01Z SFC ANALYSIS SHOWS A BOWED DRYLINE MOVING INTO THE FAR EASTERN
CWA. ADAP ESTIMATED SURFACE-BASED LIFTED INDICES EAST OF THE DRYLINE
WERE NEAR -11C. VILS OF 80+ WERE VERY COMMON WITH THE HEARTLAND
STORMS THE PAST 3 HOURS.

SECONDARY PUSH OF DRY AIR IS EVIDENT ON THE KSJT RADAR ENTERING IRION
AND COKE COUNTIES. ISOLATED HIGH-BASED THUNDERSTORMS WERE MOVING INTO
IRION COUNTIES. THESE MAY BRIEFLY PULSE WITH INTERACTION OF THE

ISOLATED STORMS TO DISSIPATE THROUGH LATE EVENING. CAN PROBABLY
DROP/REDUCE POPS OVER THE CONCHO/EASTERN BIG COUNTRY ZONES LATER THIS
EVENING...PENDING RADAR TRENDS.
