Discussion In the middle and upper levels(700-200 mb), latest
available satellite imagery overlaid with model streamline
analysis as of 200 pm depicts deep low amplitude troughing
encompassing much of the western CONUS this afternoon. Downstream
of that, a building 590 mb plus ridge continues to intensify
over the western caribbean sea near the cayman islands, with an
attendant expansive east and west oriented ridge extending from
southern mexico east northeast to across the southern bahamas.

South florida and the florida keys are beneath the northern
periphery of this anticyclone.

At the surface and in the lower to middle levels,(surface to 700
mb), latest available land and marine surface observations and
analysis as of 200 pm, details a stationary front extending from
southern georgia west southwest to near houston. South of that,
the westernmost periphery of an anticyclonic ridge crosses south
florida from the central atlantic ocean.

Currently As of 200 pm, skies across the islands and all waters
are sunny. Temperatures have reached between 80 and 85 degrees
across the florida keys island chain, with dewpoints in the upper
60s to lower 70s. C-man stations along the florida reef are
southeast to south between 10 and 15 knots and gusty, with island
platforms at 10 to 15 mph and gusty.

Short term Tonight thru Friday, large scale models continue to
maintain the center of an expansive near 590 dm plus anticyclone
positioned across south florida, the southeastern gulf of mexico,
cuba, the NW caribbean sea, which includes the florida keys.

Surface ridging now extending across the florida peninsula from
the central tropical atlantic will remain in place until Tuesday.

At that point, stronger ridging over the northeastern united
states will build in, resulting in a bit of a tighter mslp
gradient, more typical of mid-late february.

Given that winds will remain east southeast or southeast through
the period, with slightly elevated moisture right near the
surface, expect late night early morning convergence to support a
few showers. For tonight latest hrrr and WRF detected a few
showers developing later due to some weak upglide, but guidance
numbers have decreased a bit from earlier overnight runs, so will
keep just a dime pop in for the overnight period, with dime pops
thereafter this week, or for washingtons birthday through Friday.

High temperatures will reach 80 to 85 degrees and lows will only
fall into the lower to mid 70s thru the week.

Extended Friday night through Sunday, still see near 590 dm
ridging in the area, with heights possibly falling late in the
weekend, but surface ridging just to the north will continue to
keep southeast winds with above normal temperatures continuing and
slight chances for showers. Will carry mid 80s and mid 70s, as
waters warm up by that point.

Marine Scec will be in place again tonight across the florida
straits for increasing winds again. Scec will be in place across
the straits Monday night and Tuesday, with SCA in place across the
straits Tuesday night thru Wednesday night, when scec for place
hawk channel and the offshore gulf waters Tuesday night and
Wednesday. No headlines in place ATTM for Thursday and Friday.

Aviation Vfr conditions expected at both keyw and kmth island
terminals tonight. Just a few to scattered clouds expected with
bases at fl020-025 & fl050-060 respectively. Winds will average
aoa 7 to 11 knots from between 140 and 170 degrees.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
