Most terminals should see no more than a sprinkle through the
evening, with pbi being the exception as showers are expected
nearby and offshore. As the front nears, winds and rain chances will
increase on Friday. Included a prob30 at apf since that terminal
might see some gulf showers that could produce sub-vfr impacts.

Otherwise,VFR is expected through most of the period except for
brief bouts of sub-vfr with fast moving showers.

Prev discussion issued 938 am est Thu dec 13 2018
update...

some shallow convection continues but the relatively dry
atmosphere is limiting much in terms of a wetting rain or even
minor accumulations. Have updated the forecast to mention
sprinkles this morning as that is what most area could possibly
see from this activity. Otherwise, the forecast is on track with
no additional changes.

Prev discussion... Issued 340 am est Thu dec 13 2018
discussion...

this morning's low temps are running around 10-15 degrees warmer
than this time yesterday morning as winds return from the east and
moisture content rises. With this in mind, Thursday's high temps
are forecast to reach the upper 70s across south florida with a
few near 80 temps in the SW region, right about average (perhaps a
degree or two higher in some spots) for this time of year. As
winds continue to veer to a more southerly direction throughout
the day today, an influx in low-level moisture will advect into
the region with derived pwat values approaching 1.25 inches. A few
showers can't be ruled out today through tonight, especially the
ne portions of the cwa, but most areas will remain fairly dry.

Friday into this weekend still remains the hot topic for weather
debate. As high pressure continues to push eastward into the
western atlantic and a rather impressive low pressure system
across tx swings into the gulf states, south florida weather will
be in a state of limbo as models continue to diverge. Now only
about 36-60 hours out, it is a bit unusual that both the global
models (gfs and ecmwf) continue to differ on fropa. GFS has
delayed a bit to a more Saturday morning to Saturday afternoon
fropa with both ECMWF and NAM agreeing on a Saturday night into
Sunday morning fropa. 06z wpc guidance for 12z Saturday morning
puts the cold front smack dab in the center of the cwa. Because of
this, grids are continuing to split the difference of the exact
timing of fropa, now trending towards Saturday morning to Saturday
afternoon time frame.

Based on this forecast timing, the bulk of showers and
thunderstorms would hold off until Friday night, with only low
chances during the day Friday for the east coast and a slight
chance for the NW portions of the cwa. Regarding risk of strong
convection, 06z SPC analysis for day 2 placed central florida and
northern florida in a slight risk, with a marginal risk touching
the northern fringes of lake okeechobee, central glades county,
and the far NW tip of hendry county. 0-3 km shear values are
approaching 40 kt across the regions as well, though the best
dynamics lift still favor to the north of the region. Regardless,
there appears to at least some risk of some strong wind gusts in
the projected convective band Friday night into Saturday morning,
especially over northern portions of south florida. Needless to
say, this risk and its evolution based on refinements to fropa
timing, will be closely monitored.

One things for certain is that the aforementioned cold front will
move through this weekend, bringing an end to shower and
thunderstorm chances as well as some cooler drier air. The timing
differences have already been mentioned, but by Sunday at the
latest, the front should clear the region.

Into early next week, high pressure returns and NW winds will
prevail, allowing for dry and pleasant conditions, along with
cooler temps back below climatological norms. Dry air will
continue to filter in through at least mid week.

Marine...

small craft exercise caution across the atlantic waters on
Thursday as E SE winds of 15-20 kt prevail. Seas will be 4-5 feet
with occasional 6 feet seas. Ahead of a week-end storm system,
south and southeast wind will increase late Thursday night into
early Friday morning, and this may necessitate an additional small
craft advisory for the atlantic waters.

Although a low chance of showers will exist beforehand, shower and
thunderstorm chances will increase Friday into Friday night as a
cold front approaches.

Beach forecast...

high risk of rip currents due to NE swell combined with E SE wind
of 15-20 mph is in effect for atlantic waters through Thursday
evening. This risk may continue into Friday.
