.DISCUSSION...
UPPER TROF MOVING ACROSS THE CENTRAL PLAINS THIS AFTERNOON WILL
REACH THE TENNESSEE VALLEY BY TUESDAY AFTERNOON. THIS SHOULD HELP
WEAKEN AND SHOVE THE UPPER RIDGE WHICH HAS LINGERED OVER THIS
REGION PAST FEW DAYS INTO WEST TEXAS. THE WEAK CONVERGENCE ZONE
WHICH WORKED SOUTH INTO THE CWA THIS MORNING...RETREATED NORTH
SOME THIS AFTERNOON. THIS HAS RESULTED IN SCATTERED CONVECTION
ACROSS SOUTHEAST OKLAHOMA AND ADJACENT AREAS OF NORTHEAST
TEXAS...EASTWARD ACROSS SOUTHWEST ARKANSAS. ALSO...ISOLATED
CONVECTION WAS DEVELOPING ACROSS NORTHCENTRAL LA. WILL GO WITH THE
HIGHEST POP...30 PERCENT...TONIGHT IN THESE AREAS...AS BOUNDARIES
LINGER FROM AFTERNOON ACTIVITY. THINKING IS THAT MOST WILL BE GONE
BY MIDNIGHT...BUT LEAVING SAME POP THROUGHOUT ALL OF TONIGHT WITH
THE UPPER TROF POSSIBLY KEEPING SOME LIFT GOING. EVENING SHIFT
CAN ADJUST AS NEEDED. ON TUESDAY...LOT OF UNCERTAINTY ON WHERE THE
BOUNDARY WILL BE LOCATED...AND MODELS DO NOT AGREE. NAM IS FAIRLY
WET ACROSS ALL OF THE CWA WHILE THE OLD NGM IS DRIEST. WILL GO
WITH THE NGM...AS IT WAS INITIALIZING TODAYS CONVECTION THE BEST.
THE CONVERGENCE BOUNDARY BEGINS TO SINK SOUTHWEST WITH DRIER AIR
MOVING IN FROM THE NORTHEAST WEDNESDAY. WILL GRADUALLY DECREASE
POPS WITH TIME...AND CARRY ONLY DIURNAL SLIGHT CHANCE POPS FROM
THURSDAY THROUGHOUT REMAINDER OF FORECAST. TEMPS WILL MODERATE
SOME OVER THE NEXT FEW DAYS WITH LIGHT EAST TO NORTHEAST WINDS.
WINDS RETURN TO SOUTHERLY BY THE WEEKEND...WITH READINGS A LITTLE
WARMER. HOWEVER...WITH THE STRONG SUBSIDENCE FROM UPPER RIDGE...
TEMPS SHOULD HOLD BELOW THE 100 DEGREE MARK.
