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 Little Rock, AR wrote its last area forecast discussion before this severe thunderstorm warning went out at May 12, 6:58 PM CDT, 1 hour 44 minutes earlier.
Area forecast discussion, May 12, 6:58 PM CDT, 1 hour 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 658 PM CDT THU MAY 12 2011 .AVIATION... AS OF 00Z...A COLD FRONT WAS SITUATED NORTH-SOUTH ACROSS EASTERN OKLAHOMA. SCT TSTMS WERE DEVELOPING OUT AHEAD OF THIS FRONT OVER ERN OKLAHOMA AND FAR WRN ARKANSAS...WITH ISOLATED SMALL STORMS AS FAR EAST AS KHOT AND KLIT VICINITY. EXPECT STORMS TO GRADUALLY EXPAND IN COVERAGE AND SHIFT EAST THROUGH THE NIGHT AS THE COLD FRONT MOVES EAST. KPBF AND KLLQ WILL BE THE LAST TO SEE ANY TSTM ACTIVITY AND LIKELY NOT UNTIL 05Z OR SO. AM NOT SURE EXACTLY WHEN STORMS WILL CLEAR SITES FOR GOOD SO HAVE GONE WITH PREVAILING VCTS FOR SEVERAL HOURS...WITH A TEMPO GROUP FOR 2SM VSBY AND -TSRA. BEHIND THE FRONT SKIES SHOULD RETURN TO VFR LEVELS AND WINDS VEER AROUND TO THE WEST. WILL LEAVE CENTRAL AND SOUTHERN SITES AT VFR LEVELS FROM ESSENTIALLY 10Z ONWARD. AT KBPK AND KHRO HOWEVER...AFTER A PERIOD OF VFR CIGS BETWEEN 08-15Z...WNW FLOW WILL BRING MVFR CIGS BACK TO THOSE TERMINALS BY MIDDAY. && .PREV DISCUSSION... /ISSUED 301 PM CDT THU MAY 12 2011/ SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT... TWO STORIES TO BE TOLD IN THE SHORT TERM. STORY NUMBER ONE IS THE POTENTIAL FOR ACTIVE WEATHER THIS AFTERNOON THROUGH FRIDAY AFTERNOON. STORY NUMBER TWO IS THE APRIL-LIKE TEMPERATURES IN STORE FOR THE WEEKEND. STORY NUMBER 1...THIS AFTERNOON THROUGH FRIDAY AFTERNOON... THE PICTURE IS STILL A BIT HAZY IN REGARDS TO CONVECTION THIS AFTERNOON/EVENING AS A WEAK MID LVL WAVE CONTS TO MOVE TOWARD THE NATURAL STATE FROM THE SW. ACCOMPANYING THE WAVE IS AN UPR JET IMPULSE THAT IS ROTATING AROUND A CLOSED UPR LOW THAT IS SITUATED IN NRN KS ATTM. BROAD SPEED/DIRECTIONAL DIVERGENCE ATOP AN INCREASINGLY UNSTABLE AIRMASS CHARACTERIZED BY MLCAPE VALUES AOA 2500 J/KG SHOULD ALLOW FOR CONVECTIVE DVLPMNT THIS AFTERNOON OVER ERN OK. IT REMAINS QUESTIONABLE THE EXACT EVOLUTION OF CONVECTION THIS AFTERNOON AS CLOUD COVER AHEAD OF THE DRYLINE HAS MUDDLED THINGS A BIT. LATEST RUC FCST SOUNDINGS ARE SHOWING A BIT MORE CAPPING THAN PREVIOUSLY INDICATED OVER CEN PARTS OF AR THIS AFTERNOON WHICH COULD LIMIT COVERAGE OF AFTERNOON STORMS. HAVE TRENDED POPS DOWN THROUGH 00Z IN LIGHT OF THIS INFORMATION. BEST GUESS AT THIS TIME IS THAT DEEP CONVECTION WILL INITIATE IN ERN OK OR THE ARKLATEX REGION BTW 21-00Z AS LFC/S HAVE FALLEN BELOW 1000M IN THESE AREAS. STORMS WILL