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.

Area forecast discussion, Apr 10, 7:24 PM CDT, 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
724 PM CDT SUN APR 10 2016

.MESOSCALE UPDATE...
LATEST SURFACE OBSERVATIONS FROM THE WEST TEXAS MESONET SITES EAST
AND SOUTH OF THE BAND OF CONVECTION EXTENDING FROM NEAR CLARENDON
BACK TO WAYSIDE STILL SHOWS LIGHT WINDS AND DRY AIR. DEW POINTS ARE
IN THE LOW TO MID 40S AT MCLEAN...MEMPHIS...AND SILVERTON. SHORT TERM
MODEL GUIDANCE SUGGESTS SOUTHEASTERLY WINDS WILL STRENGTHEN SLIGHTLY
OVER THE SOUTHEAST TEXAS PANHANDLE OVER THE NEXT COUPLE OF HOURS.
THIS SHOULD ADVECT MID 50 TO LOWER 60 DEGREE DEW POINTS CURRENTLY
OBSERVED AT CHILDRESS AND NORTHFIELD NORTH-NORTHWESTWARD INTO THE
SOUTHEAST TEXAS PANHANDLE OFFSETTING NOCTURNAL COOLING THROUGH THE
EVENING HOURS TO KEEP THIS AREA AT LEAST MODESTLY UNSTABLE. 00Z KAMA
SOUNDING SHOWS COOLER MID LEVELS AND AN UNCAPPED THERMAL PROFILE AS
EXPECTED WITH THE APPROACH OF THE MID-UPPER TROUGH. THE COMBINATION
OF LOW LEVEL MOIST ADVECTION ACROSS THE FAR SOUTHEAST PANHANDLE AND
COOLER MID LEVEL AIR MASS OVERSPREADING THE AREA SHOULD KEEP THE
MARGINAL SEVERE THREAT GOING THROUGH THE EVENING...GENERALLY EAST OF
A LINE FROM CLARENDON TO WHEELER. MARGINALLY SEVERE HAIL AND WIND ARE
THE PRIMARY THREATS HERE. STRENGTHENING LOW LEVEL JET AND RESULTANT
INCREASE OF LOW LEVEL SHEAR SHOULD BE JUST TO THE EAST OF OUR
FORECAST AREA AND THIS WILL BE WHERE THE HIGHER SEVERE POTENTIAL WILL
BE THIS EVENING. WE WILL REMOVE POTTER RANDALL AND CARSON COUNTIES
FROM THE SEVERE THUNDERSTORM WATCH SHORTLY.

.PREV DISCUSSION... /ISSUED 636 PM CDT SUN APR 10 2016/

AVIATION...
00Z TAF CYCLE

AN UPPER TROUGH WILL APPROACH THE PANHANDLES THROUGH TONIGHT AND THEN
WILL MOVE ACROSS THE PANHANDLES MONDAY. A COLD FRONT WILL TRACK SOUTH
ACROSS THE THREE TAF SITES BY 05Z MONDAY. SOUTH TO SOUTHEAST WINDS 10
TO 20 KNOTS WITH SOME GUSTS WILL BACK AROUND TO THE EAST AND
NORTHEAST ONCE THE COLD FRONT MOVES THROUGH. NORTH AND NORTHEAST
WINDS WILL INCREASE TO 15 TO 25 KNOTS WITH HIGHER GUSTS AT THE GUYMON
AND DALHART TAF SITES BY 08Z TO 10Z MONDAY...AND THEN AT THE AMARILLO
TAF SITE BY 13Z TO 15Z MONDAY. VFR CONDITIONS ARE EXPECTED TO BECOME
MVFR TO IFR IN AND NEAR ANY CONVECTION TONIGHT AND MONDAY...AND WILL
REMAIN MVFR THROUGH 00Z TUESDAY.

SCHNEIDER

PREV DISCUSSION... /ISSUED 335 PM CDT SUN APR 10 2016/

DISCUSSION...
DRIER AIR HAS SPREAD ACROSS THE PANHANDLES THIS AFTERNOON. DEW
POINTS RANGE FROM NEAR 10 DEGREES IN THE NORTHWEST TO NEAR 50
DEGREES IN THE SOUTHEAST. A DRYLINE IS FOUND NEAR THE WEST
TEXAS/SOUTHEAST NEW MEXICO STATE LINE BETWEEN ROW AND TAT NORTHEAST
TO BETWEEN MUS AND AMH. THE DRYLINE GETS MUCH MORE DIFFUSE AS IT
SNAKES ITS WAY FROM THE NORTHERN SOUTH PLAINS INTO SOUTHWEST
OKLAHOMA.  THUNDERSTORMS HAVE ALREADY DEVELOPED NEAR LUB THIS
AFTERNOON IN ASSOCIATION WITH A LEAD SHORT WAVE TROUGH MOVING
NORTHEAST FROM SOUTHEAST NEW MEXICO. ACCORDING TO THE SHORT RANGE
MODELS...THESE STORMS ARE EXPECTED TO CONTINUE TO MOVE NORTHEAST
INTO THE SOUTH CENTRAL AND SOUTHEAST TEXAS PANHANDLE WHERE THEY WILL
ENCOUNTER MORE INSTABILITY AND SHEAR. THE STORMS ARE EXPECTED TO
INTENSIFY THROUGH THE LATE AFTERNOON. SO WE ARE STILL EXPECTING SOME
SEVERE STORMS ACROSS THE SOUTH CENTRAL AND SOUTHEAST TEXAS PANHANDLE
LATER THIS AFTERNOON AND EARLY THIS EVENING. LARGE HAIL AND DAMAGING
WINDS LOOK TO BE THE MAIN THREATS. STILL CAN NOT RULE OUT A TORNADO.
HOWEVER...THAT THREAT LOOKS LIKE IT MAY BE A LITTLE FURTHER SOUTH AND
EAST. MORE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG
THE TEXAS PANHANDLE/NEW MEXICO STATE LINE AS THE MAIN LIFT AHEAD OF
THE PARENT UPPER LOW STARTS TO SPREAD ACROSS THIS AREA. THESE
SHOWERS AND STORMS ARE EXPECTED TO LIFT NORTHEAST OVERNIGHT AND
AFFECT MAINLY THE NORTHERN CWA. A COLD FRONT WILL MOVE SOUTH ACROSS
THE PANHANDLES MONDAY MORNING. MORE SHOWERS MAY FILTER IN BEHIND
THIS FRONT AS IT MOVES SOUTH. HOWEVER...STILL THINK THE BEST CHANCE
OF SHOWERS THROUGH MONDAY WILL BE ACROSS THE NORTH CLOSER TO THE
UPPER LEVEL DYNAMICS AS THE PARENT LOW KICKS OUT INTO THE CENTRAL
PLAINS.

THE NEXT UPPER LOW THAT MOVES INTO THE SOUTHWEST U.S. BY MONDAY
NIGHT IS EXPECTED TO KEEP MOST OF THE PRECIPITATION SOUTH OF OUR
AREA AS IT MOVES ACROSS SOUTHERN NEW MEXICO AND WEST TEXAS TUESDAY
AND TUESDAY NIGHT.

THE FORECAST WILL REMAIN DRY THROUGH THURSDAY. THEN THE NEXT SYSTEM
WILL START TO AFFECT OUR AREA. SHOWERS AND THUNDERSTORMS WILL ONCE
AGAIN BE POSSIBLE FRIDAY AND SATURDAY.
