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.

High pressure will remain across the ohio valley tonight. As
the high moves east tomorrow, warmer air will begin to move into
the region, with an increase in temperatures expected through
the rest of the week. Chances for storms will increase on
Thursday, and especially for Friday and Saturday, as a front
gradually moves into the area.
Near term through Wednesday
The center of an area of surface high pressure is currently
over the middle ohio valley. Winds have either become calm or
light and variable. Mainly clear skies are expected overnight.
Should be enough radiational cooling for some patchy shallow fog
in the southern river valleys. Temperatures will fall into the
upper 40s to the lower 50s by sunrise Wednesday morning.
Short term Wednesday night
By Wednesday morning, the surface high will be centered over the
appalachians of west virginia and virginia, continuing to move
east of the region. The air mass in place over the ohio valley
will be quite dry, with 850mb moisture projections suggesting
that diurnal cumulus clouds may be hard to come by. As ridging
builds into the area, there will eventually be a slight
increase in high clouds. This will do little to stop an obvious
warming trend, as the switch to southerly flow will be
pronounced -- not just at the surface, but with southwesterly
warm advection aloft through the 850mb-700mb layer. Max
temperatures will rebound to values close to normal -- near 80
to lower 80s from northeast to southwest. With the pattern, will
take the higher end of the SREF envelope, and slightly above a
nam GFS model consensus.
Clouds will continue to increase from the NW on Wednesday night,
with some concern for convection to reach the northwestern iln
counties before 12z Thursday morning. This may be mcs-driven and
thus hard to forecast at this point, but the more likely
scenario would be to keep things upstream, and thus only low-end
pops will be kept in the forecast for early Thursday morning.
Long term Thursday through Tuesday |
Summertime pattern will be in place for the long term with high
temperatures in the 80s and low temperatures in the 60s to around
70. Went close to the superblend for temperatures during this time.
Several weak disturbances will work through the region through the
long term period. Again, went close to the superblend for
precipitation chances as well. There is decent instability across
northwestern portions of the forecast area Thursday afternoon into
the early evening hours therefore cannot rule out an isolated strong
to severe storm with damaging wind gusts being the primary threat.
Without any decent forcing limited precipitation chances to the
chance category for the long term except for Monday night. There is
a little better signal during this time and also better model
consistency therefore felt more confident in the higher precipitation
chances during this time.
Aviation 02z Wednesday through Sunday
Surface high pressure will remain across the ohio valley
tonight. Skies will become mainly clear. Light variable to calm
winds can be expected. There will likely be some shallow patchy
river fog at kluk where predominate MVFR tempo ifr visibilities
For Wednesday, winds will shift to the south, and will increase
in strength to around 8-12 knots as the surface high moves east.
Clouds should be limited to some cirrus with perhaps a slight
chance of someVFR cumulus development.

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.
