TERM


SHORT TERM
(Rest of today through Monday)
Issued at 1224 PM EST Sun Dec 10 2023

After a very pleasant start to the day under mostly clear skies and southerly winds, conditions will start becoming unsettled this evening as a strong mid level trough progresses across the eastern US, pushing a cold front across the SE US and the Florida peninsula. PWATs are forecast to gradually increase up to the 1.5 to 1.7 inch range as the front nears our area, which will support enhanced convection over the coastal waters first, and then spreading over land. Latest POPs remain in the 40 to 60 percent chance, with a chance of thunderstorms late this evening and through the night. Can’t rule out a few stronger cells with gusty to damaging winds and frequent lightning, especially along the Atlantic coastline where coastal convergence may promote deeper convection.

The front will clear our area by early Monday morning and an area of high pressure will start to build in from the SE US. This should usher a brief period of dry, quiet weather as cooler, drier air advects over our area. It will also help keep daytime temps on Monday in the 70s and overnight temperatures in the mid 50s (over the interior) and mid 60s (along the East Coast). Winds behind the front will remain breezy, with northerly to northeasterly winds 15-20 kts.

LONG TERM
(Monday night through Saturday)
Issued at 343 PM EST Sun Dec 10 2023

Models remain persistent in showing a decaying boundary remaining nearly stationary around the Florida Keys through mid week.
Pressure gradients between the boundary and high pressure expanding across the region should become tighter, resulting in periods of breezy and gusty northeasterly winds, especially during the afternoon hours across much of South FL.

Ensemble solutions show fair agreement in depicting another surge of moisture across SoFlo as the aforementioned boundary retrogrades back into the area. A stratiform deck should accompany the returning boundary, with POPs jumping back into the 50, 60, or even 70 percent range, especially around the east coast, on Thursday. Model PWATs still show potential for up to 2 inches Thursday afternoon, and even isolated max QPF values of up to 4 inches. However, it is too early to embrace any particular solution. Thus, the forecast philosophy will remain on the conservative side in terms of QPF, and continue to adjust accordingly as new guidance becomes available.

AVIATION
(18Z TAFS)
Issued at 1224 PM EST Sun Dec 10 2023

Generally VFR conditions and gusty S-SE flow through this afternoon before a front begins to move through the area. Shower and thunderstorm chances increase in the late afternoon and evening with the potential for bouts of sub-VFR at terminals directly impacted by convection. Short-fused AMDs for sub-MVFR cigs/vsbys may be needed. The front should be past the terminals by 09Z, with dry conditions and gusty northerly flow following behind it.

MARINE
Issued at 1224 PM EST Sun Dec 10 2023

Breezy southerly to southeasterly winds at 15-20 kts will prevail today ahead of an approaching cold front. Scattered showers and thunderstorms will be possible this evening and overnight as the front pushes through.

Winds and seas will increase behind the front starting tonight and persisting through the end of the week, resulting in hazardous marine conditions across all local waters. Winds are forecast to increase up to 20-25 kts with gusts up to 30-35 kts by the middle of the week, while seas could build up to 6-11 feet across the Atlantic waters. With this in mind, a Small Craft Advisory will be in effect for the Gulf Waters starting 10PM tonight through at least Monday evening. For the local Atlantic waters, a Small Craft Advisory will also go into effect at 4AM tomorrow morning lasting through at least Tuesday evening.

BEACHES
Issued at 1224 PM EST Sun Dec 10 2023

A Rip Current Statement remains in effect through this evening along the Atlantic Coast beaches. Gusty northerly winds developing behind the cold front moving through tonight will lead to hazardous beach conditions along the Atlantic Coast for much of the upcoming week with high rip current risks and high surf. Along the Gulf beaches, the rip current risk will be elevated on Monday.
