.DISCUSSION...
SOMEWHAT OF A WET PATTERN SETTING UP FOR PARTS OF THE CWA TO
BEGIN THE SEVEN DAY FORECAST PERIOD. A TROUGH...CURRENTLY IN THE
SOUTHERN ROCKIES WILL BEGIN TO TRANSITION EAST...WITH ISOLATED
CONVECTION POSSIBLE NORTHWEST ZONES LATER TODAY. BY TONIGHT...THE
TROUGH WILL TAKE ON A SLIGHT POSITIVE TILT OVER OKLAHOMA INTO WEST
TEXAS. THIS WILL RESULT IN INCREASED LIFT AND MOISTURE IN THE
NORTHWEST ZONES...WITH HIGHER RAIN CHANCES. SLOW MOVEMENT THROUGH
MONDAY WILL BRING HIGHER POPS TO OTHER AREAS...BUT WITH THE HIGHER
QFP REMAINING ACROSS THE NORTHERN ZONES. THIS SYSTEM WILL EXIT
EAST EARLY ON TUESDAY...WITH THE HIGHEST QFP OF ONE HALF TO
LOCALLY ONE INCH ALONG THE I-30 CORRIDOR. THIS AREA WILL ALSO HAVE
THE BEST CHANCE OF SEVERE WEATHER MONDAY AFTERNOON INTO MONDAY
NIGHT WHERE LARGE SCALE ASCENT BECOMES MORE FOCUSED. HOWEVER...
LOW LEVEL SHEAR WILL BE WEAK...SO WIDESPREAD SEVERE WEATHER LOOKS
UNLIKELY. A COLD FRONT WILL FOLLOW THE TROUGH ON TUESDAY...
BRINGING DRIER AIR TO THE FOUR STATE REGION BUT ONLY A MINOR AND
SHORT LIVED TEMPERATURE DROP. SURFACE WIND WILL RETURN TO SOUTHEAST
ON WEDNESDAY AS A HIGH MOVES INTO THE MISSISSIPPI VALLEY.

ANOTHER SYSTEM WILL APPROACH THE AREA THURSDAY. HOWEVER...MOISTURE
WILL BE RATHER LACKING AND MOST OF THE DYNAMICS WILL REMAIN WELL
NORTH OF THE CWA. HOWEVER...SCATTERED CONVECTION IS POSSIBLE
THURSDAY INTO THURSDAY EVENING WITH BEST CHANCES IN THE NORTHWEST.
THE REMAINDER OF THE SEVEN DAY FORECAST PERIOD LOOKS DRY.

TEMPERATURES THROUGHOUT THE SEVEN DAYS WILL BE AT OR SLIGHTLY
ABOVE SEASONAL AVERAGES AS UPPER FLOW REMAINS MOSTLY SOUTHWEST.
