Area Forecast Discussion National Weather Service Miami FL 1238 AM EST Sat Jan 23 2021

AVIATION(06Z TAFS). MVFR and occasional IFR expected in fog/low ceilings over inland and western sections of South Florida, mainly affecting TMB and APF terminals through 14z. Some of these conditions could affect some of the larger east coast airports during the 08z-14z time frame, but much less certainly on this and therefore not included in forecast for now. After 14z, VFR conditions to prevail with westerly wind becoming NE-E 10 kt or less east coast by 18z.

PREV DISCUSSION. (Issued 638 PM EST Fri Jan 22 2021)

AVIATION(00Z TAFS) . VFR conditions will prevail this evening. Areas of fog will develop later tonight into early Saturday morning especially across the interior and western areas. This could cause periods of MVFR and localized IFR across these areas including KAPF and KTMB. Short fused amendments may be needed as the fog develops. The areas of fog will dissipate after sunrise Saturday morning and VFR conditions will prevail throughout the rest of day.

UPDATE . An area of high pressure will continue to dominate the weather pattern across the region for tonight. Winds will become light and variable this evening. With sufficient low level moisture in place, light winds, and lack of cloud cover, areas of fog will develop later tonight into early Saturday morning especially over the interior and western areas. Some areas could see locally dense fog in these areas during the overnight hours. The areas of fog will start to dissipate after sunrise on Saturday morning allowing for dry conditions to continue throughout the rest of the day. High temperatures on Saturday will remain on the warm side as they will rise into the upper 70s to around 80 across South Florida.

PREV DISCUSSION . (Issued 309 PM EST Fri Jan 22 2021)

Patchy Fog Possible Late Tonight into Early Saturday AM.

SHORT TERM (Rest of Today through Saturday) .

Not much going on in the South Florida weather world, with dry and pleasant conditions expected for the remainder of today. Due to sufficient boundary layer moisture, light winds, and lack of clouds, model consensus hints at another round of fog tomorrow morning. One thing to note is that models are a little more robust than previous days, so wouldn't be surprised to see some dense fog developing in the interior/western sections of the region and oozing into the eastern metro areas late tonight through early tomorrow morning. At this time, added "areas" of fog in western and interior sections of the CWA with "patchy" wording elsewhere in the forecast. Frankly, due to the bullish nature of the models and medium to high confidence on seeing some dense fog developing, would not be surprised for fog products to be issued during the overnight hours.

Going into the weekend, a backdoor cold front approaches South Florida, shifting our prevailing high pressure southeastward into the Atlantic, keeping a WSW to W flow through the short term period. As this front continues to sag southward, available moisture will decrease as the front continues to decay before eventually washing out. Due to the proximity of the frontal boundary, kept small silent PoPs across the Atlantic waters Saturday night through Sunday, though don't anticipate much more than a sprinkle as strong subsidence aloft sticks around.

Saturday morning lows are forecast to be in the mid-50s to near 60 with afternoon highs approaching the mid-upper 70s to near 80 in interior sections.

LONG TERM . Saturday Night Through Thursday Night .

The weak frontal boundary that is moving towards the area, actually stalls Saturday night as high pressure pushes to the southeast, to the east of the area. The southeast flow on the southwest side of the high, actually pushes the front to the south, east of the area, causing the tail end to move to the northwest. This will keep showers out of the area for the most part. The exception may be near Jupiter and the adjacent waters, and even then it is just a slight chance through Sunday evening.

Most of the remainder of the forecast period will be quiet weather under high pressure. It isn't until late Thursday that the next front approaches the area. Even then, the NBM is a little too quick with the front compared to the GFS and ECMWF, which do not bring the front into the area until Thursday afternoon or evening. However, The NBM does keep the frontal passage dry. The two synoptic models show the front coming through fairly dry, maybe some light showers. The other thing to note is the wind behind the front should be northeasterly, which would indicate that the air mass will be moderated by the marine environment, and may not have significant cold air associated with it. However, this is still a week out and the pattern and timing could change dramatically.

AVIATION(18Z TAFS) . Mainly VFR conditions expected into early tonight, then some areas of MVFR/localized IFR conditions may develop, especially for inland and western areas, including KAPF. Fog prone airports, i.e. KTMB and KOPF, may have CIG/VIS concerns between 9-14z tomorrow AM if fog bleeds eastward. Handled with BR for now, but AMDs may be necessary as confidence grows. SW winds this afternoon become light and variable overnight before quickly veering N then NE by the end of the forecast cycle.

MARINE . High pressure across the local waters will maintain benign marine conditions over the next several days with no meaningful weather impacts anticipated. By late weekend, a weak frontal boundary will move across the waters with cautionary conditions possible early next week in its wake, with building swell and seas across the northern Atlantic waters.

BEACHES . An elevated rip current risk may exist late this weekend into early next week for the east coast beaches as northeasterly swell builds into the Atlantic waters of South Florida.

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