8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.

Area Forecast Discussion National Weather Service Lincoln IL 733 PM CST Sat Nov 28 2020
SYNOPSIS. Issued at 253 PM CST Sat Nov 28 2020
Dry and seasonable weather will continue through tomorrow. However, a weather system will move northeast across the southern Mississippi valley and spread precipitation across parts of the eastern half of Illinois Sunday night through Monday. Gusty northwest winds are expected behind this system as much colder air moves into the region for next week.
UPDATE. Issued at 733 PM CST Sat Nov 28 2020
Just a few high clouds moving across the state so far this evening, but a larger cirrus shield is advancing northeast through Missouri. Main arrival of these clouds into central Illinois will be after midnight. Southwest winds expected to persist through the night, keeping temperatures milder than last night, but lows at or just below freezing are still likely. Some minor updates have been made to the gridded forecasts to account for latest trends, but the overall forecast is on track.
SHORT TERM. (This evening through Sunday) ISSUED AT 253 PM CST Sat Nov 28 2020
High pressure located southeast of the CWA will continue to bring unseasonably warm and dry weather to the area through Sunday. Another warm day is expected tomorrow with plenty of sunshine and breezy southwest winds. High are expected to reach to around 50 by afternoon.
LONG TERM. (Sunday night through Saturday) ISSUED AT 253 PM CST Sat Nov 28 2020
In the southern stream, a weather system will move northeast from the southern Mississippi valley toward the Carolinas. In the northern stream, a cold front will push into the area. These two systems will phase into one, but not until Monday night over the eastern US. As these two systems phase, clouds and precip will spread across the eastern half of the CWA for Sunday night through Monday. The precip should begin as rain but then quickly become mixed with snow, and then later changing to all snow late Sunday night, as colder air advects into the area behind the cold front. The greatest chance of precip will remain east of I-57, but some of it could extend as far back as I-55, though any amounts of precip will be very small west of I-57. At this point, any snowfall amounts looks to be less than an inch and confined to areas east of I-57. Gusty northwest winds will accompany the colder air quickly moving into the area Sun night and Monday. Gusts to around 35 mph should be common across the area through the Sun night through Monday period.
Once the effects of this system move east of the CWA, dry and colder weather is expected for most of the coming week. The coldest night looks to be Mon night when overnight lows will range from 17 in the northwest to the mid 20s in the southeast. Temps will moderate a little through the week, but below normal temps are expected.
There is a chance of another weather system effecting the CWA late in the week, but the models can not agree on timing or placement right now. So, a blended ensemble forecast looks fine for Thur night through Sat, which only produced some slight chances over the CWA.
AVIATION. (For the 00Z TAFS through 00Z Sunday evening) Issued at 510 PM CST Sat Nov 28 2020
VFR conditions expected the next 24 hours, with a gradual increase in cloud cover overnight into Sunday. Heights generally expected to be above 10,000 feet, though a late afternoon steady decrease is expected along a cold front. This front will cross the central Illinois TAF sites between 19-24Z, latest at KCMI, with winds turning northwest and increasing to around 10 knots.

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.
