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 Jun 21, 3:05 PM CDT, 1 hour 50 minutes earlier.

Area forecast discussion, Jun 21, 3:05 PM CDT, 1 hour 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
305 PM CDT FRI JUN 21 2013

.DISCUSSION...
ISSUED 300 PM CDT FRI JUN 21 2013

INITIAL CONCERNS WILL FOCUS ON THE SEVERE POTENTIAL WITH THE LINE
OF STORMS MOVING ACROSS OUR NORTHERN COUNTIES. THEN ATTENTION
TURNS TO THE HEAT AND HUMIDITY WITH PERIODIC STORM CHANCES IN THIS
SUMMER PATTERN. THE EXTENDED FORECAST STILL CALLS FOR OUR NEXT
COLD FRONT TO ARRIVE AROUND THURSDAY.

SHORT TERM...TONIGHT THROUGH MONDAY.

A 30-40 MPH SOUTHWARD MOVING GUST FRONT IS GENERALLY OUTRUNNING
THE LINE OF STORMS BY 5 TO 10 MILES IN MOST AREAS...EXCEPT FOR IN
THE MID-PORTION OF THE LINE FROM DELAVAN TO BLOOMINGTON. STORM
INITIATION REMAINS CLOSER TO THE GUST FRONT IN THAT AREA. THOSE
STORMS ARE THE STRONGEST AT 230 PM...BUT STILL APPEAR TO BE SUB-
SEVERE. HAIL AND WIND REPORTS HAVE BEEN SPARSE, BUT A FEW TREE LIMBS
MAY HAVE BEEN KNOCKED DOWN NEAR DUNLAP AND THE LARGEST HAIL REPORT
WAS DIME SIZED 1N OF MOSSVILLE EARLIER. STORM INTENSITY HAS
GENERALLY WEAKENED SINCE THOSE REPORTS...SO WE CONTINUE TO MONITOR
FOR ANY INTENSIFICATION. SPC MESO-ANALYSIS PAGE SHOWS MORE STABLE
AIR AHEAD OF THE STORMS...WITH WEAKER 0-6KM BULK SHEAR. THERE IS
STILL 1500 J/KG MUCAPE AVAILABLE...SO THE STORMS MAY LINGER AT
LEAST UNTIL THE INDIANA BORDER EARLY THIS EVENING.

INTO EARLY EVENING...A COUPLE 4KM MODELS ARE SHOWING ADDITIONAL
STORM DEVELOPMENT FARTHER WEST IN EASTERN IOWA/NE MO WHERE
INSTABILITY AND SHEAR PARAMS ARE MORE FAVORABLE FOR STORMS.
HOWEVER...THE 18Z HRRR RUN DOES NOT HAVE ANY INDICATION OF THOSE
STORMS. TAKING EVERYTHING INTO CONSIDERATION...WE TRIED TO MAKE
THE POPS/WEATHER GRIDS CONFORM CLOSELY TO THE NEXT 3-5 HOURS OF
CONVECTION...THEN WENT MORE GENERAL BASED ON SATELLITE, RADAR AND
OBSERVATION TRENDS. WE LINGERED SOME HIGHER POPS THROUGH 03Z THIS
EVENING IN THE EAST TO TREND THE CURRENT STORMS EASTWARD...WITH
SLIGHT CHANCE IN OUR WESTERN COUNTIES TO COVER THE NEXT LINE THAT
MAY ARRIVE.

THE REST OF THE NIGHT SHOULD BE MUGGY AND MILD...AS CLOUDS CLEAR
OUT AND LINGERING NORTH WINDS BEHIND THIS LINE OF STORMS RETURNS
TO SOUTHERLY.

SATURDAY WILL BRING ANOTHER ROUND OF AFTERNOON SHOWERS AND STORMS
AS HIGHS CLIMB INTO THE LOWER 90S AND HEAT INDICES REACH AROUND
100. SEVERE CHANCES SHOULD REMAIN LOW IN OUR COUNTIES...WITH THE
SLIGHT RISK FOR DAY 2 NW OF ILLINOIS. THE TRIGGERS FOR STORMS MAY
BE TIED TO THE RESIDUAL OUTFLOW BOUNDARIES FROM TODAY'S
CONVECTION...AND THE PASSAGE OF A WEAK 500 MB SHORTWAVE.
PRECIPITABLE WATER VALUES AROUND 1.75" WILL ALLOW SOME OF THE
STRONGER STORMS TO BE VERY HEAVY RAIN PRODUCERS...WITH RAINFALL
RATES OF 1-2" PER HOUR. LOCALIZED FLASH FLOODING WILL BE
POSSIBLE...DESPITE THE RELATIVELY DRY CONDITIONS OVER THE PAST
COUPLE OF WEEKS IN MOST AREAS. STORMS SHOULD COME TO AN END BY
SATURDAY EVENING...WITH CLEARING SKIES OVERNIGHT.

