What was reported inside it

Time	Report	Where	Remark

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

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 Lubbock, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 27, 2:20 PM CDT, 3 hours 23 minutes earlier.

Area forecast discussion, May 27, 2:20 PM CDT, 3 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
220 PM CDT TUE MAY 27 2008

.SHORT TERM...
AS OF 1830Z...COLD FRONT STRETCHES FROM SE NM...NEWD THROUGH LUBBOCK
COUNTY INTO CHILDRESS COUNTY. THE FRONT HAS LOST MOST MOMENTUM AS
WINDS VEER TO THE NORTH OF THE BOUNDARY.  THE WIND SHOULD BECOME
GENERALLY E-NERLY ACROSS MOST OF THE FA THIS AFTERNOON...AND SHOULD
START TO ADVECT MOIST AIR WESTWARD. SAT/RADAR INDICATE ENHANCED CU
FIELD DEVELOPING IN CONVERGENT FLOW ALONG OUTFLOW BOUNDARIES IN
WESTERN OKLAHOMA AND ALSO ALONG THE FRONT...FROM THE CENTRAL SPLNS
EASTWARD. IN THIS AREA LAPS INDICATES SBCAPES UP TO 2K WITH CINH
LESS THAN 100 AND DECREASING QUICKLY. LARGE SCALE ASCENT NEARLY NIL
AS WTX IN WEAK SWERLY FLOW REGION AROUND UPPER HIGH. DEEP-LAYER
SHEAR DOES INCREASE NORTHWARD TOWARD THE WESTERN PANHANDLE WITH 30
KTS INDICATED ACROSS OUR NW ZONE. THINKING IS THAT CONVERGENCE/LIFT
ALONG THE FRONT WILL BE SUFFICIENT FOR TSTM DVLPMNT WITHIN NEXT
SEVERAL HRS. THE STRONG INSTABILITY JUST SOUTH OF THE FRONT SHOULD
RESULT IN RAPID INTENSIFICATION OF SOME STORMS WITH A FEW LIKELY
PRODUCING LARGE HAIL. GIVEN THE STEEP LOW-LVL LAPSE RATES AND
INSTABILITY...AN ISOLATED LANDSPOUT-TYPE TORNADO MAY BE POSSIBLE
DURING THE INTENSIFICATION STAGE OF ANY TSTM UPDRAFTS ALONG THE
BOUNDARY...BUT WEAK SHEAR SHOULD KEEP THE OVERALL TORNADO THREAT
MINIMAL. THE NAM AND GFS GUIDANCE INDICATE THAT THE ACTIVITY WILL
GROW UPSCALE INTO A MCS WHICH WILL MOVE SEWD ACROSS THE EASTERN
SOUTH PLAINS AND ROLLING PLAINS TONIGHT. GIVEN THE WEAK STEERING
FLOW AND DEEPER MOISTURE FURTHER EAST...HIGH PRECIP RATES/LOCALIZED
FLOODING MAY BE POSSIBLE WITH THIS ACTIVITY. FURTHER WEST...MUCH OF
THE SW PANHANDLE AND WESTERN SPLNS WILL INITIALLY BE COOLER AND
DRIER BEHIND THE FRONT...LIMITING INSTABILITY AND TSTM CHANCES. BUT
WILL STILL RETAIN POPS FURTHER WEST THOUGH AS THE UPSLOPE FLOW
SHOULD BE ABLE TO BRING MODERATE AMOUNTS OF MOISTURE TO THE WESTERN
COUNTIES THROUGH THE EVENING HRS...SO CANNOT RULE OUT SOME STORMS
THERE EITHER.

OTHERWISE...SE FLOW SHOULD KEEP LOW-LVL MOIST TONIGHT AND WEDNESDAY.
UPPER RIDGE BUILDS OVER WTX WHICH SHOULD SUPPRESS LCL TSTM
DEVELOPMENT. TSTMS ARE EXPECTED TO DEVELOP IN THE UPSLOPE FLOW
ACROSS THE HIGHER TERRAIN OF NM...WHICH WILL THEN DRIFT TOWARD THE
TX/NM BORDER BY EARLY EVENING.

