Heavy rains continued to occur across the Mid-Mississippi Valley into the Ohio Valley during the beginning part of May. In addition, spring snow melt across the Dakotas and Minnesota continued to create higher than normal river levels on the Mississippi River. The combination of the snow melt and heavy rainfall produced record breaking flooding on the Mississippi River. Numerous roads were flooded and closed as a result. Homes and businesses were flooded in the area. Many farmers lost crops or were not able to plant due to flooded fields.

UPDATE...
BAND OF THUNDERSTORMS HAVE DEVELOPED FROM THE MO BOOTHEEL
SOUTHWEST THROUGH NORTHERN AND CENTRAL ARKANSAS. THESE ARE
POSITIONED ALONG A SLOW MOVING BOUNDARY THAT WILL SAG SOUTH
TONIGHT. SOME OF THESE STORMS MAY BE SEVERE WITH LARGE HAIL BEING
THE PRIMARY THREAT GIVEN MID LEVEL LAPSE RATES OF AROUND 7 C/KM...
LI/S OF -5C NOSING INTO EAST CENTRAL ARKANSAS...AND THE PRESENCE
OF EFFECTIVE BULK SHEAR OF 50 KTS. STRONG 0-1 KM SHEAR OF 30 KTS
ALONG AND AHEAD OF THE BOUNDARY MAY PROVIDE A BRIEF TORNADO
THREAT THIS EVENING BEFORE THE BOUNDARY LAYER STABILIZES FURTHER
OVERNIGHT. THE SEVERE THREAT MAY BUILD NORTHEASTWARD ALONG THE
FRONT...COINCIDENT WITH BUILDING ELEVATED INSTABILITY.
IT APPEARS THE HEAVIEST RAIN WILL FOCUS ALONG AND NORTH OF THE
I-40 CORRIDOR...WITH A RELATIVELY LOW LIKELIHOOD OF ANY STORMS
WELL SOUTH OF THE FRONT DUE TO EML. THUS...REDUCED POPS SOUTH OF
TUPELO.
THE LLJ WILL WEAKEN LATE TONIGHT THEREBY LESSENING THE MOISTURE
CONVERGENCE ALONG THE FRONT...SO THE ORGANIZED COMPLEX OF STORMS
WILL ALSO WEAKEN BY SUNDAY MORNING. A RENEWED SURGE OF MOISTURE
SUNDAY AFTERNOON WILL SPARK THE NEXT ROUND OF HEAVY RAIN WHICH
WILL LIKELY PERSIST ALMOST CONTINUOUSLY THROUGH MONDAY NIGHT OVER
NERN AR...MO BOOTHEEL...WEST TN...AND NWRN MS. 00Z 5-DAY HPC QPF
HAS INCREASED TO WIDESPREAD 5 OR 6 INCHES NORTH OF I-40...BUT
POTENTIAL FOR 7 OR MORE INCHES EXISTS WHERE STORMS TRAIN THE MOST.
GIVEN THE HIGH LIKELIHOOD OF WIDESPREAD HEAVY RAINFALL ON WHAT IS
ALREADY A VERY SERIOUS AND WIDESPREAD FLOODING SITUATION...ISSUED
A PDS FLASH FLOOD WATCH TO HIGHLIGHT THE POTENTIALLY CATASTROPHIC
NATURE OF THE SITUATION EVOLVING OVER MOST OF THE MIDSOUTH.

PREV DISCUSSION... /ISSUED 427 PM CDT SAT APR 30 2011/
DISCUSSION...20Z SURFACE ANALYSIS PLACES A SURFACE LOW OVER NORTH
DAKOTA WITH A TRAILING COLD FRONT EXTENDING SOUTH INTO WESTERN
MISSOURI AND EASTERN OKLAHOMA. ACROSS THE MID SOUTH THIS
AFTERNOON SOUTHERLY WINDS ON THE BACKSIDE OF HIGH PRESSURE LOCATED
ACROSS THE SOUTHEAST UNITED STATES HAS BEEN ADVECTING LOW LEVEL
MOISTURE UP FROM THE GULF OF MEXICO. KNQA WSR-88D RADAR TRENDS
SHOW ISOLATED TO SCATTERED SHOWERS WITH PERHAPS AN ISOLATED
THUNDERSTORM MAINLY WEST OF THE MISSISSIPPI RIVER AS OF AFTERNOON
DISCUSSION TIME. AS OF 3 PM CDT...TEMPERATURES ARE IN THE 70S AT
MOST LOCATIONS. SEVERE THUNDERSTORM POTENTIAL TONIGHT AND SUNDAY
AND HEAVY RAINFALL POTENTIAL TONIGHT THROUGH TUESDAY ARE THE
PREDOMINANT CONCERNS IN THIS AFTERNOON/S FORECAST PACKAGE.
