Area Forecast Discussion...Updated Aviation National Weather Service Lincoln IL 503 PM CST Tue Jan 14 2025
KEY MESSAGES
- Temperatures will drop rapidly tonight, especially where snow cover exists. Temperatures are expected to drop below zero for most areas southeast of the Illinois River, as low as minus 10 in a few spots.
- Temperatures will become considerably milder for a few days Thursday into Friday night, peaking with highs near 40 Friday.
- Light rain will develop Friday night, especially east of the Illinois River, perhaps mixing with snow by Saturday morning.
Accumulating snow is not anticipated at this time.
DISCUSSION
Issued at 253 PM CST Tue Jan 14 2025
A few snow flurries will taper off this afternoon, with high pressure currently centered near western IA set to drift across central IL overnight. With at least light snow cover over most of the area, temperatures should plummet. Clear skies will promote good radiational cooling and enhanced decoupling of winds for generally calm winds, while a cold air mass characterized by a -10 to -12 C 925 mb temperature combines with the calm winds. The result should be generally 0 to -10 degree temperatures across the area, with guidance pointing toward the lowest potential generally south of I- 70 where the high should be situated at sunrise and some of the deepest snowpack exists.
As the high shifts to the east the next few days, southwesterly flow will develop, bringing a warming trend that should result in temperatures rising up to the 30s Thursday, and around 40 Friday, after highs Wednesday still struggle to warm above 20. Additional snow is unlikely, but a shortwave passing just north of the area Wednesday night will bring a slight chance to portions of east central IL. The next system Friday night looks to bring strong enough warm advection to promote nearly all rain until the cold front arrives late Friday night into Saturday morning to potentially change precipitation type back to snow for a brief time.
Following Saturday morning's cold front, much colder air will return again, bringing highs back to the teens and potentially single digits Sunday into early next week, as well as single digits to below zero lows, and wind chills well below zero at times.

VFR conditions will prevail the next 24 hours, with just a few clouds around 7,000 feet moving in from the west in the afternoon.
Winds will be light and variable tonight as high pressure drifts overhead, then become southwest by late morning after its departure.
