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.

The nearest sounding before it

Amarillo Airport, TX (KAMA), launched 00:00Z, 1.9 hours before the alert went out and 34 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.

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 Amarillo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 3, 4:19 PM CDT, 4 hours 37 minutes earlier.

Area forecast discussion, Jun 3, 4:19 PM CDT, 4 hours 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
412 PM CDT TUE 03 JUN 2003

EXCELLENT DIRECTIONAL SHEAR AND MARGINAL SPEED SHEAR COULD RESULT IN
SHORT-LIVED TORNADOES...MAINLY SOUTHWEST TEXAS PANHANDLE. LIMITING
FACTOR WILL BE THE LACK OF INSOLATION DUE TO CLOUD COVER MOST OF
THE DAY. BETTER SETUP FOR HEAVY RAIN PRODUCERS AS FRONTAL BOUNDARY
STRETCHES NORTHWEST TO SOUTHEAST ACROSS THE PANHANDLE REGION. MOIST
CONVERGENCE NORTH AND EAST OF THIS BOUNDARY WILL SUSTAIN NOCTURNAL
THUNDERSTORMS THAT DEVELOP AHEAD OF APPROACHING WIND SPEED MAXIMUM.

THIS PATTERN PERSISTS INTO THE WEEKEND...SO NO SIGNIFICANT CHANGES
ANTICIPATED. UPPER RIDGE FLATTENS EARLY NEXT WEEK AND INTRODUCES
WARMUP AND DRIER CONDITIONS.
