.DISCUSSION...
ONCE AGAIN TODAY...SHOWERS AND THUNDERSTORMS HAVE INVADED FROM
SOUTH TEXAS...BEING GUIDED PRIMARILY BY SOUTHERLY LOW-LEVEL FLOW.
BUT UNLIKE TUESDAY...RIDGING ALOFT IS BUILDING INTO THE REGION
FROM THE NORTHWEST. ALTHOUGH INSTABILITY STEADILY DECREASES
DOWNSTREAM OF THE ONGOING ACTIVITY...UNCAPPED MLCAPE VALUES OF
1000-1500J/KG ARE IN PLACE ACROSS THE REMAINDER OF NORTH TEXAS.
DESPITE THIS UNSTABLE BOUNDARY LAYER...THE INCREASING SUBSIDENCE
SHOULD PREVENT THE CONVECTION FROM PENETRATING MUCH FURTHER INTO
THE CWA. THE ONGOING ACTIVITY ALSO APPEARS TO BE SUFFERING FROM
SOME DOWNGLIDE...WHICH IS LIMITING THE DEPTH OF THE UPDRAFTS...
EVIDENCED BY THE DECREASE IN LIGHTNING. NONETHELESS...THESE CELLS
MAY STILL PRODUCE GUSTY WINDS AT THE SURFACE. THE ACTIVITY WILL
DISSIPATE BY NIGHTFALL WITH THE LOSS OF DAYTIME HEATING.

THURSDAY STILL APPEARS TO BE A RAIN-FREE DAY REGIONWIDE AS THE
MID- AND UPPER-LEVEL RIDGE AXES SLIP INTO SOUTH TEXAS...LIMITING
BOTH CONVECTIVE INITIATION IN NORTH TEXAS AND UPSTREAM
DEVELOPMENT. HOWEVER...THE ONSET OF NORTHWEST FLOW MAY ALLOW FOR
DAYTIME ACTIVITY IN THE CENTRAL HIGH PLAINS TO ARRIVE LATE
THURSDAY NIGHT. THE STRENGTH OF THE FRIDAY SHORTWAVE CONTINUES TO
WANE WITH SUCCESSIVE MODEL RUNS...BUT THERE SHOULD BE WIDESPREAD
SHOWERS AND STORMS ALONG THE RED RIVER FRIDAY MORNING...WITH A
POTENTIAL FOR AFTERNOON REDEVELOPMENT ON LINGERING BOUNDARIES.
RIDGING TO THE SOUTH SHOULD PREVENT ANY SHOWERS/STORMS SOUTH OF
THE I-20 CORRIDOR.

NORTHWEST FLOW WILL CONTINUE SATURDAY AND SUNDAY...WHICH WILL
MAINTAIN RAIN CHANCES...MAINLY NORTH AND EAST. EACH DAY...THERE
WILL BE A CHANCE FOR ACTIVITY SLIDING ACROSS THE RED RIVER DURING
THE MORNING HOURS...THOUGH THE FLOW ABOVE THE NOCTURNAL BOUNDARY
LAYER DOES NOT LOOK TO BE PARTICULARLY IMPRESSIVE. EACH
AFTERNOON...THERE WILL BE LOW CHANCES FOR REDEVELOPMENT...WHICH
WILL REQUIRE THOSE ENGAGED IN OUTDOOR ACTIVITIES TO MAINTAIN
SITUATIONAL AWARENESS...BUT NEITHER DAY LOOKS TO BE A WASHOUT.
SUBTROPICAL RIDGING WILL TAKE HOLD BY MONDAY AND DOMINATE TEXAS
WEATHER NEXT WEEK.

.AVIATION...
/ISSUED 1223 PM CDT WED JUL 1 2015/
LARGE SCALE SUBSIDENCE OVER NORTH TEXAS SHOULD SUPPRESS MOST
CONVECTION TODAY THROUGH THURSDAY. THE ONLY EXCEPTION WILL BE SOME
SCATTERED AFTERNOON SEA BREEZE CONVECTION THAT MAY MOVE INTO THE
SOUTHEAST PORTIONS OF NORTH TEXAS. THIS ACTIVITY SHOULD REMAIN
SOUTH AND EAST OF WACO.

EXPECT VFR CONDITIONS TO PERSIST THROUGH THURSDAY AFTERNOON WITH
SCATTERED DAYTIME CU AND SCATTERED TO BROKEN HIGH CLOUDS.

A SOUTH TO SOUTHWEST WIND WILL PREVAIL THROUGH THURSDAY. DAYTIME
WIND SPEEDS WILL RANGE FROM 12 TO 16 KNOTS ALONG WITH SOME
OCCASIONAL HIGHER GUSTS. WIND SPEEDS TONIGHT/EARLY THURSDAY
MORNING SHOULD BE BETWEEN 8 TO 12 KNOTS.
