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.

Update to aviation forecast discussion...
Short term (this evening through Thursday)
issued at 244 pm cdt Wed jun 20 2018
the main synoptic cold front has passed east of the area sweeping
the deeper gulf moisture east. The area remains in a somewhat
unstable airmass this afternoon ahead of the next front that is
now located across nebraska closer to the developing upper low.
Around 1000 j kg of MLCAPE will be present this afternoon into the
evening which could be sufficient for scattered showers and
t-storms through sunset. Effective shear will increase to around
30kts and the unidirectional wind profile suggests any organized
convection may be capable of producing gusty winds but at this
point coverage would appear to be isolated.
Once the diurnal storms diminish it should be mostly dry overnight
before more showers invade the area from the north as the upper
low deepens and drifts southward with time on Thursday. The center
of the upper low should remain across mo placing the CWA in the
western side of the circulation with some rain showers and breezy
conds expected during the day especially north of i-70. Highs will
be cooler than normal for a change with daytime temps in the 70s.
Long term (Thursday night through Wednesday)
issued at 244 pm cdt Wed jun 20 2018
the low will depart the area Thursday night leaving the area in
quiet weather for a short time at least through Friday. The next|
shortwave in the northwest flow regime will approach the area
Friday night. The 805mb WAA thetae advection will be focused
across southern ks where an MCS will likely form. We will be on
the northern side of any complex and will keep modest precip chcs
going for Friday night mainly across the southwest half of the
A second shortwave will move across NE ia on Saturday and will
keep at least some chance for t-storms across the area sat-sat
night although confidence in timing and location of any convection
during the sat-sat night time frame is very low at this point.
There is higher confidence in the upper pattern by early next week
as another upper low emerges into the plains. Given the moisture
and shear profiles this could bring us our next shot of more
widespread severe weather potential sometime Monday into Tuesday.
Aviation (for the 06z tafs through 06z Thursday night)
issued at 1149 pm cdt Wed jun 20 2018
for the 06z tafs,VFR now that storms have move east of all
terminals. Will begin to see wrap around clouds but uncertain how
much in the way of showers will work into the terminals as best
chances may remain north and northeast of the terminals. MVFR cigs
should work into the area, however, and will possibly stay for
much of the forecast period after 12z.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
