DISCUSSION...
COLD FRONT HAS STALLED NEAR A DRYDEN TO MASON TO WACO LINE WHILE
A SHORT-WAVE APPROACHES THE RIO GRANDE. THERE WAS A BAND OF
SHOWERS AND STORMS ALONG AND JUST AHEAD OF THE PART OF THE FRONT
EAST OF MASON WITH BANDS OF SHOWERS ELSEWHERE ACROSS SOUTH CENTRAL
TEXAS. THE SHORT-WAVE WILL MOVE ACROSS TEXAS TODAY AS THE FRONT
MEANDERS SLIGHTLY INTO TONIGHT. EXTENSIVE CLOUD COVER SHOULD
INHIBIT STRONG/SEVERE STORM POTENTIAL WHILE LOCALLY HEAVY RAINFALL
IS POSSIBLE MAINLY IN THE BAND AS IT DRIFTS TO THE SOUTHEAST. POPS
DECREASE LATER TODAY AS THE SHORT-WAVE MOVES EAST OF THE AREA,
THEN INCREASE AGAIN TONIGHT AS SHORT-WAVE CURRENTLY NEARING BAJA
CALIFORNIA MOVES TOWARD TEXAS AND THEN ACROSS ON WEDNESDAY. AGAIN
EXTENSIVE CLOUDINESS WILL INHIBIT STRONG/SEVERE POTENTIAL WITH
ISOLATED HEAVY RAINFALL THE MAIN THREAT. LARGE UPPER TROUGH
CURRENTLY APPROACHING THE WEST COAST WILL MOVE ACROSS THE ROCKIES
AND INTO THE CENTRAL PLAINS AND TO THE UPPER MIDWEST/GREAT LAKES
ON THURSDAY. A DRYLINE/PACIFIC FRONT MAY DRIFT INTO SOUTH CENTRAL
TEXAS WITH A SLIGHT CHANCE POPS DUE TO POSSIBLE SQUALL LINE MOVING
ACROSS ON THURSDAY WITH A BETTER CONDITIONAL THREAT OF STRONG TO
SEVERE STORMS. OVER THE WEEKEND AND INTO NEXT WEEK, ANOTHER COOL
FRONT MAY SAG INTO THE AREA AS A COUPLE OF SHORT-WAVES MOVE ACROSS
THE CENTRAL AND NORTHERN PLAINS WITH MAINLY A SLIGHT CHANCE POPS.
TEMPERATURES OVER THE NEXT FEW DAYS WILL REFLECT A BLEND OF
MAV/MET/MEX GUIDANCE.
