.PREV DISCUSSION... /issued 753 PM EST Thu Dec 14 2017/

A quiet evening weatherwise across South Florida with a few clouds
streaming over the lake region. Expect things to clear out for the
most part, though some high cirrus is possible overnight. Forecast
appears to be on track for this evening, with only minor updates
made to show a bit cooler temperatures for the overnight with the
latest guidance. Updated zones have been transmitted to account
for this, although most populated areas saw minimal change with
the largest focus over inland Southwest Florida for tonight with
this update. Have a great evening!

Latest WPC surface analysis shows a 1019 mb broad high over the
Fl straits extending across the southern Fl peninsula. This
feature has allowed for mostly clear skies, dry atmospheric
conditions, and light winds. High pressure moves offshore
beginning tonight leading to a warming trend and a continuation
of dry and benign conditions. Min temps much milder tonight
and forecast to warm into the mid/upper 70s most areas Friday
afternoon with slightly cooler afternoon temps along the Se Fl
coast due to local seabreezes. Min temps even milder Friday night
with lows in the 50s inland and 60s along the coast.

This weekend through early next week: By Saturday, mid range
models prog upper level ridging to slide eastward and build over
the southeast CONUS. Surface high pressure strengthening to the
north of our region will act to veer flow out of the east or
southeast, leading to a gradual increase in low level moisture.
Rising 500 mb heights aloft will generate a warming trend through
early next week. Maximum temperatures are forecast to generally
reach near 80 on Saturday, low 80s Sunday, and even reach the low
to mid 80s on Monday and Tuesday. With lack of any significant
weather disturbances passing by, expect little to no chance of
precipitation through the extended.

MARINE...High pressure will continue to build across South
Florida the next few days, leading to light and somewhat
variable winds. A weak frontal passage on Saturday will bring
stronger northeasterly flow around 15 knots, veering easterly on
Sunday. No significant rain chances through the period.

FIRE WEATHER...Stagnant high pressure over the region will
continue to build during the next several days, leading to dry
weather and light winds. Thus, expect poor dispersions over a
majority of South Florida again Thursday afternoon. Dispersions
increase some over the weekend as high pressure moves offshore.
Developing southeast flow this weekend will bring a slight
increase in low level moisture, keeping RHs above critical values.
No appreciable rain chances are expected through the period.
