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.

Short term (through late Saturday afternoon)
issued at 344 pm cdt Fri jun 22 2018
the stacked low pressure system continues to push eastward this
afternoon. As it moves out of the area, expect zonal flow over
the area on Saturday. The effective sfc boundary shud be well
south of the area, but is expected to lift north during the day.
Believe much of the day will be dry, but with the front lifting
northward and at least modest afternoon instability, kept small
pops going. Saturday will be a bit warmer than today, with highs
pushing into the lower 80s.
Long term (Saturday night through next Friday)
issued at 344 pm cdt Fri jun 22 2018
main focus shud be as the wrmfnt lifts thru the area Sat night
ahead of an approaching low. This activity shud continue into mon
morning. With small differences in timing, have kept pops lower
for now. The threat for storms continues thru Wed until a cdfnt
drops thru the region.
This fnt shud quickly lift northward thru the area. Mdls are similar
to yesterday and suggest fairly strong ridge aloft on thurs and fri.
The GFS continues to suggest lower heights as well as some trof
influence by fri. While the GFS and ECMWF suggest warm temps, the
ecmwf suggests temps just above the century mark with an 850mb temp
of 26c. Have not trended temps this warm, but a warming trend is
apparent in all mdl guidance thru the end of the week.

MVFR CIGS to continue across the region tonight into at least
Saturday morning. The highest concentration of MVFR CIGS is near
uin at this hour, but these CIGS should build southward tonight
into the st. Louis terminals. All sites are likely to remain MVFR
tonight, with fuel-alternate CIGS likely. Can't completely rule
out ifr CIGS near uin, but did not have the confidence to include
those at this time. Also can't completely rule out some light fog,
but given the expansive stratus shield, suspect fog impacts will
be fairly minimal. Otherwise, northwesterly winds this evening
will go fairly light and variable overnight into Saturday morning
as high pressure attempts to nudge into the region.
Specifics for kstl:

Conditions should return toVFR Saturday afternoon as cloud bases
slowly rise with the heating of the day.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
