Area Forecast Discussion
National Weather Service Miami FL
636 PM EST Tue Jan 26 2021

.AVIATION(00Z TAFS)...
VFR conditions will prevail through the evening hours. Areas of
fog will develop during the overnight and early morning hours of
Wednesday. Some of the fog could become dense, especially at KAPF
and KTMB. Patchy fog is possible across the other east coast
terminals, however, that is more uncertain at this time. Fog will
begin to lift after sunrise on Wednesday and winds will increase
out of the southwest by the middle of the morning.

&&

.UPDATE...
A ridge of high pressure will remain in control of the weather
pattern across the region for tonight and into Wednesday as well.
Areas of fog will develop once again later this evening and into
the overnight hours especially across the interior and western
areas. Some of this fog could become dense during the overnight
hours with the greatest likelihood of this occurring in Glades,
Hendry, and Collier Counties. The fog will begin to lift after
sunrise on Wednesday morning. Dry conditions will remain in place
throughout the rest of the day. Winds will increase out of the
south southwest which will allow for warm temperatures to continue
as well. Highs on Wednesday will rise into the lower to mid 80s
across most of the region.

&&

.PREV DISCUSSION... (Issued 240 PM EST Tue Jan 26 2021)

SHORT TERM (Rest Of Today-Wednesday)...

An elongated ridge of high pressure over the western Atlantic
Ocean continues to strongly influence the weather pattern over
South Florida. With a gradual eastward progression and flattening,
winds are more southerly today as opposed to south/southeast in
prior days. This will allow for warmer air to advect over the
region, resulting in anomalously warmer temperatures through
Wednesday. With forecast maximum temperatures in the lower/mid 80s
tomorrow, record high temperatures may be challenged in some
areas.

The 12Z MFL sounding revealed several distinct temperature
inversions through the profile. First, a shallow yet stout radiation
inversion, responsible for retaining fog slightly past sunrise in
isolated locations this morning. With little change in the synoptic
pattern over the coming hours, this radiation inversion is likely to
redevelop overnight and support patchy/locally dense fog over South
Florida, with the greatest likelihood of formation and dense
coverage being west of Lake Okeechobee in portions of Collier,
Hendry, and Glades Counties. Second, several subsidence inversions
are apparent in the 950-750 hPa layer. This is commensurate with
stout ridging within the boundary layer, which is acting to severely
limit any potential rain chances through at least Wednesday.

By Wednesday night, a non-robust cold front is forecast to progress
towards the region. This will likely provide mild relief from the
higher recent temperatures, as well a slight chances for showers
ahead of the front. No significant impacts associated with the front
are anticipated at this time.

LONG TERM (Thursday through Monday Night)...

A cold front draped southward from a low pressure system moving off
the Mid-Atlantic will be moving through the area through the early
part of the day on Thursday. With the parent low well north of the
region there will be little forcing for any convection to develop
along and ahead of the front. Limited shower chances with anything
beginning to break up and dissipate as it reaches South Florida
early on Thursday. The main hazards will be behind the frontal
passage. As winds become northwesterly and increase behind the
frontal passage throughout the day Thursday there will be
deteriorating marine and coastal conditions. There will also be
the potential for elevated fire weather conditions Thursday
afternoon. See Fire weather section below.

Behind the frontal passage cooler and drier weather will filter down
the peninsula. High temperatures will be 10-15 degrees cooler on
Thursday compared to Wednesday. Low temperatures Thursday night/
Friday morning will be in the mid 40s west of the Lake to mid-
upper 50s for the east coast.

A mid-level ridge with high pressure developing across the eastern
CONUS. Winds will veer fairly quickly to NNE/NE as the sfc high
pressure will slide eastward as we end the week and move into the
weekend. With the easterly component and winds continuing to veer
to easterly a gradual warming trend with winds off the Atlantic
waters.

Another trough will be digging across the central US with another
low-pressure system moving through the Mid-Atlantic towards the end
of the weekend into early next week. This may bring another cold
front to South Florida on Monday, with another cool down for
early-mid next week. Exact timing may fluctuate as models get a
better consensus on timing of the frontal passage.

AVIATION(18Z TAFS)...
VFR conditions prevailing through the afternoon/evening. Winds
become light and variable around most sites at 02-04Z, with BR/FG
development possible over the interior. TMB and APF as well as
other interior locations (especially west of Lake Okeechobee) are
most likely to see IFR/LIFR conditions due to low CIGs/VIS
restrictions, mainly between 07-13Z. Conditions should rapidly
improve shortly after sunrise tomorrow. Winds generally SSE
becoming SSW with time.

MARINE...
Broad high pressure will allow for generally benign boating
conditions. Modest SE/SSE flow should persist through mid week. An
approaching front later in the week may result in deteriorating
marine conditions, as a fetch of NW winds acts to increase surf
heights. Swell activity may develop downstream of the front as well,
which could persist into the weekend.

FIRE WEATHER...
With a cold front moving through Wednesday night, a much drier air
mass will move into the region during the day on Thursday. Minimum
relative humidity values could fall below 35 percent on Thursday
afternoon mainly over the interior and western sections. At the same
time, 20 foot winds are forecasted to be near 15 mph over some
sections. This will continue to be closely monitored over the next
several days.

BEACHES...
A high risk for rip currents is in effect for coastal Palm Beach
County through Tuesday evening, as modest SE/SSE flow of roughly 15
kts persists through the afternoon. This flow becomes slightly
weaker into Broward/Miami-Dade Counties, and hence a moderate risk
for rip currents is effect for these areas. An approaching front
later this week may result in a high risk for rip currents across
the region.
