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 Wednesday afternoon)
issued at 322 pm cdt Tue oct 16 2018
a weak cold front is expected to move through the bi-state area
tonight. No precipitation is expected with this frontal passage due
to low moisture content and meager low-level ascent. Outside of some
cirrus, most of the region should expect another clear night with
low temperatures dropping into the mid 30s to low 40s. Leaned at or
below cooler met guidance for minimum temperatures tonight because
of favorable conditions for radiational cooling.
Another cool autumn day is on tap for Wednesday along with a sunny
sky. High temperatures are expected to range from the mid 50s to low
60s from north to south. For reference, these readings would be
about 10 degrees below normal for the 17th of october.
Long term (Wednesday night through next Tuesday)
issued at 322 pm cdt Tue oct 16 2018
surface high pressure center is forecast to move southeastward
across the CWA late Wednesday night. This high will help provide
very favorable conditions for radiational cooling overnight due
to light variable winds beneath a clear sky. While a freeze does
not appear likely, scattered to widespread frost will likely occur
with lows in the 30s. Speaking of frost, will only be mentioning
in areas that did not observe either widespread frost or a hard
freeze this morning. This includes portions of southeast missouri
and southwest illinois.
Temperatures should remain about 5-10 degrees below normal through
the remainder of the week and into next weekend. The next chance of
rain begins on Thursday night and continues into the day on Friday
ahead of the next approaching cold front. At this juncture, the best
chances of rain appear to be across portions of southeast missouri
and southwest illinois where strongest low-level warm moist
advection and mid upper level ascent should reside.
There is still a strong signal that a potent upper-level trough will
carve out across the eastern third of the CONUS late this weekend.
Specifics with respect to exact strength and longitudinal placement
of this trough axis will have a big impact on temperatures across
our neck of the woods. It does appear that continued below normal
temperatures are favored regardless Saturday night and Sunday, but
exactly how cold is the question. If the aforementioned digging
upper-level trough is stronger and or slightly further to the
southwest, a freeze would certainly be on the table for those areas
that did not observe a freeze this morning. Timing of surface high
would also be of critical importance.
A quick rebound in temperatures on Monday is likely ahead of the
next cold front. High temperatures well into the 60s for many areas
is likely, which would be actually very close to normal for a
change. Behind the cold front, temperatures for next Tuesday look to
be back below normal.
Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 605 pm cdt Tue oct 16 2018
vfr and dry conditions expected thru the TAF period. A cdfnt will
push thru the region late tonight into Wed morning, with swly
winds becoming nwly to nly behind the fnt. Steam fog may develop
late tonight and may impact ksus and possibly kcps. Confidence is
too low to add to current taf.
Specifics for kstl:VFR and dry thru the period. A cdfnt will push
south thru the area late tonight bringing swly winds to nwly
behind the fnt.

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.
