Update
Morning sounding data and analyses of water vapor and precipitable
water data show that south florida currently sits under a pocket
of relatively drier air associated with mid level ridge extending
west to east across the area. To the north is an area of higher
moisture over central florida associated with a trough just to the
north, and to the south is deeper moisture over the straits of
florida along a weak and nearly stationary low-level trough.

Short-term model guidance suggests that the trough across
central north florida will nudge southward this afternoon,
potentially leading to a slight moisture increase across south
florida as the day progresses. Overall wind flow is light across
the area with weak southerly flow already overtaken by east coast
sea breeze late this morning, with the gulf sea breezes to follow
shortly after noon. Short-range high-resolution models indicate a
slightly more convectively-active east coast seabreeze this
afternoon with a slow n-ne storm motion. Current depiction of pops
for this afternoon generally follow this pattern of highest rain
chances from palm beach county south into interior broward and
miami-dade counties and will not make changes at this time. Last
few hourly runs of the hrrr model suggest a higher chance of
precip over parts of the mia fll area compared to forecast pops,
so will monitor these trends closely. Hi-res guidance conversely
shows little in the way of precip around and west of lake
okeechobee as well as over interior collier county where forecast
pops are in the 30-40% range this afternoon. Will not make any
changes in these areas despite this guidance, as general pattern
supports at least a few showers thunderstorms developing along the
advancing gulf sea breeze. Low pops along the gulf coast is
generally supported by model guidance and trends.

Weak mid-level lapse rates and lack of strong forcing suggests
that storms today will be primarily below advisory levels.

Temperatures and wind also look on track for this afternoon.

aviation...

with more of a southeast flow today, both the gulf and atlantic
sea breezes should be able to form today. This should push most of
whatever convective activity forms, to the interior. This should
limit the impact at the TAF sites. Current hi-res models are
showing limited activity today as well, so have removed TS from
the tafs and left vcsh for now. Otherwise,VFR conditions should
prevail through the day.

discussion...

today and tonight...

mid to upper ridging will remain prominent from the eastern gulf of
mexico into the western atlantic, as upstream troughing dips into
northern florida and offshore of the carolinas. At the surface, a
somewhat diffuse frontal zone will meander about the lower gulf
coast states as western atlantic ridging continues to dominate
our weather locally. Moisture channel imagery, streamline
analysis, and the GOES total precipitable water product all
indicate that drier air is filtering into southeast florida, while
deeper moisture pools to our north ahead of the aforementioned
frontal zone. The combination of warm temperatures aloft and
subsidence from the deep layer ridge suggests a general
suppression of shower and thunderstorm coverage for today, and
this is consistent with output from the convection allowing
mesoscale models, which show only scattered sea breeze driven
convection over mainly interior and west coast areas for this
afternoon. Expect showers and storms to end this evening over land
areas, while perhaps lingering a bit longer over the gulf waters.

High temperatures have been running a bit over the blended model
guidance, particularly across interior and western portions of the
area, and will go with a persistence forecast for temperatures,
with maximums in the lower to mid 90s for the west, and upper 80s
to lower 90s elsewhere.

Thursday and Friday...

ridging aloft will begin to break down on Thursday, as offshore
troughing evolves into a closed low over the bahamas Thursday night.

The low will slowly trek westward across south florida on Friday,
bringing an increase in moisture and upper level winds. This,
combined with cooling 500 mb temperatures to around -10 celsius,
suggests more widespread showers and thunderstorms on Friday, with a
few stronger storms possible. Temperatures should be near, to
perhaps slightly below, normal with more cloud cover and greater
thunderstorm coverage on Friday.

Saturday through Tuesday...

the upper low will be off to our west by Saturday afternoon, however
a few residual perturbations will pass through, and deep moisture
should remain in place through at least Sunday. Drier air will
filter in thereafter, with lesser shower and thunderstorm coverage
expected by early next week. Look for temperatures to remain near
seasonal normals.

Marine...

prevailing east to southeast winds will continue for the atlantic
and gulf waters, with wave heights averaging 3 feet or less. Scattered
showers and thunderstorms will occur across the atlantic and gulf waters
mainly during the overnight and early morning hours, before
shifting primarily to the gulf waters during the afternoon. Winds
and waves could be locally higher in and around any shower or
thunderstorm.
