Update
Shower and thunderstorm activity continues to decrease in coverage
at this hour across the tri-state region. Any additional
development is expected to remain isolated and weak in nature this
evening. Light patchy fog will be possible overnight, especially
in areas that received rainfall this afternoon this evening.

Overnight lows in the mid 70s are expected.

Prev discussion [743 pm edt]
Near term [through tonight]
18 utc radar satellite imagery show scattered showers and
thunderstorms developing across the region. With overall flow
being northerly around 10-15 kts, best storm growth so far has
been along the sea breeze fronts. As these boundaries move inland,
expect additional storm growth through 22z. Storms should
dissipate after sunset with a quiet night expected across the
region with lows in the mid to upper 70s. Isolated storms are
expected to develop over the coastal waters prior to sunrise, but
remain far enough offshore.

Short term [Friday through Saturday night]
An upper low will move west across the northern gulf coast atop
mid and low-level ridging through Friday night. While the low may
provide a bit of synoptic ascent early on Friday, convection on
both Friday and Saturday should be dominated by the seabreeze
fronts. While there will be some dry air present in the mid-
levels, it won't be as dry as this afternoon where a widespread
scattering of storms has been able to develop. Thus have stuck
very close to climatology with pops. In fact, the presence of a
reduced amount of dry air may slightly increase the wet microburst
potential both Friday and Saturday. Due to the ridge breaking down
a bit with the passage of the upper low and an expected earlier
start to convection, highs may be a couple degrees lower than
today. Expect highs to still remain in the lower to middle 90s,
with heat indices in the low 100s.

Long term [Sunday through Thursday]
A shortwave will move through the great lakes and northeast
through mid-week, amplifying a trough into the mid-atlantic by
Tuesday. While the associated cold front will remain well to our
north, surface troughing associated with the shortwave and lee
effects is expected to run down the eastern seaboard into central
georgia. Wnw steering flow may push convection that develops
along the trough into the tri-state region both Monday and
Tuesday. Pops will be above normal to start the week, with more
typical seabreeze storms by mid-week to finish the period. Highs
will be near normal, in the lower 90s, each day.

Aviation [through 00z Saturday]
Isolated showers could develop near aby and possibly dhn this
evening through sunset as the sea breeze continues to move
inland, but otherwise showers and thunderstorms should continue to
diminish in coverage across our area before dissipating later
this evening. Scattered showers and thunderstorms are possible
late tomorrow afternoon into the early evening, but chances appear
fairly low at this time. Tlh and vld appear to have the highest
chances of seeing a shower thunderstorm at this time.

Marine
Relatively light winds and low seas will prevail for the next
several days, with the best chance of rain between midnight and
noon each day.

Fire weather
Low dispersions will be possible across portions of the tri-state
region once again Friday. Otherwise, there are no fire weather
concerns.

Hydrology
Typical scattered summertime storms are not expected to cause any
flooding issues over the next several days.

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.
