ErwinWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 17, 3:16 PM CDT, 2 hours 27 minutes earlier. Its key messages:
- A Tornado Watch is in effect until 10pm CDT for locations along and south of a Macomb to Chenoa line. All severe hazards are possible...with the greatest probability for strong tornadoes focusing south of a Springfield to Paris line.
- Quiet weather will prevail Thursday through Saturday...with the next chance for thunderstorms arriving by Sunday.

Area Forecast Discussion National Weather Service Lincoln IL 316 PM CDT Wed Jun 17 2026 .KEY MESSAGES... - A Tornado Watch is in effect until 10pm CDT for locations along and south of a Macomb to Chenoa line. All severe hazards are possible...with the greatest probability for strong tornadoes focusing south of a Springfield to Paris line. - Quiet weather will prevail Thursday through Saturday...with the next chance for thunderstorms arriving by Sunday. && .DISCUSSION... Issued at 316 PM CDT Wed Jun 17 2026 19z/2pm mesoanalysis shows an outflow boundary left behind by the morning convection along a Quincy...to Litchfield...to Salem line. This is considerably further south than previously thought: therefore the most significant risk for widespread severe weather later this afternoon and evening has shifted south as well. As such, the new Tornado Watch coordinated with SPC does not include the far northern KILX CWA from the Peoria area northward. MLCAPEs are currently under 1000J/kg: however, as the boundary mixes slowly northward this afternoon, the RAP suggests MLCAPEs will increase into the 1500-2000J/kg along/southeast of a Quincy to Champaign line over the next couple of hours. Impressive wind fields aloft are contributing to very strong 0-6km bulk shear of 60-80kt...while 0-1km shear values remain in the 30-40kt range. Given marginal instability and extreme shear, am expecting supercell thunderstorms to rapidly develop along/ahead of a slowly advancing cold front across the Illinois River Valley imminently. All severe hazards will be in play...including damaging wind gusts in excess of 70mph, hail larger than golf balls, and tornadoes. The Significant Tornado Parameter (STP) is currently maximized closer to the outflow boundary from central/northern Missouri across south-central Illinois, but is progged to lift northward later this afternoon/evening. At this time, it appears the highest probability of potentially strong tornadoes will focus along/south of a Springfield to Paris line. Thunderstorms are currently developing in a band from Galesburg/Rushville eastward to Pontiac/Champaign. CAMs have generally sped up the development process, as well as the gradual S/SE movement of the band. As a result, think the primary severe risk will be focused along the I-72 corridor between 4pm and 6pm, then will sink toward I-70 by 7pm to 9pm. The primary line of convection will exit the far SE KILX CWA around midnight: however, a few showers may linger further north throughout the evening into the first part of the overnight. A short-wave trough will bring a period of mid-level cloudiness to central Illinois Thursday morning, with forecast soundings suggesting the potential for a few light rain showers mostly along/south of a Rushville to Robinson line where slight chance PoPs (20%) are warranted. Once this wave departs, a return to cool and mostly dry weather will be on tap for Friday and Saturday. The next significant chance for precipitation will hold off until late Saturday night into Sunday as a stronger short-wave trough traverses the Plains and approaches from the west. Given better deep-layer moisture and strong forcing, think showers and thunderstorms will become widespread. The severe weather risk remains uncertain at this time, with several machine learning algorithms such as Colorado State and NSSL keeping the greatest probabilities further south. A few NCAR members do however suggest 15-30% probs northward into central Illinois, so will need to keep an eye on mesoscale details as the time nears. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1247 PM CDT Wed Jun 17 2026 Convection is ongoing across central Illinois early this afternoon: however, 1740z/1240pm radar imagery shows the back edge of the precip along a KGBG to KSPI line. Based on radar/satellite trends, it appears the terminals will see a couple hour break as the afternoon progresses before a final line of thunderstorms forms from the Iowa/Missouri border eastward into the area after 19z/20z. Following the latest HRRR/RAP solution closely, have highlighted thunder with visbys down to 1 mile at KPIA between 19z and 21z...then further south to the I-72 sites between 22z and 00z. Once the convective line settles further south, scattered showers will remain possible until early evening. After that, am expecting skies to become mostly clear through much of the evening before a layer of mid-level clouds AOA 15,000ft spreads across the area by Thursday morning. Winds are highly variable at the moment due to ongoing storms, but will become southeasterly this afternoon...then westerly this evening as a cold front passes. && .ILX WATCHES/WARNINGS/ADVISORIES... Flood Watch until 10 PM CDT this evening for ILZ027>031- 036>038.
