Gusty showers are moving across the Atlantic terminals with some
of the strongest cells producing brief gusts to around 37 kt at
times. A brief MVFR period is also possible on the Atlantic
terminals with VIS dropping below 3SM under heavy showers through
10Z. The breezy conditions will continue today, then subside a
little later tonight.
PREV DISCUSSION... /issued 711 PM EDT Wed Oct 26 2016/
Latest radar and satellite imagery show a band of showers
starting to develop over the Atlantic traveling westward
into the southern Atlantic Metro area. Higher concentration
of blended total PWATs ranging from 1.0 to 1.4" will continue
to surge into the southern zones of S Florida tonight. This
broken to overcast cloud deck will prevail through the night
with the potential for light brief showers increasing through
the night into Thursday. Only changes done to the forecast were
extending pops into inland Miami-Dade where a few light showers
are already making their way inland this evening. The remainder
of the forecast remains on track.
PREV DISCUSSION... /issued 411 PM EDT Wed Oct 26 2016/
An area of high pressure over the Southeastern portion of the
country will continue to slowly move east tonight through
Thursday. Moisture will continue to slowly increase tonight and
tomorrow as well. Light showers will still be possible tonight
over the Atlantic Coastal waters and the East Coast Metro areas.
Conditions are expected to remain similar during the day on
Thursday with a gusty east to northeast wind and a chance of
showers as well. There could be enough instability especially over
southern areas to support a slight chance of thunderstorms during
the afternoon hours.
High pressure will continue to remain off to the north later this
week and into early next week. This will help maintain the east to
northeasterly wind flow across south florida. Both of the GFS and
the ECMWF continue to show some drier air moving in from the north
early next week. This will help lower any shower chance across
East to Northeast flow will continue through Thursday near speeds
of 20 to 25 knots. A small craft advisory will remain in effect
for both of the Atlantic and Gulf waters through Thursday. There
could be a few showers. Conditions may improve slightly this
weekend, however, the advisories still may have to be extended.
