What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (through late Friday afternoon)
issued at 259 pm cdt Thu sep 21 2017
early this afternoon, a sharp upper level ridge axis extended from
near detroit, michigan to northern arkansas. This has effectively
trapped an area of thick convective debris clouds (from a MCS early
this morning in southeastern ia that backbuilt some into northeast
mo) between stl metro and the quad cities to the north where there
is very weak steering flow. Consequently, this area of thick
cloudiness has kept temps mainly in the 80s this afternoon, while
surrounding areas have mostly reached into the low to mid 90s. A
surface outflow boundary from this morning's convection extends from
near kirksville, mo thru the far southwestern edges of stl metro and
into southern il, with easterly winds behind it, and southerly winds
ahead of it. While the cumulus that has developed along this has
been more vertically developed than the rest to the south, it still
has struggled (for now) to develop enough to warrant concern for
pcpn.

It may still be possible to pop an isolated shower or storm along
the outflow just W or S of stl metro thru sunset, but looks unlikely
at this time.

The area of thick convective debris clouds will be slow to exit and
thin tonight but should eventually as they edge slowly east into il
toward midnight. Otherwise and elsewhere, skies will clear around
sunset. Some patchy fog is expected mainly S and E of stl metro
closer to the surface ridge, where lighter wind flow and higher
crossover temps are anticipated. MOS min temps, which are similar
to persistence, look good and could spell record high mins at stl
and possibly uin--see climate section below.

The upper ridge axis will move little by Friday afternoon,
keeping high thicknesses in place, with southerly flow expected
during the daytime Friday. Lack of a MCS to the north to generate a
new round of convective debris clouds to interfere with the heat
should mean a significantly warmer day tomorrow in spots, with max
temps surging into the 90s. Record MAX temps could be threatened,
particularly at stl. See climate section below. Heat index values
are also expected to top out around 100, especially in what are
typically warmer temps in stl metro.

Long term (Friday night through next Thursday)
issued at 259 pm cdt Thu sep 21 2017
the upper level ridge will continue to bring unseasonably warm to
hot conditions to the region through the weekend. A gradual cooling
trend will ensue early next week as heights fall with the main ridge
axis heading east as a deep trof approaches from the west. Could be
some diurnal convection that develops as early as Sunday afternoon
across the eastern ozarks, but the best chance of precipitation will
be associated with the cold front and trof passage Tuesday and
Wednesday. After a hot weekend with high temperatures in the lower
to middle 90s, 70s by midweek will feel like a true taste of fall.

Cvking

Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 1244 pm cdt Thu sep 21 2017
vfr conditions, dry wx, and light southerly surface winds will
prevail at the TAF sites for much of the valid period. Exceptions
to the wind will be areas for much of the stl metro and uin which
are behind a convective outflow boundary with easterly winds and
this will persist for a few hours more before finally reverting
back to more southerly. Another potential issue is vsby reductions
to fog at sus and cps and have included a minor reduction for now
until a better handle can be obtained for the 00z set, such as
observed crossover temps.

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.
