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 12, 4:12 PM CDT, 40 minutes earlier.

Area forecast discussion, Jun 12, 4:12 PM CDT, 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
412 PM CDT SAT JUN 12 2010

.DISCUSSION...
ISSUED 412 PM CDT SAT JUN 12 2010

COMPLEX SITUATION EVOLVED OVER THE CWA THIS AFTERNOON. MCS MOVED
OUT OF IOWA EARLY THIS AFTERNOON...MOVING INTO JUICY UNCAPPED AIR
WITH CAPE VALUES OVER 3500 J/KG IN SOME AREAS. THUNDERSTORMS
RAPIDLY INCREASED AHEAD OF THE ORIGINAL LINE OF MCS STORMS AND THE
LINE CURRENTLY IS GENERALLY BETWEEN I-55 AND I-57. EARLIER HAD TO
ISSUE A HEAT ADVISORY FOR AREAS SOUTH OF I-70 AS WIDESPREAD VALUES
OVER 100F HAD DEVELOPED BY EARLY AFTERNOON. AREAS FURTHER NORTH IN
CENTRAL ILLINOIS DID GET NEAR 100F HEAT INDEX AT TIMES BEFORE THE
INCREASED CLOUDS ARRIVED.

THUNDERSTORM THREATS OVER THE NEXT FEW DAYS CONSTITUTE THE MAIN
FORECAST CHALLENGE FOR THIS PACKAGE...ALONG WITH ASSOCIATED HEAVY
RAIN POTENTIAL.

SHORT TERM...TONIGHT THROUGH TUESDAY...

18Z SURFACE CHART WAS COMPLICATED BY THE MCS...BUT THE MAIN COLD
FRONT GENERALLY EXTENDED FROM EASTERN MICHIGAN THROUGH CENTRAL
IOWA...THEN SOUTHWEST INTO KANSAS. GENERAL CONSENSUS AMONG THE
MODELS WOULD BE TO BRING IT INTO CENTRAL ILLINOIS SOMETIME ON
SUNDAY...MOST LIKELY REACHING I-72 DURING THE EVENING.

MOST OF THE RAIN ACTIVITY ACROSS THE CWA TONIGHT SHOULD BE IN THE
EVENING. HOWEVER...MAY BEGIN TO SEE RENEWED MCS ACTIVITY MOVE IN
LATE. REDEVELOPMENT ON SUNDAY MAY HINGE ON WHERE ANY RESIDUAL
BOUNDARIES SET UP...AS WELL AS HOW WELL THE ATMOSPHERE CAN
DESTABILIZE WITH ANY CLOUD COVER AROUND. WENT WITH 50 PERCENT POPS
OVER MOST OF THE AREA SUNDAY INTO SUNDAY NIGHT.

PASSAGE OF THE FRONT SHOULD SLOW DOWN SUNDAY NIGHT INTO
MONDAY...AS ANOTHER WAVE DEVELOPS SOUTHWEST OF HERE AND MOVES
NORTHEAST INTO THE GREAT LAKES. WILL NEED TO KEEP THUNDER CHANCES
GOING MONDAY AND TUESDAY. SEVERE WEATHER THREAT IS MORE MUDDLED
DURING THIS PERIOD...BUT IF ANY OCCURRED...THE SOUTHERN CWA WOULD
BE MORE LIKELY AS IT REMAINS SOUTH OF THE BOUNDARY. LINGERING RAIN
SHOULD FINALLY END TUESDAY NIGHT...AS THE FRONT FULLY PUSHES
THROUGH THE CWA.

LONG TERM...WEDNESDAY THROUGH SATURDAY...

UPPER RIDGE BEGINS TO BUILD AGAIN ACROSS THE REGION AFTER
MIDWEEK...WITH TEMPERATURES NEAR 90 LIKELY AGAIN THURSDAY AND
FRIDAY. NEXT SHORTWAVE IS SLATED TO ARRIVE SOMETIME ON
FRIDAY...ALTHOUGH THERE IS SOME DISAGREEMENT IN THE SPEED OF
THIS...WITH THE ECMWF THE FASTER SOLUTION. CURRENTLY WILL ONLY GO
WITH SLIGHT CHANCE POPS FRIDAY AND FRIDAY NIGHT UNTIL SOME
AGREEMENT BEGINS TO TAKE SHAPE.

...SEVERE THUNDERSTORMS WITH INTENSE LIGHTNING MOVING THROUGH
EASTERN ILLINOIS...

STRONG TO SEVERE THUNDERSTORMS CONTINUE TO EXPAND IN COVERAGE AS
THEY MOVE ACROSS EASTERN ILLINOIS. ONE AREA WILL AFFECT LOCATIONS
FROM CHAMPAIGN TO MARSHALL EASTWARD THROUGH 530 PM. A SECOND LINE
OF STRONG TO SEVERE STORMS WILL AFFECT SOUTHEAST ILLINOIS BETWEEN
5 PM AND 630 PM. DAMAGING WINDS ARE LIKELY WITH BOTH OF THESE
LINES OF STORMS...AS WELL AS AREAS OF FLOODING DUE TO RAPID
RAINFALL ACCUMULATIONS OF 1 TO 3 INCHES IN LESS THAN AN HOUR.

ADDITIONALLY...BOTH OF THESE LINES OF STORMS ARE PRODUCING INTENSE
LIGHTNING. REMEMBER THAT LIGHTNING STRIKES MAY OCCUR WELL BEFORE
AND AFTER THE PASSAGE OF THE MAIN LINE OF STORMS. PEOPLE WITH
OUTDOOR ACTIVITIES SHOULD TAKE COVER IN A STURDY SHELTER AHEAD OF
THE ARRIVAL OF THE STORMS.
