NWS Lincoln, IL wrote its last area forecast discussion before the first event at Jun 5, 5:05 AM CST, 5 minutes earlier. Its key messages:
Area Forecast Discussion...Updated Aviation National Weather Service Lincoln IL 605 AM CDT Wed Jun 5 2024 .KEY MESSAGES... - A cold front is passing through central Illinois this morning, bringing showers and thunderstorms ahead of it. The front should exit to the east of Illinois around early afternoon. - A mainly dry pattern sets up starting this afternoon. A small (10- 20% chance) opportunity for rain arrives this weekend as some MCS type systems pass to our south. - High temperatures stay in the mid to upper 70s through next Wednesday, before warming back up into the 80s for late next week. && .DISCUSSION... Issued at 244 AM CDT Wed Jun 5 2024 As the cold front approaches from the west this morning, some showers and thunderstorms push across central Illinois just ahead of it. Severe threats appear to be low with these storms. These storms will be scattered in a semi-line formation. As it works eastward, locally heavy rainfall is possible. The activity should be out of the area by 18/19z this early afternoon (based on the 06z HRRR), exiting to the east into Indiana. There is secondary weak cold front that will pass through overnight, which could cause some showers to pop up in our far northern counties of the CWA. However, confidence is low so only have 15-20% POPs in the forecast for late this evening through tonight. Once these fronts pass, a surface ridging pattern sets up to our southwest and a upper trough sets up to our northwest, trapping us in the middle. This will allow a mostly dry period for the extended forecast. The next tiny chance for rain comes Saturday and Sunday as MCS activity transverses to our south. There is a 10-20% chance that the systems move just north enough to affect our southern portion of the CWA. As we move closer we can get a better idea of the exact location of these southern MCS systems and if they will directly affect us here in central and southeastern Illinois. Daytime temperatures following this cold front will hang around the mid to upper 70s through next Wednesday. Then it will warm back up into the 80s starting Wednesday afternoon. CPC shows below normal temperatures for the 6-10 day period and near normal to above for the 8-14 day period. Copple && .AVIATION... (For the 12z TAFs through 12z Thursday Morning) Issued at 605 AM CDT Wed Jun 5 2024 A cold front will sweep across the central IL terminals through the morning, producing scattered TSRA for the I-72 corridor southward through 14Z, as well as a band of MVFR cigs. This region of MVFR cigs will last a few hours, then clear out as VFR conditions return for the remainder of the forecast period. Winds SW around 10 kts before the front arrives, followed by NW winds 10-15 kts with gusts around 20 kts after 16Z-20Z. Winds diminishing after 03Z. 37 && .ILX WATCHES/WARNINGS/ADVISORIES... None. &&

An EF-1 tornado touched down about 3.5 miles south of East Lynn along E 3800 North Road, where it completely destroyed seven grain bins and tossed the debris for about a half mile to the east-northeast. A couple power poles were snapped at that location as well. The tornado moved to the east-northeast as it damaged trees, home siding, and the roof of an outbuilding along N 770 East Road. The tornado then progressed in a more northerly direction as it damaged some trees at a residence about a half mile to the north, before dissipating in the field to the northeast after being on the ground for a total of two minutes.
