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.

NWS Memphis, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 29, 9:47 PM CDT, 51 minutes earlier.

Area forecast discussion, Mar 29, 9:47 PM CDT, 51 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MEMPHIS TN
947 PM CDT TUE MAR 29 2011

.UPDATE...
RAIN AND ISOLATED SEVERE HAIL EVENT UNDERWAY ACROSS THE MIDSOUTH
AT MIDEVENING. GOES WATER VAPOR IMAGERY SHOWED A VIGOROUS
SHORTWAVE LIFTING EAST INTO KS...UNDERCUT A DIFFLUENT UPPER LEVEL
FLOW ACROSS THE LOWER MS RIVER VALLEY. THIS DIFFLUENT FLOW WAS
ENHANCING ISENTROPIC LIFT OVER A STABLE LAYER EXTENDING UP TO
850MB OVER NORTHEAST AR... AND JUST OFF THE SURFACE OVER NORTHEAST
MS. THIS AIR WAS QUICKLY BECOMING BUOYANT...WITH CAPE TO 500 J/KG
NEAR I40... AND 1000 J/K OVER NORTH MS. MIDLEVEL LAPSE RATES TO 8
C/KM AREAWIDE WERE ENHANCING THE HAIL POTENTIAL.

EXPECT AN INCREASE IN RAIN COVERAGE INTO THE EARLY MORNING...
MAINLY EAST OF THE MS RIVER... AS A SOUTHWARD EXTENSION OF THE
MIDPLAINS VORT AXIS ROTATES THROUGH. THIS SHORTWAVE WILL HELP
ERODE WHAT/S LEFT THE WEAK ELEVATED CONVECTIVE INHIBITION.
OVERNIGHT HAIL POTENTIAL MAY WANE SOMEWHAT...WITH SLOWLY MODERATING
MIDLEVEL LAPSE RATES AND ELEVATED INSTABILITY. OTHER POSSIBLE
NEGATING FACTOR FOR OVERNIGHT SEVERE POTENTIAL IS THE DEVELOPING
LARGE MCS TAKING SHAPE OVER CENTRAL AND SOUTHERN MS. NORTHEAST
MS WILL BE IN CLOSE ENOUGH PROXIMITY OVERNIGHT TO INTERCEPT SOME
OF THE NORTHEASTWARD MOVING CELLS OFF THE MORE ORGANIZED CONVECTION
OVER CENTRAL MS.

.PREV DISCUSSION... /ISSUED 641 PM CDT TUE MAR 29 2011/

UPDATE...

UPDATED FOR 00Z AVIATION DISCUSSION.

PREV DISCUSSION... /ISSUED 323 PM CDT TUE MAR 29 2011/

DISCUSSION...
ELEVATED CONVECTION IS ONGOING ACROSS NORTHEAST ARKANSAS...SOUTH
MISSOURI...AND PORTIONS OF WEST TENNESSEE. STILL NO REPORTS OF
SMALL HAIL ACROSS ANY OF OUR FORECAST AREA NOR UPSTREAM ACROSS
NORTH ARKANSAS. 5-7 HUNDRED MB LAPSE RATES ARE BETWEEN 7 AND 8
DEGREES C/KM. LAPSE RATES SHOULD BE AT THEIR STEEPEST NORTH OF
INTERSTATE 40 RIGHT NOW...BUT ONLY WEAKEN SLIGHTLY...BY AT MOST A
DEGREE THROUGH MIDNIGHT. FARTHER SOUTH...7.25 TO 7.75 DEGREE LAPSE
RATES WILL REMAIN IN PLACE A BIT LONGER. EVEN THOUGH LAPSE RATES
ARE EXPECTED TO WEAKEN ACROSS NORTHERN AREAS...PROXIMITY TO AN
APPROACHING SHORTWAVE TROUGH AND VORT MAX SHOULD KEEP THE THREAT
OF AT LEAST SMALL HAIL IN THE AREA WELL INTO THE OVERNIGHT HOURS.
THIS SYSTEM IS SIMILAR TO THE PREVIOUS SYSTEM WHICH BROUGHT
WIDESPREAD HAIL TO THE MIDSOUTH. THE TWO MAIN DIFFERENCES SHOULD
OFFSET EACH OTHER. THE WARM FRONT IS FARTHER SOUTH BUT THE UPPER
LEVEL DYNAMICS ARE STRONGER. IF A SURFACE LOW DEVELOPS ALONG AN
INVERTED TROUGH IN EAST CENTRAL MISSISSIPPI AS THE GFS
SUGGESTS...WIND COULD BECOME A BIGGER THREAT IN NORTHERN
MISSISSIPPI AROUND MIDNIGHT.

EVERYTHING STILL LOOKS ON TRACK FOR ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS THURSDAY NIGHT INTO FRIDAY. MOISTURE LOOKS LIMITED
DURING THIS TIME FRAME HOWEVER IN HIGHLY AMPLIFIED NORTH WESTERLY
FLOW...DYNAMICS SHOULD BE SUFFICIENT TO RESULT IN AT LEAST A FEW
STRONG THUNDERSTORMS.

THE WEEKEND LOOKS MUCH NICER AS A RIDGE ALONG THE PACIFIC COAST
SHIFTS INTO THE PLAINS SHUNTING THE MEAN STORM TRACK TO THE EAST
OF OUR AREA. THE RIDGE WILL CONTINUE TO SHIFT EAST SATURDAY
DOMINATING THE WEATHER ACROSS THE MIDSOUTH FOR MOST OF THE
WEEKEND. HIGHS WILL CLIMB INTO THE 70S EACH DAY...WITH 1000-500 MB
THICKNESSES SUPPORTIVE OF LOW TO MIDDLE 80S IN SOUTHWESTERN
PORTIONS OF THE FORECAST AREA SUNDAY AFTERNOON. INCREASING CLOUD
COVER MAY PREVENT US FROM BECOMING THAT WARM.

EARLY NEXT WEEK...A MORE PROTOTYPICAL SPRING WEATHER SYSTEM LOOKS
TO BE IN THE WORKS. UNLIKE THE PAST 2-3 EVENTS THIS SYSTEM LOOKS
LIKE IT MAY HAVE BOTH DYNAMIC AND THERMAL ENERGY WORKING IN ITS
FAVOR. IN ADDITION MULTIPLE DAYS OF SOUTHERLY FLOW AHEAD OF THE
FRONT SHOULD ENSURE ADEQUATE MOISTURE IN IN PLACE.

30/SIRMON

&&

.AVIATION...

00Z TAF SET

A BAND OF SHOWERS AND THUNDERSTORMS HAS BEEN PUSHING ACROSS THE
MIDSOUTH NORTH OF I-40 DURING THE PAST SEVERAL HOURS. GENERALLY
IFR CONDITIONS OR LOWER HAVE BEEN REPORTED IN THESE AREAS...WITH
VFR OR MVFR CONDITIONS FURTHER SOUTH. THINK MORE SHOWERS AND
THUNDERSTORMS WILL DEVELOP ACROSS THE REST OF THE AREA..NAMELY
ALONG AND SOUTH OF KMEM-KMKL BETWEEN 01Z-04Z...AND CONTINUING
THROUGH 08-12Z.

CEILINGS ARE EXPECTED TO DETERIORATE TO IFR TONIGHT AND CONTINUE
AT IFR LEVELS INTO MID MORNING WEDNESDAY WITH IMPROVING CONDITIONS
THEREAFTER.
