area forecast discussion
national weather service miami fl
714 pm edt Wed oct 18 2017

Update
Showers continue to spread across the area as a cold front
boundary settles over south florida. Radar data was showing most
of the larger showers developing over the atlantic coastal waters
and moving southwest, mostly over the atlantic metro areas. Some
of the showers are capable of producing waterspouts, with a report
from a weather service meteorologist about a waterspout moving
towards biscayne bay around 705pm edt.

The rainy pattern will continue through Thursday morning, then
gradually decreasing in coverage starting Thursday afternoon.

Current pop wx grids look reasonable, which include low chances
for a few thunderstorms this evening. Therefore, no significant
changes to the forecast are required for the evening update.

Discussion...

short term (tonight-Friday)... Model and satellite data show a
mid upper lvl trough over the eastern seaboard slowly migrating
into the atlantic waters, while an associated sfc cold front
continues to move across south florida. The front is expected to
stall over the area tonight, keeping dense cloud cover and
scattered to numerous showers at times. Best chances for rain
remain in the southern-most areas, especially homestead and the
southern tip of the peninsula. But areas of showers developing
over the atlantic coastal waters will also move over most of the
east coast metro areas through the evening hours.

The front is not expected to bring a significant cooling across
south florida with most locations remaining near normals.

A drier pattern will begin establishing on Thursday as high
pressure begins to build across the region in the wake of the
fropa. However, there should be enough lingering remnant moisture
for some showers to develop each day, especially in the afternoon
hours.

Long term (Friday night-Tuesday)... Building high pressure over the
western atlantic will bring tighter pressure gradients across the
region with winds shifting to a more ene flow and breezy at times
during the weekend. Some showers will be possible each day, but
drier than the short term. The high pressure will weaken during
the first half of next week as a trough deepens across the se
states. In response to the approaching trough, winds will turn to
southeasterly and southerly, along with increasing moisture over
florida.

Marine...

n NE winds continue during the next few days, with speeds to 20
kts on Friday. Winds will become more easterly later in the
weekend but will remain breezy through the weekend. Seas in the
atlantic waters will be up to 5 to 7 feet for the rest of the week
and into the first part of the weekend.

Beach forecast...

with increasing ne-ene winds later this week corresponding with
high astronomical tides, water levels may approach coastal flood
advisory criteria later this week.

Aviation...

the winds will remain northeast around 10 knots this afternoon
before decreasing to light and variable conditions tonight.

There could still be some showers around the TAF sites this
afternoon into tonight, except only during the day hours for kapf
taf site. Therefore, vcsh will continue for all the east coast taf
sites through tonight, and vcsh until 00z tonight for kapf taf
site. The ceiling and vis will remain inVFR conditions through
tonight, except dropping down into MVFR conditions with any
passage of the showers.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
