Update
Issued at 807 pm cst Tue nov 13 2018
latest surface map shows high pressure ridge from southwest
wisconsin into texas. Cirrus continues to stream across the
southeast third of the forecast area, which the rap suggests will
continue through midnight before shifting southeast. With the high
becoming centered over the CWA by morning, the clear skies will
allow most areas to dip into the mid teens by morning, though
upper teens are more likely south of i-70.

Little change was needed to the gridded forecasts, aside from
updating the sky trends. The zone forecasts were updated to
correct a formatting error in the afternoon issuance.

Short term (this evening through Wednesday)
issued at 303 pm cst Tue nov 13 2018
mostly clear skies expected through Wednesday as central il sits
roughly in a col region between a deepening upper low moving from
the southern plains into the lower mississippi region and upper
troughing heading out of the great lakes into the north atlantic.

Winds will be light and variable with weak surface pressure
gradients over the area, although a tendency toward a northeast
direction will develop during the day as surface low pressure starts
to lift northward into the tn region. The air mass remains far
colder than normal, and resulting lows should be in the teens
tonight, and mid to upper 30s Wednesday.

Long term (Wednesday night through Tuesday)
issued at 303 pm cst Tue nov 13 2018
the upper low developing in the southern plains today looks to
follow a track just south of the ohio river Thursday, spreading
precipitation into southeast illinois starting Wednesday evening
south of i-70, continuing until Thursday evening east of i-57. A
chance for precipitation looks to spread about as far
northwestward as jacksonville to bloomington during the daytime
Thursday. A fairly persistent band associated with the deformation
zone wrapping around the north of this upper low could result in
heavy accumulations of snowfall, 4-7 inches, near and south of the
i-70 corridor, and a winter storm watch has been issued. Although
a wedge of warm air aloft looks to push northward ahead of the
low, current models keep any above freezing temperatures aloft
east of illinois, therefore precipitation type looks to remain
completely snow until a loss of ice aloft potentially switches
precipitation to a brief period of freezing drizzle Thursday
evening.

Dry zonal flow aloft should keep dry conditions over central il
Friday, then a cold front looks to push southeastward across
central il Saturday, resulting in a chance for light rain and
snow. Ahead of the front southwesterly winds should bring highs up
to the 40s Friday, still below normal, followed by highs dropping
back into the 30s to low 40s for Saturday through Monday.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 1110 pm cst Tue nov 13 2018
vfr conditions expected the next 24 hours across the central
illinois TAF sites. Skies to largely remain clear through early
afternoon, then high clouds will stream northward into the area.

Dry air aloft should keep any snow away until after the current
taf period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
