Area Forecast Discussion...Updated Aviation National Weather Service Lincoln IL 541 AM CST Sat Dec 9 2023

(Today through Sunday)
Issued at 328 AM CST Sat Dec 9 2023

08z/2am surface analysis shows a cold front along the Illinois River...with a couple bands of showers and isolated thunderstorms well ahead of it. The showers will continue tracking NE across the area and should be primarily northeast of a Macomb to Springfield line by daybreak. The front will push into Indiana by around midday, bringing an end to precip across the majority of the area.
The exception will be the far SE KILX CWA around Robinson and Lawrenceville where a few showers will linger into the afternoon as a weak wave tracks northeastward along the departing boundary into the Ohio River Valley. High temperatures will be achieved this morning...ranging from the middle 40s in the Illinois River Valley to the upper 50s near the Indiana border.

Once the front passes, winds will veer to the west and skies will partially clear. Meanwhile further north, the parent upper low evident on latest water vapor imagery over Minnesota will push into the Great Lakes and its associated cloud cover will dip southward into north-central Illinois. The end result will be a cloudy afternoon along/north of a Macomb to Bloomington line. May even see a few flurries/sprinkles across northern Illinois...but these will stay north of the CWA.

After a partly to mostly cloudy night, skies will begin to clear west of the I-55 corridor by Sunday afternoon. Thanks to cloud cover early in the day and brisk NW winds, highs will remain below normal for this time of year in the middle to upper 30s. As high pressure moves overhead and skies clear, excellent radiational cooling will allow lows to dip into the lower 20s Sunday night.


(Monday through Friday)
Issued at 328 AM CST Sat Dec 9 2023

Quiet weather is anticipated through the extended as the polar jet remains well to the north across Canada and a cut-off upper low forms over the Great Basin by Tuesday. This feature will gradually shift eastward later in the week, but any precip associated with it will remain west of central Illinois until next weekend. In the meantime, dry conditions will prevail through the entire period.
After a cold day on Sunday with highs in the 30s, readings will quickly rebound into the 40s by Monday...then will climb well into the 40s and lower 50s by Thursday/Friday as upper heights rise in advance of the slowly approaching low.


(For the 12z TAFs through 12z Sunday Morning)
Issued at 540 AM CST Sat Dec 9 2023

11z/5am obs show a cold front crossing the I-55 corridor. Once the boundary passes, winds veer to W/NW and ceilings improve markedly.
VFR conditions are already noted at KPIA/KSPI and will arrive at KBMI/KDEC by 13z...then further east to KCMI by 14z. Westerly winds at 10-15kt with gusts to around 20kt will prevail for the remainder of the day before gradually veering to NW late tonight.
Low clouds associated with a low passing to the north of central Illinois will settle southward tonight as well, resulting in a return to MVFR ceilings at the I-74 terminals overnight.
