Short term (through late tonight)
issued at 335 am cdt Sun jul 22 2018
a stacked low pressure system over the ohio valley will remain in
place today tonight while interacting with a separate PV anomaly.

The resulting interaction leads to the upper low becoming elongated
later tonight while deepening the trough over the eastern conus.

At the surface, winds will retain a northerly component
today tonight, although the direction will vary between
northwesterly and northeasterly as the stacked system's surface low
drifts southeastward and a surface ridge extends into the plains.

This will maintain the existing cooler and drier air mass over mo il
today, and today's highs and lows will be very similar to yesterday.

Also similar to yesterday, cloudiness on the western periphery of
the stacked low pressure system will limit insolation across parts
of southwestern il, and cyclonic flow aloft as well as the
occasional PV anomaly rotating around the upper low could produce
scattered diurnal showers (and perhaps an isolated
thunderstorm) across parts of the eastern cwa.

Long term (Monday through Saturday)
issued at 335 am cdt Sun jul 22 2018
a northwest flow aloft pattern will prevail across our region and
much of the central CONUS in general for this entire period. This
will also encourage intrusions of cooler air to drop down on a
regular basis and maintain keeping the above average temperatures
away from our region. In fact, the model forecasts maintain a
northerly or easterly wind thru the entirety of this period in the
middle of a season which typically features a steady diet of south
or southwest winds. We should see MAX temps linger in the 80s each
day with an occasional bump to around 90 degrees on a day or two.

Regarding rain chances, they look pretty slim until late Thursday.

There is a weak signal for rain on Tuesday but it involves an ill
defined weak frontal boundary and limited moisture given this
stretch we are in. Will keep it dry for now with climo pops at 17%
and the overall scenario being not that good and hold off on any
mentionable pops until later in the week. The higher favorability
for rain should continue into next weekend, but the amount of rain
will depend a lot on where if the front on Thursday stalls and how
much overrunning can occur to the west to move into our region.

Aviation (for the 12z tafs through 12z Monday morning)
issued at 624 am cdt Sun jul 22 2018
specifics for kcou:VFR through the period with northwest winds.

Most of the clouds associated with a low pressure system over the
ohio valley should remain east of the terminal, but some mid high
clouds are expected.

Specifics for kuin: stratocumulus on the back side of a low
pressure system will reach the terminal today. A brief period of
MVFR CIGS is possible during the first 0-4 hours of the TAF period
before cloud bases rise. Initially northwest winds will gradually
veer and become northerly by the end of the TAF period.

Specifics for kstl, ksus, kcps: a fragment of MVFR stratus was
extending towards the st. Louis metro area terminals at taf
issuance. Cloud bases will rise due to diurnal mixing and remain
sct-bkn for most of the day as clouds rotate around the back side
of an upper low. Northwest winds will gradually veer and become
northerly to northeasterly by the end of the TAF period.

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.
