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 Austin/San Antonio, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 8, 11:59 PM CST, 37 minutes earlier.

Area forecast discussion, Mar 8, 11:59 PM CST, 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
1159 PM CST TUE MAR 8 2016

.AVIATION...
CONVECTION BEGINNING TO TRANSITION FROM THE STRONGER DISCRETE
CELLS TO BROADER AREAS OF RAIN AND THUNDERSTORMS. STILL EXPECT
SOME AREAS OF HEAVY RAINFALL RATES TO REDUCE VSBYS TO LESS THAN 1
MILE...BUT THERE IS AN INCREASING AREA OF COVERAGE TO SHOW LIGHT
TO MODERATE RAIN AND OCCASIONAL THUNDER. THUS WILL RUN SEVERAL
HOURS OF MINOR VSBY RESTRICTIONS AND KEEP PREVAILING CONDITIONS AS
MVFR ALONG WITH CIGS. AS THE STRONGER CONVECTIVE FOCUS SHIFTS
GRADUALLY EAST OVERNIGHT...SHOULD SEE A DECREASE IN THUNDER ALONG
I-35 TERMINALS BETWEEN 09Z AND 10Z. ISOLATED CLAPS OF THUNDER MAY
THREATEN DRT DURING THIS PERIOD...BUT WITH COVERAGE TOO LOW TO
MENTION. THE UPPER LOW WILL CONTINUE TO PASS SLOWLY SOUTH OF TX
WITH NORTHERLY SURFACE WINDS EXPECTED TO PICK UP IN THE EARLY
MORNING HOURS. THE EASTWARD MOVEMENT OF CONVECTION AND NORTHERLY
BREEZES SHOULD HELP IMPROVE CIG HEIGHTS...BUT THE CHANCE FOR MORE
RAINS MAY NOT GO COMPLETELY AWAY THROUGH THE REST OF THE TAF
PERIOD.

&&

.PREV DISCUSSION... /ISSUED 950 PM CST TUE MAR 8 2016/

MESOSCALE UPDATE...
ENVIRONMENT CONTINUES TO BE CONDUCIVE FOR LARGE HAIL AND ISOLATED
TORNADOES THIS EVENING THROUGH AT LEAST MIDNIGHT.

CONVECTION CONTINUES TO BE LOCATED EAST OF A DRY LINE POSITIONED
ALONG THE RIO GRANDE PLAINS. STRONGEST CELLS CONTINUE TO BE FED BY
STRONG THETA-E ADVECTION AND INCREASING UPPER LEVEL DIVERGENT
FLOW. THERE STILL REMAINS A VERY IMPRESSIVE INSTABILITY AXIS IN
THE WARM SECTOR EAST OF THE DRY LINE AND THE RAP IS INDICATING LOW
LEVEL LAPSE RATES OF 7+ DEG C/KM IN THIS REGION AS WELL. THIS
SHOULD MAINTAIN THE THREAT FOR SEVERE HAIL AND EXTREME LIGHTNING.
TORNADO POTENTIAL REMAINS LOW BUT AS THESE CELLS PUSH SLOWLY
FARTHER EAST...THEY WILL BE INTERACTING WITH A MORE FAVORABLE LCL
ENVIRONMENT WHICH WILL MEANS THE TORNADIC POTENTIAL WILL GRADUALLY
INCREASE OVER THE NEXT FEW HOURS.

REGARDING FLOOD POTENTIAL...RAINFALL HAS BEEN MOSTLY FOCUSED ALONG
A LINE FROM CENTRAL DIMMITT COUNTY NORTH THROUGH REAL COUNTY.
WHILE THE PLATEAU COUNTIES SHOULD AVOID MUCH IN THE WAY OF FLASH
FLOOD POTENTIAL NOW THAT THE MAJORITY OF THE ACTIVITY HAS SHIFTED
EAST...ADDITIONAL DEVELOPMENT ONGOING SOUTH OF DIMMITT AND ZAVALA
INDICATES AN INCREASING FLASH FLOOD THREAT WITH RAIN RATES OF UP
TO 2 INCHES PER HOUR POSSIBLE WITH FUTURE CELLS.

THIS ACTIVITY IS STILL EXPECTED TO BECOME LINEAR AND PUSH EAST
TOWARDS THE INTERSTATE 35 CORRIDOR AROUND THE MIDNIGHT HOUR
HOWEVER VAD WIND PROFILES MAINTAIN A SOUTHERLY FLOW REGIME LIKELY
DELAYING THE EASTWARD PROGRESSION OF THE LINE. AS SUCH...NO
CHANGES TO THE CURRENT WATCH ARE EXPECTED BUT WILL NEED TO RE-
EVALUATE IN A FEW HOURS AS THIS CONTINUES TO SLOWLY PUSH EAST.
