.DISCUSSION...
/321 AM CDT SUN JUN 19 2011/
STRONG COLD POOL HAS DEVELOPED OVER SOUTHWEST MISSOURI WHICH HAS
BEGUN TO ACCELERATE THE MCS OVER THE SOUTHERN CWA. MAINLY ELEVATED
STORMS CONTINUE BEHIND THE MCS OVER MUCH OF MISSOURI IN A LARGE
AREA OF MUCAPES BETWEEN 500-2000 J/KG ON NOSE OF A BROAD LOW LEVEL
JET. THINK THAT ANY REMAINING SEVERE WEATHER BEHIND TO LOW WILL BE
ISOLATED AS THE LOW LEVEL JET BEGINS TO VEER. RUC IS SHOWING
MOISTURE CONVERGENCE LINGERING OVER THE EASTERN CWA THROUGH
15Z...SO HAVE RAISED POPS OVER SOUTHERN ILLINOIS THROUGH MID
MORNING AND BACKED THEM OFF BY LATE MORNING. FLASH FLOOD
WISE...WILL LET THE WATCH EXPIRE AT 7 AM AS MCS IS ACCELERATING
EASTWARD AND REMAINING HEAVIER CORES WILL BECOME ISOLATED IN
NATURE.
HAVE JUST SLIGHT CHANCES FOR THUNDERSTORMS THIS AFTERNOON. EXTREME
INSTABILITY WILL DEVELOP OVER THE REGION AS STEEP LAPSE RATES
OVERRIDE LOWER 70S DEWPOINTS. CAN NOT RULE THAT THERE WILL BE
REDEVELOPMENT ON RESIDUAL BOUNDARY LEFT BY THE MCS...WARM LAYER
SEEN ON FORECAST SOUNDINGS BETWEEN 800-700MB LOOKS LIKE IT WILL
LIMIT COVERAGE THIS AFTERNOON. WARM FRONT WILL BEGIN TO MOVE
NORTH OF THE AREA TONIGHT IN RESPONSE TO DEEPENING WRN CONUS
TROUGH. HAVE CHANCE POPS UP IN NORTHERN AND EASTERN CWA TONIGHT
ALONG THE RETREATING FRONT WITH DRY WEATHER EXPECTED IN THE WARM
SECTOR UNDER THE STRONG CAP ON MONDAY. BY LATE MONDAY NIGHT AND
TUESDAY...STRONG UPPER TROUGH WILL CAUSE A WEAKENING OF THE
CAP...SO HIGH CHANCE OF LIKELY POPS STILL LOOK GOOD. RISK OF
SEVERE WEATHER WILL ONCE AGAIN EXIST TUESDAY AND TUESDAY NIGHT AS
THE COLD FRONT MOVES THROUGH MO/IL.

KANOFSKYFlash Flood, Bond
- When
- June 19, 3:30 AM CST to 8:30 AM CST
- Where
- Bond County, 1.48 mi SSE of Hamburg to 2.63 mi N of Mulberry Grove
- Cause
- Heavy Rain
- Reported by
- Newspaper
- Coordinates
- 38.850, -89.260
Up to four inches of rain fell onto already saturated soils causing flash flooding. Numerous roads were flooded including Illinois Routes 140 and 127 in places. West Ayers Road at Poke Avenue, just east of Illinois Route 127, had to be completely closed to traffic when the road was washed away when a large culvert gaveaway. Several vehicles became stranded, especially in the Greenville area, so water rescues had to be performed. No injuries were reported because of this.
- Flash Flood
- Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
