Update
Issued at 829 pm cst Tue dec 18 2018
skies mainly clear this evening, though the mid high cloud deck to
our west is near the mississippi river. Temperatures have fallen
off a bit faster so far this evening, but should level off toward
midnight as the clouds increase and winds turn more southerly.

Made some adjustments to the hourly trends for the next few hours,
but overall low temperatures still look on track.

Short term (this evening through Wednesday)
issued at 256 pm cst Tue dec 18 2018
quiet weather will continue tonight into Wednesday as high
pressure drifts toward the east coast. Under clear skies, low
temperatures tonight will range from the upper 20s near the
indiana border to the middle 30s west of the illinois river.

Clouds will be on the increase late tonight, with conditions
becoming overcast during the day Wednesday: however, any light
precip associated with the next approaching system will hold off
until well after dark. Highs on Wednesday will top out in the
upper 40s and lower 50s.

Long term (Wednesday night through Tuesday)
issued at 256 pm cst Tue dec 18 2018
upper low currently evident on latest water vapor imagery over new
mexico and a short-wave across the northern rockies will track
eastward and eventually phase into a significant trough over the
eastern CONUS by the end of the week. The two waves will remain
separate as they pass illinois to the north and south on
Thursday... With phasing occurring further east on Friday. Given
weaker forcing between the two waves, it appears precip will
generally be quite light across central illinois late Wednesday
night through Thursday night before eventually pushing further
eastward into the ohio river valley. The atmosphere will be warm
enough to support mostly light rain: however, a brief rain snow
mix will be possible on the back edge of the precip area Thursday
night into early Friday morning.

Once this system passes to the east, mild dry weather will be on
tap for the weekend with near normal temperatures in the upper 30s
and lower 40s. The primary challenge further out in the extended
will be timing weak short-waves in the prevailing zonal flow
pattern across the conus. In particular, one wave is indicated by
both the ECMWF gem coming into illinois Monday night into
Tuesday... While the GFS shows no such feature. Given such poor
consistency agreement among the models, forecast confidence remains
poor for early next week. At this point, will include just a low
chance pop for rain snow Monday night into Tuesday... But this may
be removed once timing trends become better established.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 507 pm cst Tue dec 18 2018
vfr conditions will prevail through the forecast period, with a
general increase of clouds at or above 15,000 feet. Southeast
winds this evening will become more southerly on Wednesday, with
some afternoon gusts approaching 20 knots at times.

Ilx watches warnings advisories

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.
