Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Short term (through late Thursday night)
issued at 515 pm cdt Wed may 22 2019
another busy night of severe weather is underway as one supercell
has already developed over northeast mo ahead of a cold front in
in an axis of 1000-2000 j kg mlcape. This same area is overlaid by
effective shear of 70kts and 0-1km shear of 20kts which supports
supercells capable of all hazards. Cams runs have been showing
this scenario all day of supercell structures developing across
northeast and central missouri into west central illinois late
this afternoon that will eventually evolve into a qlcs by mid-late
evening as it moves into east central mo and southwest il by late
evening and overnight. There will continue to be the threat for
severe weather during into the overnight hours before the storms
weaken toward morning.
Have issued a flash flood watch for central missouri where
thunderstorms are expected to last the longest tonight. Given that
pwats will be in the 1.5-2.0" range and soils are saturated, flash
flooding is a definite threat in this region.
The front will stall over southern missouri and illinois tomorrow.
The upper ridge will build over the area at the same time which
will act to limit coverage along the front given that amount of
instability along it. Will continue with a chance of showers and
thunderstorms with only a marginal risk of severe weather given
the instability and shear values. The front will begin to lift
north of the area on Thursday night.
Long term (Friday through next Wednesday)
issued at 515 pm cdt Wed may 22 2019
not much change in thinking to the forecast over the holiday
weekend into next week. Global deterministic models and GEFS still
depict a strong upper high will remain over southeast CONUS at the
same time a mean trough remains over the west into the middle of
next week. A west-east oriented frontal boundary will drop back
down into the CWA on Friday and Saturday which will act as a focus|
for shower and thunderstorm development, a few of which could be
strong to severe based on strong severe based on the instability
shear forecast parameters. Coverage of thunderstorms into next
week will be determined by the ultimate location of the front and
how much upper ridging will be over the cwa. For now will keep
with above normal temperatures given forecast 850mb temperatures
between 15-20c and a persistent chance of thunderstorms.
Aviation (for the 00z tafs through 00z Thursday evening)
issued at 637 pm cdt Wed may 22 2019
thunderstorms are expected to continue to develop over central
and northeast missouri and west central illinois early this
evening affecting kuin and kcou bringing the threat of wind gusts
of 35kts or greater, hail, and MVFR ifr ceilings and visibilities
in heavy rain. These storms will move east through the evening
and eventually reach the st. Louis area terminals after 06z. The
thunderstorms will move out of all terminals by 12z with dry and
vfr conditions expected thereafter. Mainly dry andVFR conditions
are expected on Thursday except for any showers and thunderstorms
that develop along a stalled front. Coverage will not be high
enough to include in any of the tafs at this time.
Specifics for kstl:
dry andVFR conditions expected through 06z. Then thunderstorms
will move into the terminals with low MVFR ifr ceilings and
visibilities. These conditions are expected to move out of the
terminal by 12z leaving dry andVFR conditions. There is some
potential for additional showers and thunderstorms during the day
on Thursday, but confidence is not high enough to include in the
terminals 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.
