Discussion
Shower activity has proliferated across the eastern half of the
service area this morning, although only a few lightning strikes
have been detected, and showers have decreased across the waters
west and southwest of key west. The showers are moving steadily to
the northwest, embedded within moderate deep SE flow as depicted
by kbyx VWP data. Skies are partly to mostly cloudy along the
island chain, with temperatures rising slowly through the lower to
mid 80s, and winds on land generally from the southeast at 10 to
15 mph.

Surface analysis depicts high pressure centered over the western
atlantic, with a ridge extending westward into the southeastern
states. The keys lie within a moderate pressure gradient along the
southwestern flank of this ridge. Aloft, a poorly defined mid-
level weakness persists from the southwestern atlantic across
south florida and down into the bay of campeche. Infrared
satellite imagery shows widespread layered cloudiness and clusters
of convection along this weakness, while GOES tpw imagery depicts
a very moist airmass in place across our region, with estimated
pw values in excess of 2 inches. The 12z key west and miami
soundings confirmed this moist airmass, with measured pw just over
2 inches or above the 90th percentile for this date. The
soundings also found some moderately dry layers in the 850-700 mb
layer, although this dryness does not appear to be inhibiting
shower development over the region.

For the rest of today, model guidance suggests that the current
moderate SE low level flow will back to ese or even E and weaken
briefly during the afternoon. It appears unlikely that the flow
will weaken and back sufficiently or for a long enough time period
to allow for good cloud line development along the lower keys as
we have seen the past few days, and this flow regime should keep
mainland convection and associated outflows mainly north of the
keys. Therefore, with decreasing flow and no obvious mesoscale
triggers in store, would expect shower activity to decrease
somewhat during the afternoon, although there is still sufficient
deep moisture and instability aloft present so that scattered
showers and storms will probably continue. Have updated the
forecasts to show the highest rain chances during the rest of the
morning, backing off a bit to high chance pops this afternoon.

Marine
Morning observations from along the reef and in the gulf waters
show generally SE winds in the 10 to 15 knot range, while a recent
ship report came in with SE winds at 14 knots over the straits.

Expect winds to back to the ese and decrease somewhat this
afternoon, although locally higher winds and seas will be
possible in and near convection and associated outflow boundaries.

Only minor adjustments to first period weather and transition
wording are expected for the late morning forecast issuance.

Aviation
A wet pattern in place for at least this morning into early
afternoon. There will be a chance for brief round of MVFR
conditions, diminishing through the afternoon. Surface winds will
continue to lull early this afternoon, dropping to 5 to 10 knots.

Winds will then pick up again this evening back to 10 to 15 knots
and gusty.

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.
