What 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 May 22, 12:11 PM CDT, 1 hour 57 minutes earlier.
Area forecast discussion, May 22, 12:11 PM CDT, 1 hour 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1211 PM CDT SUN MAY 22 2011 .DISCUSSION... ISSUED 1023 AM CDT SUN MAY 22 2011 PRIMARY FORECAST CONCERN IS WITH SEVERE WEATHER POTENTIAL. MOST RECENT SPC OUTLOOK HAS THE NORTHWEST 2/3 OF THE CWA AS PART OF A MODERATE RISK OF SEVERE WEATHER. LARGE AREA OF CLEAR SKIES HAS BEEN OVER MUCH OF THE CWA THIS MORNING...EXCEPT FOR SOME SCATTERED SHOWERS/THUNDERSTORMS NEAR I-70 NORTHEAST TO NEAR DANVILLE. NORTHWEST HALF OF THE CWA STILL RATHER CAPPED PER LATEST LAPS ANALYSIS...BUT CAP SHOULD ERODE QUICKLY THROUGH EARLY AFTERNOON. MODIFYING THE 12Z ILX SOUNDING FOR AFTERNOON CONDITIONS YIELDS CAPE VALUES OVER 3000 J/KG AND NO CAP BY 21Z. ANALYSIS OF SRH...LAPSE RATES...VGP...AND BRN SHEAR FROM THE LATEST NAM MODEL IS SUPPORTIVE OF SUPERCELL DEVELOPMENT ALONG EITHER SIDE OF THE MISSISSIPPI RIVER BY LATE AFTERNOON. MAIN QUESTION IS WITH TIMING OF DEVELOPMENT. LATEST NAM MODEL SUGGESTS THE STORMS WOULD BE AS FAR EAST AS I-55 BY MID AFTERNOON...WITH THE HRRR...RUC AND 4KM ARW/NMM MODELS KEEPING THINGS WEST OF GALESBURG AND RUSHVILLE UNTIL LATE AFTERNOON. NO OBVIOUS FORCING MECHANISM AS FAR EAST AS I-55 AT THAT TIME...SO WILL LEAN MORE TOWARD THE TIMING ON THE OTHER MODELS FOR NOW. ZONE/GRID UPDATE EARLIER WAS PRIMARILY DONE TO REFLECT THE SHOWER TRENDS IN EAST CENTRAL ILLINOIS...AS WELL AS UPDATE WEATHER GRIDS TO MENTION SEVERE THREAT. TEMPERATURES AND WINDS STILL LOOK GOOD. GEELHART && .AVIATION... ISSUED 1211 PM CDT SUN MAY 22 2011 LITTLE CHANGE MADE TO PREVIOUS TAF SET. MAIN CONCERN REMAINS WITH THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON AND EVENING. INDIVIDUAL STORMS INITIALLY WILL BE CAPABLE OF PRODUCING WINDS OVER 50 KNOTS AS WELL AS HAIL...THEN WILL TRANSITION MORE INTO A SOLID LINE AS THE STORMS PUSH FURTHER EAST ACROSS THE TAF SITES. MOST LIKELY TIME FRAME FOR THE WORST OF THE STORMS APPEARS TO BE AS EARLY AS 23-24Z AROUND KPIA/KSPI...RANGING TO AROUND 02-03Z AROUND KDEC/KCMI. ONCE THE LINE PASSES...VFR CONDITIONS TO PREVAIL. INCREASING PRESSURE GRADIENT LATE IN THE PERIOD SHOUD ALLOW GUSTS TO REACH 20-25 KNOTS AGAIN BY LATE MONDAY MORNING. GEELHART && .PREV DISCUSSION... ISSUED 330 AM CDT SUN MAY 22 2011 UNSETTLED WEATHER PATTERN EXPECTED THROUGH MID WEEK ACROSS CENTRAL IL. SPC CONTINUES SLIGHT RISK OF SEVERE STORMS TODAY AND SHIFTS SLIGHT RISK SOUTH OF I-70 MON AND TUE. 00Z MODELS ARE IN DECENT AGREEMENT NEXT FEW DAYS AND EVEN 00Z GFS AND ECMWF IN FAIR AGREEMENT WITH HANDLING UPPER LEVEL LOW MOVING INTO IL DURING MID WEEK. BUT QPF FIELDS WITH MCS/S CONTINUE TO VARY BETWEEN MODELS AND FROM ONE MODEL RUN TO THE NEXT...SO CONFIDENCE IN RAINFALL AMOUNTS EACH PERIOD IS LOW. HPC PAINTS HEAVY QPF OVER CENTRAL AND SW IL INTO MO NEXT 5 DAYS