.PREV DISCUSSION... /ISSUED 1043 PM CDT MON MAY 2 2011/

UPDATE...
EXPIRATION OF THE FLASH FLOOD WATCH MOVED FORWARD TO 18Z / 1PM CDT
TUESDAY... BASED ON EXIT TIMING OF HEAVIER RAINFALL.

SIGNIFICANT RIVER AND AREAL FLOODING TO CONTINUE.

PWB

&&

.PREV DISCUSSION... /ISSUED 947 PM CDT MON MAY 2 2011/

UPDATE...
HEAVY RAIN THREAT WILL CONTINUE THROUGH THE OVERNIGHT... LIKELY
TAPERING OFF OVER NORTHEAST AR TOWARD MORNING. SHOWERS AND
THUNDERSTORMS EMBEDDED IN THE ELEVATED WARM CONVEYOR BELT WILL
FINALLY SHIFT EAST OF THE MIDSOUTH BY LATE TUESDAY AFTERNOON. A
FEW SHOWERS OR SPRINKLES WILL STILL BE POSSIBLE... ASSOCIATED WITH
WITH THE PASSAGE THE UPPER TROF AXIS.

FORECAST WAS UPDATED EARLIER TO TRIM THUNDER CHANCES OVER NORTHEAST
AR...THE MO BOOTHEEL AND NORTHWEST TN TONIGHT AND EARLY TUESDAY. OTHER
CHANGES INCLUDED ADJUSTMENTS TO AFTERNOON POPS AND INSERTION OF
WEDNESDAY AND THURSDAY MORNINGS.

PWB

&&

.PREV DISCUSSION... /ISSUED 338 PM CDT MON MAY 2 2011/

DISCUSSION...
HEAVY RAIN RESULTING IN AREAL FLOODING...FLASH FLOOD AND ONGOING
RIVER FLOODING REMAIN THE MAIN AREAS OF CONCERN THIS AFTERNOON
ACROSS THE MIDSOUTH. MORE ON THE HYDRO PROBLEM BELOW. WE ARE ALSO
DEALING WITH THE THREAT OF A FEW THUNDERSTORMS IN PORTIONS OF
NORTHEAST MISSISSIPPI AND PORTIONS OF WEST TENNESSEE. A TROUGH
WILL ROTATE OUT OF THE PLAINS THIS EVENING...BUT LIKELY A BIT
LATER IN THE DAY SO IT MAY NOT BE COINCIDE WITH THE BEST DAYTIME
HEATING LIKE YESTERDAY. NEVERTHELESS A VERY UNSTABLE AIRMASS IS
IN PLACE ACROSS MUCH OF NORTHEAST MISSISSIPPI. DEW POINTS AT
TUPELO AND CORINTH REMAIN IN THE MIDDLE 60S...BUT DROP OFF QUICKLY
FARTHER NORTH INTO TENNESSEE. 0-3 KM HELICITY IS
RESPECTABLE...AROUND 150 M/S^2...WITH 30-40 KNOTS OF SHEAR.
SOUNDINGS SHOW A STRONG CAP AT BIRMINGHAM...BUT QUITE A BIT WEAKER
AT JACKSON...AND LAPSE CIN IS NEAR ZERO NORTHWEST OF COLUMBUS.

OVERNIGHT...THE SEVERE THREAT WILL DIMINISH QUICKLY BUT RAIN WILL
CONTINUE. A FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH THE NIGHT
INTO TOMORROW. RAIN WILL FINALLY TAPER OFF FROM WEST TO EAST
TOMORROW. AS A HIGHLY AMPLIFIED TROUGH SHIFTS INTO ALABAMA.

WE WILL FINALLY GET A SERIES OF DRY DAYS WEDNESDAY INTO NEXT
WEEKEND. HOWEVER OUR FLOOD CONCERNS ARE FAR FROM OVER. AREA
RIVERS WILL CONTINUE TO RISE...AND AS THE MISSISSIPPI RIVER
RISES...TRIBUTARIES WILL BEGIN TO BACK UP AS WATER HAS NO PLACE TO
GO. TEMPERATURES WILL CLIMB TO NEAR SEASONABLE READINGS BY THE END
OF THE WORK WEEK. A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
WILL RETURN TO THE AREA BY THE WEEKEND.

.HYDROLOGY...

FOUR TO TWELVE INCHES OF RAIN HAS ACCUMULATED SINCE SUNDAY WITH
THE GREATEST ACCUMULATIONS ALONG THE INTERSTATE 40 CORRIDOR. FLASH
FLOODING...AREAL FLOODING FROM POOR DRAINAGE AND SATURATED SOILS
AS WELL AS RIVER FLOODING ALL REMAIN VERY HIGH CONCERNS ACROSS
THE MIDSOUTH. AN ADDITIONAL 2-4 INCHES OF RAIN IS LIKELY TONIGHT
INTO EARLY TOMORROW ACROSS GENERALLY THE SAME LOCATION. THE
MISSISSIPPI RIVER WILL LIKELY APPROACH...POSSIBLY EXCEED RECORD
LEVELS AROUND THIS TIME NEXT WEEK. FLOODING OF THIS MAGNITUDE HAS
NOT BEEN OBSERVED IN THE MEMPHIS AREA IN MOST OF OUR
LIFETIMES...NEARLY 75 YEARS. ALTHOUGH WE HAVE ADVANCED COMPUTER
MODELS TO HELP US DETERMINE AREAS ARE PRONE TO FLOODING THE FEAR
OF THE UNKNOWN IS VALID AND CITIZENS SHOULD PAY CLOSE ATTENTION
ANY WATCHES...WARNINGS OR STATEMENTS ISSUED BY THE NATIONAL
WEATHER SERVICE AS WELL AS OTHER OFFICIAL AGENCIES.

BASED ON DISCUSSION WITH THE CORPS OF ENGINEERS...THEY DO NOT FEEL
LIKE ANY UPSTREAM OPERATIONS AT THE BIRD POINT LEVEE WILL HAVE A
DIRECT IMPACT AT MEMPHIS...AND ONLY MINIMAL IMPACT IF ANY UPSTREAM
AT TIPTONVILLE AND CARUTHERSVILLE. THE RELEASE OF WATER FROM
BEHIND THE LEVEE WILL SIMPLY NOT ADD ANY ADDITIONAL WATER TO THE
RIVER SYSTEM...JUST CHANGE THE PATH THAT THE WATER TAKES GETTING
INTO THE RIVER SYSTEM. THANKS TO THE CORPS FOR A FANTASTIC
DISCUSSION EARLIER TODAY.

.AVIATION...
06Z TAF CYCLE

WIDESPREAD IFR CIGS AND SOME IFR/MVFR VISIBILITIES EXPECTED
THROUGH TONIGHT WITH OCCASIONAL SHOWERS AND ISOLATED
THUNDERSTORMS. CIGS EXPECTED TO IMPROVE MARKEDLY SOMETIME TUESDAY
AFTERNOON...BUT CONFIDENCE OF EXACTLY WHEN STILL REMAINS LOW.
NORTH WINDS 10 TO 15 KTS WILL GRADUALLY DECREASE TO NORTHWEST 5 TO
10 KTS BY TUESDAY AFTERNOON AND BECOME LIGHT/VARIABLE TUESDAY
EVENING. AS SKIES CLEAR AND WINDS DIMINISH...FOG IS EXPECTED TO
BECOME FAIRLY WIDESPREAD...ESPECIALLY TOWARD KMKL AND KTUP.
