Mid to upper level ridging over the eastern United States supports
an impressive anticyclone centered over the extreme western North
Atlantic. East to southeast breezes have freshened, agitating the
land-side palm trees, and supporting sustained winds around 17
knots along the Reef tract, gusts frequently have reached 25 
knots. Temperatures are near 80 with dewpoints approaching 70. 
Rain chances today are 20 percent, with rain chances increasing to
60 percent tonight. The forecast is on track and needs no 


Small Craft Advisory in effect for the Straits of Florida due to
east to southeast winds near 20 knots and seas as high as 7 feet.
Small Craft Advisories likely will be required tonight for all
coastal waters of the Florida Keys. From synopsis, a ridge of 
high pressure will extend across the Southeastern United States 
today through Thursday night. This ridge will begin to shift 
southward Friday and Friday night. Breezes may begin to diminish
Saturday or Sunday. 


VFR and gusty east to southeast breezes will prevail this
afternoon at the EYW and MTH terminals. Recent radar trends
indicate less chances for brief MVFR encounters, as shower
coverage has decreased. However, upstream satellite derived
moisture products and forecast soundings indicate rain chances
returning to the terminals overnight. We have included TEMPO MVFR
episodes in the TAFs, which may need to be extended towards 12Z. 


GM...Small Craft Advisory for GMZ052>055-072>075.
