Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

area forecast discussion
national weather service wilmington oh
1045 am edt Wed sep 20 2017
A weak upper level disturbance will move through the area,
offering a few lingering showers and thunderstorms today. Drier
conditions are expected for the end of the week into the weekend
as upper level ridging builds into the ohio valley. Warm
temperatures will continue into the upcoming weekend.
Near term until 6 pm this evening
With the kiln sounding measuring a precipitable water amount of
1.53 inches -- roughly 90th percentile for mid-september -- the
area remains in a moist and somewhat stagnant section of the
weather pattern. Fog and copious mid clouds (600mb) have existed
around the area so far today. Though this has held temperatures
back slightly from the previous forecast, once the Sun is out
the current high temperatures in the forecast will still likely
be reached. Precipitation chances are tough to pin down, with
just a weak shortwave moving through the area this afternoon,
and no obvious signs of near-surface convergence. With a few
showers already on the radar pops had to be increased slightly
through the next few hours, but a 20 (or 30 at most) percent
chances will likely be enough cover the afternoon.
Previous discussion >
quick update to allow the dense fog advisory to expire, but to
continue an sps mention of fog for the next hour or two, as the
areal extent of the dense fog has has diminished to an extent.
A few sites (especially in a hamilton warren clinton county
cluster) remain at 1 4sm but satellite imagery suggests most of
the thicker low-level moisture is confined to river valley
Previous discussion >
visibilites seemed to be crashing south of the mid level cloud
desk, so issued a dense fog advisory until 9 am. Mositure seemed
shallow enough to only issue it until 9 am, as the fog will
hopefully begin to burn off quickly.
Early morning discussion>>>
weak mid level low over central ohio
to continue to weaken and open up as ridging builds into the
west. This feature combined with marginal instability may lead
to a few showers and perhaps a thunderstorm. Have limited pops
to very low chance slight chance over iln S eastern counties. An
precipitation that develops will diminish by mid to late
afternoon as the mid level ridge builds into the west.
Latest satl imagery shows that clearing has taken place over
iln S southern counties. With a fair amount of lingering low
level moisture, and light winds, areas of fog have developed
mainly in river valleys. Will issue an sps for reduced
visibility due to the fog.
Expect the fog to improve quickly this morning with partly
cloudy conditions developing. Warm temperatures to continue with
highs from near 80 northeast to the mid 80s southwest.
Short term 6 pm this evening through 6 pm Thursday
Mid level ridge to build into the great lakes through the
end of the week. Expect clouds to diminish this evening with|
patchy fog developing overnight. Lows to range from the lower
to middle 60s.
With ridge in place expect general subsidence Thursday. Forecast
soundings show an inversion and with a lack of significant
forcing have opted for a dry forecast. Warm temperatures look to
be around 10 degrees above normal with highs in the mid and
Long term Thursday night through Tuesday
Robust ridge building at the surface and aloft will dictate weather
conditions through the period. Latest models indicate 1020 mb
surface high pressure over new england in conjunction with a 5900
meter 500mb high extending from the gulf coast to southern canada.
The surface high is shown to retrograde under the upper high to the
great lakes and ohio valley by Sunday, with the system then
exhibiting modest height and pressure falls by Tuesday.
This weather regime will be absent of forcing and deep moisture,
with downward motion the rule in the anticyclonic circulation around
the high. Dry weather is expected through the period.
Mostly sunny mostly clear skies will be observed, and temperatures
will be well above normal under anomalously high geopotential
heights. High temperatures reaching the middle and upper 80s Friday
through Monday may slip only a couple degrees to the lower 80s
Tuesday. These temperatures, being close to normal for july, will be
10 to 15 degrees above normal for late september.
Aviation 15z Wednesday through Sunday
Weak mid level S W trof to pivot east of the area today with
ridging to begin building into the west this afternoon. A
few showers or perhaps a thunderstorm is possible over kcmh and
klck into about mid aftn but expected coverage is too limited
to mention in the TAF forecast at this time.
Meanwhile, with good low level moisture present, light winds and
clearing skies, fog has developed across kcvg kluk and kiln.
Early ifr vsbys and CIGS will improve becomingVFR by mid
morning. ExpectVFR conditions through the remainder of the day
into the early evening.
Fog is expected to develop again tonight with skies clearing
this evening. Have MVFR vsby restrictions at kday and kcmh with
ifr conditions at the more fog favored location of kluk kiln
Outlook... No significant weather is expected at this time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
