Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

The aviation section has been updated below.
Issued at 239 am edt Sat jun 23 2018
a slowly departing area of low pressure along with some upper
disturbances will keep chances for rain across all or parts of
central indiana this weekend. A frontal system will then bring more
rain chances through next week. Temperatures will gradually warm to
above normal readings by early next week.
Near term today
Issued at 1021 am edt Sat jun 23 2018
rain showers continue to develop across central indiana this
morning. Expect this activity to continue into the afternoon and
early evening. Thus, continued with isolated shower chances and
the potential for isolated thunder later this afternoon and early
evening. The previous discussion follows...

early this morning an upper level low was across northern
indiana. The surface low was across northwest ohio, with a trough
extending back into central indiana. Showers were just north of
Although no showers were across central indiana at the moment, have
seen some pop up quickly and disappear quickly as well. With the
surface trough in the area, can't completely rule out an isolated
shower through the morning hours at any location. Thus will go
slight chance pops all areas, but most places will remain dry.
The surface trough remains in the area this afternoon, and some
heating will increase the instability. Will go low chance category
pops far north closer to the upper low and slight chance pops
elsewhere. However, feel most areas will remain dry again.
Low clouds and patchy fog were spreading across the area early this
morning, and the clouds will likely hang around through the morning.
Some breaks will occur though, especially this afternoon.
The clouds will keep temperatures below normal again today. The
model blend captures this well and will use for high temperatures.
Short term (tonight through Monday night)
issued at 239 am edt Sat jun 23 2018
models are close enough that the model blend initialization
was accepted for most items.
With the surface trough still around this evening and some weak
instability, kept slight chance pops around during the early
evening. After some dry hours, a weak upper level disturbance could
bring some rain to far southern areas overnight. Went with some low|
Another upper disturbance could bring some isolated convection to
the southern third or so of central indiana on Sunday. Slight chance
pops should cover that.
Sunday night through Monday night a warm front will begin its trek
toward central indiana from the southwest. Warm advection ahead of
the front will bring some forcing. The NAM looks to suffer some
convective feedback issues, but other models are also indicating
some rain from this.
Will go with some pops with this featuring Sunday night through
Monday night, with highest pops overnight Monday night when forcing
is maximized. Not confident to go any higher than chance category
pops, so removed anything higher from the model initialization.
The initialization's temperatures look reasonable given expected
Long term (Tuesday through Friday)
Issued at 149 am edt Sat jun 23 2018
confidence is high the period will be warm and humid, with a
persistent chance for rain.
The GFS and european models are in good agreement strong high
pressure--the so-called bermuda high--will develop over the
southeast usa. This will bring air from the gulf to indiana.
With a large, well-defined system dominating the weather, the
consensus forecast should work well. Possible errors are 3 degrees
or less for temperatures and 10 percent or less for pops.
Aviation discussion for the 23 1800z TAF issuance
Issued at 128 pm edt Sat jun 23 2018
both MVFR andVFR conditions persist at the beginning of the
timeframe. Currently expect ind to be the next to scatter its MVFR
ceilings by 1900z or so based on upstream trends. Laf is expected
to hold their MVFR conditions longer than the rest of the sites.
I would not be surprised if they hold ceilings under 3000 feet
past the forecasted 2000z scattering of the deck. Removed the vcsh
as any remaining showers are few and far between and not
confident that any impactful convection will occur.VFR
conditions are then expected overnight tonight into tomorrow.
Expect westerly winds to become light overnight... Remaining light
and veering to the northwest to north tomorrow.

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.
