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.

402 pm edt Fri jul 21 2017
A stalled frontal boundary south of the area will attempt to lift
north as a warm front overnight. Showers and thunderstorms are
expected to track along this boundary on Saturday, eventually
pushing it south of the area Saturday night. A compact upper
level trough will move across the great lakes region on Sunday
with high pressure arriving for the early part of next week.
Near term through Saturday night
Clouds continue to thin except across the far southern tier of
counties where the CU field is starting to thicken. This is in an
area of weak surface convergence left from the morning MCS that
passed to the south. Some instability is present but a cap is in
place above 850mb and think it will be very difficult to get
anything more than a weak shower late this afternoon. Will keep an
isolated mention of a thunderstorms in the forecast across our
southern tier of counties for a few hours. Clouds will trend
towards mostly clear for the first part of the night before
starting to thicken and lower from the west late. Dewpoints
remain in the upper 60s and some patchy fog is possible, mainly
in the east where skies will be clear longer. Lows tonight will
range from the mid to upper 60s east to near 70 in the west.
Attention then turns to convection developing upstream that will
likely reach the area late tonight into Saturday morning. The warm
front will attempt to push north tonight with an MCS tracking east
southeast along the boundary, likely reaching NW ohio between
10-12z. The MCS is expected to be weakening as it moves into the
area but this will be something to monitor with a 45 knot low
level jet feeding into the back side. Training of storms along
the frontal boundary does present a concern for heavy rainfall
with pw values surging into the region. Did not issue a flood
watch but one may still be needed depending on the intensity and
movement of the MCS as it approaches. Trended highs down a few
degrees on Saturday given expected cloud cover and showers.
The most likely scenario on Saturday is for the MCS with widespread
rainfall to move through in the morning with this limiting
destabilization for part of the afternoon. If lesser amounts of rain
are received in the morning then potential for severe thunderstorms
in the afternoon along the warm front are higher. The whole forecast
area is included in a slight risk of both severe thunderstorms and
excessive rainfall. If robust convection does re-develop Saturday
afternoon evening then damaging wind gusts and large hail will be a
possibility. Given the proximity to the warm front, there could also
be a tornado threat but seems like the less likely scenario.
Whatever convection re-develops along remnant outflow
boundaries or the warm front will tend to favor a
south southeast movement towards the greater instability
reservoir into Saturday night. Thunderstorms will continue to be
efficient rainfall producers until this boundary finally pushes
south of the area late Saturday night.
Short term Sunday through Monday night
Some lingering showers especially in the east on Sunday with
low pressure over eastern lake erie. At this time models not in
good agreement on the exact track and timing of the low so will|
only go with chance pops for Sunday. Secondary trough rotates
across the eastern lakes Sunday night kicking off a few more
showers. True cold front finally pushes across the forecast area
late Monday ushering cooler and drier conditions. Temperatures
for the early part of the work week will actually be a couple of
degrees below normal.
Long term Tuesday through Friday
Cooler and drier conditions for Tuesday as large area of high
pressure moves over the area. High pressure should dominate
enough to keep conditions mainly dry thru wed. Warmer temps and
moisture return for Wed night into Thu while a weak cold front
drifts SE toward the area which could combine to start
triggering a few shra tsra. The threat for shra tsra will
continue for Fri but right now the better chc appears to be for
the SW half of the CWA as the cold front is expected to be into
central oh by then.
Aviation 18z Friday through Wednesday
Vfr conditions will continue through at least 03z with sct-bkn
cu deck near 4k feet clearing with time. Clouds will thicken
with time overnight but enough radiational cooling with moist
ground conditions are present for patchy fog to develop, mainly
at the southeastern terminals after 06z. The forecast beyond
that point depends on the evolution of a larger convective
complex that is expected to develop across the western great
lakes tonight and track into western ohio late tonight. Have
tried to time this into the area with rain and vcts at all
terminals for a window of time late tonight into Saturday
morning. Adjustments to timing and intensity will be needed as
storms approach. Very heavy rainfall is possible and could
result in several hours of ifr conditions Saturday morning.
Outlook... Non-vfr possible Saturday night and Sunday in early
morning fog mist or scattered to numerous showers and
thunderstorms. Non-vfr in early morning fog mist may continue
during the first half of the week.
Warm front across SW ohio will lift NE over the lake overnight.
Thunderstorms complex expected to move along the boundary across the
lake late tonight. Choppy conditions will develop on the lake
Saturday as a low pressure system tracks across the lower lakes. The
exact track of the low still in doubt, so a marginal small craft
advisory is not out of the question. Winds turn back to the west
late Sunday as the low tracks east of the lake. High pressure
finally builds over the lake Monday night.

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.
