Aviation
There could be a few showers around the east coast TAF sites this
morning before an increase in showers and thunderstorms during the
afternoon hours due to the heating of the day. Kapf TAF site
should see the showers and thunderstorms mainly this morning. The
vis and ceiling should remain inVFR conditions, but could fall
down into MVFR or even ifr conditions with the passage of the
showers and thunderstorms.

discussion...

today and tonight...

mid to upper troughing will slowly progress towards the western
bahamas as 15-20 kt of s-sw 850 mb flow brings a continued moisture
feed across southern florida. This flow regime will advect a
broken band of showers and storms originating from cuba north
through our area early this morning with primarily light to
moderate rainfall. With this activity arriving earlier than on
previous nights, a early to mid-morning break in the rain is
possible (as advertised by a consensus of the mesoscale models)
before isolation brings a renewed round of showers and storms
during the afternoon. Given the mentioned 850 mb flow, it appears
that the east coast metro areas will be targeted yet again for the
greater rain chances. Slow storm motions, potential backbuilding,
a deep warm cloud layer, and 850 mb moisture flux convergence all
point towards heavy rain potential. Thus, urban flooding is the
primary weather related hazard for today, given given 24 hour
radar estimated gauge bias corrected rainfall amounts of 1-3". As
such, it shouldn't take much to cause additional issues today
should repeated rainfall rounds impact a particular area.

Secondary concerns for today are lightning and gusty winds which
are possible with any of the taller cores. As the mid upper wave
pulls away later tonight precipitable water values should drop a
bit, with recent model solutions suggesting a bit drier conditions
are expected than with the previous nights. There should be
enough cloud cover and precipitation today to temper afternoon
highs just a bit, although most areas should still be able to
reach the upper 80s in between showers and storms. Overnight lows
will be in the 70s.

Wednesday...

with the mid to upper trough axis located to our east, additional
low amplitude perturbations will continue, with a renewed push of
deeper moisture arriving via ssw low-level flow. At the surface
we'll be under the influence of the western atlantic subtropical
ridge, whose axis will branch west across south florida. Expect a
dominant atlantic sea breeze given this regime, with convective
initiation along it during the late morning to early afternoon
hours. Thunderstorms should have a tendency to drift more towards
the northwest given the steering flow, targeting eastern broward and
palm beach counties with the greatest afternoon evening rain
chances. Of course, all portions of our area will see scattered
showers and storms at a minimum given the coupled deep moisture, low-
level sea breeze forcing, and slightly better than average (for this
time of year) upper support via the passing waves aloft. With the
coverage being more diurnal and scattered in nature, look for a
warming trend to begin (especially for the eastern interior and
metro areas), with highs likely climbing back into the 90s.

Thursday and Friday...

a low pressure system will trek across the eastern 2 3 of the conus,
while a zonally elongated mid-level ridge expands from the northern
caribbean sea into the gulf of mexico. This will support
strengthening surface ridging across south florida with a slight
decrease in tropospheric moisture. Shower and storm coverage should
decrease as a result, while becoming more diurnally driven with
sea breeze collisions as the focusing mechanism. Weak ssw steering
flow should favor the northeast and lake regions for the greatest
late afternoon evening storm coverage. Temperatures should remain
on the warm side, trending towards above normal for portions of
the east coast metro. Maximum heat index values could eclipse 105
degrees for some areas during this time.

Saturday through Monday...

ridging aloft will prevail for much of this period, punctuated by a
wave that should drift from the bahamas towards cuba over the
weekend. Deep layer ridging along with slightly drier conditions
should prevail, with only the typical sea breeze driven convection.

With easterly low-level winds picking up later in this period the
warmest temperatures should shift more towards the interior and
west coast. Near to above normal readings should continue.

Marine...

numerous showers and thunderstorms are likely over the waters today,
with coverage gradually decreasing this week. Lightning, gusty
winds, and waterspouts are all possible, so mariners should exercise
caution. Southerly winds are expected today, with south to southwest
winds prevailing through Friday. Seas will be 3 feet or less.

Aviation...

periods of showers and thunderstorms are expected at each terminal
through the TAF period. Perhaps there could be a bit of a break
later this morning once this line from the south moves through,
with another round of showers thunderstorms late morning into the
afternoon.VFR conditions are expected outside of convection.

Hydrology...

bias corrected radar rainfall estimates indicate 1-3 inches of
rain has fallen on average across much of the east coast metro
areas during the past 24 hours. Periods of showers and storms
producing heavy rainfall appear possible yet again today. Given
somewhat slow storm motions, potential backbuilding, a deep warm
cloud layer, and 850 mb moisture convergence urban street flooding
will again be a concern today. The best time for heavier rain
appears to be from late morning through the late afternoon hours.

Motorists should exercise caution. Remember, never attempt to
drive through flooded roadways.

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.
