Area Forecast Discussion National Weather Service Lincoln IL 1140 PM CDT Wed Jun 15 2022 .SYNOPSIS... Issued at 330 PM CDT Wed Jun 15 2022 A cold front moving into the area tonight will bring chances for showers and thunderstorms, and push the hottest air toward southern Illinois for Thursday. Some of the thunderstorms could be severe from Springfield to Champaign northwestward. Areas from Jacksonville to Lawrenceville southward will become very hot again on Thursday, but areas to the north should see less humid conditions Thursday and into the weekend. && .UPDATE... Issued at 900 PM CDT Wed Jun 15 2022 Storms are struggling along the slowly moving front to our west, but what is there is slowly moving into west central IL. Storms are also weakening so some concern that they may dissipate before getting into the CWA. To account for this, have made some adjustments to the pops/wx grids for the rest of the night. Still thinking some storms will get into the area later, so have at least kept some chance pops going with a slight increase to higher pops when the precip arrives at northern sites. Remainder of the forecast looks fine. Update will be coming out shortly. && .SHORT TERM...(This evening through Thursday) ISSUED AT 330 PM CDT Wed Jun 15 2022 A cold front will push southeastward into central IL this evening trailing a shortwave moving into the upper Midwest. MLCAPE values up to 3000 J/kg will precede this front as it approaches the area, along with deep layer shear values 30-40 kts indicating potential for severe thunderstorms, although timing looks to be past peak diurnal heating by the time storms arrive in Galesburg around 8 pm. Instability will slowly diminish overnight with fairly weak lift as the front continues to push southeastward, likely into the I-55 neighborhood around midnight. More uncertainty in coverage develops past midnight as some models eliminate all thunderstorm activity by sunrise. Expect some relief from the heat behind the front, with lows sinking close to 70 degrees and dewpoints dropping into the 60s. The front looks to stall out somewhere between I-70 and I-72 for Thursday, and this will spell one more day of hot weather south of the front. Highs are forecast in the upper 90s south of I-70, trending down to lower 90s north of I-72 for Thursday. Dewpoints in the 70s should linger from Jacksonville to Lawrenceville southward, pushing afternoon heat index values back to the 100 to 105 neighborhood in that area again Thursday afternoon. Have extended the excessive heat warning through Thursday afternoon in Effingham to Lawrenceville area, and issued a heat advisory for a row or two of counties to the north. .LONG TERM...(Thursday night through Wednesday) ISSUED AT 330 PM CDT Wed Jun 15 2022 With the cold front stalled out over southern portions of the forecast area, frontogenesis along that zone or to the north should produce lift triggering additional thunderstorms Thursday evening into Thursday night. CAMs are becoming a little more coherent with developing thunderstorm complexes over that region, rapidly progressing south or southeastward toward the higher instability air. SPC has outlined a Slight Risk for severe thunderstorms containing a main threat of damaging winds, due to large instability and moderate deep layer shear. Once Thursday night's convection moves off to the south, cooler and drier air should surge southward, with highs trending down to the 80s to around 90 for Friday through the weekend along with dry conditions returning. A large scale ridge will build back into the area early next week, resulting in a return of high heat and humidity. Highs should surge well into the 90s with heat index exceeding 100 if not approaching 110. && .AVIATION...(For the 06Z TAFS through 06Z Thursday night) Issued at 1140 PM CDT Wed Jun 15 2022 VFR conditions will prevail at all sites. Does not look like thunderstorms will affect any of the sites, so it has been pulled at all sites. AC around 10k-12kft will affect the sites overnight, but during the morning hours, this will dissipate or push off to the east as the front sags south of the sites. Then just cirrus during the day and clear tomorrow evening. Winds will be southwest to westerly through the period, with speeds of 15kts or less. && .CLIMATE... Issued at 745 PM CDT Tue Jun 14 2022 Latest 6-10 and 8-14 day outlooks from the Climate Prediction Center show high probabilities for above normal temperatures next week. CIPS analogs highlighting >80% probabilities in the day 9-11 period for Wednesday-Friday of next week, with CPC showing a moderate risk of excessive heat during that period. Between this week's heat and next week, we will need to keep an eye on potential for flash drought development. Experimental NIDIS flash drought tool has begun to highlight areas along the I-70 corridor for this potential, though more of east central Illinois is in the drier stages at this point and is also susceptible. In terms of the current heat, a few record highs are still in jeopardy for Wednesday: City Peoria...... 98 in 1894 Springfield. 100 in 1987 Lincoln..... 102 in 1987 Champaign... 97 in 1987 Normal...... 99 in 1894 Decatur..... 100 in 1987 Galesburg... 93 in 1994 Danville.... 98 in 1913 Effingham... 101 in 1902 Paris....... 97 in 1925 Olney....... 101 in 1952 Jacksonville 99 in 1987 Tuscola..... 98 in 1987 Charleston.. 97 in 1913 Record warm low temperatures: City Tue/Jun 14 Wed/Jun 15 Peoria...... 77 in 1981 75 in 1886 Springfield. 76 in 1994 75 in 2016 Lincoln..... 73 in 1981 76 in 1991 && .ILX WATCHES/WARNINGS/ADVISORIES...
