Short term (today and tonight)
issued at 320 am cdt Mon oct 23 2017
07z 2am surface analysis shows 1010mb low over southeast
illinois... With widespread showers lifting northward across the
eastern half of the kilx cwa. The low will track northeastward
today and will reach southern michigan by 00z 7pm. Most models
show deformation zone precip associated with the low persisting
across east-central and southeast illinois for much of the day,
with areas along west of the i-55 corridor gradually drying out
by midday. High temperatures today will range from around 60
degrees along the indiana border... To the middle 60s across the
southwest CWA around jacksonville and springfield.

A short-wave trough currently evident on water vapor imagery over
the northern plains will dive southeastward later today,
providing the necessary kick to eject a closed upper low over the
ozarks northeastward. As the trough approaches and amplifies,
scattered showers will develop along northwest of the illinois
river late this afternoon... Then will spread across the remainder
of the area and become more widespread tonight. Have carried
likely pops along north of a canton... To lincoln... To paris line
accordingly. Low temperatures tonight will drop into the lower to
middle 40s.

Long term (Tuesday through Sunday)
issued at 320 am cdt Mon oct 23 2017
Tuesday will be a cool showery day as the upper wave digs into the
region. Likely to categorical pops are warranted, with high
temperatures remaining in the 40s. As the wave begins to depart,
the showers will end and skies will clear from west to east
Tuesday night. While low temperatures are expected to drop into
the lower to middle 30s, think W NW winds of 8-10mph will prevent
frost formation.

A series of short waves will drop southeastward out of canada,
re-enforcing the mean upper trough in place over the great
lakes midwest through the remainder of the extended. Heights will
temporarily rise in advance of the next significant wave expected
to arrive at the end of the week, allowing high temperatures to
climb well into the 60s on Thursday. As the wave approaches, a
cold front will sweep through illinois Thursday night into Friday
morning, but will be devoid of precip due to an initially dry
airmass. As stronger upper support arrives, a few showers will
develop along behind the departing front Friday afternoon and
evening... Mainly east of the i-57 corridor.

Main concern later in the period will be forecasting a potential
frost freeze over the weekend. 00z oct 23 models have come into
much better agreement concerning the timing of the Friday
wave... But some minor discrepancies still exist for another
short-wave expected Saturday night Sunday. The GFS is considerably
stronger with this feature, resulting in lower heights and colder
temperatures. Meanwhile the ECMWF is slightly weaker and further
north and therefore not quite as cold. ECMWF numeric guidance
suggests lows around 30 degrees both Friday and Saturday
night... While the mex shows even colder readings down into the
middle 20s. At this point, will play it conservatively and
forecast lows in the lower to middle 30s Friday night... Then the
upper 20s to around 30 degrees Saturday night. These numbers will
be fine-tuned with later forecasts... And frost freeze headlines
may eventually be needed as well.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 556 am cdt Mon oct 23 2017
ifr ceilings persist along east of a kbmi to kdec line early this
morning... With forecast soundings suggesting only a gradual
improvement toward midday. Have raised ceilings to MVFR at kbmi by
13z and at kdec by 14z. Further east, have lingered showers and
ifr ceilings at kcmi through 19z. After a period ofVFR ceilings
this afternoon, lower clouds will once again return tonight as an
upper disturbance approaches from the northwest. Have introduced
MVFR ceilings and vcsh at kpia after 06z... Then further east to
kcmi after 08z.

Ilx watches warnings advisories
None.

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.
