What's New / NOTES
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 tonight)
issued at 359 am cdt Sat may 25 2019
a decaying MCS was slowly moving into the western part of the cwa
early this morning. This feature has made glacially slow progress
over the last 6 hours, and both satellite and radar have shown
weakening trends with time. Pops have been lowered across the
western and northern CWA to account for this weakening trend.

Outflow boundaries may provide a focus for shra tsra this
afternoon and evening, but more widespread rain will probably not
occur until after 00-03z. By that time, a disturbance lifting out
of a trough to the west as well as moisture convergence along the
nose of a strengthening h85 LLJ will support development of a
thunderstorm complex over eastern ks. The resulting area of
precipitation is expected to bring shra tsra to the northern half
of the lsx CWA after 06z. Isolated strong to severe storms will be
possible due to 30+ kts of 0-6 km shear and sufficient cape, even
after sunset.

Highs today will range from the lower 80s in NE mo to the upper
80s in SE mo and SW il. This is above normal for late may.

Long term (Sunday through Friday)
issued at 359 am cdt Sat may 25 2019
active weather is expected to persist through the early middle
part of the upcoming week. The lsx CWA is located along the
periphery of a subtropical ridge over the southeastern conus,
leading to a "ring of fire" convection pattern when PV anomalies
lift northeastward out of a trough over the western conus. This
active weather pattern is expected to remain in place until the
early middle part of the upcoming week when a strong PV anomaly
finally lifts northeastward and phases with a much larger closed
low which dips southeastward out of canada. The resulting upper
air pattern will be weakly northwesterly to quasizonal across the
lsx CWA by the end of the week and may even bring a day or two of
dry weather to the region.

There will be a couple of opportunities for strong to severe
thunderstorms based on the forecast CAPE shear profiles. In
particular, the northern half of the lsx CWA could see strong to
severe storms on Monday Monday night and the northwestern half of
the CWA could see strong severe storms on Tuesday Tuesday night.

At this time, there appears to be more shear (around 40 kts of 0-6
km shear), higher CAPE (at least 1000-1500 j kg), and stronger
dynamics for Tue tue night compared to Mon mon night.

Temperatures will remain above normal through Tuesday with highs
in the mid upper 80s and lows in the 60s to near 70 across most
of the area. By Wednesday, a cold front will be moving through the
region and temperatures will return closer to average values.

Aviation (for the 12z tafs through 12z Sunday morning)
issued at 617 am cdt Sat may 25 2019
vfr conditions are expected for the majority of the TAF period at
all terminals. The exception may be after 26 00z when an area of
showers and thunderstorms develops to the west and then moves
towards the terminals. Shra tsra should reach kcou kuin around
26 03z and kstl ksus kcps after 26 07z. A stray shra tsra cannot
be ruled out beforehand, but the expected sparse coverage
precludes a mention in the tafs at this time. Winds will remain
southerly to southwesterly.

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.
