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 Aug 18, 3:06 PM CDT, 2 hours 13 minutes earlier.
Area forecast discussion, Aug 18, 3:06 PM CDT, 2 hours 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 306 PM CDT TUE AUG 18 2015 .SHORT TERM...(TONIGHT) ISSUED AT 306 PM CDT TUE AUG 18 2015 CENTRAL ILLINOIS IN THE MIDST OF A PROGRESSING SEVERE WEATHER EVENT THIS AFTERNOON AS A COLD FRONT APPROACHES THE AREA. SCATTERED SHOWERS AND THUNDERSTORMS GETTING A LOT OF ASSIST FROM DIURNAL HEAT OF DAY IN HUMID AIRMASS. WEAK OUTFLOW BOUNDARY FROM STORMS THIS MORNING TO THE NORTHEAST HAS BEGUN TO PUSH BACK TO THE NE AS A DEVELOPING WARM FRONT. HOT AND HUMID WITH MORE SOUTHERLY FLOW TO THE SOUTH, AND METARS TO THE NE MORE SOUTHEASTERLY AND SLIGHTLY COOLER. WEAK LAPSE RATES WOULD LEND TO MORE OF A DAMAGING WIND THREAT, BUT TO THE NORTHWEST AND NORTH CENTRAL PORTIONS OF THE STATE HAVE JUST ENOUGH BACKING IN THE LOW LEVEL WINDS TO PROMPT A THREAT FOR ROTATING STORMS/ISOLATED TORNADO THREAT. CHANCES FOR WIDESPREAD SEVERE WEATHER THREAT SHOULD DIMINISH SOMEWHAT AFTER SUNSET, ALTHOUGH THE THUNDERSTORM RISK WILL REMAIN IN PLACE AHEAD OF THE COLD FRONT ALL NIGHT. CLOUDY SKIES AND LOW TEMPERATURES DROPPING TO THE LOWER 60S NW OF THE ILLINOIS RIVER VALLEY AND STILL IN THE LOWER 70S SOUTHEAST OF I-70. && .LONG TERM...(WEDNESDAY THROUGH TUESDAY) ISSUED AT 306 PM CDT TUE AUG 18 2015 COLD FRONT TO THE NORTHWEST EXPECTED TO SLOW AS IT ENTERS CENTRAL ILLINOIS AND PROVIDE A FOCUS FOR PRECIP CHANCES THROUGH TOMORROW NIGHT. SOME MAJOR DISCREPANCIES IN A FEW THINGS FOR THE MODELS WITH THIS RUN. THE FIRST ONE IS CONCERNING THE CLEARING OF THE COLD FRONT CURRENTLY TO THE NW. MODELS HAVE HELD OFF IN CLEARING THE PRECIP OUT OF THE FA BY 06Z THURSDAY MORNING THIS RUN. AFTER THE COLD FRONT PASSES THROUGH THE FA, AND THE SFC LOW CENTER PULLS OFF TO THE NE THROUGH THE GREAT LAKES...HIGH PRESSURE BUILDS BACK IN AND KEEPS THE FORECAST RELATIVELY DRY THROUGH THE END OF THE WEEK. THE NEXT SYSTEM IS ON TRACK FOR THE FIRST PART OF THE WEEKEND. STILL SOME MAJOR ISSUES WITH THE ONSET OF THE PRECIP DIFFERING BY 6 TO 12 HOURS IN THE WESTERN PORTIONS OF THE STATE SAT NIGHT/SUN MORNING. THIS SAME TIME DIFFERENCE ALSO REMAINS IN THE EXIT OF THE SYSTEM FOR SUN AFTERNOON/SUN OVERNIGHT INTO MON. AS A RESULT THE LONG RANGE OF THE FORECAST HAS A FEW PDS WITH CHANCE POPS WITH THE SUPERBLEND. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON) ISSUED AT 1241 PM CDT TUE AUG 18 2015 COMPLICATED AVIATION FORECAST FOR ILX TERMINALS. IN GENERAL, TERMINALS ARE CAUGHT BETWEEN THE IMPACTS OF THE ONGOING PRECIP DUE TO A DISTURBANCE OVER CMI...AND AN APPROACHING COLD FRONT OVER A HOT AND HUMID AIRMASS. SOME RESIDUAL RH TRAPPED IN THE BOUNDARY LAYER FED A LOW STRATUS DECK THAT IS SLOW TO RESOLVE IMPACTING BMI, AND CMI TO A LESSER DEGREE. AREAS NOT IMPACTED BY THE STRATUS ARE FILLING IN WITH A DENSE CU FIELD EITHER WAY PUTTING A BKN CIG VERY CLOSE TO BREAK BETWEEN VFR AND MVFR. COLD FRONT TO THE NW IS INCREASING CHANCES FOR TS IN THE OVERNIGHT, BUT NO ONE PD IS BETTER CHANCES THAN OTHERS BEFORE DAWN AND THE MODELS SPEEDING UP THE FRONT LATER TONIGHT AND CLEARING BEFORE 12Z IS SUSPICIOUS. SHORT RANGE/HI RES MODELS CHANGING FROM RUN TO RUN WITH IMPACTS OF PRECIP AS WELL. KEEPING TO TRENDS FOR OVERNIGHT VCTS, SHRA IN HIGHEST CONFIDENCE, MVFR CIGS AT LEAST TO START EARLY MORNING TREND, AND NOT CLEARING AS QUICKLY UNDER WEAK CYCLONIC FLOW. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...HJS LONG TERM...HJS AVIATION...HJS
