Area Forecast Discussion . UPDATED National Weather Service Miami FL 816 PM EST Mon Dec 9 2019

Update. High pressure over the Western Atlantic waters will continue to move slowly east further into the Atlantic waters. This will keep an southeast wind flow over South Florida tonight bringing in some low level moisture to the area. There could be a few showers over the east coast metro areas tonight and the forecast shows this. Therefore, no changes are planned at this time to the forecast.

Aviation. The winds will remain southeasterly tonight over the TAF sites. There could be a few showers affecting the east coast TAF sites, but the coverage will be few and far between to put in the TAF sites. The ceiling and vis will also remain in VFR conditions tonight.

Prev Discussion. /issued 225 PM EST Mon Dec 9 2019/

Short Term .

A ridge of high pressure will continue to move eastward over the Atlantic for tonight and Tuesday. Patchy fog could develop late tonight across the interior and west coast sections. Any fog that does develop will begin to dissipate shortly after sunrise. There will also be enough low level moisture to support a slight chance of showers tonight across the Atlantic waters and the east coast metro areas.

On Tuesday, a cold front stretching across the Mid Atlantic States into the southeastern portion of the country will continue to move southeastward. South Florida will remain in the warm sector which will allow for warm temperatures and humid conditions during the day as the low level moisture increases. High temperatures during the afternoon will range from the lower 80s across the east coast metro areas to the upper 80s across the interior sections.

Long Term . The afore mentioned cold front should stall over North or Central Florida by Tuesday night. This will leave a baroclinic zone over that area for a few days. It will also keep the area in the warm sector with plenty of moisture to allow for at least some shower activity for the middle of the week. If it is able to warm enough in the interior, the sea breezes may be able to initiate, and could potentially bring some additional instability to the area, which could allow for for a few thunderstorms, especially in the interior and Lake region.

By late Thursday, into Thursday night, a 500mb short wave trough will move across Texas and begin to interact with the baroclinic zone. this will cause some cyclogenesis over the northern Gulf, and bring some additional instability to the area for the end of the week. As it does, there is a weak sub tropical jet at 250mb that is moving across the Gulf, and joins with the polar jet by Friday morning. This jet, right around 90kts, should pass over the Florida peninsula on Friday, which should aid in any convective development on Friday, giving rise to a better potential for thunderstorms Friday afternoon through early Saturday morning. The front should quickly move through on Saturday, probably in the morning, with the best dynamics north of the CWA, lessening the chances for thunderstorms over South Florida on Saturday. Behind the front, the air mass will not be significantly cooler, maybe bringing highs down a degree or two on Sunday, but it should be much drier, with dew points dropping back into the low 60s.

Marine .

Southeasterly flow will continue across the Atlantic and Gulf coastal waters on Tuesday as high pressure continues to move eastward over the Atlantic. A cold front will begin to move towards the area by the middle of the week. Marine conditions will deteriorate during the second half of the week as the winds, waves and shower activity increases. A northerly swell will also impact the Atlantic waters during the Thursday and Friday time frame as well.

Aviation .

VFR conditions will prevail throughout the forecast period. Southeast winds will continue at around 10 knots for the rest of this afternoon and into this evening. A shower or two cannot be ruled out later this afternoon through tonight along the east coast terminals, but the confidence was too low to mention in TAFS. At KAPF, winds will shift to the south southwest this afternoon as the Gulf coast sea breeze moves inland.

Beach Forecast .

A moderate risk of rip currents will continue for the Palm Beach County beaches as the southeasterly flow continues to increase during the day on Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
