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 1131 PM CST Sat Jan 16 2021
SYNOPSIS. Issued at 251 PM CST Sat Jan 16 2021
Light snow will spread across central Illinois tonight and continue into Sunday, as a storm system tracks southeast across the region. Amounts of an inch or two are likely.
UPDATE. Issued at 905 PM CST Sat Jan 16 2021
Upper level shortwave approaching west central IL will continue to produce increasing coverage and rate of snow overnight as it moves into central IL. Initially, some reports of freezing drizzle are noted in west central IL due to shallow cloud depth but this should increasingly switch to all snow overnight as deeper lift associated with the shortwave develops. Overall, updates this evening are minimal, with afternoon forecast package in good shape overall.
SHORT TERM. (This evening through Sunday) ISSUED AT 251 PM CST Sat Jan 16 2021
Earlier round of snow exited the forecast area by midday, with just some patches of drizzle or light snow lingering over the eastern CWA. Robust shortwave was currently located in eastern South Dakota and will close off an upper low over central Illinois Sunday morning. While precipitation remains spotty this evening, an increase in snow is expected in the 9-midnight time frame west of the Illinois River, spreading southeast after midnight. 18Z HRRR suggests the snow could be cutting off as early as midday Sunday, though will go with a more slower diminishing through early afternoon as the associated surface boundary exits eastern Illinois. Accumulations not expected to be overly generous, but an inch to 2 inches appears reasonable over most of central Illinois, with up to an inch south of I-70. Main impacts on travel would likely be in the overnight and morning hours, as temperatures creep up to the freezing mark in the afternoon.
LONG TERM. (Sunday night through Saturday) ISSUED AT 251 PM CST Sat Jan 16 2021
Lingering light snow near the Indiana border is expected to move out early Sunday evening, with mainly dry conditions following into Monday. Another shortwave is expected to drop southeast across the Dakotas Monday afternoon, before tracking across the Great Lakes region. Central Illinois will be caught up in the converging area of the northern and southern jet streams. The main synoptic models all squeeze out some QPF in a band across the mid-Mississippi Valley, though the European model is more focused south of I-70. Will add some chance PoP's for light snow Monday night across mainly the middle third of the forecast area, though soundings show it may end as a bit of freezing drizzle as ice crystals aloft are lost.
With a large upper low cutting off southwest of California early this week, the upper pattern over us won't be conducive to any significant changes until the low weakens and ejects northeast around Thursday. Both the GFS and European model keep much of its remnants to our south, though some precipitation may spread northeast Wednesday night as a weaker wave precedes it.
AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1131 PM CST Sat Jan 16 2021
MVFR cigs are in place across most of the central IL terminals, expected to decrease slowly into IFR along the I-74 terminals overnight. Meanwhile, increasing coverage and rates of snowfall should continue as another disturbance moves into the area. This snow should bring general IFR to MVFR vsbys, as well as an end to patchy freezing drizzle. Potential LIFR cigs/vsbys possible in heavier snow showers. Light snow should begin to taper off from west to east from 21Z- 03Z. Winds W 7-12 kts through the 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.
