Area forecast discussion 
National Weather Service Miami Florida
332 PM EDT Wednesday may 6 2015

Synopsis...
low pressure will move north away from the area this week...with
high pressure building in in its wake. Diurnal showers will be
scattered and focused over the interior.

&&

Short term /tonight through Friday night/...
low pressure north of the Bahamas has organized today...and NHC
now gives this feature a 60 percent chance of formation by Friday.
Regardless of development...the system will continue moving
northward...away from South Florida.

This afternoon convection has been slow to fire and there is
uncertainty as to whether or not it will develop at all. Chance
probability of precipitation areawide through 0z may need to be adjusted down if current
trends prevail. By late this evening...and showers/storms will
have dissipated.

Temperatures will exhibit a gradually warming trend for the
remainder of the week...as subtropical ridge takes hold. Rain
chances will be diurnal in nature...with greatest coverage over
the interior...where sea-breezes will be during maximum heating.

Long term /Saturday through Tuesday/...
this weekend into next week...little change in the weather
pattern. Subtropical ridging will dominate...providing South
Florida with Summer-like weather. Above normal temperatures and
isolated/scattered showers are expected.

&&

Aviation...
it is still not clear if an East Coast sea breeze will develop
this afternoon. Models are less excited about this scenario. The
flow around the low pressure seems to be strong enough that the
most likely scenario is for the Gulf Breeze to interact with the
the northwesterly flow over the interior to generate showers and
possibly a thunderstorm or two. For now, have included thunderstorms in the vicinity only
for pbi and vcsh for all the other airports except for apf.

&&

Marine...
winds and seas will continue to subside tonight and
Thursday. Swell from the low pressure north of the Bahamas may
impact the area in a few days depending on how much it
strengthens. Winds will be fairly light and variable into the
weekend...as high pressure settles in.
