Area Forecast Discussion National Weather Service Miami FL 256 AM EST Sat Jan 25 2020

. DENSE FOG ADVISORY IN EFFECT INTERIOR/WEST COAST UNTIL 8 AM EDT THIS MORNING .

. HIGH RISK OF RIP CURRENTS BEACHES OF PALM BEACH COUNTY .

Short Term. Fog is developing early this morning over the interior and west coast metro areas. The fog should continue to develop and should become dense in some areas through rest of the early morning hours with visibilities falling down to 1/4 of a mile or less. The fog should also spread into the east coast metro areas toward sunrise reducing the visibilities. Therefore, a dense fog advisory has been issued for the interior and west coast metro areas early this morning until 8 AM EDT. The east coast will also be monitor for possible dense fog and if the dense fog does form towards sunrise then a short fused dense fog advisory will be needed.

The fog should burn off through the morning hours, as a cold front over Central Florida continues to move southward and through South Florida during the day hours today. The passage of the cold front will allow for a northerly wind flow which in turn will allow for drier and cooler weather to work into the region from the north for tonight into Sunday.

Highs today will be in the 70s over most areas, except around 80 over the southern interior areas of South Florida. Lows tonight will fall into the 40s over most areas, except lower to mid 50s east coast metro areas and around 40 west of Lake Okeechobee. The winds will be light tonight, so no wind chill issued over South Florida. Highs on Sunday will be only getting up into the lower to mid 70s, except around 70 west of Lake Okeechobee.

Long Term.

Monday through Tuesday Morning .

A complex and progressive pattern remains established through late week as broad troughing, and a series of shortwaves encompass the CONUS. With that said, the forecast continues to be challenging for the beginning of the week with respect to a surface low that is forecast to develop over the Gulf of Mexico late Sunday/early Monday. The generation of the low will be in response to the first shortwave perturbation of the period. As the system closes in on the Florida peninsula, a remnant boundary to our south is progged to lift northward, increasing instability across South Florida. Uncertainty in timing has arisen with the latest GFS and ECMWF guidance slowing the forward propagation of the system as it reaches our area. This has resulted in rain chances to begin increasing early Monday and continuing through early Tuesday.

Moreover, incessant variability from run to run regarding the system's intensity has compounded uncertainty in the forecast. Although the ECMWF has maintained some congruity, the GFS is now much weaker than previously suggested. This seems to be due to the shortwave's deamplification as it approaches the area. Despite this, when comparing forecast soundings at various locations, there remains a non-zero chance for stronger convection that may be capable of producing isolated wind gusts, lightning, and minor localized flooding. Therefore, PoPs maintain scattered to numerous coverage across the area, especially for the Gulf and Atlantic waters. At this time, have kept the mention of isolated thunderstorms in the event there is adequate instability, moisture, and shear across the region, which are reflected in forecast soundings. As always, will continue to monitor over the upcoming weekend as the finer details should come into better focus.

Tuesday through Wednesday .

Mostly dry conditions resume through the middle of the week as the system journeys further into the Atlantic. While high pressure briefly returns, a synoptic pattern comparable to the one at the start of the week is progged to set up. This means increasing rain chances are possible across the region as another, albeit weak shortwave crosses the Gulf of Mexico on Wednesday. But to no surprise, there are model discrepancies with this system. Currently, the GFS has the low and associated moistures passing north of the region, whereas the ECMWF dampens the low over the Gulf before it has a chance to reach the state. Thus, have split the difference and kept a slight chance of rain in the forecast, mostly over the Gulf and Atlantic waters.

Thursday through Saturday .

Modest confidence returns for the tail end of the period as both the GFS and ECMWF reveal yet another area of unsettled weather approaching Florida ahead of the next, deeper amplifying southern stream trough. Per usual, coverage and intensity this far out in time is subject to change, and for that reason, have not strayed from guidance.

Temperatures for the extended period will remain close to seasonal averages with daytime maxima in the 70s across South Florida, and overnight lows in the 50s to 60s near the east coast.

Marine. The winds will swing from a light southerly flow early this morning to a light northerly flow today as a cold front moves through the local waters. The winds will remain light from the northerly direction tonight into Sunday before going southerly on Monday around 10 knots ahead of a another cold front.

A Small to Moderate northeast swell will continue to affect the Atlantic waters of Palm Beach county this weekend into early next week. This will keep the Atlantic Seas of Palm Beach County around 2 to 4 feet, while rest of the Atlantic waters will remain at 2 feet or less. The Gulf seas of South Florida will also remain at 2 feet or less through early next week.

Aviation. The winds will be light tonight before going northerly at 5 to 10 knots with a cold front passage. Fog will continue to develop through the early morning hours over the TAF sites allowing for the vis and ceilings to drop down into the IFR or even LIFR conditions. The fog should burn off around 12/13Z as the cold front pushes southward through the TAF sites leading to VFR conditions late this morning into tonight.

Beach Forecast. Small to moderate northeast swell will continue to affect the Atlantic waters of Palm Beach County today into Sunday. Low tide will also be occurring this afternoon along the east coast beaches of South Florida. The combination of the northeast swells and low tide will lead to a High Risk of Rip Currents for the beaches of Palm Beach County through Sunday. Therefore, the High Risk of Rip currents will be extended through Sunday evening for the beaches of Palm Beach County. A Moderate Risk will also be up for the beaches of Broward County through Sunday.

Fire Weather. The drier air on Sunday over South Florida will allow for the relative humidity to fall down into the upper 20s to lower 30s over the interior and west coast metro areas with the east coast metro areas falling into the mid to upper 30s. However, the 20 foot winds will remain below 15 mph over all of South Florida on Sunday. Therefore, NO fire weather concerns are expected on Sunday over South Florida.
