Area Forecast Discussion
National Weather Service Melbourne FL
902 PM EST Mon Feb 12 2018

Current-Overnight...Weak surface trough continues with slow movement
across the Deep South and northeast GOMEX this evening, perhaps
moving into the northern FL peninsula overnight becoming barely
discernible. Warm and humid conditions continue south of this
boundary. Local onshore winds will fall to light this evening and
overnight. Suspect we will see mainly cloudy skies, especially north
of the Treasure Coast, with some low clouds and patchy fog
developing. Lighter low-level winds tonight compared with previous
nights. Believe the greatest threat for any locally dense fog,
should it develop, will be near/north of I-4.

For precip, the lightning threat looks to be over with sea breeze
collisions unable to produce anything more significant than showers.
Due to the very moist low-levels, instability, and a few boundaries
remaining, it is not out of the question to see an isolated shower
from time to time, mainly north of I-4. Min temps in the M/U60s (10-
15F abv avg). Update to zone forecast package already sent.


.AVIATION...Mainly VFR thru this evening, but with deep low-level
moisture may see some MVFR-IFR CIGs/VSBYs overnight into early Tue
morning, especially along the I-4 corridor. Light onshore surface
winds tonight continuing NE/E on Tue. Some light precip possible
during the night near/north of I-4. Barely discernible frontal
boundary to the north with combined deep moisture may provide for
some convection, greatest threat continues along the I-4 corridor on


.MARINE...Overnight-Tue...Stagnant weather pattern continues with
weak frontal boundary to the north and weak ridging over the area.
The pressure gradient remains weak with continued light onshore
flow. Some patchy sea fog may be possible late in the night and
early Tue morning along the Volusia coast. Near shore seas mainly 3-
4 ft in a long period east swell to include offshore south of Ft.
Pierce. Seas mainly around 5 ft offshore north of Ft. Pierce. Some 6
ft seas possible on Tue well offshore Cape northward. Small precip
chances from mainly Cape northward.