SO FLOOD POTENTIAL WILL LIKELY INCREASE THROUGH MID WEEK. SHORT TERM...TODAY THROUGH TUESDAY NIGHT. WEAKENING MCS WITH ASSOCIATED SCATTERED THUNDERSTORMS MOVING EAST ACROSS EASTERN IA...NE MO INTO NW IL TOWARD THE IL RIVER WITH A THUNDERSTORM NORTH OF PEORIA AND FROM QUINCY WEST. RADAR MOSAIC SHOWS OUTFLOW BOUNDARY JUST EAST OF THE IL RIVER AND SHOWED THE WARM FRONT LIFTING NE OF DANVILLE AROUND 1 AM WHEN SE WINDS SHIFTED SOUTH. STRONG 995 MB LOW PRESSURE WAS OVER CENTRAL SD WITH ITS WARM FRONT OVER FAR NE IL NEAR CHICAGO. FAIRLY MOIST DEWPOINTS OVER CENTRAL/SE IL FROM 60-65F WITH SOUTH WINDS 5 TO 15 MPH. ALOFT UPPER LEVEL RIDGE THAT WAS OVER IL 24 HOURS AGO HAD SHIFTED EAST INTO THE APPALACHIANS WHILE STRONG 553 DM 500 MB LOW WAS ALONG THE SD/NE BORDER PUTTING IL IN A SW UPPER LEVEL FLOW. MODELS CONTINUE TO BRING STRONG SURFACE AND UPPER LEVEL LOW INTO NORTHERN WI BY DAWN MONDAY. AIR MASS IN WARM SECTOR OVER CENTRAL IL GETS QUITE UNSTABLE BY AFTERNOON WITH CAPES ELEVATING BETWEEN 2000 AND 3500 J/KG AND HIGHEST SE OF THE IL RIVER. ISOLATED TO SCATTERED CONVECTION TO OCCUR THIS MORNING OVER CENTRAL IL AND EXPECT MORE WIDESPREAD CONVECTION TO DEVELOP DURING MID/LATE AFTERNOON ESPECIALLY OVER THE IL RIVER VALLEY. SPC HAS ALL OF AREA IN A SLIGHT RISK THIS AFTERNOON AND EVENING WITH 30% CHANCE OF VERY LARGE HAIL 2 INCH OR LARGE WEST OF I-57...30% OF DAMAGING WIND GUSTS FROM THE IL RIVER SE AND 10% RISK OF STRONG TORNADOES OVER THE IL RIVER VALLEY. HIGHS IN THE MID TO UPPER 80S WITH MUGGY DEWPOINTS IN THE MID TO UPPER 60S BY AFTERNOON. BREEZY S/SW WINDS 15 TO 25 MPH AND GUSTS TO 30 MPH BY AFTERNOON. CONVECTION CHANCES TO DIMINISH OVERNIGHT BUT EXPECT MORE TO DEVELOP BY MON AFTERNOON WITH ANOTHER WARM AND HUMID DAY WITH HIGHS IN THE LOW TO MID 80S EXPECTED WITH COLD FRONT SETTLING SOUTHWARD INTO NORTHERN IL. SPC SHIFTED SLIGHT RISK OF SEVERE STORMS SOUTH OF I-70 WHERE AIR MASS MORE UNSTABLE. FRONTAL BOUNDARY APPEARS TO PRESS INTO SOUTHERN IL BY TUE AND THEN BECOME MORE ACTIVE WITH SHORT WAVES AND LOW PRESSURE MOVING ALONG IT. SO LIKELY CHANCES OF SHOWERS AND THUNDERSTORMS SHIFT NORTHWARD FROM SOUTHERN IL INTO CENTRAL IL BY TUE. SPC CONTINUES SLIGHT RISK OF SEVERE STORMS SOUTH OF I-70 TUE. NOT AS WARM OVER CENTRAL IL TUE WITH HIGHS RANGING FROM LOWER 70S FROM I-74 NORTH TO THE UPPER 70S AND LOWER 80S IN SE IL. LONG TERM...WEDNESDAY THROUGH SATURDAY. ANOTHER STRONG CUTOFF UPPER LEVEL LOW AND ASSOCIATED SURFACE LOW TO EMERGE OVER THE CENTRAL PLAINS BY WED AND MOVE INTO IL THU. THIS TO LIKELY BRING MORE SHOWERS AND THUNDERSTORMS TO CENTRAL AND SE IL WITH HEAVY RAINS ALSO A THREAT. WILL CONTINUE A TEMP GRADIENT FROM COOLER READINGS NORTH TO WARMER READINGS SOUTH DURING MID WEEK. UPPER LEVEL LOW WEAKENS AS IT SHIFTS EAST OF IL FRI BUT ANOTHER UPPER LEVEL LOW/TROF TO SETTLE INTO THE MIDWEST NEXT WEEKEND KEEPING A CHANCE OF SHOWERS AROUND ALONG WITH BELOW NORMAL TEMPS.