SUNDAY WILL SEE LESS FAVORABLE INSTABILITY PARAMS...AS MID LEVEL
WARMING PROVIDES A BETTER CAP ON STORM DEVELOPMENT. WE KEPT A DRY
FORECAST FOR SUNDAY...BUT KEPT THE HEAT AND HUMIDITY HIGH. HEAT
INDEX READING SHOULD REMAIN BELOW SATURDAYS READINGS...BUT STILL
IN THE MID TO UPPER 90S.

MONDAY WILL SEE THE RETURN OF STORM CHANCES AS THE NEXT 500MB
SHORTWAVE CREATES SOME FALLING HEIGHTS AND DESTABILIZES THE LOWER
TROPOSPHERE. STORM DEVELOPMENT SHOULD OCCUR IN THE AFTERNOON...AS
SURFACE HEATING HELPS TO ERODE THE CAP. WE WENT WITH CHANCE POPS
IN THE NW HALF OF OUR FORECAST AREA...WITH SLIGHTS DOWN TO I-70.

LONG TERM...TUESDAY THROUGH FRIDAY.

ANOTHER LULL IN THE STORMS IS EXPECTED MONDAY NIGHT THRU TUESDAY
NIGHT...AS THE UPPER TROUGH IN THE N PLAINS BEGINS TO BECOME
PROGRESSIVE. AS THE UPPER TROUGH REACHES THE GREAT LAKES...A
SURFACE COLD FRONT IS FORECAST TO MOVE ACROSS ILLINOIS ON THURSDAY
OR THURSDAY NIGHT. SHOWERS AND STORMS WILL LIKELY DEVELOP ALONG
THAT FEATURE...DESPITE THE WEAKER APPEARANCE OF THE FRONT IN THE
EXTENDED MODELS.

THE NORTHWEST FLOW BEHIND THAT COLD FRONT WILL HELP DROP HIGHS
FROM THE LOW 90S ON TUESDAY AND WED...BACK INTO THE UPPER 80S
THURSDAY AND LOWER 80S ON FRIDAY. DEWPOINTS WILL DROP INTO THE
LOWER 60S ON FRIDAY AS WELL...PROVIDING SOME RELIEF FROM THE HEAT
AND HUMIDITY.

.AVIATION...
ISSUED 1240 PM CDT FRI JUN 21 2013

CONVECTION TO OUR NORTH CONTINUES TO SLOWLY SINK SOUTHEAST EARLY
THIS AFTERNOON. LEADING EDGE OF COLD POOL/OUTFLOW BOUNDARY CLEARLY EVIDENT
ON KDVN REFLECTIVITY AND IS SHIFTING SOUTH AROUND 20 KTS AND IS NOW
PUSHING INTO NORTHERN KNOX AND STARK COUNTIES. IF THIS MAINTAINS
TRENDS WOULD PASS THROUGH KPIA JUST BEFORE 19Z AND KBMI AT 20Z.
BEHIND THIS BOUNDARY WINDS SHIFT NORTH GUSTING AROUND 20 KTS. LIFT
OFF THE BOUNDARY IS PRODUCING SCATTERED TSRA BEHIND IT SO HAVE
INCLUDED VCTS AFTER PASSAGE FOR KPIA/KBMI WITH A TEMP PERIOD AT
KPIA WHERE HAVE HIGHER CONFIDENCE. BOUNDARY SHOULD EVENTUALLY SLOW AND
STALL AS MAIN CONVECTIVE BATCH TO THE NORTH SHIFTS EAST...AND
10-20 KT SOUTHWEST SYNOPTIC FLOW PROVIDES RESISTANCE. SO HAVE KEPT
THIS ACTIVITY OUT OF THE TERMINALS FARTHER SOUTH/EAST. GUSTY S/SW
WINDS WILL DROP BELOW 10 KTS AFTER SUNSET...THEN PICK UP AGAIN
AFTER 14Z/SAT.
