AS EXPECTED...THE MORNING CONVECTION OVER NE TX HAS DIMINISHED AS OF MID-AFTERNOON...AND ACTUALLY HAS BUILT W ALONG THE RED RIVER BORDERING SRN OK/N TX...NOT BEFORE DUMPING ANOTHER ESTIMATED 3-6 INCHES OF RAIN NEAR THE LAKE TEXOMA REGION...RESULTING IN ANOTHER ROUND OF FLASH FLOODING FOR THIS AREA LATE THIS MORNING/EARLY AFTERNOON. VISIBLE SATELLITE IMAGERY DOES REVEAL WHAT COULD BE A MCV SPINNING NEAR DAL...WITH AN ORGANZIED BAND OF CONVECTION HAVING RECENTLY DEVELOPED ON ITS ERN SIDE AND ADVANCING NE TOWARDS THE I-30 CORRIDOR OF NE TX. THE AIR MASS TO THE NE REMAINS SOMEWHAT STABILIZED N OF I-30 TO THE RED RIVER FROM RAINS RECEIVED EARLIER TODAY...ALTHOUGH IT/S POSSIBLE IT COULD CONTINUE TO EXPAND NE ACROSS NE TX LATE THIS AFTERNOON/EARLY EVENING IN VC OF THE WEAK TROUGH AXIS WHICH STILL REMAINS OVER EXTREME ERN OK INTO ECNTRL TX. OF COURSE...THE SHORT TERM PROGS ARE NOT HANDLING THE ONGOING CONVECTION WELL AT ALL...AND THUS HAVE INSERTED CHANCE POPS THIS EVENING FOR NE TX NEAR I-30...AND BLANKETING MUCH OF THE REMAINDER OF THE AREA WITH SLIGHT CHANCE POPS GIVEN THAT VISIBLE SATELLITE IMAGERY REVEALS A SOME CU TOWERS DEVELOPING OVER THE REST OF E TX/WRN LA/SW AR. MUCH OF THIS SHOULD REMAIN DIURNAL IN NATURE...GRADUALLY DIMINISHING DURING THE EVENING WITH THE LOSS OF HEATING. HOWEVER...THE SHORT TERM PROGS DO MAINTAIN THE WEAK SHEAR AXIS IN PLACE OVER NE TX/EXTREME SE OK/SW AR OVERNIGHT...WHICH MAY RESULT IN ISOLATED CONVECTION REDEVELOPING. CONVECTIVE DEBRIS AND LIGHT S WINDS SHOULD HELP MAINTAIN VERY MUGGY CONDITIONS OVERNIGHT...WITH TEMPS NOT FALLING MUCH BELOW THE MID 70S. THE WEAK SHEAR AXIS SHOULD ERODE AFTER DAYBREAK MONDAY AS THE TROUGH RETROGRADES SW TOWARDS THE RIO GRANDE VALLEY BY AFTERNOON...WITH THE FLAT FOUR CORNERS UPPER RIDGING EXPANDING E TOWARDS THE MS RIVER.

THE SSE FLOW LOOKS TO DEEPEN AREAWIDE WEDNESDAY...WHICH MAY RESULT IN ISOLATED CONVECTION AREAWIDE AS THE RIDGE EXPANDS INTO THE SE CONUS. AFTERWARDS...SUBSIDENCE WITH THE RIDGE SHOULD INHIBIT CONVECTION OVER MUCH OF THE REGION THURSDAY AND FRIDAY...BEFORE A PATTERN CHANGE BEGINS TO TAKE SHAPE BY THE START OF NEXT WEEKEND. BOTH THE GFS/ECMWF ARE IN GOOD AGREEMENT WITH A 597DM RIDGE DEVELOPING LATE FRIDAY OVER THE GREAT BASIN...BEFORE EXPANDING N ACROSS THE NRN ROCKIES/WRN GREAT PLAINS LATE SATURDAY. THIS RIDGE SHOULD CARVE A LONGWAVE TROUGH E OF THE ROCKIES BY LATE NEXT WEEKEND...NUDGING A WEAK SFC TROUGH S TOWARDS THE RED RIVER VALLEY EARLY NEXT WEEK. SCT CONVECTION WILL AGAIN BE POSSIBLE LATE SATURDAY THROUGH THE REMAINDER OF THE WEEKEND AS THIS TROUGH SLOWLY SINKS S THROUGH THE REGION. HAVE ADDED LOW CHANCE AND SLIGHT CHANCE POPS TO THE FORECAST FOR THIS TIME PERIOD...WITH COOLER TEMPS EXPECTED GIVEN THE INCREASED CLOUD COVER/CONVECTION.
