Synopsis.. Increasing northeast winds will impact the gulf waters overnight, as a weak cold front moves into south florida and becomes diffuse. Conditions will deteriorate across the atlantic waters on Thursday as northeasterly swell from a deepening low off the u.s. East coast arrives into our local waters. This swell will cause wave heights to increase to between 6 and 9 feet, with the highest seas in the gulf stream. The impact of this swell will be short-lived, with seas subsiding on Friday, and benign marine conditions expected for the weekend into early next week.
Gulf stream hazards..Increasing waves and swell Thursday and Friday. The approximate location of the west wall of the gulf stream as of dec 10, 2019 at 1200 utc... 19 nautical miles east northeast of fowey rocks. 20 nautical miles east northeast of port everglades. 15 nautical miles east of lake worth. 19 nautical miles east southeast of jupiter inlet.

Area Forecast Discussion National Weather Service Miami FL 108 AM EST Thu Dec 12 2019

Aviation. Although VFR should prevail for the most part during the next 24 hours, scattered to numerous showers will develop today, especially around PBI, FXE and FLL due to the influence of a lingering frontal boundary. Not confident enough to include thunder attm, but will keep carrying reduced vis/cigs with heavy showers in tempos or prob30 groups for today. Winds remain between east-northeast and southeast near 7-10 knots.

Prev Discussion. /issued 734 PM EST Wed Dec 11 2019/

Update . A cold front over Central Florida will continue to move slowly southward tonight into the Lake Okeechobee region. This will allow for the wind flow over South Florida to be easterly with speeds of 10 to 15 knots over most of the local waters, except over the Gulf waters where it will be 15 to 20 knots with even around 20 knots over the offshore Gulf waters. The winds over the mainland areas should decrease to around 5 knots or less late tonight. This will allow for showers and even a few thunderstorms to develop late this evening into the overnight hours over the metro areas Palm Beach and possible northern areas of Broward Counties. Rest of South Florida should see mostly dry conditions after midnight, as the showers and thunderstorms over the interior and west coast metro areas dissipate this evening.

The PWAT values this evening from the MIA sounding is around 2 inches which is near the maximum values for this time of year. Therefore, any showers and thunderstorms that do develop over the metro areas of Palm Beach and Northern Broward Counties could see some heavy rainfall late this evening into the overnight hours.

Rest of the forecast looks good at this time and no other changes are planned.

Prev Discussion . /issued Issued by National Weather Service Key West FL/

Short Term (Tonight through Friday Night) . Scattered to numerous showers are present across parts of South Florida as of mid afternoon, with the greatest convective coverage extending along an axis from northern Palm Beach County SSW across the interior and Mainland Monroe. Occasional lightning strikes have been detected. Slow movement of the activity is producing some locally heavy downpours, with recent radar estimates approaching two inches during the last hour in southern Broward near Southwest Ranches. Temperatures have risen into the lower to mid 80s, except for 70s in rain cooled areas, with dewpoints mostly in the lower 70s.

Surface analysis depicts a cold front across central Florida, extending from Cape Canaveral to Tampa Bay. Aloft, water vapor imagery shows broad troughing over the eastern CONUS, with a shortwave advancing eastward across eastern Louisiana. MIMIC-TPW imagery shows an axis of enhanced moisture extending from the SW Atlantic across South Florida and into the Keys. The 12Z Miami sounding reflected the enhanced moisture in place, with a couple of high inversions between 10K and 13K feet, and ample moisture beneath the inversion yielding a PW of 1.63 inches, which is near the 90th percentile for this date. A deep dry layer does remain in place above the inversions.

Tonight and Thursday, the cold front will slow and become diffuse as it moves into South Florida, with no real change of airmass expected at the surface. However, enhanced low level convergence along the front, combined with the lingering moist axis of well above normal PW values, will continue to produce scattered to numerous showers, some of which may be locally heavy at times. The highest chances for rain and heavy downpours should be mainly across NE sections, including Palm Beach and eastern Broward Counties. Continued dry air aloft will limit the potential for thunderstorms, but a few storms will remain possible into early this evening and again on Thursday.

Otherwise, patchy fog will be possible again late tonight into early Thursday morning across the interior and along parts of the Gulf coast.

Thursday night into Friday, the remnants of the front will lift back to the north, as low pressure develops over the northern Gulf of Mexico. This will leave the forecast area in moist E to SE flow, but lacking any particular focus or trigger for convection. Continuing above normal PW values should allow scattered showers to persist, focused more along the coast at night, shifting into the interior during the day. Friday afternoon into Friday night, increasing moisture convergence through a deeper layer as the mid level trough and surface low advance east toward Florida may provide enough forcing to increase shower coverage, with isolated storms possible as well.

Long Term (Saturday through Wednesday) . A progressive upper air pattern will prevail across the CONUS during the long term period, with one trough moving offshore from the Eastern Seaboard during the weekend, and the next trough developing over the Plains and then advancing toward the East Coast through the middle of next week. On Saturday into Saturday evening, as the low pressure area mentioned above moves from the Gulf across the Southeastern states and up the East Coast, a trailing cold front will be dragged through South Florida. The deep moisture and lift will have exited from our region before the front arrives, so expect only isolated to widely scattered showers as the front passes through. Mainly dry and slightly cooler weather will prevail behind the front for the remainder of the weekend, although even across interior NW areas we expect lows to drop only into the mid-upper 50s.

Winds will quickly veer back around to E/SE on Monday due to the progressive large scale pattern, which will allow temps to warm back above normal, into the low-mid 80s. Thereafter, expect warm weather with isolated to widely scattered showers and perhaps a few thunderstorms to prevail ahead of the next front. Guidance indicates that this second front will probably be stronger than the weekend front, and current model timing brings it through South Florida on Wednesday.

Marine . Boating conditions will deteriorate overnight and Thursday, starting across the Gulf waters during the evening, where NE winds are forecast to increase to near 20 knots beyond 20 nm, and we have posted a Small Craft Advisory for that area from late this evening into Thursday morning. Winds are expected to increase to 15-20 knots across the Gulf waters within 20 nm, and will post Small Craft Exercise Caution headlines for those zones. On Thursday, increasing NE breezes and a building NE swell will impact the Atlantic waters, and Small Craft Advisories will probably be needed then. These impacts should peak Thursday night, then diminish on Friday as the swell subsides and winds quickly veer back to the SE and weaken. Generally benign boating weather is expected for the weekend.

Aviation . VFR conditions are expected to prevail at all South Florida terminals for the rest of this afternoon and evening. Scattered to widespread showers are expected through 00z, which will lead to brief bouts of MVFR to IFR conditions due to potentially low ceilings and very heavy downpours. Although a few thunderstorms cannot be ruled out, chances are too low to include in the TAF at this time and will be left for later TAF amendments, as necessary. Generally southeasterly winds at around 10 knots will gradually back late this evening to northeasterly.

Beach Forecast . Building northeast swell will likely bring increased rip current risk and rough surf to the Atlantic beaches on Thursday and Thursday night, especially for Palm Beach County. This swell will begin to subside on Friday, but at least moderate rip current risk will probably linger then.

Fire Weather . A cold front will continue moving southward down the Florida peninsula, stalling and becoming diffuse as it approaches South Florida tonight and Thursday. Increased moisture ahead of the front will support scattered showers and above normal relative humidity values, with no significant airmass change expected through the end of the work week. No significant fire weather concerns are anticipated.

Patchy dense fog will be possible once again late tonight into early Thursday morning across portions of the interior and Gulf coast.
