Area Forecast Discussion
National Weather Service Key West FL
217 PM EDT Thu Apr 6 2017

.DISCUSSION...
The line of showers with a few thunderstorms in the southeast Gulf
of Mexico has diminished significantly over the past hour or so.
Long range echoes from KAMX doppler show almost nothing that would
amount to much precipitation anywhere in the Keys service area at
this time. Winds in the northwestern Gulf waters are already
turning to the northwest, and starting to accelerate. Moderate
southwest winds elsewhere will continue a similar transition
through this evening. Upper clouds have thickened enough to be
considered mostly cloudy along the island chain, and temperatures
along the island chain are in the mid 80s.

The cold front currently stretching from the Collier County/Mainland
Monroe County line in southwest Florida through the southeastern
Gulf of Mexico will advance steadily southeastward through this
evening, to be south of the Straits of Florida by the small hours
of Friday morning. Although there will be some layered clouds
early this evening in our vicinity as the front transitions
through, we are expected at least some significant breaks in the
coverage by later this evening. Will probably use some
transitional wording for the sky conditions in the first period of
the zones on that account. But, based solely on the latest loops
of radar and satellite imagery, will be removing the mention of
measurable precipitation for the first period of the coming
forecast. Other than that, the latest round of model solutions
suggest making no significant changes to the forecast we already
have in place. Expect a few cool days thanks to the moderate to
fresh northerly breezes, driven by a large area of high pressure
sliding eastward along the northern Gulf coast. By late Sunday,
the center of this high pressure should be just off the southeast
coast, turning our winds more deeply to the east. From that point
through the duration of the forecast, will hold on to only a
minimal chance of showers. Conditions will rebound closer to
seasonal expectations as far as temperatures are concerned, but
without the elevated humidity that we have been experiencing over
the past several days.

&&

.MARINE...
Prefer the latest GFS solution which shows a more uniform push of
northwest/north winds through the area from this evening through
the overnight period...closer to 20 knots. Mixing should keep is
characteristically gusty as well. So, a small craft advisory will
be in effect when the afternoon coastal waters forecast is issued
in a short while. There will likely be some speed modulations to
the northerly breezes Friday and Saturday, especially through the
daytime hours for locations closer to the mainland. More moderate
winds are expected late Saturday through Sunday before winds
transition to northeast/east and freshen again on the southern
periphery of large high surface pressure off the southeast coast.

&&

.AVIATION...
A broken line of weak rain showers is moving southeast through the
Gulf of Mexico. We expect this line to mostly disintegrate as it
approaches the EYW and MTH terminals late this afternoon (20 to
22Z). Thereafter, gusty northwest to north crosswinds will impact
both terminals through the remainder of the forecast period. It is
uncertain if MVFR stratocumulus will develop overnight due to weak
cold air advection behind the passing cold front.

.CLIMATE...
With a low temperature of 79 degrees on April 5th at the Key West
International Airport, a new warm minimum temperature record was
set. This broke the old record of 77 degrees, which was last
observed in 2009. Temperature records in Key West date back to 1872.
