NWS Amarillo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 3, 4:19 PM CDT, 2 hours earlier.
Area forecast discussion, Jun 3, 4:19 PM CDT, 2 hours 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.
