NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in. Storm Data before 1996 records only tornadoes, thunderstorm wind and hail.

The nearest sounding before it

Amarillo Airport, TX (KAMA), launched 12:00Z, 10.8 hours before the alert went out and 142 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

TEXAS/OKLAHOMA PANHANDLES THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE AMARILLO TX
100 PM CDT MON MAY 9 1994

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT
ACROSS MOST OF THE TEXAS AND OKLAHOMA PANHANDLES EXCEPT FOR THE EXTREME
EASTERN OKLAHOMA PANHANDLE AND FAR NORTHEAST TEXAS PANHANDLE.

A WEAK COLD FRONT EXTENDED FROM NEAR DALHART TO AMARILLO TO NORTH OF
CHILDRESS EARLY THIS AFTERNOON AND IS EXPECTED TO MOVE ONLY SLOWLY SOUTH
THROUGH TONIGHT. SURFACE AND LOW LEVEL WINDS ACROSS THE PANHANDLES WILL
REMAIN EAST TO SOUTHEAST AND WILL CONTINUE TO INCREASE THE MOISTURE
SUPPLY.

SKIES HAD BECOME MOSTLY SUNNY ACROSS THE WESTERN HALF OF THE TEXAS
PANHANDLE. STRONG DAYTIME HEATING AND INCREASING LOW LEVEL MOISTURE WILL
MAKE THE ATMOSPHERE QUITE UNSTABLE IN THIS AREA LATER THIS AFTERNOON.

THE PERSISTENT UPPER LEVEL LOW WAS STILL IN ARIZONA AND WILL CONTINUE TO
EJECT WEATHER DISTURBANCES ACROSS THE PANHANDLES TODAY AND TUESDAY. ONE
OF THESE WEATHER DISTURBANCES WILL APPROACH THE AREA LATE THIS AFTERNOON
AND WILL LIKELY INITIATE THUNDERSTORMS ALONG THE COLD FRONT ACROSS THE
SOUTHWEST HALF OF THE TEXAS PANHANDLE OR IN EASTERN NEW MEXICO.

BECAUSE OF THE UNSTABLE ATMOSPHERE AND FAVORABLE WIND PROFILE...SOME OF
THE STORMS MAY BECOME SEVERE MAINLY THIS AFTERNOON AND THIS EVENING. THE
MAIN THREATS WILL BE HAIL AND STRONG WINDS. LOCALLY HEAVY RAINFALL IS
POSSIBLE AS THE STORMS ARE EXPECTED TO MOVE SLOWLY.

SPOTTER GROUPS AND EMERGENCY MANAGEMENT OFFICIALS ACROSS THE SLIGHT RISK
AREA SHOULD BE READY FOR POSSIBLE ACTIVATION THIS AFTERNOON AND TONIGHT.

SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN IN MOST AREAS TUESDAY
AFTERNOON AND EVENING WITH DAYTIME HEATING AND ANOTHER APPROACHING
WEATHER DISTURBANCE.
