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.

Area forecast discussion, May 18, 2:30 PM CDT, 2 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
230 PM CDT THU MAY 18 2000

A NEW TORNADO WATCH HAS BEEN ISSUED...ROUGHLY WEST OF A LINE FROM
BLOOMINGTON TO DECATUR TO TAYLORVILLE UNTIL 9 PM. INGREDIENTS REMAIN
FAVORABLE FOR THE RAPID DEVELOPMENT OF SUPERCELLS WITH TORNADOES AND
LARGE HAIL IN CENTRAL ILLINOIS. SEVERAL BOUNDARIES LYING AROUND...
INCLUDING ONE SOUTHWARD MOVING ONE NEAR I-80...AND SEVERAL SMALLER
ONES IN EAST CENTRAL ILLINOIS DUE TO LATE MORNING SEVERE T-STORMS
...WILL ENHANCE THE SUPERCELLS CAUSING THEM TO BECOME TORNADIC
QUICKLY. WILL OBVIOUSLY HIGHLIGHT THE THREAT OF SEVERE WEATHER THIS
EVENING IN WRN HALF OF FORECAST AREA (CURRENTLY IN THE WATCH)...AND
MENTION SEVERE THREAT CONTINUING IN ERN HALF OF AREA LATE EVENING
AND TONIGHT.

WATER IMAGERY INDICATED AN UPR LOW IN SRN IA...WHICH IS FORECAST TO
SHEAR ENE IN RESPONSE TO A NRN STREAM TROUGH DIGGING FROM JUST EAST
OF HUDSON BAY TO THE CANADIAN MARITIMES. A NEARLY ZONAL FLOW WILL
DEVELOP ACROSS THE NRN U.S. ON FRIDAY AS A RESULT. VORTICITY SHEARING
ACROSS NRN IL FRIDAY...AND A SURFACE LOW TRACKING TOWARD WCENT IND
BY FRI MORNING...WILL RESULT IN LINGERING LIGHT RAIN IN THE NRN
HALF OF ILX FORECAST AREA. LOW LEVEL COLD AIR ADVECTION AND PLENTY
OF CLOUDS WILL PRODUCE COOL TEMPS IN THE MIDDLE TO UPPER 60S AS WELL.
THE FRONTAL BOUNDARY IS EXPECTED TO MOVE SOUTH OF THE OH VALLEY BY
FRIDAY NIGHT...ALLOWING ANTICYCLONIC FLOW TO DEVELOP AND PARTIAL
CLEARING. IF SKIES COMPLETELY CLEAR FRIDAY NIGHT WE MAY HAVE FOG TO
DEAL WITH SAT MORNING...BUT WILL ADDRESS THAT LATER.

CURRENT FORECAST FOR THE WEEKEND INDICATES DRY WEATHER ACROSS CENT
AND SE IL. AVN MODEL IS VERY VIGOROUS IN STRENGTHENING A SRN STREAM
WAVE SATURDAY...CAUSING A LOW TO MOVE ALONG THE FRONT FROM NE TEXAS
INTO THE LOWER OH VALLEY BY SAT NIGHT. THE AVN FORECASTS ALL KINDS
OF OVERRUNNING RAINFALL TO PUSH INTO SRN AND CENT IL SATURDAY. I
BELIEVE THAT THE AVN IS OVERDOING THE NRN EXTENT OF THE
PRECIPITATION AND IS TOO FAR NORTH WITH THE TRACK OF THE LOW. WILL
ONLY INTRODUCE RAIN FOR LOCATIONS ALONG AND SOUTH OF I-70 AT THIS
TIME...WITH PARTLY/MOSTLY CLOUDY CONDITIONS IN CENT IL.