SHORT TERM...(TONIGHT THROUGH TUESDAY)...WRF/GFS/ECMWF MODELS
ALL IN DECENT AGREEMENT WITH A COLD FRONT DROPPING INTO THE MID
SOUTH TONIGHT INTO SUNDAY AND BECOMING QUASI-STATIONARY ACROSS THE
MID SOUTH SUNDAY AS THE SURFACE FRONT BECOMES NEARLY PARALLEL TO
SOUTHWEST UPPER LEVEL FLOW ALOFT.
SOMEWHAT FAVORABLE UPPER LEVEL DIVERGENCE PRODUCED ON THE SOUTHERN
PERIPHERY OF A 120 KT JET STREAK...MODERATE TO STEEP 700-500 MB
LAYER MID LEVEL LAPSE RATES BETWEEN 6.5 TO 8 C/KM...MOST UNSTABLE
CAPE VALUES RANGING BETWEEN 1500 TO 2500 J/KG...LI/S BETWEEN -4 TO
-6...AND 0-6 KM BULK SHEAR VALUES BETWEEN 40 TO 50 KTS...SUGGEST A
POTENTIAL FOR A FEW THUNDERSTORMS TO BECOME SEVERE TONIGHT AND
SUNDAY WITH DAMAGING WINDS AS THE PRIMARY SEVERE WEATHER THREAT
AND HAIL AS A SECONDARY SEVERE WEATHER THREAT.
IN ADDITION TO THE SEVERE THUNDERSTORM THREAT...A SURFACE LOW WILL
DEVELOP ACROSS THE LOWER MISSISSIPPI VALLEY WITH SEVERAL MID LEVEL
SHORTWAVE TROUGHS EMBEDDED WITHIN SOUTHWEST FLOW ALOFT MOVING
ALONG THIS QUASI-STATIONARY BOUNDARY. ALSO...PRECIPITABLE WATER
VALUES WILL REMAIN BETWEEN 1.8 TO 2 INCHES. 12Z ECMWF/GFS MODELS
ARE IN BETTER AGREEMENT WITH CURRENT FORECAST THAN THE 12Z WRF
WHICH LOWERED AND SHIFTED 2 DAY RAINFALL AMOUNTS FURTHER NORTH.
STILL THINK 3 TO 5 INCH RAINFALL AMOUNTS WITH LOCALIZED AMOUNTS UP
TO 7 INCHES ARE STILL REASONABLE IN CURRENT FLASH FLOOD WATCH AND
FORECAST. EVENING AND MIDNIGHT SHIFT WILL MAKE ANY NECESSARY
ADJUSTMENTS TO HEADLINES AND FORECAST AS NEEDED.
LONG TERM...(TUESDAY NIGHT THROUGH SATURDAY)...12Z ECMWF IN
BETTER AGREEMENT WITH PREVIOUS FORECASTS THAN THE 12Z GFS WHICH
QUICKLY MOVES RAIN OUT OF THE MID SOUTH TUESDAY NIGHT. AS A
RESULT...RAISED LINGERING RAIN CHANCES FOR TUESDAY EVENING BASED
ON LATEST MODEL TRENDS. HIGH PRESSURE WILL BUILD BACK INTO THE
AREA FOR WEDNESDAY AND THURSDAY. HOWEVER...ANOTHER MID LEVEL
SHORTWAVE WILL BRING AN ADDITIONAL CHANCE FOR SHOWERS AND
THUNDERSTORMS TO THE AREA THURSDAY NIGHT AND FRIDAY.
