Area Forecast Discussion
National Weather Service Miami FL
641 AM EST Sat Jan 19 2019

.AVIATION...
Cold front moving through the area late in the period will be the
main weather-maker. It will likely be accompanied by some showers,
and a thunderstorm or two cant be ruled out overnight into early
Sunday. VFR conditions should prevail but some MVFR CIGs (and
possibly VSBY in heavier showers) are possible, and this may need
to be included in TAFs at a later time. SE wind today will
increase to 10-15 KT by afternoon, then gradually veer SW at
similar speeds tonight. NW wind is expected after 12z Sunday.

&&

.PREV DISCUSSION... /issued 351 AM EST Sat Jan 19 2019/

DISCUSSION...
TODAY: High pressure has shifted east over the Atlantic with winds
veering southerly to southwesterly ahead of an approaching cold
front. Temperatures will be above average with high temps along
the east coast in the upper 70s approaching 80 degrees today.

TONIGHT THROUGH MONDAY: A low pressure developing over the
Southern CONUS has a cold front draped to its south moving across
eastern Texas and entering the Gulf of Mexico. Models are in
fairly good agreement with the timing of the front moving across
the Gulf today and moving into our region late tonight/ Sunday
morning. As the front approaches Sunday it will outrun most of the
upper level support. The vort max and the upper level jet will
stay north of the region, with the best chance of thunderstorms
staying to our north across Northern and Central Florida. Ahead of
the front a few showers will be possible, but overall the main
line will be a broken line of showers with a few embedded
thunderstorms possible. With any of the thunderstorms that do a
develop a few gusty winds 30 to 40 MPH will be possible. The front
should exit the region by Sunday evening allowing colder and
drier air to filter into the South Florida peninsula.

Cold Air advection behind the front will allow low temperatures
Monday morning be in the upper 30s around the Lake Okeechobee
region, low to mid 40s across the interior and Gulf Coast, with mid
to upper 40s over the east coast metro. Winds will allow the
apparent temperatures to be a few degrees colder. As of now winds
will remain elevated enough to keep the mention of frost out of the
forecast for Glades County. Will have to monitor the winds if they
relax and lighten some, then there may be some frost potential in
portions of the Lake Okeechobee region.

High pressure develops behind the front Monday and moves quickly
east into the Atlantic keeping the cold air advection short lived,
with winds becoming northeasterly Monday night helping to moderate
temperatures overnight.

TUESDAY-FRIDAY: High pressure dominates through mid-week with
easterly flow becoming southeasterly, ahead of another cold front
approaching the region. Models have come into better agreement on
timing being Thursday into Friday. Another chance of rain and cooler
temps behind the cold front.

MARINE...
Southeasterly to southerly winds ahead of an approaching
cold front moving into the region tonight into Sunday morning.
Gusty winds and increasing seas will lead to hazardous marine
conditions beginning early Sunday morning. A Small Craft advisory
will likely be required across all South Florida waters as early
as Sunday morning. Winds will increase out of the NW around 20 -25
knots with higher gust around 30 knots. Seas in the Gulf will
build 7 to 9 feet, and seas in the Atlantic build 4 to 7 feet,
with highest values in the Gulf Stream and offshore Atlantic
waters.

...MODERATE RISK OF RIP CURRENTS PALM BEACH AND GULF COAST COUNTY BEACHES...
...NEXT WAVE OF COLD TEMPERATURES SUNDAY NIGHT BEHIND A FRONT...
...HAZARDOUS BOATING CONDITIONS ATLANTIC AND GULF WATERS...

This is the hazardous outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Lightning: Isolated thunderstorms over the Gulf waters after midnight.
Strong gusty winds over 35 mph could accompany a few of the storms.

Rip currents: There is a moderate risk of rip currents along the
Palm Beach County beaches through this evening and along the Gulf Coast
beaches after midnight.

Temperature: Apparent temperature values are forecast near 45 to 50 degrees
across the interior west of Lake Okeechobee this morning.

Wind: Becoming southerly and increasing to 15 to 25 knots over the Gulf and
Atlantic waters after midnight ahead of a cold front. This will create
hazardous boating conditions for small boaters.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

The rip current risk will increase to high along the Gulf Coast beaches
Sunday through Monday. The rip current risk for Atlantic beaches increases
to high Tuesday through Thursday.

In addition to rip currents, some beach erosion will be possible along Gulf
Coast beaches Sunday and Sunday night as surf increases along area
beaches.

Numerous showers along with isolated thunderstorms will be possible
across the entire area on Sunday as a cold front pushes through
during the morning and early afternoon hours. Wind gusts in excess
of 40 mph will be possible with strongest storms.

Gusty winds and building seas in the wake the front will likely lead to
hazardous marine conditions over all local waters Sunday and Monday.

Cold temperatures are expected in the wake of the front. Low
temperatures Sunday night are forecast to range from the upper 30s
across Glades and Hendry counties to the upper 40s along the East
Coast with wind chill values ranging from the low 30s to the mid
40s. Low temperatures recover some Monday night, ranging from the
mid 40s west of Lake Okeechobee to near 60 along the East Coast.
Some wind chill values in the mid to upper 40s will still be
possible Monday night from around Lake Okeechobee to the Gulf
Coast.

An elevated fire weather risk is forecast for SW Florida on Monday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated, however, individual spotters
are encouraged to report high wind to the National Weather Service
forecast office in Miami.
