MillerWhat forecasters said that day
The local office's own words before this areal flood 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 areal flood warning went out at Jun 26, 12:33 AM CDT, 2 hours 1 minute earlier.
Area forecast discussion, Jun 26, 12:33 AM CDT, 2 hours 1 minute before
Area Forecast Discussion National Weather Service Lincoln IL 1233 AM CDT Sat Jun 26 2021 .SYNOPSIS... Issued at 646 PM CDT Fri Jun 25 2021 Thunderstorms will develop across central Illinois this evening...particularly along and north of a Shelbyville to Paris line where some of the storms could potentially produce damaging wind gusts and heavy rainfall. The storms will gradually diminish toward dawn Saturday. && .UPDATE... Issued at 857 PM CDT Fri Jun 25 2021 Thunderstorms continue to develop along an outflow boundary from central Missouri E/NE into central Illinois this evening. The storms are being aided by a 30-40kt 850mb jet oriented from the Ozarks northward into Illinois. 0150z/850pm radar imagery shows the strongest cells along a Jacksonville...to Lincoln...to Bloomington line. Based on radar trends and latest HRRR forecast, think the line will gradually shift southward and will focus along the I-72 corridor for the next few hours. While overall severe threat will decrease as daytime instability wanes, attention will turn to potential flash flooding as training echoes drop locally heavy rainfall across that area. Most model guidance suggests the rainfall will slowly decrease in intensity after midnight as the precip becomes more scattered in nature toward dawn Saturday. Updated the forecast to better reflect PoP trends for the remainder of the night. && .SHORT TERM...(This evening through Saturday) ISSUED AT 343 PM CDT Fri Jun 25 2021 Surface analysis this afternoon depicts a stationary front stretched from northern IL into IA well north of the area. An outflow boundary is positioned across southeast IL into central MO with convection ongoing in our far southeast IL counties as well as new activity firing over central MO as of 3 PM. Elsewhere, a break from the precipitation is occurring with some breaks in the clouds noted across west-central portions of the state. SPC mesoanalysis depicts MLCAPE starting to build northward with clearing, though we remain capped (50-150 J/kg) from about I-70 northward from earlier convection. This will prevent anything from developing in these areas for the next few hours. Confidence in the evolution of activity going into tonight remains low. Once the CAP erodes, scattered storms should develop across west-central IL along the ouflow boundary sometime later this afternoon or early evening, which the 25.18Z HRRR picks up on. However, CAMs have not been performing well. The idea is that coverage will increase by tonight as a few mid-level waves ripple through the southwest flow aloft and the LLJ kicks in. Strong to severe storms remain possible across locations south of I-74 with damaging winds and large hail being the main threats. However, decent low- level shear with a boundary in the area could support a brief tornado or two. Additional rainfall amounts through Saturday morning look to range from 1-2" north of I-70, with higher amounts possible where storms train. With 1 to 3 hr flash flood guidance ranging from 1.5 to 2.5" due to recent soaking rains. Because of this, a Flash Flood Watch remains in effect for counties north of I-70 through Saturday morning. .LONG TERM...(Saturday night through Friday) ISSUED AT 343 PM CDT Fri Jun 25 2021 The upper-level pattern remains in a blocking regime this weekend and even into the new week, keeping periods of showers and storms possible. Shower and storm chances look to taper off Saturday morning as the LLJ recedes. Additional thunderstorm development looks likely along any remnant boundaries by the afternoon into evening hours of Saturday, pending how quickly the atmosphere destabilizes after overnight convection. A similar story going into Sunday with the same set up. All in all, additional rainfall amounts Saturday through Monday morning look to range from 1-3" north of I- 70. Shower and storm chances remain possible through a good portion of the week with the blocking pattern keeping southwest flow positioned over the local area. Let the NBM handle PoPs through the week for the time being. The pattern finally begins to change by the end of the week into next weekend as the ridging over the eastern CONUS/Atlantic breaks down. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1229 AM CDT Sat Jun 26 2021 A line of thunderstorms continues from roughly CMI through DEC and through TAZ this hour and will very slowly shift east and weaken with time. Further west, precip is more stratiform with embedded thunder. Anticipate precip coverage to diminish overnight, but spotty showers and storms will be possible through the period. Thunderstorms will redevelop Saturday afternoon and evening, somewhere near the I-55 corridor though have low confidence in specifics. Wherever these storms develop, storms will move NE but the line will very slowly progress eastward. S/SW winds will prevail through the period outside the influence of storms. && .ILX WATCHES/WARNINGS/ADVISORIES...