THEN MOVE ENE INTO THE STATE WITH A RELATIVELY SLOW STORM MOTION OF 15-25KTS INITIALLY. THE BEST SVR CHCS FOR THE KLZK CWA WILL LIKELY BE BTW 00Z-06Z WITH DMG WINDS AND LARGE HAIL THE MAIN THREATS. AN ISOLATED TORNADO CANNOT BE RULED OUT GIVEN LOW LCL HEIGHTS BUT ANY THREAT WILL BE LOCALIZED ALONG WEAK SFC BNDRYS. BEGINNING AROUND 03-04Z...SVR WIND CHCS WILL WANE AS THE NOCTURNAL INVERSION SETS UP. UNLIKE THE APRIL 2011 NIGHTTIME EVENTS...THE ENVIRONMENT MAY NOT BE AS WELL MIXED DUE TO LACK OF LOW LVL FLOW AND THE NOCTURNAL INVERSION SHOULD THEREFORE BE STRONGER AND MORE INHIBITIVE TO DMG WIND GUSTS. AFTER LINGERING RAIN CHCS THROUGH EARLY FRIDAY...ANOTHER LINE OF STORMS COULD FIRE OVER THE ERN SECTIONS OF THE CWA EARLY FRI AFTERNOON AS THE COLD FRONT SWEEPS EAST. THIS ACTIVITY SHOULD BE MAINLY S AND E OF THE I30-US67 CORRIDOR. WEAKENING DYNAMICS SHOULD MAKE FOR ONLY A MARGINAL SVR THREAT FRI AFTERNOON. STORY NUMBER 2...FRIDAY NIGHT THROUGH SUNDAY NIGHT... AFTER THE COLD FRONT SWEEPS THROUGH ON FRIDAY...THE WEEKEND LOOKS TO BE DOMINATED BY CLOUDY MORNINGS AND PARTLY SUNNY AFTERNOONS AS LOW LVL MSTR ALLOWS DIURNAL LOW STRATUS TO FORM DURING THE OVERNIGHT. THE EXCEPTION TO THIS MAY BE IN FAR NRN AND NERN AR WHERE SKIES SHOULD STAY MAINLY CLOUDY MOST OF THE WEEKEND DUE TO PROXIMITY TO THE UPR LOW. TEMPS WILL RUN 10-15 DEGREES BELOW NORMAL WITH HIGHS IN THE 60S TO LOW 70S AND LOWS IN THE 40S AND 50S. CLOUD COVER SHOULD PRECLUDE ANY 30S FOR OVERNIGHT LOWS...BUT IT CAN/T BE RULED OUT IN THE COOLEST PLACES SUN AND MON MORNING. LONG TERM...MONDAY THROUGH THURSDAY I DOUBT FEW PEOPLE WOULD HAVE ANY COMPLAINTS ABOUT THE EXTENDED PERIOD. ASIDE FROM THE IFLUENCE OF THE UPPER LOW INVOF THE MID SOUTH AND OHIO VALLEY BRINGING SLIGHT CHANCES OF SHOWERS TO THE EAST EARLY ON...STRONG NORTHERLY AND NORTHWEST FLOW WILL KEEP COOL AIR OVER THE REGION THROUGH THE PERIOD. HIGH AND LOW TEMPERATURES WILL BE AS MUCH AS 10 TO 15 DEGREES BELOW SEASONAL AVERAGES. FORECAST AFTER MONDAY WILL REMAIN DRY FOR NOW. && .PRELIMINARY POINT TEMPS/POPS...

SHOWERS AND THUNDERSTORMS WILL CONTINUE ALONG AND IN ADVANCE OF THE FRONT WITH A CONTINUING THREAT OF STRONG TO POSSIBLY SEVERE THUNDERSTORMS. THE BEST CHANCES OF SEVERE WEATHER WILL SHIFT TO EASTERN AND SOUTHEASTERN ARKANSAS WITH LARGE HAIL AND DAMAGING WINDS CONTINUING TO BE THE MAIN THREATS. SHOWERS AND ISOLATED THUNDERSTORMS WILL LINGER BEHIND THE FRONT THROUGH SATURDAY BUT THE CHANCES OF SEVERE WEATHER WILL BE MINIMAL. AT THIS TIME...THE HEAVY RAIN THREAT LOOKS MINIMAL...BUT A SLOWER FRONTAL PASSAGE COULD RESULT IN A MORE PROLONGED PERIOD OF RAIN FOR THE STATE.
