.DISCUSSION...
Issued at 1030 AM EST Mon Feb 6 2023
A beautiful Monday is on tap for the Florida Keys island 
communities and coastal waters. Current temperatures are in the 
mid 70s, with dewpoints in the lower 70s. Marine observation 
platforms are recording northeast winds at 10 to 15 knots. KBYX 
is currently depicting light showers just off our waters of the 
Straits of Florida. 

Surface analysis depict a potent low pressure system just out of 
the northeast continental U.S. with its associated "front" over 
Cuba. In addition, a high pressure system is building near the 
Gulf States. Closer to home, our sensible weather today will be 
dominated by a mean level ridge currently located in the Gulf of 
Mexico. This ridge will propagate east throughout the day and dry 
out our atmosphere and we are seeing evidence of this on our 12Z 
RAOB. This morning sounding sampled a very dry and stable layer 
above 700 mb. However, we still have some patchy low to mid level 
moisture, therefore, a 10 percent POP seems appropriate for today.
Based on this, no changes are planned or needed at this time.

.MARINE...
Issued at 1030 AM EST Mon Feb 6 2023
No watches, warnings, or advisories are in effect for the Florida
Keys coastal waters at this time. However, Small Craft Advisories
may be required tonight for portions of the Straits of Florida and
Hawk Channel. High pressure will build across the eastern United 
States, resulting in freshening northeast to east breezes this 
evening. Fresh to strong easterly breezes will continue through 
the middle of the week as the high pressure builds into the 
western North Atlantic and offshore the southeast United States. 
Winds will turn out of the southeast and slowly decrease Thursday 
and Thursday night as the high pressure moves further east. A cold
front will approach the Florida Keys and adjoining coastal waters
late Friday.

.AVIATION...
(15Z TAFS)
Issued at 1030 AM EST Mon Feb 6 2023
VFR conditions will prevail at both EYW and MTH through the TAF 
period, although there may be some brief bouts of MVFR ceilings 
overnight tonight at either terminal. Near surface winds out of the 
northeast at 8 to 10 knots will veer to the northeast to east by 
this evening, increasing to 10 to 12 knots with occasional gusts 
near 18 knots.

.CLIMATE...
On this day in 2009, both the daily record cold high temperature 
(64F) and the record low temperature (49F) were recorded in 
Marathon. Temperature records in February date back to 1951.