.LONG TERM...
HIGH PRESSURE CONTINUES IN PLACE THURSDAY BUT CONVECTION MAY
DEVELOP OVER THE HIGHER TERRAIN OF NEW MEXICO AND APPROACH THE
WESTERN SOUTH PLAINS THURSDAY EVENING. THE BULK OF THIS ACTIVITY
IS EXPECTED TO REMAIN OVER NEW MEXICO.

BRIEF SEVERE WEATHER RESPITE APPEARS TO BE IN STORE FOR THE END OF
THE WORKWEEK AND INTO THE EARLY PART OF NEXT WEEK AS STOUT UPPER
LEVEL RIDGING REMAINS IN PLACE. STILL COULD SEE ISOLATED
THUNDERSTORM CHANCES MAINLY OVER THE WESTERN SOUTH PLAINS AND
EXTREME SOUTHWEST PANHANDLE AS WEAK IMPULSES ALOFT INFRINGE UPON
THE WESTERN PERIPHERY OF THE RIDGE BUT WARMING MID LEVEL TEMPS
KEEP ENOUGH UNCERTAINTY TO LEAVE POPS BELOW MENTION.

WEAK COLD FRONT PROGGED BY GFS AND ECMWF TO APPROACH THE SOUTH PLAINS
ON SATURDAY. DEPENDING ON THE STRENGTH OF THE RIDGE AND MID LEVEL
TEMPS...COULD SEE ISOLATED CONVECTION BUT WILL LEAVE OUT ATTM.

SIDED CLOSE TO MEX GUIDANCE THROUGH THE MIDDLE OF NEXT WEEK WITH
DAYTIME MAXIMA FROM THE LOWER TO MIDDLE 90S OVER THE NORTHWEST TO
THE MIDDLE 90S TO NEAR 100 DEGREES FROM AROUND I-27 EAST THROUGH
THE ROLLING PLAINS.   KW

1135 AM CDT TUE MAY 27 2008

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE EXTREME SOUTHERN TEXAS
PANHANDLE...SOUTH PLAINS AND ROLLING PLAINS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

CONVECTIVE

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING AS A COLD FRONT MOVES INTO AN UNSTABLE AIRMASS ACROSS WEST
TEXAS. STRONG INSTABILITY WILL DEVELOP THIS AFTERNOON WITH LIFT FROM THE
COLD FRONT AND WARM SURFACE TEMPERATURES POSSIBLY LEADING TO RAPID
GROWTH OF CONVECTIVE CELLS. ALTHOUGH DEEP LAYER SHEAR WILL BE LOW
BECAUSE OF AN UPPER LEVEL RIDGE ACROSS THE SOUTH PLAINS...FAVORABLE
LOW LEVEL SHEAR COMBINED WITH THE INSTABILITY MAY ALLOW A FEW
SUPERCELL THUNDERSTORMS TO DEVELOP. LARGE HAIL AND DAMAGING WIND
GUSTS WILL BE THE PRIMARY THREATS ALTHOUGH AN ISOLATED TORNADO IS
ALSO POSSIBLE ALONG THE FRONT...WHICH WILL STRETCH FROM THE
WESTERN SOUTH PLAINS INTO THE NORTHERN ROLLING PLAINS. THE
THUNDERSTORMS MAY FORM A COMPLEX THIS EVENING AND MOVE SOUTHEAST
THROUGH THE ROLLING PLAINS. THE THREAT OF SEVERE WEATHER WILL
DIMINISH OVERNIGHT BUT DEEP MOISTURE IN THIS AREA AND SLOW
MOVEMENT OF THE STORMS MAY RESULT IN LOCALIZED FLOODING.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

UPSLOPE EASTERLY FLOW AND AN UNSTABLE ATMOSPHERE MAY PRODUCE A FEW
SEVERE THUNDERSTORMS OVER THE HIGHER TERRAIN OF EASTERN NEW MEXICO
LATE WEDNESDAY AFTERNOON. THESE STORMS MAY THEN MOVE INTO WESTERN
SECTIONS OF THE SOUTH PLAINS AND EXTREME SOUTHWEST TEXAS PANHANDLE
DURING THE EVENING.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS LIKELY AFTERNOON AND EVENING.
