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.

after chilly early morning lows in the upper 20s and lower 30s,
ample sunshine has warmed 15z 10am temperatures well into the
40s. As the pressure gradient tightens ahead of an approaching
trough axis, southwesterly winds will gust to over 20mph at times
this afternoon. The strong southwesterly flow and continued sunny
skies will help boost highs into the middle 50s. Current forecast
is right on track, so no major updates are needed at this time.
Short term (today and tonight)

surface ridge axis extended from the ozarks into southern il this
morning. This brought light to calm winds to the cwa. The northern
edge of a thin cirrus shield has been affecting areas south of
i-72, but enough breaks have occurred to allow temps to fall into
the mid 30s there. Farther north skies have been clear but winds
have been running around 5 mph, preventing maximum cooling. Even
so readings have dropped to around the freezing mark and will
leave current freeze warning and frost advisory in place through
The surface ridge will sink south today, while a weak trough
approaches from the upper midwest. This will tighten the gradient,
and with sunny skies and steep low level lapse rates, southwest wind
gusts around 25 mph will be common through this afternoon. These
factors will push temperatures several degrees warmer than
yesterday, but still several degrees below normal. Lows tonight
will be a few degrees warmer than this morning, and with the
gradient keeping winds above 5 mph, frost should be isolated at

dry and seasonably cold conditions will continue through|
Thursday. 1034 mb high pressure is forecast to settle over central
il by 09z Thursday, setting up ideal radiational cooling. Lows
should be near to a couple degrees cooler than this morning, so
there is a good potential frost and freeze headlines will be
needed once again.
The only chance of precip in the entire forecast will occur on
Friday, as moisture lifts northeast out of a southern plains
disturbance, ahead of an incoming cold front. It still appears
with the speed of the front that the better moisture return will
be suppressed farther south across the ozarks and into the ohio
valley. Thus, slight to low chance pops and low QPF are expected
this far north.
The late Friday frontal passage will usher in a fresh round of
cold advection and keep breezy, cool, and dry conditions in place
through the weekend. Guidance is showing a trend towards at least
a temporary pattern shift early next week, with height rises
suggesting temps could get back towards normal.
Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 1242 pm cdt Tue oct 16 2018
vfr conditions will prevail through the entire 18z TAF period.
Brisk SW winds will gust 18-23kt through the afternoon before
decreasing to less than 10kt by sunset. Winds will gradually veer
to the W NW overnight as a trough axis passes through the region.
Forecast soundings and numeric guidance both suggest that NW winds
will become strong gusty in the wake of the trough Thursday
morning. Have therefore added 20-23kt gusts after 15z accordingly.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
