Area Forecast Discussion National Weather Service Lincoln IL 625 AM CDT Fri Apr 3 2020
SYNOPSIS. Issued at 231 AM CDT Fri Apr 3 2020
A few light rain showers will be possible today, mainly for areas west of Interstate 55. A much better chance for showers advancing across central Illinois will come tonight into Saturday. Dry weather should return for Sunday. Besides a brief cool down on Saturday, temperatures should remain above normal.
SHORT TERM. (Today and tonight) ISSUED AT 231 AM CDT Fri Apr 3 2020
A retrograding upper level low on the East Coast of the U.S. will cause the approaching cold front to make only very slow progress toward Illinois over the next 24 hours. The front is in western Iowa as of 2 am CDT, and will finally reach our western counties early this evening. The front will depart into Indiana Saturday morning. The slow progress of the front will limit low level convergence along the front. Expansive cloud cover ahead of the front will limit instability ahead of the front, which should keep chances of thunderstorms on the low side. Have not included any mention of storms for today into this evening.
A band of likely/categorical PoPs is in the forecast to push across our forecast area, but QPF looks to remain on the light side, with upwards of a quarter inch from today and tonight.
LONG TERM. (Saturday through Thursday) ISSUED AT 231 AM CDT Fri Apr 3 2020
Saturday will see morning rains ongoing in the morning, as the cold front finally advances out of Illinois. Clouds will likely hold tough behind the front, as colder air filters into the area. That will make Saturday the coolest day of the next week.
High pressure and rising heights on Sunday will help scour out some clouds and bring a warming trend to Illinois. The area will see an extended period of upper level ridging, but a slight shift to the east early next week will establish SW flow aloft. That will provide an opportunity for periodic shortwaves to trigger scattered rain showers from Monday through Tuesday night. Some thunderstorms will possible with that system, due to better MLCAPE instability. No severe weather is anticipated however.
Tuesday is shaping up to the our warmest day of the next week, with highs climbing into the low to mid 70s in most areas, and our southeast counties coming close to 80 degrees. That warmup will be in response to 850 mb temps climbing into the 13C-15C range. A cold frontal passage Tuesday night will bring an end to the rain chances and the warming trend. However, Wednesday is still shaping up to the quite mild, with highs in the upper 60s to around 70. The cooler air will finally filter into central Illinois on Thursday, as highs drop about 10 degrees into the upper 50s to low 60s.
AVIATION. (For the 12Z TAFS through 12Z Saturday morning) Issued at 625 AM CDT Fri Apr 3 2020
Main forecast issues will be in the period after 00Z. As a cold front approaches from the west, ceilings will steadily lower, especially this afternoon. MVFR conditions likely to move in early this evening at KPIA/KSPI, but they may take until closer to 06Z to reach as far as KCMI. The front itself should be near KBMI/KDEC by 06Z, and ceilings are likely to dip below 1,000 feet as showers pick up in intensity. IFR conditions should prevail the remainder of the forecast 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.
