NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 7, 2:50 PM CDT, 3 hours 23 minutes earlier.

Area forecast discussion, May 7, 2:50 PM CDT, 3 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
250 PM CDT THU MAY 7 2009

.DISCUSSION...
ISSUED 247 PM CDT THU MAY 7 2009

FORECAST PROBLEM FOR TODAY IS THE PRECIPITATION TONIGHT DUE TO THE
FRONT OUT WEST...AND THE POPS AS THE FRONT MOVES THROUGH REGION.
THEN IN THE EXTENDED...THE CONCERN IS A SYSTEM FOR THE MIDDLE OF
NEXT WEEK.

SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT

IR SATELLITE IMAGERY SHOWS TWO IMPULSES OF INTEREST. THE FIRST IS
THE ONE EXITING IL FROM CENTRAL IN TO SOUTHERN IL...THAT WAS THE
REMAINS OF MCS THAT FIRED LAST NIGHT WEST OF AREA IN PLAINS. AS
CLOUDS WITH THIS SYSTEM REMAINED OVER AREA THROUGH MORNING
HOURS...IT SERVED TO RETARD THE HEATING OVER SOUTHERN 1/2 OF IL
AND KEEP AIR IN THAT REGION MORE STABLE THAN IN NORTH HALF...AS
SHOWN IN SURFACE LIFTED INDEX IN SURFACE DATA. CLOUD DEBRIS IN IR
AND VISIBILE DATA ALSO SHOWS POSSIBLE LIFT OVER BOUNDARY FROM
SOUTHERN IL OVER CENTRAL MO INTO NORTHWEST MO.

SECOND UPPER LEVEL IMPULSE OR WAVE FROM SOUTHEAST MN TO EAST NE
WITH CLUOUDS AND SCT PCPN AHEAD OF IT OVER EAST IA. MSAS SURFACE
DATA ON AWIPS SHOWS APPARENT REINFORCING COOL POOL OUTFLOW
BOUNDARY EAST-WEST OVER NORTHER MO. CLOUDS STREETS AND STRONGER
SOUTHERLY WINDFLOW OVER EAST KS INTO NORTHWEST MO...PLUS THE 2
BOUNDARIES THAT INTERSECT IN THAT AREA...AND UPPER IMPULSE...ALL
SUPPORT BEST POSSIBLE STORM DEVELOPMENT AND SEVERE POTENTIAL IN
THAT AREA EXTENDING INTO NORTHERN MO.

WITH THE UPPER IMPULSE MOVING EAST OVER EAST IA INTO IL...HAVE
INCREASED POPS OVER NORTHERN CWA IN THE EVENING HOURS...BUT SEVERE
POTENTIAL SHOULD BE LIMITED DUE TO LOW LEVEL WIND FIELDS AND
INSTABILITY. STORMS WILL BE SCATTERED THOUGH.

AS FOR THE SOUTHWEST IA ACTIVITY...MODELS DUE BRING THAT
CONVECTION TO THE EAST...INTO THE REGION AFTER MIDNIGHT. HOWEVER
WITH THE EST LOW LEVEL INFLOW REMAINING WEST OF REGION...EXPECT
CONVECTION TO BE IN WEAKING TREND WHEN ARRIVES AND SO KEPT CHC
POPS. TRACK OF ACTIVITY FROM CORFIDI VECTOR PROGS TO BE ESE...MORE
OVER THE SOUTHERN 1/2 OF CWA AFTER MIDNIGHT.

FOR FRIDAY...THE FRONT WILL BE DRAGGING ITS WAY THROUGH THE
REGION. HOWEVER BEST LOW LEVEL INFLOW WILL REMAIN INTO THE AREA TO
THE WEST OVER MO. THAT WILL KEEP HEAVY RAIN CHANCES SOUTH OF CWA
ON FRIDAY. LIKE THE GFS SOLUTION A LITTLE BETTER ON THE QPF THAN
THE NAM. FOR FRIDAY NIGHT...THERE WILL BE ANOTHER WAVE MOVING
THROUGH THE NORTHERN PARTS OF IL...AGAIN BRINGING A CHANCE OF SOME
RAIN.

LONG RANGE...SUNDAY THROUGH THURSDAY

WITH HIGH PRESSURE BEHIND THE FRONT OVER THE REGION...DRY
CONDITIONS WILL BE THE RULE THROUGH EARLY NEXT WEEK. SOUTHERLY
FLOW DEVELOPS BY TUESDAY...WITH A CHANCE OF PCPN TUESDAY NIGHT.
FOR WED INTO THURS...A COLD FRONT WITH A SIGNIFICANT UPPER LEVEL
TROUGH WILL MOVE INTO THE AREA. CONVECTION AHEAD AND WITH THE
FRONTAL PASSAGE WILL BE IN THE AREA. EUR AND GFS MODELS SIMILAR.
HOWEVER GFS SEEMS A LITTLE FAST AND SO WENT MORE WITH A
BLEND...SIDING MORE TOWARD THE EUR TIMING.

.AVIATION...
ISSUED 1255 PM CDT THU MAY 7 2009

A WEAK COLD FRONT IN CENTRAL WI/IA HAS SCATTERED CONVECTION AHEAD
OF IT OVER THE EASTERN HALF OF IOWA. WEAK COLD FRONT WILL MOVE
INTO CENTRAL IL BY THIS EVENING AND BRING SCATTERED TO ISOLATED
CONVECTION TO CENTRAL IL AIRPORTS FROM 21Z-01Z WITH BEST CHANCE
ALONG I-74. POSSIBLE MCS MAY DEVELOP OVER MO TONIGHT AND SPREAD
EAST ACROSS CENTRAL/SOUTHERN IL OVERNIGHT AND COULD AFFECT THE
I-72 TAF SITES. HAVE SOME FOG RESTRICTING VSBYS TO 1 TO 3 MILES
OVERNIGHT AND EARLY THU MORNING BUT MID/HIGH CLOUDS FROM MCS
SHOULD KEEP DENSE FOG AWAY LIKE WHAT OCCURRED AT CMI EARLY THIS
MORNING. WSW WINDS NEAR 10 KTS THIS AFTERNOON TO BECOME LIGHT
AROUND 5 KTS TONIGHT AND THU MORNING.
