Area forecast discussion, Jun 6, 3:37 PM EDT, 4 hours 9 minutes before
Area Forecast Discussion
National Weather Service Miami FL
337 PM EDT Tue Jun 6 2017

.DISCUSSION...
A busy pattern for the next several days, and into next week. A
low pressure system over the Louisiana coast, is forecast to
slowly slide to the east, and even southeast, towards Central
florida. Models show it will take the rest of the week before it
crosses the Florida peninsula. This will keep showers and
thunderstorms in the forecast into the weekend, at least. GFS Theta
E graphics show moisture will move across the CWA in waves,
allowing for some breaks in the rain, especially in the overnight
hours.

For tonight, the boundary will lay somewhere from south Collier
County across, into northern Palm Beach County, with higher values
to the north. By 12z, however, the drier air will be pushed off
the east coast, with showers developing across the area once
again. With PWATs continuing to be over 2 inches over various
portions of South Florida through the night, and into tomorrow,
have issued a Flood Watch for all areas except Mainland Monroe,
where flooding is more difficult, and Glades County, where not as
much rain has fallen today, through 00z Thursday. This may even
need to be extended, if chances of rain continue to be high, given
the saturated nature of the area at this time.

As the low approaches Central Florida for the latter half of the
week, some drier air, but not necessarily dry air, will make its
way into at least some of the area. This will be mainly over the
western lake region, western interior, and coastal naples area,
where PWATs . The other half of the CWA may still see PWATs just
below 2 inches. Models are still indicating higher PoPs for this
area through Sunday, as a weak boundary remains over the CWA,
behind the low, as it finally exits to the northeast.

by the beginning of next week, a bermuda high strengthens,
bringing a more typical summertime pattern back to South Florida,
with chance PoPs across the region.

&&

.MARINE...
Showers and thunderstorms will continue to be possible across all
South Florida waters through the beginning of next week. The wind
will continue to run between 20 and 25 kts across portions of the
Gulf through 06z. Given this, the small craft advisory has been
extended through 06z tonight. After this small craft should
continue to use caution in a coastal South Florida waters for the
next several days.

&&

.AVIATION...
The winds have remain light and variable this morning into early
this afternoon. The short range models continue to show light and
variable winds rest of this afternoon into tonight for all of
South Florida taf sites. The short range models also continue to
show showers to affect the northern areas of South Florida through
rest of this afternoon before decreasing in coverage tonight.
Therefore, SHRA along with VCTS will be put in for KAPF, KFLL,
KFXE, and KPBI taf sites. For KOPF, KMIA, and KTMB VCSH will will
be in place through the afternoon hours. For the overnight hours,
VCSH will remain in place over all of the taf sites. The ceiling
and vis will remain in VFR conditions outside of the showers and
thunderstorms, but could fall down into MVFR or even IFR
conditions with any passage of showers or thunderstorms.

&&

.HYDROLOGY...
Abundant rain, across almost all of South Florida, has likely
saturated much of the soil. Given the high amounts of moisture in
the atmosphere, which will continue through at least tomorrow, and
the high chances of heavy rain, have issued a Flood Watch for all
Counties, except Mainland Monroe and Glades County. However, if
Glades begins to see higher amounts of rain overnight, they also
may need to be added to the watch. Some of the rainfall totals
across the area are significant, including 10.27 inches in
Everglades City, 14.68 5 miles NE of Everglades City, and 9.83
inches in Marco Island. These are not storm totals but only
amounts through around 2 pm edt today.
