Area Forecast Discussion
National Weather Service Miami FL
705 AM EST Thu Feb 9 2017

.AVIATION...

Latest split channel satellite imagery indicates widespread dense
fog across most of the South Florida peninsula with periods of
IFR ceiling and visibility restrictions possible all terminals
through at least 13z and could persist to near 14z, will amend as
needed. A diffuse cold front will pass into and across South
Florida later today, although IFR restrictions not anticipated.
Light southwesterly winds this morning will transition to
northwesterly around 18z and increasing to 10 to 15 knot range
with higher gusts possible.

60/BD

&&

.PREV DISCUSSION... /issued 451 AM EST Thu Feb 9 2017/

DISCUSSION...
Today through Friday: Latest surface analysis shows a cold front
draped along the Southeast CONUS from the Carolinas down towards
southern Texas. This feature will be the main influence for our
weather during the next 24-hours. Persistent light west-southwest
flow, ahead of the front, has helped to increase low level
moisture. With clear skies and good radiational cooling in place,
temperatures will continue to fall to their dewpoint through the
next several hours. Fog, with visibility down to near 1/4 mile,
has already been reported between mile marker 30 and 50 on I-75.
Areas of fog should become more widespread with time, affecting
all zones though day break. The SREF model progs the fog to erode
between 7 and 10 am, as the sun begins to heat the surface.
Limited moisture today and weak instability may be enough to
produce a few spotty showers this afternoon. Hi-Res models
indicate most of the activity to remain over the central and
northern portions of the CWA. Maximum temperatures will be toasty
again today with only a few clouds around and light westerly flow.
Forecast highs are in the low to mid 80s, around 6 to 8 degrees
above normal for this time of year. These values will also be
approaching daily maximum records. Both the GFS and ECMWF have
been consistent with dropping the aforementioned cold front
southward over the region tonight. On Friday, behind the frontal
boundary, winds will shift to the north, advecting in a cooler and
drier airmass. Max temps are may only reach the mid 70s, a couple
degrees cooler than normal.

Saturday through mid next week: A rather seasonal and benign weather
patten is expected to develop. Long range models build an upper
level ridging pattern over the southeast CONUS. Subsidence aloft
should help to bring a slow warning trend back to South Florida.
Surface high pressure drifting across the western Atlantic will
generate light easterly low-level flow over our region. Otherwise,
dry conditions are forecast to prevail. Our next chance for
measurable precipitation appears to be mid to late next week,
when the next cold front approaches.

MARINE...
West winds will gradually veer to the northwest 10-20 KT by this
afternoon. Small craft should exercise caution. A passing cold
front tonight into Friday morning will increase northerly winds
and waves across the waters. Wave heights tonight may range from 6
to 9 feet, highest along the Gulf Stream. Seas will begin to
slowly lower late Friday through the weekend.

AVIATION...
Light westerly wind, saturated low-levels, and clear skies are
allowing fog to develop early this morning, and expect IFR/LIFR at
climatologically favored KTMB and KAPF to continue through at
least 13z. Restrictions also possible pretty much everywhere but
KFLL, but confidence is too low to include in TAFs ATTM. After fog
gives way, expect occasional 4-12 KFT CIGS to occur during the
afternoon, before clearing skies tonight. SW winds this morning
will turn WNW, with some gusts approaching 20 KT this afternoon as
a cold front moves through the area. Late tonight, guidance
suggests onshore flow developing along east coast terminals, but
this should hold off until after daybreak Friday.
